TRANSCANADA
CORPORATION1   TRANSCANADA
CORPORATION  Corporate Structure  TransCanadas head office and registered
office are located at 450 - First Street S.W., Calgary, Alberta,
T2P 5H1. TransCanada was incorporated pursuant to the provisions of the CanadaBusiness
Corporations Act on February 25, 2003 in connection with a plan
of arrangement which established TransCanada as the parent company of TCPL. The
arrangement was approved by TCPL common shareholders on April 25, 2003
and, following court approval and the filing of Articles of Arrangement, the
arrangement became effective May 15, 2003. Pursuant to the arrangement,
the common shareholders of TCPL exchanged each of their TCPL common shares for
one common share of TransCanada. The debt securities and preferred shares of
TCPL remained obligations and securities of TCPL. TCPL continues to hold the
assets it held prior to the arrangement and continues to carry on business as
the principal operating subsidiary of the TransCanada group of entities.
TransCanada does not hold any material assets directly other than the common
shares of TCPL and receivables from certain of TransCanadas subsidiaries.  Intercorporate Relationships  The following diagram presents the name and
jurisdiction of incorporation, continuance or formation of TransCanadas
principal subsidiaries as at December 31, 2009.  Each of these subsidiaries has total assets
that exceeded 10% of the total consolidated assets of TransCanada or revenues
that exceeded 10% of the total consolidated revenues of TransCanada as at and
for the year ended December 31, 2009. 
TransCanada owns, directly or indirectly, 100 per cent of the voting
shares of each of these subsidiaries.    The above diagram does not include all of the
subsidiaries of TransCanada.  The assets
and revenues of excluded subsidiaries in the aggregate did not exceed 20% of
the total consolidated assets or total consolidated revenues of TransCanada as
at and for the year ended December 31, 2009.


TRANSCANADA CORPORATION     2   GENERAL DEVELOPMENT OF THE BUSINESS  The general development of TransCanadas
business during the last three financial years, and the significant
acquisitions, dispositions, events or conditions which have had an influence on
that development, are described below.  TransCanadas reportable business segments
are Pipelines and Energy. Pipelines are principally
comprised of the Companys pipelines in Canada, the U.S. and Mexico and its
regulated natural gas storage operations in the U.S. Energy includes the
Companys power operations and the non-regulated natural gas storage business.  Developments in the Pipelines Business  TransCanadas strategy in Pipelines is
focused on both growing its North American natural gas and crude oil
transmission network and maximizing the long-term value of its existing
pipeline assets. Summarized below are significant developments that have
occurred in TransCanadas Pipelines business over the last three years.  2010  Pipeline
Developments  ·January 29,
2010.  TransCanada announced that the
proposed Alaska pipeline project (the Alaska Pipeline Project)
filed its plan with the United States Federal Energy Regulatory Commission (FERC) to obtain approval to conduct an open season.  If approval is granted, an open season
offering is expected to be provided to potential shippers at the end of April 2010
for their assessment until July 2010.  
The Alaska Pipeline Project is a 4.5 billion cubic feet per day (Bcf/d) natural gas pipeline that would extend 2,737
kilometres (km) (1,700 miles) from a new
natural gas treatment plant at Prudhoe Bay, Alaska to Alberta.  Regulatory
Matters  ·February 19,
2010.TransCanada filed an application with the National Energy Board (NEB) for approvals to construct and operate the proposed
Horn River pipeline project (Horn River Project),
a 158 km (98 mile) pipeline and related facilities to connect new shale gas
supply in the Horn River basin north of Fort Nelson, B.C., to TransCanadas
natural gas transmission system in the province of Alberta (the Alberta System).  The
Horn River Project will consist of approximately 74 km of new pipelines and the
purchase and use of an existing pipeline in the Horn River area and will
transport sweet natural gas to a tie in point on the Alberta System.  The project is expected to cost approximately
$307 million.  2009  Pipeline
Developments  ·February 26, 2009.  TransCanada announced the successful
completion of a binding open season, securing support for firm transportation
contracts of 378 million cubic feet per day (MMcf/d)
for the Horn River Project.  Total
contractual commitments for the Horn River Project increased to 503 MMcf/d by
2014 as a result of newly contracted volumes from a recently announced natural
gas processing facility that will be located in the Horn River area.  ·May 7, 2009. 
TransCanada announced that it was the successful bidder on a contract to
build, own and operate a US$320 million pipeline in Mexico, which is supported
by a twenty-five year contract for its entire capacity with Comisión Federal de
Electridad, Mexicos state-owned electric power company.  The proposed pipeline, known as the
Guadalajara Pipeline, is an approximately 305 km (190 mile) pipeline capable of
transporting 500 MMcf/d of natural gas, and is proposed to extend from a
liquefied natural gas terminal under construction near Manzanillo on Mexicos
Pacific Coast to Guadalajara, the second largest city in Mexico.  Regulatory approvals were received in December 2009
and construction is under way with an expected in-service date of first quarter
2011.  ·June 11, 2009. 
TransCanada reached an agreement with ExxonMobil Corporation to jointly
advance the Alaska Pipeline Project.  A
joint project team is developing the engineering, environmental, aboriginal
relations and commercial work.  ·July 1, 2009. 
TransCanada completed the sale of North Baja Pipeline, LLC (North Baja) to its affiliate, TC PipeLines,
LP.  As part of the transaction,
TransCanada agreed to amend its incentive distribution rights with TC
PipeLines, LP. Under the amendment, TransCanada received additional common
units in exchange for a resetting of its incentive


TRANSCANADA
CORPORATION3   distribution rights at a lower percentage which escalates with
increases in TC PipeLines, LP distributions. 
The aggregate consideration received from the partnership included a
combination of cash and common units totaling approximately US$395
million.  With the close of the
transaction, TransCanadas ownership of the partnership increased to 42.6 per
cent.  TransCanada continued to operate
North Baja following the transfer of ownership. 
The system is a 129 km (80 mile) natural gas pipeline that extends from
southwest Arizona to a point on the California/Mexico border and connects with
a natural gas pipeline system in Mexico. 
TransCanadas ownership in TC PipeLines, LP was subsequently reduced to
38.2 per cent in November 2009 after TC PipeLines, LP completed a public
issuance of common units.  ·August 14, 2009.  TransCanada became the sole owner of the
3,456 km (2,147 mile) Keystone Oil Pipeline project that will transport crude
oil from Alberta to markets in the United States (the Keystone Oil
Pipeline) through the purchase of ConocoPhillips remaining
approximately 20 per cent interest for US$553 million and the assumption of
US$197 million of short-term debt. 
TransCanada also assumed the responsibility for ConocoPhillips share of
the capital investment required to complete the project resulting in an
incremental commitment of approximately US$1.7 billion through the end of 2012.  ·September 28, 2009.  TransCanada began work on the final phase of
the North Central Corridor natural gas pipeline, a 300 km (186 mile) extension
of the northern section of the Alberta System. 
This 160 km Red Earth section is expected to be complete by April 2010.  The 140 km North Star section has been
completed and two 13 Megawatt (MW)
compressor units at the MeikleRiver
compressor station were operational on May 15, 2009 and August 21,
2009, respectively.  ·December 2009. 
A Joint Review Panel of the Canadian government released a report on
environmental and socio-economic factors relating to the Mackenzie Gas Pipeline
Project, a proposed 1,200 km (746 mile) natural gas pipeline to extend from a
point near Inuvik, Northwest Territories to the northern border of Alberta,
where it will connect to the Alberta System. 
The report has been submitted to the NEB as part of the review process
for approval of the project.  A decision
is currently expected by fourth quarter 2010. 
TransCanada continues funding of the Mackenzie Valley Aboriginal
Pipeline Limited Partnership for its participation in the Mackenzie Gas
Pipeline Project.  Regulatory
Matters  ·February 26,
2009.  The NEB approved TransCanadas
application for federal regulation of itsAlberta System, which regulation became effective April 29, 2009. The
Alberta System was previously regulated by the Alberta Utilities Commission (AUC).  Under federal
regulation, TransCanada is able to apply to the NEB for approval to extend the
Alberta System across provincial borders, allowing the Company to provide
service to producers outside of Alberta.  ·March 20, 2009. 
TransCanada Québec & Maritimes Pipeline Inc. (TQM) received the NEBs decision on its cost of capital
application for 2007 and 2008, which requested an 11 per cent return on 40 per
cent deemed common equity.  The NEB set a
6.4 per cent after-tax weighted average cost of capital for each of the two
years, which equates to a 9.85 per cent return on 40 per cent deemed common
equity in 2007 and a 9.75 per cent return on 40 per cent deemed common equity
in 2008.  Prior to the decision, TQM was
subject to the NEB return on equity formula of 8.46 per cent and 8.71 per cent
for 2007 and 2008, respectively, on deemed common equity of 30 per cent.  In June 2009, the NEB approved TQMs
final tolls for 2007 and 2008, which reflected the 6.4 per cent after-tax
weighted average cost of capital.  ·May 2009. 
Portland Natural Gas Transmission System (Portland
System) reached a settlement with its customers on certain
short-term issues contained in its general rate case filed with the FERC in April 2008,
which proposed a rate increase of approximately 6 per cent as well as other
changes to its tariff.  The partial
settlement was filed with the FERC for approval and a decision is expected in
2010.  The remaining issues were
litigated and the initial decision from the administrative law judge was issued
in December 2009.  Participants in
the rate case have an opportunity to respond to the initial decision.  The FERC is expected to issue its final
decision on the litigated portion of the rate case in fourth quarter 2010.  ·September 2009.The
NEB held a hearing to review TransCanadas application regarding the Canadian
portion of the planned expansion and extension of the Keystone Oil Pipeline,
which expansion is expected to provide additional capacity in 2013 of 500,000
barrels per day (Bbl/d) from Western Canada to
the United States Gulf Coast, near existing terminals in Port Arthur,
Texas.  The expansion, when completed, is
expected to increase the capacity of the Keystone Oil Pipeline system from 591,000
Bbl/d to approximately 1.1 million Bbl/d. 
The NEB is expected to issue a decision in first quarter 2010.  Permits for the U.S. portion of the expansion
are expected by


TRANSCANADA CORPORATION4   fourth quarter 2010. 
Construction of the expansion facilities is expected to commence in
first quarter 2011 subject to the receipt of the necessary regulatory
approvals.  ·October 8, 2009.  The NEB determined that its RH-2-94 decision
would no longer be in effect.  The
RH-2-94 decision pursuant to the National Energy Board Act
(Canada) established a return on equity formula tied to Government of Canada
bond yields that had formed the basis for determining tolls for certain
pipelines under NEB jurisdiction since January 1, 1995.  The NEB decided that the cost of capital would
be determined by negotiations between pipeline companies and their shippers or
by the NEB if a pipeline company filed a cost of capital application.  The decision affects the calculation of
future tolls for TransCanadas NEB-regulated natural gas pipelines.  In November 2009, the Canadian
Association of Petroleum Producers and the Industrial Gas Users Association
sought leave to appeal the October 2009 NEB decision to the Federal Court
of Appeal and named the NEB as the sole respondent.  In January 2010, TransCanada was granted
respondent status in the matter and in February 2010 filed its submission
opposing the leave application.  ·November 2009. 
The NEB concluded a public hearing process on TransCanadas application
for approval to construct and operate the Groundbirch pipeline, which is
comprised of a 77 km (48 mile) natural gas pipeline and related above ground
facilities.  TransCanada has entered into
firm transportation agreements with Groundbirch customers that are expected to
increase to 1.1 Bcf/d by 2014.  The
Groundbirch pipeline, if approved, would be an extension of the Alberta System
and would connect natural gas supply primarily from the Montney shale gas
formation in northeast British Columbia to existing infrastructure in northwest
Alberta.  Construction of the Groundbirch
pipeline is expected to commence in July 2010 with completion anticipated
in November 2010.  The NEB is
expected to issue a decision in first quarter 2010.  ·November 2009. 
The FERC initiated an investigation to determine whether rates on the
Great Lakes system, a natural gas pipeline system running from northwestern
Idaho, through Washington and Oregon to the California border (the Great Lakes System) are just and reasonable.  In response, Great Lakes filed a cost and
revenue study with the FERC on February 4, 2010.  A hearing is scheduled to commence on August 2,
2010, and an initial decision is required in November 2010.  The impact of the investigation on the Great
Lakes Systems rates and revenues is unknown at this time.  ·November 27, 2009.  TransCanada filed a combined application with
the NEB for approvals of both a new Alberta System Rate Design Settlement, and
the integration of Canadian Utilities
Limited (ATCO Pipelines). 
The rate design was negotiated with all key stakeholders and addresses
the evolving nature of the Alberta System and the integration of ATCO Pipelines.  It also incorporates a single delivery
service for all delivery points resulting from the amalgamation of current
intra-Alberta and export delivery services. 
TransCanada reached a proposed
agreement with ATCO Pipelines to provide integrated natural gas transmission
service to customers on September 8, 2008. 
If approved by the regulatory authorities, the two companies will
combine physical assets under a single rates and services structure with a
single commercial interface with customers but with each company separately
managing assets within distinct operating territories in the province.  TransCanada and ATCO Pipelines continue to
work towards obtaining the necessary regulatory approvals to provide integrated
service to shippers on the Alberta System and the ATCO Pipelines system. The
integration of the Alberta System and ATCO Pipelines system will create the
effect of a single integrated natural gas transmission system in Alberta
resulting in a more efficient delivery of service to customers.  ·December 2009. 
The NEB approved TransCanadas application for 2010 final tolls for its
Canadian gas pipeline system (the Canadian Mainline)
transportation service, effective January 1, 2010.  The 2010 calculated ROE for the Canadian
Mainline will be 8.52 per cent, a decrease from 8.57 per cent in 2009.  The Canadian Mainline will continue to base
its return on the NEBs return on equity formula for 2010 and 2011 in
accordance with the terms of the current Canadian Mainline tolls
settlement.  Reduced throughput and
greater use of shorter distance transportation contracts has resulted in an
increase in Canadian Mainline tolls for 2010 compared to 2009.  This situation, coupled with the ongoing
development and growth of competitive alternative natural gas supply and
infrastructure from the United States shale gas regions, is increasing
competitive pressures on the Canadian Mainline. 
As a result TransCanada indicated that it will develop solutions,
involving possible changes to business model, rate design, and services that
would be designed to increase throughput and revenue in order to reduce
tolls.  TransCanada is also pursuing the
connection of new sources of U.S. gas supply to the existing Canadian Mainline
infrastructure to maintain its existing markets and competitive position.  ·December 2009. 
The FERC issued a Final Environmental Impact Statement (FEIS)for the Bison
Pipeline Project (Bison), a proposed
487 km (303 mile) pipeline from the Powder River Basin in Wyoming to the
Northern Border Pipeline system in Morton County, North Dakota.

review of the end of life estimates for Units 3 and 4.  As a result of the review, Unit 3 was
expected to be in commercial service until 2011, providing an additional two
years of generation before refurbishment. 
After the refurbishment, the end of life estimate for Unit 3 was to be
extended to 2038.  The review also showed
that Unit 4 was expected to remain in commercial service until 2016, providing
seven years of generation before refurbishment, after which the end of life
estimate for Unit 4 was expected to be extended to 2042.  Regulatory Matters  ·January 11, 2008. The FERC issued its FEIS for
Broadwater. The FEIS confirmed project need, supported the location of the
project with acknowledgement of its target market and delivery goals, and found
safety and security risks to be limited and acceptable.  The FEIS concluded that with adherence to
federal and state permit requirements and regulations, Broadwaters proposed
mitigation measures and the FERCs recommendations, the project would not
result in a significant impact on the environment.  ·March 24, 2008. 
FERC authorized the construction and operation of Broadwater, subject to

areas of significant risk to the organizations HS&E business activities.
Management is informed regularly of all important HS&E operational issues
and initiatives through formal reporting processes.  TransCanadas HS&E management system and
performance are assessed by an independent outside firm every three years.  The most recent assessment occurred in December 2009  and did not identify any material issues.  The HS&E management system also is
subject to ongoing internal review to ensure that it remains effective as
circumstances change.  In 2009, employee and
contractor health and safety performance continued to be a top priority.
TransCanadas objective is a health and safety performance consistent with top
quartile companies in its sectors. 
Overall, TransCanadas safety frequency rates in 2009 continued to be
better than most industry benchmarks.  The safety and integrity of TransCanadas
existing and newly developed energy infrastructure also continued to be top
priorities.  All new assets are designed,
constructed and commissioned with full consideration given to safety and
integrity, and are not brought into service until all necessary requirements
are satisfied. The Company expects to spend approximately $181 million in 2010
for pipeline integrity on its wholly owned pipelines, which is $10 million
higher than in 2009 primarily due to increased levels of in-line pipeline
inspection on all systems. Under the approved regulatory models in Canada,
pipeline integrity expenditures on NEB regulated pipelines are treated on a
flow-through basis and, as a result, have no impact on TransCanadas
earnings.  Under the Keystone Oil
Pipeline contracts, pipeline integrity expenditures are recovered through the
tolling mechanism and, as a result, have no impact on TransCanadas
earnings.  Expenditures for the GTN
System may also be recovered through a cost recovery mechanism in its rates.
TransCanadas pipeline safety record in 2009 continued to be above industry
benchmarks. TransCanada experienced three pipeline breaks in 2009. The first
occurred in a


TRANSCANADA CORPORATION     17   remote part of northern Alberta. The other
two occurred in rural parts of northern Ontario. The breaks resulted in minimal
impact with no injuries and only minor property damage in one of the incidents.
All three incidents were subject to a Level 3 investigation by the
Transportation Safety Board of Canada. Spending associated with public safety
on the Energy assets is focused primarily on TransCanadas hydro dams and
associated equipment, and is consistent with previous years.  Environmental
Protection  TransCanadas facilities are subject to
various federal, provincial, state and local statutes and regulations regarding
environmental quality and pollution control. 
TransCanada has ongoing inspection programs designed to keep all of its
facilities in compliance with environmental requirements and TransCanada is
confident that its systems are in material compliance with the applicable
requirements.  In 2009, TransCanada conducted environmental
risk assessments and remediation work, as well as various retirement,
reclamation and restoration activities on its Canadian and U.S. facilities. At December 31,
2009, TransCanada had recorded liabilities of approximately $91 million (2008 -
$86 million) for remediation obligations and compliance costs associated with
greenhouse gas (GHG) legislation, including
contingencies. The Company believes it has considered all necessary
contingencies and established appropriate reserves for environmental
liabilities, however, there is the risk that unforeseen matters may arise
requiring the Company to set aside additional amounts.  TransCanada is not aware of any material
outstanding orders, claims or lawsuits against the Company in relation to the
release or discharge of any material into the environment or in connection with
environmental protection.  North American climate change policy continues to evolve at regional
and national levels. In 2009, TransCanada owned assets in three Canadian
provinces where regulations exist to address industrial GHG emissions.
TransCanada has put in place procedures to address these regulations.  In Alberta, under the Specified Gas Emitters Regulation, industrial
facilities are required to reduce GHG emissions intensities by 12 per cent
effective July 2007. TransCanadas Alberta-based facilities are subject to
this regulation, as are the Sundance and Sheerness coal-fired power facilities
with which TransCanada has power purchase agreements. As an alternative to
reducing emissions intensities, compliance can be achieved through the
retirement of offsets or payments to a technology fund at a cost of $15 per
tonne of carbon dioxide (CO2) emissions
in excess of the mandated reduction. A program is in place to manage the
compliance costs incurred by these assets as a result of regulation. Compliance
costs on the Alberta System are recovered through tolls paid by customers.
Recovery of compliance costs at TransCanadas power generation facilities in
Alberta is dependent ultimately on market prices for electricity. TransCanada
has estimated and recorded costs of $17 million for 2009.  These costs will be finalized when compliance
reports are submitted in March 2010.  The hydrocarbon royalty in Québec is collected by the natural gas
distributor on behalf of the Québec government through a green fund
contribution charge on gas consumed. In 2009, the cost pertaining to the
Bécancour facility arising from the hydrocarbon royalty was less than $1
million as a result of an agreement between TransCanada and Hydro-Québec to
temporarily suspend the facilitys power generation. The cost is expected to
increase substantially when the plant returns to service.  British Columbias carbon tax, which came into effect in mid-2008,
applies to CO2 emissions arising from fossil fuel combustion. Compliance costs
for fuel combustion at the Companys compressor and meter stations in British
Columbia are recovered through tolls paid by customers. Costs related to the
carbon tax in 2009 were $3 million.  The
cost per tonne of CO2 was $15 in 2009 and will increase to $20 per tonne and
$25 per tonne in 2010 and 2011, respectively.  Northeastern U.S. states
that are members of the Regional Greenhouse Gas Initiative (RGGI) implemented a CO2 cap and trade program for
electricity generators effective January 1, 2009. Under the RGGI, both the
Ravenswood and Ocean State Power generation facilities will be required to
submit allowances by December 31, 2011. TransCanada participated in the
quarterly auctions of allowances for the Ravenswood and Ocean State power
generation facilities and incurred related costs of $8 million in 2009.  These costs were generally recovered through
the power market and the net impact on TransCanada was not significant.


TRANSCANADA CORPORATION     18   RISK FACTORS  Environmental
Risk Factors  Environmental risks from TransCanadas operating
facilities typically include: air emissions, such as nitrogen oxides,
particulate matter and greenhouse gases; potential impacts on land, including
land reclamation or restoration following construction; the use, storage or
release of chemicals or hydrocarbons; the generation, handling and disposal of
wastes and hazardous wastes; and water impacts such as uncontrolled water
discharge. Environmental controls including physical design, programs,
procedures and processes are in place to effectively manage these risks and
TransCanada believes it has considered all necessary contingencies and
established appropriate reserves for environmental liabilities.  However, there is the risk that unforeseen
matters may arise requiring TransCanada to set aside additional monies.  As
mentioned above, TransCanadas operations are subject to various environmental
laws and regulations that establish compliance and remediation obligations.
Compliance obligations can result in significant costs associated with
installing and maintaining pollution controls, fines and penalties resulting
from any failure to comply, and potential limitations on operations.
Remediation obligations can result in significant costs associated with the
investigation and remediation of contaminated properties, some of which have
been designated as Superfund sites by the United States Environmental
Protection Agency under the Comprehensive
Environmental Response, Compensation and Liability Act, and with
damage claims arising out of the contamination of properties. It is not
possible for TransCanada to estimate the amount and timing of all future
expenditures related to environmental matters due to:  ·
  uncertainties in estimating pollution control and clean up costs,
  including at sites where only preliminary site investigation or agreements
  have been completed;·
  the potential discovery of new sites or additional information at
  existing sites;·
  the uncertainty in quantifying liability under environmental laws
  that impose joint and several liability on all potentially responsible
  parties;·
  the evolving nature of environmental laws and regulations, including
  the interpretation and enforcement thereof; and·
  the potential for litigation on existing or discontinued assets.  In addition to those climate change policies
already in force and which are described above under the heading Environmental
Protection, there are also several federal (Canada and U.S.), regional and
provincial initiatives currently in development.  While recent political and economic events may
significantly affect the scope and timing of new measures that are put in
place, TransCanada anticipates that most of the Companys facilities in Canada
and the United States are or will be captured under federal and/or regional
climate change regulations to manage industrial GHG emissions.  Certain 
initiatives are outlined below.  The
Canadian government has continued to express interest in pursuing a harmonized
continental climate change strategy. In January 2010, Environment Canada
listed a revised target to the United Nations Framework Convention on Climate
Change as part of its submission for the Copenhagen Accord. The submitted
target represents a 17 per cent GHG emissions reduction by 2020 relative to
2005 levels. The submission states that Canada will align with the final
economy-wide emissions targets of the United States in enacted
legislation.  TransCanada expects that
pipeline and power generation facility emissions will be subject to the
reduction targets for industrial emitters.  Climate
change is a strategic issue for the United States government and federal policy
to manage domestic GHG emissions continues to be a priority. The Environmental
Protection Agency has released an endangerment finding regarding GHG emissions
under the Clean Air Act. This finding was to
determine whether the six types of GHGs in the atmosphere threaten the health
and welfare of current and future generations. 
The United States House passed a climate bill in June and the
Senate is deliberating on a series of climate bills.  At a regional level,TransCanada has
assets located in provinces where members of the Western Climate Initiative (WCI) have drafted regulations that apply to industrial GHG
emitters. The Canadian WCI members include B.C., Manitoba, Ontario and Québec.
The draft climate change strategies are expected to come into effect in 2012
and are expected to affect TransCanadas pipeline and power facilities. The
details of how these provincial programs will align with the Canadian
governments climate change policies remain uncertain.  Seven
western U.S. states, along with the four Canadian provinces discussed above,
are focused on the implementation of a cap and trade program under the WCI. Members
of the WCI have set a GHG emission target of 15 per cent below 2005


TRANSCANADA
CORPORATION     19   levels
by 2020. California, a WCI founding member, has released draft cap and trade
regulations that, if enacted, are anticipated to have an impact on the Companys
pipeline assets in the state. The financial implications are not expected to be
material. Under the current form of draft regulations in Washington and Oregon
it is expected that there will not be a significant cost of compliance in these
states. TransCanada will continue to monitor these developments.  Participants
in the Midwestern Greenhouse Gas Reduction Accord, which involves six U.S.
states and the province of Manitoba, are developing a regional strategy for
reducing members GHG emissions that will include a multi-sector cap and trade
mechanism. Draft recommendations have been released but as yet not formally
endorsed by participant states and Manitoba.  TransCanada
monitors climate change policy developments and, when warranted, participates
in policy discussions in jurisdictions where the Company has operations. The
Company is also continuing its programs to manage GHG emissions from its
facilities and to evaluate new processes and technologies that result in
improved efficiencies and lower GHG emission rates.  Other Risk Factors  A discussion of the Companys
risk factors can be found in the MD&A under the headings Pipelines -
Opportunities and Developments, Pipelines - Business Risks, Pipelines 
Outlook, Energy - Opportunities and Developments, Energy - Business Risks,
Energy  Outlook and Risk Management and Financial Instruments.  DIVIDENDS  The Board has not adopted a formal dividend
policy. The Board reviews the financial performance of TransCanada quarterly
and makes a determination of the appropriate level of dividends to be declared
in the following quarter. Currently, TransCanadas payment of dividends is
primarily funded from dividends TransCanada receives as the sole common
shareholder of TCPL. Provisions of various trust indentures and credit
arrangements to which TCPL is a party restrict TCPLs ability to declare and
pay dividends to TransCanada under certain circumstances and, if such
restrictions apply, they may, in turn, have an impact on TransCanadas ability
to declare and pay dividends. In the opinion of TransCanadas management, such
provisions do not currently restrict or alter TransCanadas ability to declare
or pay dividends.  Holders of Series 1
Preferred Shares are entitled to receive fixed cumulative preferential
dividends, at an annual rate of $1.15 per share, payable quarterly, as and when
declared by the Board, for the initial five-year period ending December 31,
2014.  For the period from issuance on September 30,
2009 to December 31, 2009, dividends in the amount of $0.2899 per share
were declared and paid on the Series 1 Preferred Shares.  The dividend rate on the Series 1
Preferred Shares will reset on December 31, 2014 and every five years
thereafter at a rate equal to the sum of the then five-year Government of
Canada bond yield and 1.92%.   The
holders of Series 1 Preferred Shares have the right to convert their
shares into cumulative redeemable first preferred shares, series 2 (the Series 2 Preferred Shares) as set out under First
Preferred Shares below.  The dividends declared per Common Share of
TransCanada during the past three completed financial years are set forth in
the following table:  2009

  $1.36  DESCRIPTION OF CAPITAL STRUCTURE  Share
Capital  TransCanadas authorized
share capital consists of an unlimited number of Common Shares, of which
684,358,621 were issued and outstanding at Year End, and an unlimited number of
first preferred shares and second preferred shares, issuable in series, of
which 22,000,000 Series 1 Preferred Shares are issued and outstanding. The
following is a description of the material characteristics of each of these
classes of shares.


TRANSCANADA CORPORATION     20   Common Shares The Common Shares entitle
the holders thereof to one vote per share at all meetings of shareholders,
except meetings at which only holders of another specified class of shares are
entitled to vote, and, subject to the rights, privileges, restrictions and
conditions attaching to the first preferred shares and the second preferred
shares, whether as a class or a series, and to any other class or series of
shares of TransCanada which rank prior to the Common Shares, entitle the
holders thereof to receive (i) dividends if, as and when declared by the
Board out of the assets of TransCanada properly applicable to the payment of
the dividends in such amount and payable at such times and at such place or
places as the Board may from time to time determine and (ii) the remaining
property of TransCanada upon a dissolution.  TransCanada has a Shareholder Rights Plan
(the Plan) that is designed to ensure, to
the extent possible, that all shareholders of TransCanada are treated fairly in
connection with any take-over bid for the Company.  The Plan creates a right attaching to each
Common Share outstanding and to each Common Share subsequently issued.  Each right becomes exercisable ten trading
days after a person has acquired, or commences a take-over bid to acquire, 20
per cent or more of the Common Shares, other than by an acquisition pursuant to
a take-over bid permitted under the terms of the Plan.  Prior to a flip-in event (as described
below), each right permits registered holders to purchase from the Company
Common Shares of TransCanada at the exercise price equal to three times the
market price of such shares, subject to adjustments and anti-dilution
provisions (the Exercise Price).  The beneficial acquisition by any person of
20 percent or more of the Common Shares, other than by way of a take-over bid
permitted under the terms of the Plan, is referred to as a Flip-in Event.  Ten trading days after a Flip-in Event, each
TransCanada right will permit registered holders to receive, upon payment of
the exercise price, the number of Common Shares with an aggregate market price
equal to twice the Exercise Price.  The
Plan was reconfirmed at the 2007 annual and special meeting of shareholders and
must be reconfirmed every third annual meeting thereafter.  TransCanada has a Dividend Reinvestment and
Share Purchase Plan which permits common and preferred shareholders of
TransCanada to elect to reinvest their cash dividends in additional Common
Shares of TransCanada, and preferred shareholders of TCPL to elect, until such
time as their participation is no longer permitted under securities law, to
reinvest their cash dividends in Common Shares of TransCanada.  These Common Shares may be provided to the
participants at a discount to the average market price in the five days before
dividend payment.  The discount was set
at two per cent commencing with the dividend payable in April 2007 and was
increased to three per cent commencing with the dividend payable in January 2009.  Participants may also make additional cash
payments of up to $10,000 per quarter to purchase additional Common Shares,
which optional purchases are not eligible for any discount on the price of
Common Shares. Participants are not responsible for payment of brokerage
commissions or other transaction expenses for purchases made pursuant to the
Dividend Reinvestment and Share Purchase Plan.  TransCanada also has stock-based compensation
plans that allow some employees to purchase Common Shares of TransCanada.  Option exercise prices approximate the market
price for the Common Shares on the date the options were issued.  Options granted under the plan are generally
fully exercisable after three years and expire seven years after the date of
grant.  First Preferred Shares Subject to certain limitations, the Board
may, from time to time, issue first preferred shares in one or more series and
determine for any such series, its designation, number of shares and respective
rights, privileges, restrictions and conditions. The first preferred shares as
a class have, among others, provisions to the following effect.  The first preferred shares of each series
rank on a parity with the first preferred shares of every other series, and are
entitled to preference over the Common Shares, the second preferred shares and
any other shares ranking junior to the first preferred shares with respect to
the payment of dividends, the repayment of capital and the distribution of
assets of TransCanada in the event of a liquidation, dissolution or winding up
of TransCanada.  Except as provided by the Canada Business Corporations Act or as
referred to below, the holders of the first preferred shares will not have any
voting rights nor will they be entitled to receive notice of or to attend
shareholders meetings. The holders of any particular series of first preferred
shares will, if the directors so determine prior to the issuance of such
series, be entitled to such voting rights as may be determined by the directors
if TransCanada fails to pay dividends on that series of preferred shares for
any period as may be so determined by the directors.  The provisions attaching to the first
preferred shares as a class may be modified, amended or varied only with the
approval of the holders of the first preferred shares as a class. Any such
approval to be given by the holders of the first preferred shares may be given
by the affirmative vote of the holders of not less than 662¤3per cent of the first preferred shares
represented and voted at a meeting or adjourned meeting of such holders.


TRANSCANADA CORPORATION     21   The Series 1 Preferred Shares are
entitled to the payment of dividends as set out above under Dividends.  The Series 1 Preferred Shares are
redeemable by TransCanada in whole or in part on or after December 31,
2014, by the payment of an amount in cash for each share to be redeemed equal
to $25.00 plus all accrued and unpaid dividends thereon.  The holders of Series 1 Preferred Shares
have the right to convert their shares into cumulative redeemable first
preferred shares, series 2 (the Series 2 Preferred
Shares), subject to certain conditions, on December 31, 2014
and on December 31 of every fifth year thereafter.  The holders of Series 2 Preferred Shares
will be entitled to receive quarterly floating rate cumulative dividends, as
and when declared by the Board, at a rate equal to the sum of the then 90-day
Government of Canada treasury bill rate plus 1.92%.  In the event of liquidation, dissolution or
winding up of TransCanada, the holders of Series 1 Preferred Shares shall
be entitled to receive $25.00 per Series 1 Preferred Share plus all
accrued and unpaid dividends thereon in preference over the Common Shares or
any other shares ranking junior to the Series 1 Preferred Shares.  Except as provided by the Canada Business Corporations Act, the
holders of Series 1 Preferred Shares are not entitled to receive notice
of, attend at, or vote at any meeting of shareholders unless and until TransCanada
shall have failed to pay eight quarterly dividends, whether or not consecutive,
in which case holders of Series 1 Preferred Shares shall have the right to
receive notice of an to attend each meeting of shareholders at which directors
are to be elected and which take place more than 60 days after the date on
which the failure first occurs, and to one vote with respect to resolutions to
elect directors for each Series 1 Preferred Share until all arrears of
dividends have been paid.  Second Preferred Shares The rights, privileges,
restrictions and conditions attaching to the second preferred shares are
substantially identical to those attaching to the first preferred shares,
except that the second preferred shares are junior to the first preferred shares
with respect to the payment of dividends, repayment of capital and the
distribution of assets of TransCanada in the event of a liquidation,
dissolution or winding up of TransCanada.  CREDIT RATINGS  Although TransCanada has not
issued debt to the public, it has been assigned credit ratings by Moodys
Investors Service, Inc. (Moodys) and
Standard and Poors (S&P).  Moodys has assigned an issuer rating of Baa1
with a stable outlook and S&P has assigned a long-term corporate credit
rating of A- with a stable outlook.  In
third quarter 2009, TransCanada completed the issuance of $550 million of Series 1
Preferred Shares, which were assigned ratings by DBRS Limited (DBRS) and S&P of Pfd-2 (low) and P-2,
respectively.  TransCanada does not
presently intend to issue debt securities to the public in its own name and any
future debt financing requirements are expected to continue to be funded
primarily through its subsidiary, TCPL. The following table sets out the
current credit ratings assigned to those outstanding classes of securities of
TCPL which have been rated by DBRS, Moodys and S&P:  DBRS

  Stable   Credit ratings are intended to provide
investors with an independent measure of credit quality of an issue of
securities. Credit ratings are not recommendations to purchase, hold or sell
securities and do not address the market price or suitability of a specific
security for a particular investor. There is no assurance that any rating will
remain in effect for any given period of time or that any rating will not be
revised or withdrawn entirely by a rating agency in the future if, in its
judgment, circumstances so warrant. A description of the rating agencies
credit ratings listed in the table above is set out below.  DBRS Limited (DBRS)  DBRS has different rating scales for short
and long-term debt and preferred shares. High or low grades are used to
indicate the relative standing within a rating category. The absence of either
a high or low designation indicates the rating is in the middle of the
category. The R-1 (low) rating assigned to TCPLs short-term debt is in the
third highest of ten rating categories and indicates satisfactory credit
quality. The overall strength and outlook for key liquidity, debt and
profitability ratios are still respectable. Any qualifying negative factors
that exist are considered manageable, and the entity is normally of sufficient
size to have some influence in its industry. The A rating assigned to TCPLs
senior unsecured debt is in the third highest of ten


TRANSCANADA
CORPORATION     22   categories for long-term debt. Long-term debt
rated A is of satisfactory credit quality. Protection of interest and principal
is still substantial, but the degree of strength is less than that of AA rated
securities. While a respectable rating, entities in the A category are
considered to be more susceptible to adverse economic conditions and have
greater cyclical tendencies than higher rated entities.  The BBB (high) rating assigned to junior
subordinated notes is in the fourth highest of the ten categories for long-term
debt.  Long-term debt rated BBB is of
adequate credit quality.  Protection of
interest and principal is considered acceptable but there may be other adverse
conditions present which reduce the strength of the entity and its rated
securities. The Pfd-2 (low) rating assigned to TCPLs and TransCanadas
preferred shares is in the second highest of six rating categories for
preferred shares. Preferred shares rated Pfd-2 are of satisfactory credit
quality. Protection of dividends and principal is still substantial; however,
earnings, the balance sheet and coverage ratios are not as strong as Pfd-1
rated companies.  Moodys Investors Service, Inc. (Moodys)  Moodys has different rating scales for short
and long-term obligations. Numerical modifiers 1, 2 and 3 are applied to each
rating classification, with 1 being the highest and 3 being the lowest. The A3
rating assigned to TCPLs senior unsecured debt is in the third highest of nine
rating categories for long-term obligations. Obligations rated A are considered
upper medium grade and are subject to low credit risk. The Baa1 and Baa2
ratings assigned to TCPLs junior subordinated debt and preferred shares,
respectively, are in the fourth highest of nine rating categories for long-term
obligations, with the junior subordinated debt ranking slightly higher within
the Baa rating category with a modifier of 1 as opposed to the modifier of 2 on
the preferred shares. Obligations rated Baa are subject to moderate credit
risk, are considered medium-grade, and as such, may possess certain speculative
characteristics.  Standard &
Poors (S&P)  S&P has different rating scales for
short- and long-term obligations. Ratings may be modified by the addition of a
plus (+) or minus (-) sign to show the relative standing within a particular
rating category. The A- rating assigned to TCPLs senior unsecured debt is in
the third highest of ten rating categories for long-term obligations. An A
rating indicates the obligors capacity to meet its financial commitment is
strong; however, the obligation is slightly more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rated categories. The BBB  and
P-2  ratings assigned to TCPLs junior
subordinated notes and TCPLs and TransCanadas preferred shares exhibits
adequate protection parameters. However, adverse economic conditions or
changing circumstances are more likely to lead to a weakened capacity of the
obligor to meet its financial commitment on the obligation.  MARKET FOR SECURITIES  TransCanadas Common Shares

  Prior to June 2006, Assistant Controller  Conflicts of Interest  Directors and officers of
TransCanada and its subsidiaries are required to disclose the existence of
existing or potential conflicts in accordance with TransCanada policies
governing directors and officers and in accordance with the Canada Business Corporations Act. Although
some of the directors sit on boards or may be otherwise associated with companies
that ship natural gas on TransCanadas pipeline systems, TransCanada, as a
common carrier in Canada, cannot, under its tariff, deny transportation service
to a credit-worthy shipper. Further, due to the specialized nature of the
industry, TransCanada believes that it is important for its Board to be
composed of qualified and knowledgeable directors, so some of them must come
from the oil and gas producer and shipper community; the Governance Committee
monitors relationships among directors to ensure that business associations do
not affect the Boards performance. In a circumstance where a director declares
an interest in any material contract or material transaction being considered
at a meeting, the director generally absents himself or herself from the
meeting during the consideration of the matter, and does not vote on
the matter.  CORPORATE
GOVERNANCE  The Board and the members of TransCanadas
management are committed to the highest standards of corporate governance.
TransCanadas corporate governance practices comply with the governance rules of
the Canadian Securities Administrators (CSA),
those of the NYSE and of the SEC
applicable to foreign issuers, and those mandated by the U.S. Sarbanes-Oxley Act of 2002. As a
non-U.S. company, TransCanada is not required to comply with most of the
NYSE corporate governance listing standards; however, except as summarized on
our website at www.transcanada.com, the governance practices followed are
in compliance with the NYSE standards for U.S. companies in all
significant respects. TransCanada is in compliance with the CSAs National
Instrument 52-110 pertaining to audit committees; National
Policy 58-201, Corporate Governance Guidelines; and National
Instrument 58-101, Disclosure of Corporate Governance Practices. Further
information about TransCanadas corporate governance can be found on
TransCanadas website at www.transcanada.com under the heading Corporate
Governance or at Schedule A to TransCanadas management proxy circular.  AUDIT COMMITTEE  TransCanada has an Audit
Committee which is responsible for assisting the Board in overseeing the
integrity of TransCanadas financial statements and compliance with legal and
regulatory requirements and in ensuring the independence and performance of
TransCanadas internal and external auditors. 
The Charter of the Audit Committee can be found in Schedule C of
this AIF and on TransCanadas website under the Corporate Governance - Board
Committees page, at www.transcanada.com.  Relevant Education and Experience of Members  The members of the Audit
Committee at Year End were Kevin E. Benson (Chair), Derek H. Burney, E. Linn
Draper, Paul L. Joskow, John A. MacNaughton and D. Michael G. Stewart.  The Board believes that the composition of
the Audit Committee reflects a high level of financial literacy and expertise.
Each member of the Audit Committee has been determined by the Board to be independent
and financially literate within the meaning of the definitions under Canadian
and U.S. securities laws and the NYSE rules. In addition, the Board has
determined that Mr. Benson is an Audit Committee Financial Expert as
that term is defined under U.S. securities laws. The Board has made these
determinations based on the education and breadth and depth of experience of
each member of the Audit Committee. The following is a description of the
education and experience, apart from their respective roles as directors of
TransCanada, of

Policies and Procedures  TransCanadas Audit Committee has adopted a
pre-approval policy with respect to permitted non-audit services. Under the
policy, the Audit Committee has granted pre-approval for specified non-audit
services. For engagements of $25,000 or less which are not within the annual
pre-approved limit, approval by the Audit Committee is not required, and for
engagements between $25,000 and $100,000, approval of the Audit Committee Chair
is required, and the Audit Committee is to be informed of the engagement at the
next scheduled Audit Committee meeting. For all engagements of $100,000 or
more, pre-approval of the Audit Committee is required. In all cases, regardless
of the dollar amount involved, where there is a potential for conflict of
interest involving the external auditor to arise on an engagement, the Audit
Committee Chair must pre-approve the assignment.


TRANSCANADA
CORPORATION   28   To date, TransCanada has not approved any
non-audit services on the basis of the de-minimus exemptions. All non-audit
services have been pre-approved by the Audit Committee in accordance with the

Function  While the Audit
Committee has the responsibilities and powers set forth in this Charter, it is
not the duty of the Audit Committee to plan or conduct audits or to determine
that the Companys financial statements and disclosures are complete and
accurate or are in accordance with generally accepted accounting principles and
applicable rules and regulations. 
These are the responsibilities of management and the external
auditors.  The Audit Committee, its Chair
and any of its members who have accounting or related financial management
experience or expertise, are members of the Board, appointed to the Audit
Committee to provide broad oversight of the financial disclosure, financial
risk and control related activities of the Company, and are specifically not
accountable nor responsible for the day to day operation of such
activities.  Although designation of a
member or members as an audit committee financial expert is based on that
individuals education and experience, which that individual will bring to bear
in carrying out his or her duties on the Audit Committee, designation as an audit
committee financial expert does not impose on such person any duties,
obligations or liability that are greater than the duties, obligations and
liability imposed on such person as a member of the Audit Committee and Board
in the absence of such designation. 
Rather, the role of any audit committee financial expert, like the role
of all Audit Committee members, is to oversee the process and not to certify or
guarantee the internal or external audit of the Companys financial information
or public disclosure.  3.Composition
of Audit Committee  The Audit
Committee shall consist of three or more Directors, a majority of whom are
resident Canadians (as defined in the Canada Business Corporations Act), and
all of whom are unrelated and/or independent for the purposes of applicable
Canadian and United States securities law and applicable rules of any
stock exchange on which the Companys shares are listed.  Each member of the Audit Committee shall be
financially literate and at least one member shall have accounting or related
financial management expertise (as those terms are defined from time to time
under the requirements or guidelines for audit committee service under
securities laws and the applicable rules of any stock exchange on which
the Companys securities are listed for trading or, if it is not so defined as
that term is interpreted by the Board in its business judgment).


TRANSCANADA CORPORATIONB-6   4.Appointment
of Audit Committee Members  The members of the
Audit Committee shall be appointed by the Board from time to time, on the
recommendation of the Governance Committee and shall hold office until the next
annual meeting of shareholders or until their successors are earlier appointed
or until they cease to be Directors of the Company.  5.Vacancies  Where a vacancy
occurs at any time in the membership of the Audit Committee, it may be filled
by the Board on the recommendation of the Governance Committee.  6.Audit
Committee Chair  The Board shall appoint a Chair of the Audit Committee who
shall:  (a)review and approve the agenda for each meeting of the
Audit Committee and as appropriate, consult with members of management;  (b)preside over meetings of the Audit Committee;  (c)make suggestions and provide feedback from the Audit Committee
to management regarding information that is or should be provided to the Audit
Committee;  (d)report to the Board on the activities of the Audit
Committee relative to its recommendations, resolutions, actions and concerns;
and  (e)meet as necessary with the internal and external
auditors.  7.Absence
of Audit Committee Chair  If the Chair of
the Audit Committee is not present at any meeting of the Audit Committee, one
of the other members of the Audit Committee present at the meeting shall be chosen
by the Audit Committee to preside at the meeting.  8.Secretary
of Audit Committee  The Corporate Secretary
shall act as Secretary to the Audit Committee.  9.Meetings  The Chair, or any
two members of the Audit Committee, or the internal auditor, or the external
auditors, may call a meeting of the Audit Committee.  The Audit Committee shall meet at least
quarterly.  The Audit Committee shall
meet periodically with management, the internal auditors and the external
auditors in separate executive sessions.  10.Quorum  A majority of the
members of the Audit Committee, present in person or by telephone or other
telecommunication device that permit all persons participating in the meeting
to speak to each other, shall constitute a quorum.  11.Notice of Meetings  Notice of the time
and place of every meeting shall be given in writing or facsimile communication
to each member of the Audit Committee at least 24 hours prior to the time fixed
for such meeting; provided, however, that a member may in any manner waive a
notice of a meeting.  Attendance of a
member at a meeting is a waiver of notice of the meeting, except where a member
attends a meeting for the express purpose of objecting to the transaction of
any business on the grounds that the meeting is not lawfully called.  12.Attendance of Company Officers
and Employees at Meeting  At the invitation
of the Chair of the Audit Committee, one or more officers or employees of the
Company may attend any meeting of the Audit Committee.


TRANSCANADA
CORPORATIONB-7   13.Procedure, Records and Reporting  The Audit
Committee shall fix its own procedure at meetings, keep records of its
proceedings and report to the Board when the Audit Committee may deem appropriate
but not later than the next meeting of the Board.  14.Review of Charter and Evaluation
of Audit Committee  The Audit
Committee shall review its Charter annually or otherwise, as it deems
appropriate, and if necessary propose changes to the Governance Committee and
the Board.  The Audit Committee shall
annually review the Audit Committees own performance.  15.Outside Experts and Advisors  The Audit
Committee is authorized, when deemed necessary or desirable, to retain and set
and pay the compensation for independent counsel, outside experts and other
advisors, at the Companys expense, to advise the Audit Committee or its
members independently on any matter.  16.Reliance  Absent actual
knowledge to the contrary (which shall be promptly reported to the Board), each
member of the Audit Committee shall be entitled to rely on (i) the
integrity of those persons or organizations within and outside the Company from
which it receives information, (ii) the accuracy of the financial and
other information provided to the Audit Committee by such persons or
organizations and (iii) representations made by Management and the
external auditors, as to any information technology, internal audit and other
non-audit services provided by the external auditors to the Company and its
subsidiaries.

our competitive
  position Over $40 Billion in Assets With more than $40 billion in assets,
  TransCanada is a leader in the responsible development and reliable operation
  of North American energy infrastructure including natural gas and crude oil
  pipelines, power generation and natural gas storage facilities. North
  Americas Largest Natural Gas Pipeline Network TransCanadas 60,000 kilometre
  (37,000 mile) wholly owned natural gas pipeline network delivers
  approximately 20 percent of the natural gas consumed in North America each
  day. Our system taps into virtually every major natural gas supply basin on
  the continent and provides our customers with unparalleled access to premium
  markets. Looking forward, our vast pipeline network is well positioned to
  connect new sources of supply such as shale gas and northern gas to growing
  North American markets. North Americas Second Largest Natural Gas Storage
  Operator With approximately 380 billion cubic feet (Bcf) of storage capacity,
  we are one of the continents largest providers of natural gas storage and
  related services. Collectively, our storage facilities are capable of meeting
  the needs of nearly four million homes each year. Canadas Largest Private
  Sector Power Generator TransCanada owns, controls or is developing
  approximately 11,700 megawatts of power generation in Canada and the United
  States  enough capacity to power nearly 12 million homes. Our diversified
  power portfolio includes natural gas, nuclear, coal, hydro and wind
  generation primarily located in Alberta, Ontario, Québec and the northeastern
  United States. Premier North American Oil Pipeline Under Construction We are
  developing one of North Americas largest crude oil delivery systems. Once
  completed, the Keystone pipeline system will be capable of moving 1.1 million
  barrels per day (Bbl/d) from Western Canada to North Americas largest
  refining markets in the U.S. Midwest and Gulf Coast. In the future, Keystone
  could be expanded to 1.5 million Bbl/d in response to additional market
  demand. 4,000 Talented Employees Our success is a reflection of our
  exceptional team of over 4,000 committed employees who bring skill,
  experience, energy and knowledge to the work they do. They are our
  competitive advantage.

$22 Billion of
  Projects Commercially Secured TransCanada is in the midst of a $22 billion
  capital program that will see a number of attractive, low-risk projects
  completed and placed into service over the next five years. Projects include
  the Keystone pipeline system, the Alberta Systems North Central Corridor
  project, the Bison pipeline, the Bruce Power Refurbishment and Restart
  Project and the development of three large-scale, natural gas-fired power
  plants. Each project is secured by long-term agreements with strong,
  creditworthy customers. As a result, we expect they will generate significant
  long-term returns for our shareholders. A Strong Financial Position
  TransCanada has invested approximately $10 billion in these large-scale,
  multi-year projects using a combination of internally-generated cash and
  proceeds from recent debt and equity issues. Investing in energy
  infrastructure is a long-cycle, capital intensive business. To be successful
  we must maintain a strong financial position. Our prudent approach to funding
  this unprecedented growth, along with our growing cash flow, provides us with
  financial flexibility going forward. Visible Growth Over the Next Five Years
  Looking to the future, once all these assets are placed into service they are
  expected to generate approximately $2.5 billion of additional earnings before
  interest, taxes, depreciation and amortization (EBITDA) on an annual basis.
  The growth in EBITDA is also expected to lead to significant growth in
  earnings and cash flow per share over the next five years. $60 Billion of
  Projects in Development Over the longer term, we will continue to create
  value for our shareholders and our customers by conceiving, building, owning
  and operating the energy infrastructure that North America needs. Today, we
  have more than $60 billion of projects under development. Potential future
  projects include expansions of our existing pipeline infrastructure, new
  pipeline infrastructure, new natural gas storage facilities and new power
  plants. As we advance these initiatives, we will maintain the same
  disciplined, low-risk approach to creating value for our shareholders. At
  TransCanada we recognize that with growth comes greater responsibility.
  Responsibility to our employees, to our customers, to the contractors who
  work with us, to the regulators who scrutinize our proposals, to the people in
  communities located near our facilities and to the environment. As we invest
  in the future today, TransCanada is committed to being a reliable and safe
  operator that treats all stakeholders with honesty and respect. our
  unparalleled portfolio of growth opportunities

  the system to the U.S. Gulf Coast is expected to be operational early in
  2013, pending regulatory approvals. Keystone will have the capacity to move
  1.1 million Bbl/d when completed. investing in the future 1 Alberta System
  North Central Corridor Expansion The $800 million North Central Corridor
  project is scheduled to be complete by April 2010. This 300 km (186 mile)
  pipeline will provide capacity to ship increasing natural gas supplies in
  northwest Alberta and northeast B.C. while helping to optimize natural gas
  flows on the Alberta System. The pipelines first phase began operating in
  2009. 1 Alberta System Groundbirch and Horn River Projects The Groundbirch
  and Horn River pipeline projects will move shale gas from northeast B.C. to
  North American markets. Shipping agreements on the 77 km (48 mile)
  Groundbirch line amount to 1.1 billion cubic feet per day (Bcf/d) by 2014.
  Customers have committed to 503 million cubic feet per day (mmcf/d) by 2014
  on the Horn River Project. The 72 km (45 mile) Horn River expansion should be
  complete in second quarter 2012, while Groundbirch should be operational late
  in 2010. 10 Bison The 487 km (303 mile) Bison pipeline will extend from the
  Powder River Basin in Wyoming to the Northern Border pipeline system in North
  Dakota. The project, which is expected to cost US$600 million, has shipping
  commitments for 407 mmcf/d. Construction is expected to begin in second
  quarter 2010 following the receipt of the necessary regulatory approvals and
  the pipeline is expected to commence operations in fourth quarter 2010. 15
  Guadalajara In 2009, TransCanada signed a contract to build, own and operate
  the US$320 million Guadalajara pipeline in Mexico. The 305 km (190 mile)
  pipeline will move liquified natural gas (LNG) from Manzanillo to
  Guadalajara, Mexicos second largest city. Construction is underway and the
  pipeline is expected to be placed into service in first quarter 2011. $22
  billion capital program underway Keystone will have the capacity to deliver
  1.1 million barrels of oil per day to U.S. markets


Linking
  northern gas to market 16 Alaska Pipeline Project The Alaska Pipeline Project
  marked a significant milestone in January 2010 by filing an open season plan
  with the U.S. Federal Energy Regulatory Commission (FERC). Billed as the
  largest construction project in the history of North America, the US$32
  billion to US$41 billion pipeline would extend 2,737 km (1,700 miles) from
  Prudhoe Bay, Alaska to Alberta where the natural gas could be delivered on
  existing pipeline systems serving major North American markets. An alternate
  route would see the natural gas move from the North Slope to Valdez, Alaska
  where it would be converted to liquefied natural gas in a facility to be
  built by others and then delivered by ship to North American and
  international markets. If successful, the project could be operational in
  2020. 17 Mackenzie Gas Pipeline Project The Mackenzie Gas Pipeline initiative
  reached a milestone with the release of the Joint Review Panel report in
  December 2009. The parties advancing the proposed 1,200 km (746 mile)
  pipeline remain focused on obtaining regulatory approval and the Canadian
  governments support of an acceptable fiscal framework. Energy 7 Halton Hills
  Work on the $700 million, 683 MW Halton Hills generating station is nearing
  completion and the plant is expected to be operational in third quarter 2010.
  Located 40 kilometres (25 miles) west of Toronto, Halton Hills will be
  capable of producing enough electricity to power nearly 700,000 homes. 8
  Oakville In 2009, TransCanada was awarded a 20-year Clean Energy Supply
  contract to build, own and operate the 900 MW Oakville generating station in
  Oakville, Ontario. TransCanada expects to invest approximately $1.2 billion
  in the natural gas-fired, combined-cycle plant which is scheduled to start producing
  power early in 2014. 13 Coolidge Construction of the US$500 million, 575 MW
  Coolidge power plant began in mid-2009. Located near Phoenix, Arizona, the
  plant will provide a quick response to peak power demands in the region. The
  plant is expected to be in service in second quarter 2011. 17 Bruce Power
  Progress continues on the refurbishment and restart of Bruce A Units 1 and 2,
  with reassembly of the reactors now taking place. TransCanada expects to
  invest approximately $2 billion in the project. When completed in 2011, the
  two units will be capable of delivering 1,500 MW of electricity to the
  Ontario market  enough to power one and a half million homes. TransCanada
  owns 48.8 per cent of Bruce A and 31.6 per cent of Bruce B. 18 Cartier 19
  Kibby The Cartier and Kibby Wind power projects will generate clean,
  renewable electricity for thousands of homes. Cartier, 62 per cent owned by
  TransCanada, is the largest wind power project in Canada, valued at
  approximately $1.1 billion. Its five phases will ultimately be capable of
  producing 590 MW of electricity. Three of the five phases are now operating
  with completion of the two remaining phases expected by 2012. TransCanada
  also completed the first phase of the Kibby project in late 2009.
  Construction of the second phase continues and is expected to be placed in
  service in third quarter 2010. Once completed, the US$350 million, 132 MW
  initiative will be the largest wind power development in Maine, providing
  enough green energy for 50,000 homes in the state.

|Chairman's
Message |  | 2009 was an interesting year; the global economy was in turmoil and most companies were unable to raise the money they needed to fund their businesses. Yet in the midst of such a severe financial crisis,

|PHOTO |  | It started in January with the issuance of US$2 billion in the debt capital markets, followed weeks later by another $700 million in the Canadian market. This set the stage for the rest of the year. In total,
TransCanada raised approximately $6 billion in debt and equity in 2009  money used to finance TransCanada's ongoing $22 billion capital program  a program our leadership is committed to
moving forward.
Investing in the future today, however, has had an impact. The tools we used to raise the necessary capital affected our short-term earnings per share along with our share price, but we felt it prudent not to deviate from our long-term growth
strategy  a strategy that we are confident will generate significant shareholder value in the years to come.
The crown jewel of TransCanada's capital program is Keystone  the oil pipeline TransCanada now owns outright, having acquired the remaining interest in the project from ConocoPhillips. As well, our energy business continued to grow in
2009 as the Portlands Energy Centre in Toronto began operations, construction began or continued on new generation facilities in Ontario and Arizona and wind turbines started producing clean energy in Maine thanks to our Kibby project.
The ability to execute this slate of projects is a true measure of the capabilities of TransCanada.
As the construction is completed and the projects move to operations over the next couple of years, the contribution to earnings from these new assets will be meaningful. This strong financial and operating performance and prudent, sustained growth
will lead to positive returns for our shareholders.
With that in mind, in February 2010, the Board approved an increase in the dividend on common shares for the tenth consecutive year. The new quarterly rate of $0.40 per common share or $1.60 annually, is a five per cent increase over the
previous amount. A three per cent discount on common shares issued from treasury under our dividend reinvestment plan will also continue. This plan allows common and preferred shareholders to purchase additional common shares by reinvesting
their cash dividends.
TransCanada's Board of Directors clearly understands its corporate governance role and we are honoured to be recognized among the top performers in this country. There are an increasing number of issues that require dialogue with shareholders and, as
always, we look forward to that exchange. We also believe our executive leadership and our employees must remain focused on the long-term  not just on short-term performance. Our shareholders should expect nothing less.
I will close by thanking those who helped ensure this was another successful year for our company  TransCanada's executive leadership team and the 4,000 men and women who exemplify each and every day the values that form the
foundation of our success; responsibility, integrity, innovation and collaboration. They should all be proud of their accomplishments.

|PHOTO |  | It will take a sound, strategic approach to achieve this goal  a strategy rooted in the philosophy of our past successes and one that embraces innovation as we move forward  all the
while keeping our focus on the fundamentals to ensure long-lasting success. TransCanada produced strong financial results in 2009 despite difficult times in the North American economy. Today, we are nearly half-way through an unprecedented $22 billion capital
program  a program that continues to progress as planned. To finance our capital program, TransCanada chose a prudent path. Rather than compromise our strong financial position, we issued a combination of debt and equity to fund
our projects. Our work is not done. We remain focused on carefully executing our capital program  while we cultivate the very best suite of long-term opportunities in
the industry.
|      |  | In 2009, TransCanada continued to deliver strong financial and operating results. Net income applicable to common shares totalled $1.4 billion or $2.11 per share. Comparable earnings(1) were $1.3 billion or $2.03 per share. Funds
generated from operations(1) increased to a record $3.1 billion on the strength of our diverse portfolio of North American energy infrastructure assets. Strong results in a difficult economic environment.                                                                                                                                                                                                                                                                                                                                                                                                                                     
|      |  | Over the past 10 years we have constructed and acquired approximately $20 billion in stable, value-creating pipeline and energy infrastructure assets. These investments have transformed TransCanada into the industry leader it
is today.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
|      |  | Our investments have been both large and profitable. Since 1999, comparable earnings per share(1) have almost doubled from $1.08 in 1999 to $2.03 in 2009. Over that same timeframe, funds generated from operations(1) have
tripled from $1.0 billion in 1999 to $3.1 billion in 2009.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
|      |  | Looking forward, we expect that our current $22 billion capital program will lead to another period of sustained growth in earnings, cash flow and dividends as a number of attractive, low-risk projects are placed in service over the next
five years.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
|      |  | This enabled our Board of Directors to increase the dividend on common shares for the tenth consecutive year in February 2010. Most recently, we increased the dividend to $1.60 per share on an annualized basis, an increase of five per cent
over 2009. Our Board of Directors also approved the issuance of common shares from treasury at a three per cent discount under our Dividend Reinvestment Plan. This provides shareholders with an opportunity to participate in the future growth of
the company by reinvesting their dividends in additional common shares.

| |  | Energy infrastructure is a long-cycle, capital intensive business. To be successful we must maintain a strong financial position and significant liquidity. This will help ensure we have the ability to endure turbulent economic times.

| |  | Our strong access to the capital markets allowed TransCanada to raise approximately $6 billion in 2009, including $1.8 billion of common equity. While this will have an impact on our reported earnings per share in the near-term, it also
gives us the financial flexibility needed to fund the remainder of our existing capital program.                                                                               
| |  | By raising the necessary capital, TransCanada was able to continue to advance projects such as Keystone  an oil pipeline system that will be one of the largest in North America. Our company also purchased ConocoPhillips' remaining
interest in the project, making us the sole owner. We are now looking forward to delivering crude oil to refineries in Illinois later this year.                                    
| |  | For the first time in the 30-year history of efforts to develop Alaska's North Slope gas resources, a plan has been filed with the U.S. Federal Energy Regulatory Commission (FERC) seeking approval to hold an open season.                                                                                                                                                                                                
| |  | The plan was submitted by TransCanada and ExxonMobil. The Alaska Pipeline Project provides the best opportunity for success to bring up to 4.5 billion cubic feet per day (Bcf/d) of natural gas to market.                                                                                                                                                                                                                 
| |  | In December 2009, the Joint Review Panel released its report on the proposed Mackenzie Gas Pipeline Project. The panel felt the project 'would deliver valuable and lasting overall benefits' and concluded it should go forward. We will continue to work
with the Canadian Government and the other project proponents in the hope that Mackenzie becomes a reality.                                                      
| |  | Our North Central Corridor expansion is closing in on an important milestone, with construction expected to be completed in the second quarter of 2010. This 300 kilometre pipeline will help to optimize gas flows on the Alberta System and is also
expected to reduce fuel consumption by 50 per cent, saving shippers $50 million to $75 million a year.                                                                
| |  | We were pleased with the news the National Energy Board (NEB) determined the Alberta System is within federal jurisdiction and would be regulated by the NEB. This will allow us to extend our pipeline across provincial borders and provide more
competitive transportation options to producers.                                                                                                                         
| |  | Shale gas plays have received considerable attention this past year. Our vast pipeline network is well positioned to connect these new sources of supply to growing markets. This was evident by our successful open season for the Groundbirch pipeline
in northeast British Columbia. Contracts for approximately 1.1 Bcf/d complement contracts on the nearby Horn River line of 503 million cubic feet per day (mmcf/d).
| |  | Further south, we are anticipating FERC approval for our Bison project. The 487 kilometre natural gas pipeline is expected to be operational in the fourth quarter of this year, linking a growing supply of natural gas in the U.S. Rockies to
U.S. Midwest markets.                                                                                                                                                       
| |  | In Mexico, we were awarded a 25-year contract to build a pipeline that takes gas from an LNG terminal under construction in Manzanillo on to Guadalajara, a distance of 305 kilometres. The line is expected to be operational
in 2011.

| |  | We were pleased last spring as the 550 MW Portlands Energy Centre began operations. Capable of supplying 25 per cent of Toronto's electrical needs, the plant was placed in service on time and under budget. TransCanada is a
50 per cent owner.                                                                                                                                                                                                                                  
| |  | Another of our key projects that began operations in 2009 was the first phase of the Kibby wind project in Maine. Twenty-two of the 44 turbines are producing clean energy. The remainder of the turbines should be operational later this year.
When completed the project will be capable of powering approximately 50,000 homes.                                                                                                                                                
| |  | North of the border, construction continues on the largest wind power project in Canada. Three of the five wind farms that make up the Cartier project are producing energy. TransCanada is a 62 per cent owner.                                                                                                                                                                                                                                                                   
| |  | Work continues at Bruce Power on the refurbishment and restart of Units 1 and 2. This work at North America's largest power plant is expected to be complete in 2011. Our presence in the Ontario power market will be further strengthened as
the Halton Hills generating station outside of Toronto begins operations in 2010 and we continue to advance the Oakville power project  a 900 MW facility for which TransCanada was awarded the contract to build, own
and operate.
| |  | Finally, we began construction on yet another power facility in the summer of 2009  a 575 MW power project in Arizona  the Coolidge generating station.                                                                                                                                                                                                                                                                                                                          
| |  | TransCanada is focused on growth opportunities where we have or can develop a significant competitive advantage. As with all of our projects, our goal is to complete them safely, on time and on budget. By applying our extensive project development
and execution capabilities to these projects, along with our strong operating and commercial expertise, we will set the stage for long-term growth and value creation.

6MANAGEMENT'S DISCUSSION AND ANALYSIS

---





Management's Discussion and Analysis (MD&A) dated February 22, 2010 should be read in conjunction with the accompanying audited Consolidated
Financial Statements of TransCanada Corporation (TransCanada or the Company) and the notes thereto for the year ended December 31, 2009 which are prepared in accordance with Canadian generally
accepted accounting principles (GAAP). This MD&A covers TransCanada's financial position and operations as at and for the year ended December 31, 2009. "TransCanada" or "the Company" includes
TransCanada Corporation and its subsidiaries unless otherwise indicated. Amounts are stated in Canadian dollars unless otherwise indicated. Abbreviations and acronyms not defined in this MD&A are
defined in the Glossary of Terms in the Company's 2009 Annual Report.

TRANSCANADA OVERVIEW

At December 31, 2009, TransCanada had completed approximately $10 billion of its $22 billion capital program. Upon completion of this program, these assets
are expected to generate additional annual earnings before interest, taxes, depreciation and amortization (EBITDA) of approximately $2.5 billion. The Company expects to complete most of the
projects in its capital growth program by the end of 2013. Over the longer term, TransCanada intends to continue to develop its substantial asset portfolio and pursue other large-scale pipeline and
energy infrastructure projects. TransCanada is committed to maintaining the financial strength required to invest in the development of North American energy infrastructure and respond to
shifting energy supply-demand dynamics.

TransCanada's 2009 Key Accomplishments

Pipelines Assets

The TransCanada pipeline network, including assets under construction and development, consists of more than 60,000 kilometres (km) (37,000 miles) of wholly owned
and 8,800 km (5,468 miles) of partially owned natural gas pipelines and transports 20 per cent of the natural gas consumed in North America. TransCanada's natural
gas pipelines link gas supplies from Western Canada, the United States (U.S.) mid-continent and Gulf of Mexico to premium North American markets. These assets are well
positioned to connect emerging natural gas supplies, including northern gas, northeastern British Columbia (B.C.) and U.S. shale gas, Rocky Mountain gas and offshore liquefied natural gas (LNG)
imports, to growing markets.

TransCanada's
Alberta System gathered 66 per cent of the natural gas produced in Western Canada or 14 per cent of total North American
production in 2009. TransCanada transports natural gas from the Western Canada Sedimentary Basin (WCSB) to Eastern Canada and the U.S. West, Midwest, and Northeast through three wholly owned
pipeline systems: the Canadian Mainline, GTN and Foothills. TransCanada also transports natural gas from the WCSB to Eastern Canada and to the U.S. West, Midwest and Northeast through six
partially owned natural gas pipeline systems: Great Lakes, Iroquois, Portland, TQM, Northern Border and Tuscarora. Certain of these pipeline systems are held through the Company's
38.2 per cent interest in TC PipeLines, LP (PipeLines LP).

ANR
transports natural gas from producing fields located primarily in Texas, Oklahoma, the Gulf of Mexico and Louisiana to markets located in Wisconsin, Michigan, Illinois,
Ohio and Indiana. It also connects with numerous other natural gas pipelines, providing customers with access to diverse sources of North American supply, including Western Canada and the Rocky
Mountain region, and to a variety of end-user markets in the midwestern and northeastern U.S. ANR owns and operates 250 billion cubic feet (Bcf) of regulated natural
gas storage capacity in Michigan. TransCanada also serves natural gas markets in Mexico through its Tamazunchale and North Baja pipelines, and will expand service to markets in Mexico with the
Guadalajara pipeline which is under construction.

MANAGEMENT'S DISCUSSION AND ANALYSIS7

In
addition, TransCanada is constructing the approximately 6,200 km (3,853 miles) Keystone crude oil pipeline. Keystone is expected to transport
1.1 million barrels per day (Bbl/d) of crude oil from Hardisty, Alberta to U.S. Midwest markets at Wood River and Patoka, Illinois, and to Cushing, Oklahoma, and to U.S. Gulf
Coast markets. The pipeline will provide a low-cost shipping option to customers and is supported by long-term contracts with creditworthy counterparties. The first phase of
Keystone, which is to Wood River and Patoka, is expected to commence delivery of crude oil in mid-2010 with the remaining phases expected to commence service in first quarter 2011 and
first quarter 2013. In the medium to long term, opportunities for further additions to Keystone would expand the pipeline's transport capacity to 1.5 million Bbl/d from
1.1 million Bbl/d.

Energy Assets

TransCanada's Energy business has grown to more than 11,700 megawatts (MW) in 2009 from 754 MW in 1999, including assets under construction and development. The
Company's diverse power generation portfolio of primarily low-cost, base load and long-term contracted facilities comprises a total of 20 plants in Alberta, Arizona,
Eastern Canada, New England and New York City.

TransCanada's
Western Power business comprises approximately 2,600 MW of power supply in Alberta and the western U.S. The Western Power portfolio in Alberta
consists of three long-term power purchase arrangements (PPA): the Sheerness and Sundance A and B coal-fired plants, and five natural gas-fired cogeneration
facilities consisting of MacKay River, Carseland, Bear Creek, Redwater and Cancarb. The Sundance A PPA expires in 2017 and the Sundance B and Sheerness PPAs expire in 2020. The other power facility in
the Western Power portfolio is Coolidge, a natural gas-fired peaking facility under construction in Arizona whose output will be sold under a 20 year PPA. Coolidge is expected to be
in service in second quarter 2011. Western Power's marketing business serves an integral function by purchasing and reselling electricity and natural gas to maximize the return from the Western Power
assets.

The
Eastern Power business is comprised of approximately 2,900 MW of power generation capacity, including facilities under construction. Eastern Power's operating
assets consist of Bécancour, three of five Cartier Wind farms, Portlands Energy and Grandview. Power from Bécancour and Cartier Wind is sold to
Hydro-Québec through 20 year power purchase contracts. Output from the Portlands Energy and Grandview facilities is sold through 20 year contracts with the Ontario Power
Authority (OPA) and Irving Oil Limited (Irving), respectively. Halton Hills and the remaining two Cartier Wind farms which are under construction are expected to be in service in 2010, 2011 and 2012,
respectively. Oakville, which is currently under development, is expected to be in service in first quarter 2014. Once operational, Oakville and Halton Hills will sell power to the OPA through
20 year contracts and the remaining two Cartier Wind farms will sell power to Hydro-Québec through 20 year contracts.

TransCanada
has a 48.8 per cent interest in Bruce A and a 31.6 per cent interest in Bruce B, which together comprise the Bruce
Power nuclear generating facility. Bruce A has four 750 MW reactors, two of which are being refurbished, and Bruce B has four operational reactors with a combined capacity of
3,200 MW. Through a
contract with the OPA, all of the output from Bruce A is effectively sold at a fixed price and the output from Bruce B is subject to a floor price.

TransCanada's
U.S. Power assets have approximately 3,800 MW of power generation capacity, including facilities under construction. The operating assets in the
U.S. Power portfolio consist of Ravenswood, TC Hydro, OSP and phase one of Kibby Wind. Phase two of Kibby Wind is under construction and is expected to be placed into service in third quarter
2010. U.S. Power sells power to wholesale, commercial and industrial customers through TransCanada Power Marketing Ltd. (TCPM), a wholly owned subsidiary of TransCanada.

GRAPHIC

TransCanada
has developed a significant non-regulated natural gas storage business in Alberta where the Company owns or has rights to 129 Bcf or
approximately one-third of natural gas storage capacity in the province.

TRANSCANADA'S STRATEGY

TransCanada's vision is to be the leading energy infrastructure company in North America, focusing on pipelines and power generation opportunities in regions where it
has or can develop a significant competitive advantage. TransCanada's key strategies continue to evolve with the Company's growth and development and its changing business environment. TransCanada's
corporate strategy integrates five fundamental value-creating activities:

Maximize the full-life value of TransCanada's infrastructure assets and commercial positions

TransCanada relies on a low-risk business model to maximize the full-life value of its existing assets and commercial positions. In Pipelines, large scale natural gas and crude
oil pipelines connect long life supply basins with stable and growing markets, generating predictable, sustainable cash flows and earnings of a long term nature. In Energy, highly efficient large
scale power generation facilities supply power markets through long term power purchase and sale agreements and low-volatility shorter term commercial arrangements. TransCanada's growing investments
in natural gas, nuclear, wind and hydro generating facilities demonstrate the Company's commitment to sustainable, clean energy. Long-life infrastructure assets and long term commercial arrangements
will continue as cornerstones of TransCanada's business model.

Cultivate a focused portfolio of high quality development options

The Company's core regions within North America are the primary focus of growth initiatives in Pipelines and Energy. TransCanada will continue to pursue opportunities to
connect long-life shale and conventional gas resources in western Canada, northern Canada, Alaska, U.S. Rockies, U.S. midcontinent and Gulf Coast supply regions. TransCanada will continue to pursue
opportunities to connect growing crude oil volumes from the Alberta oilsands to preferred North American markets. The Company will continue to assess pipeline acquisition opportunities that complement
its existing pipeline networks and provide access to new supply and market regions. In Energy, the Company will continue to focus on low-cost, long-life base load power generating and natural gas
storage assets supported by firm, long-term contracts with reputable counterparties. Selected opportunities will move forward to full development and construction when market conditions are
appropriate and project risks are manageable.

Commercially develop and physically execute new asset investment programs

TransCanada expects to substantially complete construction of assets under its current $22 billion capital program by the end of 2013. The Company is focused on
completing its capital projects on time and on budget, enabling it to meet commitments to customers and to deliver attractive, long-term returns to shareholders. The current capital program is
characterized by highly contracted, long-term revenue streams with limited exposure to commodity prices.

MANAGEMENT'S DISCUSSION AND ANALYSIS9

Capital
cost risks are managed by TransCanada's strong and experienced project management teams and industry-leading project management practices.

Maximize TransCanada's competitive strengths

TransCanada continues to build competitive strength in areas that directly drive long-term shareholder value. The Company relies on its scale, presence, operating capabilities,
strong leadership and capable teams to compete effectively and deliver outstanding value to its customers. A disciplined approach to capital investment combined with a low cost of capital allows the
Company to create significant shareholder value from large capital projects. TransCanada recognizes that constructive relationships with key customers and stakeholders are critically important in the
long-term energy infrastructure business. The Company continues to identify and build on all aspects of competitive strength.

Maximize TransCanada's reputation and standing in financial markets

TransCanada values its reputation for consistent financial performance and long term financial stability. The Company clearly communicates its financial performance to equity
and debt investors, providing insight into both value upside and business risks. The Company works to sustain the trust and support of its long-term investors and to attract new investors who see long
term value in a disciplined approach to the energy infrastructure business.

SEGMENT RESULTS

Effective January 1, 2009, TransCanada revised the information presented in the tables of this MD&A to better reflect the operating and financing structure of the
Company. The Pipelines and Energy results summaries are presented geographically by separating the Canadian and U.S. portions of each segment. The Company believes this new format more clearly
describes the financial performance of its businesses. The new format presents EBITDA and earnings before interest and taxes (EBIT), which the Company believes provide greater transparency and more
useful information with respect to the performance of its individual assets. Segmented information has been retroactively reclassified to reflect these changes. These changes had no impact on reported
consolidated net income.

RESULTS OF OPERATIONS

In 2009, net income was $1,380 million and net income applicable to common shares was $1,374 million or $2.11 per share compared to net income of
$1,440 million or $2.53 per share in 2008. Net income in 2007 was $1,223 million or $2.31 per share.

Net
income applicable to common shares in 2009 included $30 million of favourable income tax adjustments arising from a reduction in the Province of Ontario's
corporate income tax rates, an $18 million after tax dilution gain resulting from TransCanada's reduced interest in PipeLines LP after a public offering of PipeLines LP common
units in fourth quarter 2009, and $1 million of after tax net unrealized gains (2008  nil; 2007  net gains of
$7 million after tax) resulting from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts.

Net
income in 2008 included $152 million of after tax gains on shares received by GTN and Portland from the Calpine bankruptcy settlements, $10 million after
tax of GTN lawsuit settlement proceeds and a $27 million after tax writedown of costs previously capitalized for Broadwater. Net income in 2008 also included $26 million of favourable
income tax adjustments from an internal restructuring and realization of losses. Net income in 2007 included $102 million of favourable income tax adjustments relating to changes in Canadian
federal and provincial corporate income tax legislation, the resolution of certain tax matters and an internal restructuring, and an after tax gain of $14 million on the sale of land.

Comparable
earnings in 2009, 2008 and 2007 were $1,325 million or $2.03 per share, $1,279 million or $2.25 per share and $1,100 million or $2.08 per
share, respectively, and excluded the above-noted items.

Comparable
earnings increased $46 million and decreased $0.22 per share in 2009 compared to 2008. The increase in comparable earnings reflected:



Comparable
earnings increased $179 million or $0.17 per share in 2008 compared to 2007 due to an increase in Energy's comparable EBIT, primarily as a result of higher
realized power prices and a full year of earnings from ANR, partially offset by unrealized losses from changes in the fair value of interest rate derivatives.

Earnings
per share in 2009 and 2008 was reduced by the increase in the average number of shares outstanding following the Company's issuance of 58.4 million,
35.1 million and 34.7 million common shares in second quarter

FORWARD-LOOKING INFORMATION

This MD&A may contain certain information that is forward looking and is subject to important risks and uncertainties. The words "anticipate", "expect", "believe", "may",
"should", "estimate", "project", "outlook", "forecast" or other similar words are used to identify such forward-looking information. Forward-looking statements in this document are intended to provide
TransCanada security holders and potential investors with information regarding TransCanada and its subsidiaries, including management's assessment of TransCanada's and its subsidiaries' future
financial and operational plans and outlook. Forward-looking statements in this document may include, among others, statements regarding the anticipated business prospects and financial performance of
TransCanada and its subsidiaries, expectations or projections about the future, strategies and goals for growth and expansion, expected and future cash flows, costs, schedules, operating and financial
results and expected impact of future commitments and contingent liabilities. All forward-looking statements reflect TransCanada's beliefs and assumptions based on information available at the time
the statements were made. Actual results or events may differ from those predicted in these forward-looking statements. Factors that could cause actual results or events to differ materially from
current expectations include, among others, the ability of TransCanada to successfully implement its strategic initiatives and whether such strategic initiatives will yield the expected benefits, the
operating performance of the Company's pipeline and energy assets, the availability and price of energy commodities, capacity payments, regulatory processes and decisions, changes in environmental and
other laws and regulations, competitive factors in the pipeline and energy sectors, construction and completion of capital projects, labour, equipment and material costs, access to capital markets,
interest and currency exchange rates, technological developments and economic conditions in North America. By its nature, forward-looking information is subject to various risks and uncertainties,
including those material risks discussed in the Pipelines, Energy and Risk Management and Financial Instruments sections in this MD&A, which could cause TransCanada's actual results and experience to
differ materially from the anticipated results or expectations expressed. Additional information on these and other factors is available in the reports filed by TransCanada with Canadian securities
regulators and with the U.S. Securities and Exchange Commission (SEC). Readers are cautioned not to place undue reliance on this forward-looking information, which is given as of the date it is
expressed in this MD&A or otherwise, and not to use future-oriented information or financial outlooks for anything other than their intended purpose. TransCanada undertakes no obligation to
update publicly or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as required by law.

NON-GAAP MEASURES

TransCanada uses the measures "comparable earnings", "comparable earnings per share", "EBITDA", "comparable EBITDA", "EBIT", "comparable EBIT" and "funds generated from
operations" in this MD&A. These measures do not have any standardized meaning prescribed by GAAP. They are, therefore, considered to be non-GAAP measures and may not be comparable to
similar measures presented by other entities. Management of TransCanada uses these non-GAAP measures to improve its ability to compare financial results among reporting periods and to
enhance its understanding of operating performance, liquidity and ability to generate funds to finance operations. These non-GAAP measures are also provided to readers as additional
information on TransCanada's operating performance, liquidity and ability to generate funds to finance operations.

EBITDA
is an approximate measure of the Company's pre-tax operating cash flow. EBITDA comprises earnings before deducting interest and other financial charges,
income taxes, depreciation and amortization, and non-controlling interests. EBIT is a measure of the Company's earnings from ongoing operations. EBIT comprises earnings before deducting
interest and other financial charges, income taxes and non-controlling interests.

16MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Management
uses the measures of comparable earnings, comparable EBITDA and comparable EBIT to better evaluate trends in the Company's underlying operations. Comparable
earnings, comparable EBITDA and comparable EBIT comprise net income applicable to common shares, EBITDA and EBIT, respectively, adjusted for specific items that are significant but are not reflective
of the Company's underlying operations in the year. Specific items are subjective, however, management uses its judgement and informed decision-making when identifying items to be excluded in
calculating comparable earnings, comparable EBITDA and comparable EBIT, some of which may recur. Specific items may include but are not limited to certain income tax refunds and adjustments, gains or
losses on sales of assets, legal and bankruptcy settlements, and certain fair value adjustments. The Segment Results table in this MD&A presents a reconciliation of comparable earnings, comparable
EBITDA, comparable EBIT and EBIT to net income and net income applicable to common shares. Comparable earnings per share is calculated by dividing comparable earnings by the weighted average number of
common shares outstanding for the year.

Funds
generated from operations comprises net cash provided by operations before changes in operating working capital. A reconciliation of funds generated from operations to
net cash provided by operations is presented in the Summarized Cash Flow table in the Liquidity and Capital Resources section of this MD&A.

OUTLOOK

TransCanada's corporate strategy is underpinned by long-term growth, focusing on its core strengths in its Pipelines and Energy businesses. In 2010 and beyond,
TransCanada expects net income and operating cash flow, combined with a strong balance sheet and proven ability to access capital markets, to provide the financial resources needed to complete its
current capital expenditure program, continue to pursue long-term growth opportunities and create additional value for its shareholders. This strategy will be executed with the same
discipline and deliberate manner that have characterized TransCanada's current capital expenditure program. TransCanada believes this prudence is especially important in the current economic
environment in North America. In 2010, the Company will significantly advance its capital program and continue to implement its strategy to grow the Pipelines and Energy businesses as discussed in the
TransCanada's Strategy section of this MD&A.

In
2010, the Pipelines segment is expected to begin generating EBITDA from the initial phase of Keystone. Keystone's EBITDA will increase as additional phases are completed
and brought into service. Pipelines' EBITDA may be affected by the expiry of long-term contracts, variances in throughput volume particularly on the U.S. pipelines, customer
settlements and decisions made by applicable regulatory authorities.

Energy's
EBITDA in 2010 will be affected by commodity price changes in instances where TransCanada has not entered into contracts that manage these fluctuations or in
circumstances where existing sales contracts expire and are replaced with new contracts entered into at prevailing market prices. Energy's EBITDA will also be impacted by fluctuations in capacity
prices in the New York City market where Ravenswood operates and in New England. Furthermore, Energy's EBITDA in 2010 will be positively impacted by assets that were placed in service
during 2009 and assets that are expected to be placed in service in 2010.

TransCanada
also expects earnings in 2010 to be impacted by a reduction in capitalized interest and an increase in depreciation as new assets are placed into service.

On
a consolidated basis, the impact of changes in the value of the U.S. dollar on U.S. Pipelines and Energy EBIT is largely offset by the impact of the changes
in the value of the U.S. dollar on U.S. dollar interest expense. The resultant net exposure is managed using derivatives, effectively reducing the Company's exposure to changes in
foreign exchange rates. The average U.S. dollar exchange rate for the year ended December 31, 2009 was 1.14 (2008 and 2007  1.07).

The
Company's results in 2010 may be affected by a number of factors and developments as discussed throughout this MD&A including, without limitation, the factors and
developments discussed in the Forward-Looking Information, Pipelines  Business Risks and Energy  Business Risks sections.
Refer to the Pipelines  Outlook and Energy  Outlook sections of this MD&A for further discussion of outlook.
Commencing January 1, 2011, the Company's results will be impacted by the adoption of International Financial Reporting Standards (IFRS) as discussed in the Accounting
Changes  Future Accounting Changes section in this MD&A.

MANAGEMENT'S DISCUSSION AND ANALYSIS21

---



Pipelines generated comparable EBIT of $2,063 million in 2009 compared to $2,030 million in 2008. Comparable EBIT in
2009 excluded the $29 million pre-tax dilution gain resulting from TransCanada's reduced interest in PipeLines LP, which occurred following the public issuance of common
units by PipeLines LP in November 2009. Comparable EBIT in 2008 excluded the $279 million of gains received by Portland and GTN from the bankruptcy settlements with Calpine and
the $17 million of proceeds received by GTN from a lawsuit settlement with a software supplier. Comparable EBIT in 2007 was $2,056 million.

PIPELINES  FINANCIAL ANALYSIS

Canadian MainlineThe Canadian Mainline is regulated by the NEB, which sets tolls that provide TransCanada with the
opportunity to recover projected costs of transporting natural gas, including a return on the Canadian Mainline's average investment base. The NEB also approves new facilities before construction
begins. Canadian Mainline's EBITDA is affected by changes in investment base, the ROE, the level of deemed common equity, potential incentive earnings and changes in the level of depreciation,
financial charges and income taxes recovered in revenue on a flow-through basis.

The
Canadian Mainline currently operates under a five year tolls settlement effective from 2007 to 2011. The cost of capital reflects an ROE as determined by the NEB's ROE
formula on deemed common equity of 40 per cent.

The
tolls settlement also established certain elements of the Canadian Mainline's fixed operating, maintenance and administration (OM&A) costs for each of the five years.
The variance between actual and agreed-upon OM&A costs accrued entirely to TransCanada from 2007 to 2009, and will be shared equally between TransCanada and its customers in 2010 and 2011.
All other cost elements of the revenue requirement are treated on a flow-through basis. The settlement also allows for performance-based incentive arrangements that the Company believes
are mutually beneficial to TransCanada and its customers.

Net
income of $273 million in 2009 was $5 million lower than $278 million in 2008. The decrease was primarily the result of a lower average investment
base and a lower ROE of 8.57 per cent in 2009 compared to 8.71 per cent in 2008, partially offset by higher OM&A cost savings. Net income of $278 million in 2008 was
$5 million higher than $273 million in 2007 primarily due to higher performance-based incentives, increased OM&A cost savings and an ROE of 8.71 per cent in 2008 compared
to 8.46 per cent in 2007. These increases were partially offset by a lower average investment base.

Comparable
EBITDA of $1,133 million in 2009 was $8 million lower than $1,141 million in 2008. The decrease was primarily due to lower revenues as a
result of recovery of a lower overall return on a reduced average investment base and a lower ROE in 2009. The decrease in revenues was partially offset by higher OM&A cost savings and recovery of
higher depreciation in 2009. EBITDA of $1,141 million in 2008 was $66 million lower than $1,207 million in 2007 primarily due to lower revenues as a result of the recovery of
lower depreciation, financial charges and income taxes in 2008. The decrease in revenues was partially offset by higher EBITDA from performance-based incentives, OM&A cost savings and
higher ROE.

GRAPHIC

Alberta SystemEffective April 29, 2009, the Alberta System became federally regulated by the NEB under
theNational Energy Board Act(Canada). The Alberta System was previously regulated by the Alberta Utilities Commission (AUC), primarily under the
provisions of theGas Utilities Act(Alberta) andPipeline Act(Alberta). The Alberta System's EBITDA is
affected by changes in investment base, the ROE, the level of deemed common equity, potential incentive earnings and changes in the level of depreciation, financial charges and income taxes recovered
in revenue on a flow-through basis.

The
Alberta System operates under the 2008 - 2009 Revenue Requirement Settlement originally approved by the AUC in December 2008 and
subsequently approved by the NEB following the Alberta System's transfer to federal jurisdiction. In December 2009, the NEB approved TransCanada's application to establish final 2009 tolls. In
2007, the Alberta System operated under the 2005 - 2007 Revenue Requirement Settlement approved by the AUC in June 2005.

As
part of the 2008 - 2009 Revenue Requirement Settlement, fixed amounts were established for ROE, income taxes and certain OM&A costs. Any
variances between actual costs and those agreed to in the settlement accrued to TransCanada, subject to an ROE and income tax adjustment mechanism that accounted for variances between actual and
settlement rate base, and income tax assumptions. The other cost elements of the settlement were treated on a flow-through basis.

The
Alberta System's net income of $168 million in 2009 was $23 million higher than in 2008, primarily due to higher settlement earnings and a higher average
investment base in 2009. Net income of $145 million in 2008 was $7 million higher than in 2007 due to increased earnings as a result of the 2008 - 2009 Revenue
Requirement Settlement. Earnings in 2007 reflected an ROE of 8.51 per cent on deemed common equity of 35 per cent.

The
Alberta System's comparable EBITDA of $728 million in 2009 was $36 million higher than in 2008, primarily due to higher settlement earnings and a higher
average investment base in 2009 as well as increased revenues as a result of the recovery of higher financial charges, partially offset by lower income taxes. EBITDA of $692 million in 2008 was
$83 million lower than in 2007. The decrease was due to lower revenues as a result of the recovery of lower depreciation, income taxes and financial charges, partially offset by increased
earnings as a result of the 2008 - 2009 Revenue Requirement Settlement.

Other Canadian PipelinesComparable EBITDA from Other Canadian Pipelines was $59 million in 2009 compared
to $50 million in 2008. The increase was primarily due to the NEB decision reached in March 2009 on TQM's cost of capital for the years 2007 and 2008. EBITDA was $50 million in
2008 compared to $51 million in 2007.

ANRThe operations of ANR are regulated primarily by the U.S. Federal Energy Regulatory Commission
(FERC). ANR provides natural gas transportation, storage and various capacity-related services to a variety of North American customers. ANR's transmission system has a peak-day capacity
of 6.8 billion cubic feet per day (Bcf/d). Due to the seasonal nature of its business, ANR's volumes and revenues are generally higher in the winter months. ANR also owns and operates
250 Bcf of regulated underground natural gas storage facilities in Michigan. ANR's natural gas storage and transportation services operate under current FERC-approved tariffs. These
tariffs include maximum and minimum rates for services and permit ANR to discount or negotiate rates on a non-discriminatory basis.

ANR
Pipeline Company (ANR Pipeline) rates were established pursuant to a settlement approved by the FERC effective November 1997. ANR Storage Company's rates
were established pursuant to a settlement approved by the FERC effective June 1990. None of ANR's FERC-regulated operations are required to file for new rates at any time in the
future, nor are any of the operations prohibited from filing a rate case.

ANR's
comparable EBITDA in 2009 was $347 million, which was consistent with 2008. Higher transportation and storage revenues, as a result of expansion projects,
increased utilization and favourable pricing on existing capacity, and the positive impact of a stronger U.S. dollar in 2009 were offset by lower incidental natural gas sales, primarily due to
lower prices, and higher OM&A and business development costs. Comparable EBITDA in 2008 was $347 million compared to $272 million in 2007. The increase was primarily due to a full year
of earnings in 2008 and increased revenue from new growth projects, partially offset by higher OM&A costs.

GTNGTN is regulated by the FERC and is operated in accordance with FERC-approved tariffs that
establish maximum and minimum rates for various services. GTN's pipeline rates were established pursuant to a settlement approved by the FERC in January 2008, and these rates were effective
January 1, 2007. Under the settlement, a five-year moratorium commencing January 1, 2007 was established during which GTN and the settling parties are prohibited from taking
certain actions, including any filings to adjust rates. The settlement also requires GTN to file for new rates to be in effect no later than January 1, 2014. GTN is permitted to discount or
negotiate these rates on a non-discriminatory basis. GTN's EBITDA is affected by variations in contracted volume levels, volumes delivered and prices charged under the various service
types, as well as by variations in the costs of providing services.

GTN's
comparable EBITDA was $195 million in 2009, a decrease of $3 million compared to 2008. The decrease was primarily due to the sale of North Baja to
PipeLines LP in 2009, partially offset by the positive impact of a stronger U.S. dollar in 2009. GTN's EBITDA was $198 million in 2008, an increase of $11 million compared
to 2007 primarily due to lower OM&A expenses.

Other U.S. PipelinesComparable EBITDA from other U.S. Pipelines was $561 million in 2009
compared to $495 million in 2008. The increase was primarily due to the positive impact of a stronger U.S. dollar in 2009, the July 2009 PipeLines LP acquisition of North
Baja, increased revenues from Gas Pacifico resulting from a new transportation agreement and higher short-term revenues from Iroquois. EBITDA was $497 million in 2007.

Business DevelopmentPipelines' business development comparable EBITDA losses increased $25 million in
2009 compared to 2008 primarily due to higher business development costs related to the Alaska pipeline project.

Depreciation and AmortizationDepreciation increased $41 million in 2009 compared to 2008 primarily due
to a stronger U.S. dollar in 2009. The $32 million decrease in depreciation in 2008 compared to 2007 was primarily due to lower depreciation for the Alberta System.

PIPELINES  OPPORTUNITIES AND DEVELOPMENTS

Crude Oil

KeystoneIn August 2009, TransCanada purchased ConocoPhillips' remaining approximate
20 per cent interest in Keystone for US$553 million and the assumption of US$197 million of short-term debt. TransCanada now owns 100 per cent
of Keystone.

In
2008, TransCanada entered into an agreement with ConocoPhillips to increase its equity ownership in Keystone to approximately 80 per cent from
50 per cent, with ConocoPhillips' equity ownership in Keystone being reduced concurrently to approximately 20 per cent from 50 per cent. In 2008 and prior to
August 2009, TransCanada funded 100 per cent of the construction expenditures until the participants' cumulative project capital contributions were aligned with their revised
ownership interests. In 2009, prior to August, TransCanada funded $1.3 billion of cash calls for Keystone, resulting in the Company acquiring an incremental increase in ownership of
approximately 18 per cent for $313 million. In 2008, the Company funded $362 million of cash calls, resulting in an incremental increase in ownership of approximately
12 per cent for $176 million. TransCanada's ownership interest was approximately 80 per cent and 62 per cent in August 2009 and at
December 31, 2008, respectively.

After
gaining regulatory approval in both Canada and the U.S., construction of Keystone began in May 2008. Commissioning of the first phase of Keystone, extending
from Hardisty to Wood River and Patoka with an initial nominal capacity of 435,000 Bbl/d began in late 2009.

In
June 2008, Keystone received approval from the NEB to add new pumping facilities to accommodate deliveries to the Cushing market. The second phase of Keystone is
expected to expand nominal capacity to 591,000 Bbl/d and extend the pipeline to Cushing, with commissioning expected to commence in late 2010 and commercial in service expected to commence in
first quarter 2011.

After
an open season conducted during third quarter 2008, Keystone secured additional firm, long-term shipper contracts on its system. With these commitments,
Keystone filed the necessary regulatory applications in Canada and the U.S. for approval to construct and operate the expansion of the pipeline system that is expected to provide additional
capacity from Western Canada to the U.S. Gulf Coast in early 2013, increasing the total commercial capacity of Keystone to approximately 1.1 million Bbl/d. In September 2009, the
NEB held a hearing to review the application for the new Canadian facilities required for the Keystone Gulf Coast expansion. The NEB is expected to issue a decision in first quarter 2010 on
TransCanada's application to construct and operate the facilities, including the proposed tolling methodology. Facility permits for the U.S. portion of the expansion are expected by fourth
quarter 2010. Construction of the expansion facilities is anticipated to commence in first quarter 2011 following the receipt of the necessary regulatory approvals.

The
capital cost of Keystone, including expansion to the Gulf Coast, if approved, is expected to be approximately US$12 billion with approximately US$5 billion
spent to date. At December 31, 2009, costs of $470 million related to the Keystone expansion to the Gulf Coast are included in intangibles and other assets. Capital costs related to the
construction of Keystone are subject to capital cost risk- and reward-sharing mechanisms with TransCanada's customers.

The
NEB issued approval to commence operations, including commissioning activities, for the Canadian portion of Keystone's facilities, subject to certain conditions. The
approval for the Canadian segment of the pipeline was granted for a period ending approximately nine months from commencement of commercial in service, at a reduced maximum operating pressure (MOP),
which will reduce throughput capacity below initial nominal capacity of 435,000 Bbl/d. Prior to the conclusion of this nine month period, Keystone is required to run additional
in-line inspections on this segment. These inspections and any remedial work are expected to be completed within this nine month period. Following these activities, TransCanada expects the
MOP restriction to be lifted.

MANAGEMENT'S DISCUSSION AND ANALYSIS25

TransCanada
expects Keystone to commence delivery of crude oil from Hardisty, Alberta, to U.S. Midwest markets at Wood River and Patoka, Illinois beginning
mid-2010, and to Cushing, Oklahoma
in first quarter 2011. Pending regulatory approval, an expansion of the system to the U.S. Gulf Coast is expected to commence the delivery of crude oil in early 2013.

TransCanada
expects Keystone to begin generating EBITDA in 2010 with earnings increasing through 2011, 2012 and 2013 as expansion phases commence delivery of crude oil.
Contracted volumes of 217,500 Bbl/d will increase to 910,000 Bbl/d from 2010 to 2013 as commercial in service of the Cushing and Gulf Coast phases commence. Based on current
long-term commitments, Keystone is expected to generate EBITDA of approximately US$1.2 billion in 2013, its first full year of commercial operation servicing both the
U.S. Midwest and Gulf Coast markets. If volumes were to increase to 1.1 million Bbl/d, the full commercial design of the system, Keystone would generate annual EBITDA of approximately
US$1.5 billion. Keystone volumes could be economically expanded to 1.5 million Bbl/d from 1.1 million Bbl/d in response to additional market demand.

NEB Changes

Changes to NEB ROE FormulaIn March 2009, the NEB initiated a process to consider the continuing applicability of its
RH-2-94 Decision. This decision established an ROE adjustment formula tied to Government of Canada bond yields and had formed the basis for determining tolls for certain
pipelines under NEB jurisdiction since 1995. In October 2009, the NEB determined that the RH-2-94 Decision would no longer be in effect. The NEB decided that the
cost of capital would be determined by negotiations between pipeline companies and their shippers or by the NEB if a pipeline company files a cost of capital application. This decision affects
certain NEB-regulated pipelines, including the Canadian Mainline, Alberta System, Foothills and TQM. TransCanada will be working with customers and interested parties to determine the cost of capital
to be used in calculating tolls beginning in 2010 for the Alberta System, Foothills and TQM, and for the Canadian Mainline upon expiry of its existing settlement. If agreements cannot be reached,
applications will be filed with the NEB requesting an appropriate return on capital.

In
November 2009, the Canadian Association of Petroleum Producers and the Industrial Gas Users Association sought leave to appeal the October 2009 NEB decision
to the Federal Court of Appeal and named the NEB as the sole respondent. In January 2010, TransCanada was granted respondent status in the matter and in February 2010 filed its
submission opposing the leave application.

Asset Retirement ObligationsIn May 2009, the NEB issued a decision on the Land Matters Consultation Initiative with
respect to financial issues related to pipeline abandonment. All pipeline companies regulated under theNational Energy Board Act(Canada) will be
required to comply with the framework and action plan set out in the decision. The NEB's goal is to have pipeline companies begin collecting and setting aside funds to cover future abandonment costs
no later than mid-2014. There are several filing deadlines in the action plan with which NEB regulated pipeline companies have to comply, including deadlines for preparing and filing an
estimate of the abandonment costs, developing a proposal for collection of funds through tolls or some other satisfactory method and developing a proposed process to set aside the funds collected. As
a result of this decision, TransCanada has initiated a project to estimate the abandonment costs on its NEB-regulated pipelines. The estimate will be filed with the NEB for approval by
May 31, 2011.

Canadian MainlineThe Canadian Mainline will continue to base its return on the NEB's ROE formula for 2010 and
2011 in accordance with the terms of the current Canadian Mainline tolls settlement. In December 2009, the NEB approved TransCanada's application for 2010 final tolls for the Canadian
Mainline's transportation service, effective January 1, 2010. The 2010 calculated ROE for the Canadian Mainline will be 8.52 per cent, a decrease from 8.57 per cent
in 2009.

26MANAGEMENT'S DISCUSSION AND ANALYSIS

Alberta SystemEffective April 29, 2009, the Alberta System became regulated by the NEB under the National Energy Board Act(Canada). The Alberta System was previously regulated by the AUC. Under federal regulation, TransCanada is able to apply to
the NEB for approval to extend the Alberta System across provincial borders, allowing the Company to provide service to producers outside of Alberta.

In
September 2009, TransCanada began construction on the final phase of the North Central Corridor natural gas pipeline, a 300 km (186 miles) extension
of the Alberta System's northern section. This final phase is expected to be completed by April 2010. The initial phase was completed and operational in 2009. The North Central Corridor
pipeline will provide capacity to accommodate increasing natural gas supply in northwest Alberta and northeast B.C. and growing markets in Alberta, and to offset declining natural gas supply in
northeast Alberta while delivering more natural gas to the Alberta/Saskatchewan border. The total capital cost of the project is estimated to be approximately $800 million.

TransCanada
expects producers will continue to explore and develop new gas fields in Western Canada, particularly in northeastern B.C. and the west and central foothills
regions of Alberta. There is also expected to be significant exploration and development activity aimed at unconventional resources such as coalbed methane and shale gas. The emergence of economically
producible unconventional gas from B.C. shale gas supply, including the Montney and Horn River regions, has the potential to become a significant new opportunity for the Alberta System. While these
areas are in their early stages of development, they appear to be comparable to U.S. shale gas supply volumes. Current estimates of the potential gas supply from these two areas range from
70 trillion cubic feet to 150 trillion cubic feet.

In
November 2009, the NEB concluded a public hearing on TransCanada's application for approval to construct and operate the Groundbirch pipeline, which is comprised
of a 77 km (48 miles) natural gas pipeline and related above-ground facilities. TransCanada has entered into firm transportation agreements with Groundbirch customers that are expected
to increase to 1.1 Bcf/d by 2014. The Groundbirch pipeline, if approved, will be an extension of the Alberta System and will connect natural gas supply primarily from the Montney shale gas
formation in northeast B.C. to existing infrastructure in northwest Alberta. Construction of the Groundbirch pipeline is expected to commence in July 2010 with completion anticipated in
November 2010. A decision from the NEB is expected in first quarter 2010. The total capital cost of the project is estimated to be $200 million.

In
May 2009, TransCanada filed a Project Description with the NEB to initiate a regulatory review of the proposed Horn River project, which comprises construction of
a 72 km (45 miles) natural gas pipeline and related facilities, including above-ground facilities, and acquisition of the existing 83 km (52 miles) Ekwan pipeline from
EnCana Corporation. The Horn River project would connect new shale natural gas supply in the Horn River basin north of Fort Nelson, B.C. to the Alberta System. Total contractual commitments for Horn
River have increased to 503 million cubic feet per day (mmcf/d) by 2014 from 378 mmcf/d as a result of newly contracted volumes from a recently announced natural gas processing
facility that will be located in the Horn River area. As part of the Horn River project, in November 2009, TransCanada entered into an agreement to acquire the Ekwan pipeline, which is expected
to close in September 2011. In February 2010, the Company filed an application with the NEB for approval to construct and operate the Horn River project. Subject to regulatory approvals, the
Horn River project is anticipated to commence operations in second quarter 2012. The total capital cost of the project is expected to be approximately $310 million.

Both
the Groundbirch and Horn River projects are proposed as extensions to the Alberta System, which would provide B.C. producers with direct integrated gas transmission
service from receipt points in B.C. These pipeline projects would also increase netbacks to producers and throughput on the Alberta System and increase usage of the Nova Inventory Transfer commercial
hub that is used by buyers and sellers of natural gas throughout North America.

NOVA
Gas Transmission Ltd. (NGTL) and Canadian Utilities Limited (ATCO Pipelines) continue to work towards obtaining the necessary regulatory approvals to provide commercial
and operational integrated services to shippers on the Alberta System and the ATCO Pipelines system in Alberta. Final decisions from the AUC and NEB are expected by mid-2010

MANAGEMENT'S DISCUSSION AND ANALYSIS27

with
implementation occurring within 12 months following receipt of required regulatory approvals. The integration of commercial and operational services on the Alberta System and ATCO
Pipelines system will create the effect of a single integrated natural gas transmission system in Alberta, resulting in more efficient transportation of natural gas for customers.

During
2009, TransCanada negotiated an Alberta System Rate Design Settlement with all key stakeholders. This rate design addresses the evolving nature of the Alberta System
and the commercial and operational integration of ATCO Pipelines. It also incorporates a single delivery service for all delivery points resulting from the amalgamation of the current intra-Alberta
and export delivery services. The changes are expected to improve the Alberta System's services by making them more consistent and adding flexibility for customers. The Company filed a
combination application with the NEB on November 27, 2009 for approval of both the Rate Design Settlement and the integration of commercial and operational services on the Alberta System and
ATCO Pipelines' system in Alberta. A final decision is expected from the NEB by mid-2010 with implementation occurring within the 12 months following approval.

TQMIn March 2009, TQM received the NEB's decision on its cost of capital application for 2007 and 2008,
which requested an 11 per cent return on 40 per cent deemed common equity. The NEB set a 6.4 per cent ATWACC for each of the two years, which equates to a
9.85 per cent return on 40 per cent deemed common equity in 2007 and a 9.75 per cent return on 40 per cent deemed common equity in 2008. Prior
to the decision, TQM was subject to the NEB ROE formula of 8.46 per cent and 8.71 per cent for 2007 and 2008, respectively, on deemed common equity of
30 per cent. In June 2009, the NEB approved TQM's final tolls for 2007 and 2008, which reflected the 6.4 per cent ATWACC.

Ventures LPIn May 2009, the AUC concluded an investigation of the rates on Ventures LP and
determined they are unjust and unreasonable. The AUC sought an Order in Council from the Alberta government to proceed with a process to establish new rates. In September 2009, the Alberta
Court of Appeal granted Ventures LP leave to appeal the AUC's decision. The appeal is expected to be heard in March 2010.

ANRIn 2009, ANR received regulatory approval of the Wisconsin 2009 Project to construct a pipeline with
capacity of approximately 97 mmcf/d that will deliver incremental natural gas to Wisconsin markets. A portion of the pipeline was placed in service in 2009. The remainder of the project is
expected to be completed in 2010.

In
2009, four new interstate pipelines made supply interconnections with ANR's southeast leg, comprising a combined interconnect capacity of 1.5 Bcf/d. The
interconnections increased ANR's access to natural gas supply from the mid-continent shale and Rocky Mountain regions, and from a Gulf Coast LNG regassification terminal.

In
September 2008, certain portions of ANR's Gulf of Mexico offshore facilities were damaged by Hurricane Ike. The Company estimates its total exposure to damage
costs to be approximately US$30 million to US$40 million, mainly to replace, repair and abandon capital assets, including the estimated cost to abandon an offshore platform. At
December 31, 2009, related capital expenditures of US$11 million (2008  US$2 million) and OM&A costs of US$7 million
(2008  US$6 million) had been incurred. The remaining costs are expected to be incurred in 2010 and 2011, with the majority to be incurred in 2011.
Service on the offshore facilities has been restored and related throughput volumes have returned to pre-hurricane levels.

PortlandIn April 2008, Portland filed a general rate case with the FERC proposing a rate increase of
approximately six per cent as well as other changes to its tariff. In May 2009, Portland reached a settlement with its customers on certain short-term issues in its rate
case. The partial settlement was filed with the FERC for approval and a decision is expected in 2010. The remaining issues were litigated and Portland received the Initial Decision from the
Administrative Law Judge in December 2009. Participants in the rate case have an opportunity
to respond to the Initial Decision. The FERC is expected to issue its final decision on the litigated portion of the rate case in fourth quarter 2010.

28MANAGEMENT'S DISCUSSION AND ANALYSIS

PipeLines LP/North BajaOn July 1, 2009, TransCanada sold North Baja to PipeLines LP. As
part of the transaction, TransCanada agreed to amend its incentive distribution rights with PipeLines LP. Under the amendment, TransCanada received additional common units in exchange for a
resetting of its incentive distribution rights at a lower percentage which escalates with increases in PipeLines LP's distributions. TransCanada received aggregate consideration totalling
approximately US$395 million from PipeLines LP, including US$200 million in cash and 6,371,680 common units of PipeLines LP. TransCanada's ownership in
PipeLines LP increased to 42.6 per cent as a result of this transaction and TransCanada continues to operate North Baja. TransCanada's ownership in PipeLines LP was reduced
to 38.2 per cent in November 2009 after PipeLines LP's public issuance of common units.

Great LakesIn November 2009, the FERC initiated an investigation to determine whether Great Lakes' rates
are just and reasonable. In response, Great Lakes filed a cost and revenue study with the FERC on February 4, 2010. A hearing is scheduled to commence on August 2, 2010, and an Initial
Decision is required in November 2010. The impact of the investigation on Great Lakes' rates and revenues is unknown at this time.

PalomarIn December 2008, Palomar Gas Transmission LLC applied to the FERC for a certificate to
build a 349 km (217 miles) natural gas pipeline extending from GTN in central Oregon, to the Columbia River northwest of Portland. The proposed pipeline has a capacity of up to
1.3 Bcf/d of natural gas. The project is a 50/50 joint venture between GTN and Northwest Natural Gas Co. Palomar is currently in discussions with potential shippers to secure
shipping commitments for the project.

GuadalajaraIn May 2009, TransCanada entered into a contract to build, own and operate a
US$320 million pipeline in Mexico, which is supported by a 25 year contract for its entire capacity with the Comisión Federal de Electricidad, Mexico's state-owned electric power
company. The Guadalajara pipeline project is a proposed natural gas pipeline of approximately 305 km (190 miles) extending from Manzanillo to Guadalajara. Regulatory approvals were
received in December 2009 and construction is underway with an expected in-service date of first quarter 2011.

U.S. Rockies Pipeline ProjectsThe Bison project is a 487 km (303 miles) proposed natural
gas pipeline from the Powder River Basin in Wyoming connecting to Northern Border in North Dakota. The FERC issued a Final Environmental Impact Statement in December 2009 and the project is in
the final stages of the regulatory approval process. The Company expects to commence construction in May 2010. The pipeline has shipping commitments for approximately 407 mmcf/d and is
expected to be placed in service in fourth quarter 2010. The capital cost of the Bison pipeline project is estimated to be US$600 million.

Previously,
TransCanada was working to develop the Pathfinder and Sunstone pipeline projects, which were proposed to deliver natural gas from the Rocky Mountains to various
U.S. markets. Based on market conditions, TransCanada has elected to consolidate its Rocky Mountain development plans and will pursue additional development opportunities using the Bison
pipeline as a platform for medium-term growth.

Alaska Pipeline ProjectIn November 2007, TransCanada submitted an application to the State of Alaska for
a license to construct the Alaska pipeline project under theAlaska Gasline Inducement Act(AGIA). In January 2008, the State of Alaska
determined that TransCanada's application was the only proposal that met all of the state's requirements and the AGIA license was issued to TransCanada in December 2008. Under the AGIA, the
State of Alaska has agreed to reimburse a share of TransCanada's eligible pre-construction costs, as they are incurred, and approved by the state to a maximum of US$500 million.

In
June 2009, TransCanada entered into an agreement with ExxonMobil to jointly advance the project. A joint project team is developing the engineering, environmental,
aboriginal relations and commercial work.

The
proposed Alaska pipeline project is a 4.5 Bcf/d natural gas pipeline extending 2,737 km (1,700 miles) from a new natural gas treatment plant at
Prudhoe Bay, Alaska to Alberta. This pipeline will provide access to diverse markets across

MANAGEMENT'S DISCUSSION AND ANALYSIS29

North
America and is expected to have an estimated capital cost of US$32 billion to US$41 billion. The pipeline construction application included provisions to expand capacity up to
5.9 Bcf/d through the addition of compressor stations in Alaska and Canada. The current estimated capital cost for the project is an increase over previously stated estimates. The latest
estimate is based on increased costs for oil and gas projects from 2007 to 2009 and a significant increase in the estimated cost of building the gas treatment plant at Prudhoe Bay. TransCanada
also proposed an alternate pipeline from Prudhoe Bay to Valdez, Alaska to supply LNG markets with an estimated capital cost of US$20 billion to US$26 billion.

On
January 29, 2010, the Alaska pipeline project filed to obtain FERC approval to conduct an open season. If approval is granted, an open season offering is expected
to be provided to potential shippers at the end of April 2010 for their assessment until July 2010. Both project options will be offered to shippers as alternative projects and both
options have an expected in-service date of 2020. TransCanada is continuing to work with potential shippers for the initial open season.

Mackenzie Gas Pipeline ProjectThe MGP is a proposed 1,200 km (746 miles) natural gas pipeline
extending from a point near Inuvik, Northwest Territories to the northern border of Alberta, where it will connect to the Alberta System.

TransCanada's
involvement with the MGP arises from a 2003 agreement between the Mackenzie Valley Aboriginal Pipeline Group (APG) and the MGP, whereby TransCanada agreed to
finance the APG's one-third share of the pre-development costs associated with the project. These costs, on a cumulative basis, are currently forecast to be between
$150 million and $200 million. Under the terms of certain MGP agreements, TransCanada holds an option to acquire up to a five per cent equity ownership in the MGP at the time of
the decision to construct it. In addition, TransCanada gains certain rights of first refusal to acquire 50 per cent of any divestitures by existing partners and an entitlement to obtain
a one-third interest in all expansion opportunities once the APG reaches a one-third ownership share, with the other natural gas pipeline owners and the APG sharing
the balance.

Cumulative
advances to the APG by TransCanada totalled $143 million at December 31, 2009 (2008  $140 million) and
are included in intangibles and other assets. These advances constitute a loan to the APG, which becomes repayable only after the natural gas pipeline commences commercial operations. The total amount
of the loan is expected to form part of the rate base of the pipeline and to be repaid from the APG's share of future natural gas pipeline revenues or from alternate financing. If the project does not
proceed, TransCanada has no recourse against the APG for recovery of advances made.

TransCanada
and the other co-venture companies involved in the MGP continue to pursue approval of the proposed project, focusing on obtaining regulatory approval
and the Canadian government's support of an acceptable fiscal framework. The regulatory process reached a milestone in late December 2009 with the release of the Joint Review Panel's report on
environmental and socio-economic factors relating to the project. The report has been submitted to the NEB as part of the review process required for approval of the project. The NEB review is
scheduled to conclude with final arguments in April 2010. A decision by the NEB is currently expected by fourth quarter 2010. Project timing continues to be uncertain. In the event the
co-venture group is unable to reach an agreement with the government on an acceptable fiscal framework, the parties will need to determine the appropriate next steps for the project. For
TransCanada, this may result in a reassessment of the carrying amount of the APG advances.

PIPELINES  BUSINESS RISKS

Natural Gas Supply, Markets and CompetitionTransCanada faces competition at both the supply and market ends of its
natural gas pipelines systems. This competition comes from other natural gas pipelines accessing the increasingly mature WCSB and markets served by TransCanada's pipelines as well as from natural gas
supplies produced in basins not directly served by the Company. Growth in supply and pipeline infrastructure has increased competition throughout

30MANAGEMENT'S DISCUSSION AND ANALYSIS

---



North
America. Production in the U.S. has increased, driven primarily by shale gas, while WCSB production has declined. The lower cost shale gas in the U.S. has resulted in an increase in
competition between supply basins, changes to traditional flow patterns and an increase in choices for customers. This change has contributed to a continued reduction in long-term firm contracted
capacity and a shift to short-term firm and interruptible contracts.

Although
TransCanada has diversified its natural gas supply sources through recent pipeline acquisitions, many of its North American natural gas pipelines and its
transmission infrastructure remain dependent on supply from the WCSB. The WCSB has established natural gas reserves of approximately 61 trillion cubic feet and a
reserves-to-production ratio of approximately 11 years at current levels of production. Supply from the WCSB has declined in recent years due to a continued reduction in
drilling activity in the basin. The reduced drilling activity is a result of lower prices, higher supply costs, which include increased royalties in Alberta, and competition for capital from other
North American gas production basins that have lower exploration costs. Drilling levels in the WCSB are expected to recover in the future, assuming natural gas prices stabilize and finding and
development costs become more economical. TransCanada expects there will be excess natural gas pipeline capacity from the WCSB for the foreseeable future as a result of capacity expansions on its
natural gas pipelines over the past decade, competition from other pipelines, and significant growth in natural gas consumption within Alberta driven by oilsands and electricity generation
requirements.

TransCanada's
Alberta System is the major natural gas gathering and transportation system for the WCSB, connecting most of the natural gas processing plants in Alberta to
domestic and export markets. Despite reduced overall drilling levels, activity remains robust in certain areas of the WCSB, which has resulted in the need for new transmission infrastructure. Drilling
activity has increased in northwestern Alberta, near Grande Prairie, and in northeastern B.C., near Dawson Creek, as producers develop projects to access multi-zone reserves with deeper
wells and to access unconventional shale gas utilizing horizontally drilled wells. Recently, shale gas production in B.C. has emerged as a potentially significant natural gas supply source.
TransCanada currently forecasts 3.5 Bcf/d total production from the Montney and Horn River shale gas sources by 2020. TransCanada is currently pursuing two major extensions of its Alberta
System that would allow emergent unconventional B.C. gas production from the Montney and Horn River shale gas plays to be transported to markets served by TransCanada's pipeline systems.

Demand
for natural gas in Eastern Canada and the U.S. Northeast decreased in 2009 largely as a result of a reduction in industrial demand caused by the global
recession. However, future demand for natural gas in TransCanada's key eastern markets, which are served by the Canadian Mainline, is expected to increase over time, particularly to meet the expected
growth in natural gas-fired power generation. Although there are opportunities to increase market share in Canadian domestic and U.S. export markets, TransCanada faces significant
competition in these markets. Consumers in the northeastern U.S. generally have access to an array of natural gas pipeline and supply options. Eastern markets that historically received
Canadian supplies only from TransCanada's systems are now able to receive supplies from new natural gas pipelines that source U.S. and Atlantic Canada supplies. In recent years, the Canadian Mainline
has experienced reductions in volumes originating at the Alberta border and in Saskatchewan, which have been partially offset by increases in volumes originating at points east of Saskatchewan. These
net volume reductions have resulted in an increase in Canadian Mainline tolls that adversely affects its competitive position.

ANR's
directly connected natural gas supply is primarily sourced from the Gulf of Mexico and mid-continent U.S. regions, which are also served by
competing natural gas pipelines. The Gulf of Mexico region is highly competitive given its extensive natural gas pipeline network. ANR is one of many interstate and intrastate pipelines competing for
new and existing production as well as for new supplies from pipelines originating in the mid-continent shale and Rocky Mountain production regions, and from new and existing Gulf Coast
LNG regassification terminals. ANR has competition from other natural gas pipelines and storage operations in its primary markets in the U.S. Midwest. In addition to pipeline competition for
market and supply, difficult economic conditions have reduced natural gas demand and may put future ANR capacity renewals at risk. As lower natural gas prices reduce drilling activity, the supply
growth that has been fuelling the expansion of pipeline infrastructure in the mid-continent could slow down but is still

MANAGEMENT'S DISCUSSION AND ANALYSIS31

---



expected
to exceed demand requirements in the near term. These factors could negatively affect the value of pipeline capacity as transportation capacity becomes more abundant.

ANR's
natural gas storage is primarily contracted on a short-term basis of three to five years. Storage is recontracted based on current market conditions, which may become
unfavourable and result in reduced rates and terms.

GTN
must compete with other pipelines to access natural gas supplies and markets. Transportation service capacity on GTN provides customers in the U.S. Pacific
Northwest, California and Nevada with access to supplies of natural gas primarily from the WCSB. These three markets may also access supplies from other basins. In the Pacific Northwest market,
natural gas transported on GTN competes with the Rocky Mountain natural gas supply and with additional Western Canadian supply transported by other pipelines. Historically, natural gas supplies from
the WCSB have been competitively priced in relation to supplies from the other regions serving these markets. Recently, low natural gas prices have reduced drilling and production in the WCSB
resulting in increased competition for supply which could negatively impact transportation value on GTN. Pacific Gas and Electric Company, GTN's largest customer, has received California Public
Utilities Commission approval to commit to capacity on a proposed competing project out of the Rocky Mountain basin to the California border.

Crude Oil Supply, Markets and CompetitionAlberta is the primary source of crude oil supply for Keystone,
producing approximately 79 per cent of the oil in the WCSB. In 2009, the WCSB produced an estimated 2.5 million Bbl/d, comprised of 1.1 million Bbl/d of conventional crude
oil and condensate, and 1.4 million Bbl/d of crude oil from Alberta's oilsands. The production of conventional crude oil has been declining but has been offset by increases in production from
the Alberta oilsands. The Alberta Energy Resources Conservation Board estimated in its June 2009 report that there are approximately 170 billion barrels of remaining established reserves
in the Alberta oilsands.

In
June 2009, the Canadian Association of Petroleum Producers forecasted WCSB crude oil supply would increase to 3.3 million Bbl/d by 2015 and to
3.9 million Bbl/d by 2020 from 2.4 million Bbl/d in 2008. In first quarter 2010, crude oil producers announced plans to undertake approximately $8 billion of new oilsands
projects, indicating future growth in Alberta oilsands production.

Keystone
currently has contracted a significant portion of its capacity. Keystone will compete for spot market throughput with other crude oil pipelines from Alberta and for
new long-term contracts as supply from the WCSB increases.

Keystone's
markets for crude oil are refiners in the U.S. Midwest and Gulf Coast regions. Keystone will compete with pipelines that deliver WCSB crude oil to these
markets through interconnections with other pipelines. Keystone will also compete with U.S. domestically produced crude oil and imported crude oil for markets in the U.S. Midwest and
Gulf Coast regions.

Regulatory Financial RiskRegulatory decisions continue to have a significant impact on the financial returns
from existing investments in TransCanada's Canadian pipelines and are expected to have a similarly significant impact on financial returns from future investments. Through rate applications and
negotiated settlements, TransCanada has been able to improve the financial returns of its Canadian pipeline capital structures.

Regulations
and decisions by regulatory bodies, particularly those issued in the U.S. by the FERC, Environmental Protection Agency and Department of Transportation,
may have a significant impact on the financial returns from TransCanada's existing investments in U.S. pipelines. TransCanada continually monitors existing and proposed regulations to determine
the possible impact on its U.S. pipelines.

Throughput RiskAs transportation contracts expire, TransCanada's U.S. natural gas pipelines are expected
to become more exposed to the risk of reduced throughput and their revenues are more likely to experience increased variability.

32MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Throughput
risk is created by supply and market competition, economic activity, weather variability, natural gas pipeline competition and pricing of alternative fuels.

Execution and Capital Cost RiskCapital costs related to the construction of Keystone are subject to a capital
cost risk- and reward-sharing mechanism with TransCanada's customers. This mechanism allows Keystone to adjust its tolls by a factor based on the percentage change in the capital cost of
the project. Tolls for the portion of Keystone to Wood River, Patoka and Cushing will be adjusted by a factor equal to 50 per cent of the percentage change in capital cost. Tolls on the
expansion to the Gulf Coast would be adjusted by a factor equal to 75 per cent of the percentage change in capital cost.

PIPELINES  OUTLOOK

Although demand for natural gas and crude oil has declined and is expected to remain relatively weak in North America in 2010 due to the current economic conditions, the
Company expects demand to increase in the long term. TransCanada's Pipelines business will continue to focus on the delivery of natural gas and crude oil to growing markets, connecting new supply and
progressing development of new infrastructure to connect natural gas from the north and unconventional supplies such as shale gas, coalbed methane and LNG.

Reduced
throughput and greater use of shorter distance transportation contracts are the primary factors contributing to an increase in the Canadian Mainline's toll of
approximately 40 per cent in 2010 from 2009. This situation, coupled with the ongoing development and growth of competitive alternative natural gas supply and infrastructure from
U.S. shale gas regions, is increasing competitive pressures on the Canadian Mainline. In response, TransCanada has initiated a process to examine the Canadian Mainline's rate design, business
model and available services to develop solutions that would result in higher throughput and revenue as well as lower costs and tolls. TransCanada is also pursuing the connection of new sources of
U.S. gas supply to the existing Canadian Mainline infrastructure to maintain its current markets and competitive position.

Most
of TransCanada's expansion plans in Canadian natural gas transmission are focused on the Alberta System. TransCanada is actively involved in expanding the Alberta
System to serve the growing shale gas regions in northeastern B.C. Additional growth opportunities for the Alberta System include the west and central foothills regions of Alberta.

In
the U.S., TransCanada expects unconventional production will continue to be developed from shale gas reservoirs in east Texas, northwest Louisiana, Arkansas, southwest
Oklahoma and the Appalachian Mountain region. Supplies from coalbed methane and tight gas sands in the Rocky Mountain region are also expected to grow. Additionally, in the medium to long term, some
level of incremental supply is anticipated from LNG imports into the U.S., particularly in the summer months. The resulting growth in U.S. supply is expected to provide additional opportunities
for TransCanada. In particular, the southwest leg of ANR is expected to continue to remain fully subscribed for the foreseeable future and new transport routes are being developed to move additional
Rocky Mountain and shale gas production to mid-western and eastern U.S. markets, including interconnections with ANR. The southeast leg of ANR is well positioned and has capacity to
transport additional volumes of unconventional and Rocky Mountain natural gas production as well as LNG.

Producers
continue to develop new crude oil supply in Western Canada. Several Alberta oilsands projects recently completed or under construction will begin to produce oil or
will increase crude oil production in 2010 and 2011. Oilsands production is forecast to increase to 2.2 million Bbl/d by 2015 from 1.2 million Bbl/d in 2008 and total Western Canada
crude oil supply is projected to grow over the same period to 3.3 million Bbl/d from 2.4 million Bbl/d. Most of this growth is in heavy crude oil supply. The primary market for new crude
oil production extends from the

MANAGEMENT'S DISCUSSION AND ANALYSIS33

---



U.S. Midwest
to the Gulf Coast and contains a large number of refineries that are well equipped to handle Canadian light and heavy crude oil blends. Incremental western Canadian crude oil
production is expected to replace declining U.S. imports of crude oil from other countries.

The
increase in WCSB crude oil exports from Alberta requires access to new markets, including the Gulf Coast. TransCanada will continue to pursue additional opportunities to
move crude oil from Alberta to U.S. markets.

TransCanada
will continue to focus on operational excellence and collaboration with all stakeholders to achieve negotiated settlements and provision of services that will
increase the value of the Company's business.

EarningsThe Company expects continued growth on its Alberta System. TransCanada also anticipates a modest level
of investment in its other Canadian natural gas pipelines but expects a continued net decline in the average investment bases of these pipelines due to annual depreciation. A net decline in the
average investment base has the effect of reducing year-over-year earnings from these assets. Under the current regulatory model, earnings from Canadian pipelines are not
affected by short-term fluctuations in the commodity price of natural gas, changes in throughput volumes or changes in contract levels. In addition, Pipelines' EBITDA is expected to be
affected by costs to develop new pipeline projects, including the Alaska pipeline project.

Reduced
firm transportation contract volumes due to customer defaults, lower supply available for export from the WCSB and expiry of long-term contracts could
have a negative impact on short-term earnings from TransCanada's U.S. natural gas pipelines, unless the available capacity can be recontracted. The ability to recontract available
capacity is influenced by prevailing market conditions and competitive factors, including competing natural gas pipelines and supply from other natural gas sources in markets served by TransCanada's
U.S. pipelines. EBITDA from Pipelines' foreign operations is also impacted by changes in foreign currency exchange rates.

EBITDA
from Keystone is expected to commence in 2010 and continue to increase over the short term until all phases of Keystone are fully operational in 2013. Refer to the
Pipelines  Opportunities and Developments section of this MD&A for further information on Keystone's expected EBITDA.

Capital ExpendituresTotal capital spending for all pipelines in 2009 was $3.9 billion. Capital spending
for the wholly owned pipelines in 2010, including Keystone, is expected to be approximately $4.7 billion.

|GRAPHIC |  | Energy's comparable EBIT was $784 million in 2009 compared to $952 million in 2008. Comparable EBIT excluded net unrealized gains of $1 million and nil in 2009 and 2008, respectively, resulting from changes in the fair value of
proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts. Comparable EBIT in 2008 excluded the $41 million writedown of costs previously capitalized for the Broadwater LNG project.
Energy's comparable EBIT in 2008 of $952 million increased $224 million compared to $728 million in 2007. Comparable EBIT in 2007 excluded a $16 million gain on sale of land and $10 million of net unrealized gains resulting
from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts.

ENERGY  FINANCIAL ANALYSIS

Western PowerAs at December 31, 2009, Western Power owned or had the rights to approximately
2,600 MW of power supply in Alberta and the Western U.S. from its three long-term PPAs, five natural gas-fired cogeneration facilities and a simple-cycle, natural
gas peaking facility under construction in Arizona. The current operating power supply portfolio of Western Power in Alberta comprises approximately 1,700 MW of low-cost,
base-load coal-fired generation supply through the three long-term PPAs and approximately 400 MW of natural gas-fired cogeneration assets. This
supply portfolio includes some of the lowest cost, most competitive generation in the Alberta market area. The Sheerness and Sundance B PPAs expire in 2020, while the Sundance A PPA expires in 2017.
Plant operations in Alberta consist of five natural gas-fired cogeneration power plants ranging from 27 MW to 165 MW per facility. A portion of the expected output from these
facilities is sold under long-term contracts and the remaining output is subject to fluctuations in the price of power and natural gas.

Western
Power relies on its two integrated functions, marketing and plant operations, to generate earnings. The marketing function, based in Calgary, Alberta, purchases and
resells electricity sourced through the PPAs, markets uncommitted volumes from the cogeneration facilities, and purchases and resells power and natural gas to maximize the value of the cogeneration
facilities. The marketing function is critical for optimizing Energy's return from its portfolio of power supply and managing risks associated with uncontracted volumes. A portion of Energy's power is
sold into the spot market to ensure supply in case of unexpected plant outages. The overall amount of spot market volumes is dependent upon the ability to transact in forward sales markets at
acceptable contract terms. This approach to portfolio management helps to minimize costs in situations where TransCanada would otherwise have to
purchase electricity in the open market to fulfil its contractual sales obligations. To reduce exposure to spot market prices on uncontracted volumes, as at December 31, 2009, Western Power had
fixed-price power sales contracts to sell approximately 8,400 gigawatt hours (GWh) in 2010 and 6,000 GWh in 2011.

Eastern PowerEastern Power owns approximately 2,900 MW of power generation capacity, including
facilities under construction or in the development phase. Eastern Power's current operating power generation assets are Bécancour, three Cartier Wind farms, Portlands Energy
and Grandview.

Bécancour's
entire power output is supplied to Hydro-Québec under a 20 year power purchase contract expiring in 2026. Steam from this
facility is sold to an industrial customer for use in commercial processes. Electricity generation at the Bécancour power plant has been temporarily suspended since January 2008
due to an agreement entered into with Hydro-Québec. Under the agreement TransCanada continues to receive payments similar to those that would have been received under the normal course
of operation. The suspension of the Bécancour power facility is discussed further in the Energy  Opportunities and Developments section of
this MD&A.

Cartier
Wind's three wind farms, Carleton, Anse-à-Valleau, and Baie-des-Sables, were placed into service in
November 2008, November 2007 and November 2006, respectively. Output from these wind farms is supplied to Hydro-Québec under 20 year power purchase
contracts.

40MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Portlands
Energy was placed into service in April 2009. This facility provides power under a 20 year Accelerated Clean Energy Supply contract with
the OPA.

Grandview
is located on the site of the Irving oil refinery in Saint John, New Brunswick. Irving is under a 20 year tolling arrangement, which expires in 2025,
to supply fuel for the plant and to contract 100 per cent of the 90 MW plant's heat and electricity output.

Eastern
Power is focused on selling power under long-term contracts. In 2007, 2008 and 2009, all of Eastern Power sales volumes were sold under contract and are
expected to continue to be 100 per cent sold under contract for 2010 and 2011.

Western Power's comparable EBITDA of $279 million in 2009 decreased $231 million compared to $510 million in
2008. The decrease was primarily due to a decline in earnings from the Alberta power portfolio resulting from lower overall realized prices on reduced volumes of power sold. In addition, Western
Power's EBITDA in 2008 included $23 million related to sulphur sales.

Lower
overall realized power prices and lower sales volumes resulted in a decrease of $352 million in Western Power's power revenues in 2009 compared to 2008. Average
spot market power prices in Alberta decreased 47 per cent, or $42 per megawatt hour (MWh) in 2009 compared to 2008 and Western Power's sales volumes decreased 13 per cent
in 2009 from 2008 primarily as a result of reduced dispatch of the Alberta PPAs. The reduction in power prices and sales volumes both reflected reduced demand for electricity in Alberta as a result of
the North American economic downturn. Commodity purchases resold of $451 million in 2009 decreased $66 million compared to 2008 due to a reduction in volumes purchased and the expiry of
certain retail contracts. Approximately 26 per cent of Western Power's sales volumes were sold in the spot market in 2009 compared to 27 per cent in 2008.

Eastern
Power's comparable EBITDA of $220 million in 2009 increased $73 million compared to $147 million in 2008. The increase was primarily due to
incremental earnings from Portlands Energy, which was placed in service in April 2009, and the Carleton wind farm at Cartier Wind, which went into service in November 2008, as well as
higher contracted revenue from the Bécancour facility. Eastern Power's power revenues increased $106 million primarily due to the incremental revenues from Portlands Energy and
the Carleton wind farm.

42MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Other
revenues and other commodity purchases resold were $184 million and $124 million, respectively, in 2009 compared to $186 million and
$112 million, respectively, in 2008. These changes reflected an increase in the quantity of natural gas being resold in Eastern Power. Increased sales of natural gas in other revenues in 2009
were more than offset by the sale of sulphur in 2008.

Plant
operating costs and other, which includes fuel gas consumed in power generation, of $179 million in 2009 decreased $36 million from 2008 primarily due to
lower prices for natural gas in Western Power, partially offset by incremental fuel consumed at Portlands Energy.

Western
Power's comparable EBITDA was $510 million in 2008, an increase of $125 million from $385 million in 2007. The increase was primarily due to
increased margins from a combination of higher overall realized power prices on uncontracted volumes of power sold and a $23 million increase from sales of sulphur at significantly higher
prices in 2008. In 2008, the Company sold the remainder of its sulphur stock pile, which it had been selling in modest quantities on a break-even basis since 2005.

Western
Power's power revenues increased $95 million in 2008 compared to 2007 primarily due to the higher overall power sales prices. Commodity purchases resold
decreased $33 million in 2008 compared to 2007 primarily due to a decrease in volumes purchased and the expiry of certain retail contracts. Purchased power volumes in 2008 decreased from 2007
primarily due to the expiry of certain retail contracts, partially offset by increased utilization from the Alberta PPAs. Approximately 27 per cent of power sales volumes were sold in
the spot market in 2008 compared to 24 per cent in 2007.

Eastern
Power's comparable EBITDA of $147 million in 2008 increased $27 million compared to 2007 as a result of higher contracted earnings from the
Bécancour facility, incremental earnings from the first full year of operations from the Anse-à-Valleau wind farm and the start up of the Carleton
wind farm in 2008.

The
agreement to temporarily suspend generation at the Bécancour facility beginning January 2008 resulted in decreases to Eastern Power's power
revenues, generation volumes and contracted sales as well as plant operating costs and other in 2008 compared to 2007.

Decreases
in plant operating costs and other in 2008 compared to 2007 due to the temporary suspension of the Bécancour facility were partially offset by
higher volumes of gas purchased at higher prices in Western Power.

Western
Power's plants operated with an average availability of approximately 93 per cent in 2009 compared to 87 per cent in 2008, primarily due
to the return to service of the Cancarb facility in April 2009. Western Power's overall plant availability was negatively affected from late 2007 until April 2009 by an outage at the
Cancarb power plant. Eastern Power achieved plant availability of 97 per cent in 2009, consistent with 2008 and 2007. Bécancour, which had an availability of
97 per cent in 2007, is not included in Eastern Power's 2009 and 2008 measurement as power generation from the plant was suspended throughout 2008 and 2009.

Bruce PowerBruce Power is a nuclear power generation facility located northwest of Toronto, Ontario and is
comprised of Bruce A and Bruce B. Bruce A has four 750 MW reactors, of which two are currently
operating and two are being refurbished. One unit is expected to be restarted in mid-2011 and the other unit is expected to be restarted approximately four months thereafter.
Bruce B has four operating reactors with a combined capacity of 3,200 MW. As at December 31, 2009, TransCanada and BPC Generation Infrastructure Trust (BPC), a trust established
by the Ontario Municipal Employees Retirement System (OMERS), each owned a 48.8 per cent interest in Bruce A
(2008  48.9 per cent; 2007  48.7 per cent). The remaining 2.4 per cent interest
in Bruce A is owned by the Power Workers' Union Trust (PWU), the Society of Energy Professionals Trust (SEP) and Bruce Power Employee Investment Trust. The Bruce A partnership subleases
Bruce A Units 1 to 4 from the Bruce B partnership. TransCanada, OMERS and Cameco Corporation each own 31.6 per cent of Bruce B, which consists of Units 5 to 8
and the supporting site infrastructure. The remaining interest in Bruce B is owned by PWU and SEP.

TransCanada's proportionate share of Bruce Power's comparable EBITDA increased $77 million to $352 million in 2009
compared to 2008 primarily due to higher realized prices and reduced annual lease expense, partially offset by lower volumes and higher operating expenses for Bruce A.

44MANAGEMENT'S DISCUSSION AND ANALYSIS

---



TransCanada's
proportionate share of Bruce A's comparable EBITDA decreased $30 million to $48 million in 2009 compared to 2008 as a result of lower
volumes and higher operating expenses due to an increase in outage days, partially offset by higher contracted prices for output.

TransCanada's
proportionate share of Bruce B's comparable EBITDA increased $107 million to $304 million in 2009 compared to 2008 primarily due to higher
realized prices resulting from the recognition of payments received pursuant to the floor price mechanism in Bruce B's contract with the OPA and a reduction in annual lease expense. Provisions
in a lease agreement with Ontario Power Generation allowed for a reduction in annual lease expense as the annual average Ontario spot price for electricity was less than $30 per MWh. The annual
average Ontario spot price was $29.52 per MWh in 2009 compared to 48.83 per MWh in 2008.

Amounts
received under the floor price mechanism in any calendar year are subject to repayment if the annual average spot price exceeds the annual average floor price. In
2009, the annual average spot price did not exceed the annual average floor price, therefore, no amounts recorded in revenue in 2009 will be repaid. Bruce B did not recognize into revenue any
of the support payments received under the floor price mechanism in 2007 or 2008 as the annual average spot price exceeded the annual average floor price.

TransCanada's
proportionate share of Bruce Power's comparable EBITDA in 2008 increased $35 million to $275 million compared to 2007 as a result of higher
realized prices and increased volumes associated with a decrease in outage days at Bruce A in 2008.

TransCanada's
proportionate share of Bruce Power's generation in 2009 decreased to 12,661 GWh compared to 12,958 GWh in 2008, partially due to periods in 2009
when the Independent Electricity System Operator (IESO) curtailed certain units at Bruce Power to address surplus base load generation in Ontario. During these unit curtailments by the IESO, Bruce
Power received deemed generation payments at OPA contract prices. Including deemed generation, the combined average availability of Bruce A and Bruce B was 87 per cent in
2009 compared to 86 per cent in 2008. TransCanada's proportionate share of Bruce Power's generation in 2008 was consistent with 2007.

The
overall plant availability percentage in 2010 is expected to be in the mid-80s for the two operating Bruce A units and in the high 80s for the four
Bruce B units. An approximate ten week maintenance outage of Bruce A Unit 3 is scheduled to begin in late February 2010. Maintenance outages of approximately eight weeks
are scheduled to begin in May 2010 for Bruce B Unit 6 and mid-October 2010 for Bruce B Unit 5.

Bruce A

Under a contract with the OPA, all of the output from Bruce A is effectively sold at a fixed price per MWh, adjusted for inflation annually each April 1. In
addition, fuel costs are recovered from the OPA. In accordance with a 2007 contract amendment, effective April 1, 2009, the fixed price for output from Bruce A was
$64.45 per MWh.

Bruce B

As part of Bruce Power's contract with the OPA, all output from Bruce B Units 5 to 8 are subject to a floor price adjusted annually for inflation on
April 1.

|April 1, 2007  March 31, 2008 |  | $46.82 

MANAGEMENT'S DISCUSSION AND ANALYSIS45

Payments received pursuant to the Bruce B floor price mechanism were previously subject to a recapture payment dependent on annual spot prices over the entire term of
the contract. In July 2009, the contract with the OPA was amended making payments received pursuant to the floor price mechanism subject to recapture payments dependent on annual spot prices
only within each calendar year.

Bruce B
enters into fixed-price contracts under which it receives the difference between the contract price and spot price. As a result, Bruce B's 2009
realized price of $64 per MWh reflects revenues recognized from both the floor price mechanism and contract sales, compared to $57 per MWh and $52 per MWh in 2008 and 2007, respectively. As at
December 31, 2009, Bruce B had entered into fixed-price contracts to sell forward approximately 2,100 GWh for 2010 and 500 GWh for 2011, representing TransCanada's
proportionate share.

U.S. PowerU.S. Power owns approximately 3,800 MW of power generation capacity, including
facilities under construction. U.S. Power's current operating power generation assets are Ravenswood, TC Hydro, OSP, and phase one of Kibby Wind. Ravenswood, located in Queens, New York
and acquired in August 2008, is a 2,480 MW natural gas and oil-fired generating facility consisting of multiple units employing steam turbine, combined-cycle and combustion
turbine technology with the capacity to serve approximately 21 per cent of the overall peak load in New York City. The TC Hydro assets include 13 hydroelectric stations
housing a total of 39 hydroelectric generating units in New Hampshire, Vermont and Massachusetts with total generating capacity of 583 MW. OSP, a 560 MW natural
gas-fired combined-cycle facility, is the largest power plant in Rhode Island and phase one of Kibby Wind is a 66 MW wind farm located in Maine.

U.S. Power
conducts its business primarily in the deregulated New England and New York power markets through its wholly owned subsidiary, TCPM, located
in Westborough, Massachusetts. TCPM focuses on selling power under short- and long-term contracts to wholesale, commercial and industrial customers while managing a portfolio of power
supplies sourced from both its own generation and wholesale power purchases. Power is purchased to satisfy a significant portion of TCPM's retail and wholesale power sales commitments, mitigating its
exposure to fluctuations in spot market prices and effectively locking in a positive margin. Power generation is managed by entering into contracts to sell a portion of power forecasted to be
generated. Corresponding contracts are entered into simultaneously to purchase the fuel required to reduce exposure to market price volatility and lock in positive margins. In 2009, TCPM continued to
expand its marketing presence and customer base in the New England and New York markets.

The
New England Power Pool relies on a Forward Capacity Market (FCM) to promote investment in new and existing power resources needed to meet growing consumer demand
and maintain a reliable power system. FCM payments began in late 2006 and operated on a transition basis from 2007 to 2009. During this period, OSP and TC Hydro received capacity transition payments
under this mechanism as specified in the FERC-approved FCM settlement. Beginning in June 2010, the price paid for capacity will be determined by annual competitive FCM auctions,
which are held three years in advance of the capacity year in question. Future auction results will be affected by actual versus projected demand, the pace of progress in developing new qualifying
resources that bid into the auctions and other factors.

The
New York Independent System Operator (NYISO) relies on a locational capacity market intended to promote investment in new and existing power resources needed to
meet growing consumer demand and maintain a reliable power system. At present, a series of voluntary forward auctions and a mandatory spot demand curve price setting process are used to determine the
price paid to capacity suppliers. There are two annual six-month strip forward auctions and 12 monthly forward auctions in which buyer and seller participation is optional. All
remaining available capacity is required to participate in a monthly spot auction in the final week prior to the capacity month. The spot auction clears at a price based on a downward sloping demand
curve, the parameters of which are determined by the NYISO and approved by the FERC. There are separate demand curves for each of three defined capacity zones: Long Island, New York City, and
Rest of State. The Ravenswood capacity is located in the New York City capacity zone.

U.S. Power's comparable EBITDA was $192 million in 2009, $39 million lower than the $231 million earned
in 2008. The decrease was primarily due to reduced power prices and lower margins realized on generation volumes in New England, partially offset by forward hedging activities. Lower realized
prices were a result of the economic

downturn
coupled with unseasonably mild weather. These decreases were partially offset by incremental revenue realized on contract sales at higher than average spot market prices in
New England. The reduction in New England EBITDA was partially offset by incremental EBITDA from a full year of operations at the Ravenswood facility, which was acquired in
August 2008, and the positive impact of a stronger U.S. dollar in 2009. Ravenswood results in 2009 were impacted by spot prices, which were 52 per cent lower than in 2008,
and reduced power demand.

U.S. Power's
power revenues of $1,118 million in 2009, increased $180 million from $938 million in 2008 primarily due to incremental revenues
from the Ravenswood facility, the positive impact of a stronger U.S. dollar and an increase in financial contract sales, partially offset by lower volumes of power sold at lower prices in
New England. Capacity revenue of $190 million in 2009 increased $105 million from $85 million in 2008 primarily
due to incremental capacity revenue from Ravenswood, which is earned based on plant availability regardless of whether the plant is generating electricity.

Other
revenues increased $159 million in 2009 compared to 2008 as a result of higher volumes of natural gas sold, revenues earned from the third-party service
agreement at Ravenswood and the positive impact of a stronger U.S. dollar.

Power
commodity purchases resold increased $25 million in 2009 compared to 2008 primarily due to the incremental impact of financial contract purchases in
New England and the impact of a stronger U.S. dollar in 2009. These increases were partially offset by lower volumes of power purchased for resale at lower prices to commercial and
industrial customers in New England.

Other
commodity purchases resold increased $67 million in 2009 compared to 2008 primarily due to higher volumes of unutilized natural gas purchased for plant fuel and
resold as well as the impact of a stronger U.S. dollar, partially offset by a decrease in natural gas prices.

Plant
operating costs and other increased $387 million in 2009 compared to 2008 due to a full year of operations and costs related to a third-party service agreement
at Ravenswood, as well as the impact of a stronger U.S. dollar.

Comparable
EBITDA was $231 million in 2008, $79 million higher than the $152 million earned in 2007. The increase was primarily due to increased water
flows from the TC Hydro generation assets and higher realized prices on sales to commercial and industrial customers in New England. On December 31, 2008, Ravenswood fulfilled its
obligations under a tolling agreement with a third party that was in place at the time of its acquisition. Beginning in 2009, TCPM has managed the marketing output of the Ravenswood plant in a manner
consistent with its other U.S. Northeast portfolio of assets.

U.S. Power
achieved plant availability of 79 per cent in 2009 compared to 75 per cent in 2008 primarily due to the return to service of
Ravenswood Unit 30 in May 2009 following an unplanned outage. Plant availability in 2008 was 20 per cent lower than in 2007 as a result of outages experienced at
Ravenswood throughout fourth quarter 2008.

In
2009, nine per cent of power sales volumes were sold into the spot market compared to two per cent in 2008. At December 31, 2009, U.S. Power
had fixed price sales contracts to sell forward approximately 10,300 GWh in 2010 and 5,400 GWh in 2011, including financial contracts to economically hedge the price of forecasted power
generation. Certain contracted volumes are dependent on customer usage levels. Actual amounts contracted in future periods will depend on market liquidity and other factors. Power has been purchased
to satisfy a portion of these sales requirements, reducing exposure to volatility in spot prices and effectively locking in a margin.

Natural Gas StorageTransCanada owns or has rights to 129 Bcf of non-regulated natural gas
storage capacity in Alberta, including a 60 per cent ownership interest in CrossAlta, an independently operated storage facility. TransCanada also has contracts for
long-term, Alberta-based storage capacity from a third party, which expire in 2030, subject to early termination rights in 2015.

The Company's natural gas storage capability helps balance seasonal and short-term supply and demand, and adds
flexibility to the delivery of natural gas to markets in Alberta and the rest of North America. The increasing seasonal imbalance in North American natural gas supply and demand has increased natural
gas price volatility and the demand for storage services. Alberta-based storage will continue to serve market needs and could play an important role as additional gas supplies are connected to North
American markets. Energy's natural gas storage business operates independently from TransCanada's regulated natural gas transmission business and from ANR's regulated storage business, which is
included in TransCanada's Pipelines segment.

TransCanada
manages the exposure of its non-regulated natural gas storage assets to seasonal natural gas price spreads by economically hedging storage capacity
with a portfolio of third-party storage capacity contracts and proprietary natural gas purchases and sales.

Market
volatility creates arbitrage opportunities and TransCanada's storage facilities provide customers with the ability to capture value from short-term price
movements. At December 31, 2009, TransCanada had contracted approximately 75 per cent of the total 129 Bcf of working gas storage capacity in 2010 and
51 per cent of storage capacity in 2011. Earnings from third-party storage capacity contracts are recognized over the terms of the contracts.

Proprietary
natural gas storage transactions are comprised of a forward purchase of natural gas to be injected into storage and a simultaneous forward sale of natural gas
for withdrawal at a later period, typically during the winter withdrawal season. By matching purchase and sales volumes on a back-to-back basis, TransCanada locks in future
positive margins, effectively eliminating its exposure to natural gas seasonal price spreads.

These
forward natural gas contracts provide highly effective economic hedges but do not meet the specific criteria for hedge accounting and, therefore, are recorded at their
fair value based on the forward market prices for the contracted month of delivery. Changes in the fair value of these contracts are recorded in revenues. TransCanada records its proprietary natural
gas inventory in storage at its fair value using a weighted average of forward prices for natural gas for the following four months, less selling costs. Changes in the fair value of inventory are
recorded in revenues. Changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sales contracts are excluded in determining comparable earnings, as
they are not representative of amounts that will be realized on settlement.

Natural
Gas Storage's comparable EBITDA in 2009 was $164 million compared to $138 million in 2008. The $26 million increase in EBITDA was primarily due
to increased third-party storage revenues as a result of higher realized seasonal natural gas price spreads. Natural Gas Storage's comparable EBITDA was $138 million in 2008 which was
consistent with 2007.

Business DevelopmentBusiness development comparable EBITDA losses in 2009 decreased $15 million compared
to 2008 primarily due to the timing of expenses on certain key projects.

MANAGEMENT'S DISCUSSION AND ANALYSIS49

---



Depreciation and AmortizationDepreciation and amortization of $347 million in 2009 increased
$89 million compared to 2008 primarily due to a full year of operations at Ravenswood, capital additions at Bruce Power and the start-up of Portlands Energy and the Carleton wind farm in
April 2009 and November 2008, respectively.

ENERGY  OPPORTUNITIES AND DEVELOPMENTS

RavenswoodFrom the time of its acquisition to December 31, 2008, Ravenswood operated under a tolling
arrangement under which all energy generated from the facility was provided to a third party for a fixed operating fee. In January 2009, Ravenswood commenced earning revenues from the sale of
energy generated from the facility into the New York market. TCPM manages the marketing of output from Ravenswood.

Subsequent
to closing the acquisition of Ravenswood, TransCanada experienced a forced outage event related to Ravenswood's 972 MW Unit 30. The unit returned to
service in May 2009. The Company continues to work with its insurers with respect to claims for both the physical damage and business interruption losses associated with the outage. No
amounts have been accrued for claims with respect to business interruption losses.

Bruce PowerUnder a long-term agreement reached in 2005 between Bruce Power and the OPA,
Bruce A committed to refurbish and restart the currently idle Units 1 and 2, extend the operating life of Unit 3 and replace the steam generators on Unit 4. An amendment to the
agreement in 2007 provided for a full refurbishment of Unit 4, which will extend the expected operating life of the unit.

In
2008, Bruce Power completed a review of the operating life estimates for Units 3 and 4. As a result of that review, Unit 3 was expected to remain in
commercial service until 2011, providing an additional two years of power generation before refurbishment. After the refurbishment, the operating life of Unit 3 was to be extended to
2038. The review also showed that Unit 4 was expected to remain in commercial service until 2016, providing seven years of generation before refurbishment, after which the estimated
operating life of Unit 4 was expected to be extended to 2042.

Further
amendments to the agreement were made in July 2009. In addition to the amendments made to the Bruce B floor price mechanism, described in the
Energy  Financial Analysis section of this MD&A, other changes to the contract with the OPA included the removal of a support payment cap for Bruce A. The
cumulative support payments received by Bruce A, which are equal to the difference between the fixed prices under the OPA contract and spot market prices, were originally capped at
$575 million until both Units 1 and 2 were restarted. The amendment provides that should either of the restarted Units 1 and 2 not be placed into commercial service by
December 31, 2011, Bruce A will receive no further support payments and all output will receive spot prices until the restart is complete, at which point the Bruce A price will
return to the then prevailing contract levels.

The
July 2009 amendment also provided for deemed generation payments to Bruce Power at the contract prices when Bruce Power generation is reduced due to system
curtailments on the IESO-controlled grid in Ontario.

Additionally,
the capital cost-sharing mechanism for the refurbishment and restart of Bruce A Units 1 and 2 was amended to eliminate the
requirement that the OPA share in any cost overruns exceeding $3.4 billion. Previously the OPA was responsible for 25 per cent of cost overruns above $3.4 billion through a
future adjustment to the fixed price paid to Bruce Power for power generated by the Bruce A units.

The
refurbishment and restart of Bruce A Units 1 and 2 is continuing with a focus on the reassembly of the reactors and related activities. As of
December 31, 2009, Bruce A had incurred approximately $3.2 billion in costs for the refurbishment and restart of these units and approximately $0.2 billion for the
refurbishment of Units 3 and 4. TransCanada believes that the Company's share of the total capital cost to complete the Unit 1 and 2 refurbishment and restart program will be
approximately $2 billion. The bulk of the highly technical, high-risk work on this project is now finished or nearing completion. Although a significant amount of work remains to be
completed, most of it involves conventional power plant construction activity. A project optimization plan implemented by Bruce Power last

year
is achieving success in improving productivity. TransCanada expects that Unit 2 will be restarted in mid-2011, with the Unit 1 restart following approximately
four months later.

Bruce
Power continues to advance an initiative to further extend the operating lives of Units 3 and 4. Unit 4 is now expected to continue to operate beyond
2018 and plans are in place to implement an extensive maintenance program that would result in the life of Unit 3 being extended for a similar period of time.

Portlands EnergyPortlands Energy was completed under budget and fully commissioned in April 2009. The
power plant, which is 50 per cent owned by TransCanada, is able to provide 550 MW of electricity under a 20 year Accelerated Clean Air Supply contract with the OPA.

CoolidgeIn August 2009, TransCanada began construction of the US$500 million Coolidge generating
station located near Phoenix, Arizona. The first of 12 gas-fired turbines began arriving on site in January 2010. The 575 MW, simple-cycle, natural
gas-fired peaking power facility is expected to be in service in second quarter 2011. All of the power produced by the facility will be sold under a 20 year PPA to the Salt River
Project Agricultural Improvement and Power District based in Phoenix, Arizona.

Halton HillsConstruction of Halton Hills continued in 2009 and is nearing completion. The project is a
683 MW natural gas-fired power plant near Halton Hills, Ontario and is expected to be in operation in third quarter 2010 following commissioning, start-up and testing.
TransCanada expects to invest approximately $700 million in the project. Power from the facility will be sold to the OPA under a 20 year Clean Energy Supply contract.

Cartier WindIn third quarter 2009, construction activity began on the 212 MW Gros-Morne and
58 MW Montagne-Sèche wind farms. The Montagne-Sèche project and phase one of the Gros-Morne project (101 MW) are expected to be operational in
2011. Phase two of the Gros-Morne project (111 MW) is expected to be operational in 2012. Gros-Morne and Montagne-Sèche are the fourth and fifth
Québec-based wind farms of the Cartier Wind project. Once they are complete, Cartier Wind, which is 62 per cent owned by TransCanada, will be capable of producing
590 MW of electricity. All of the power produced by Cartier Wind is sold to Hydro-Québec under a 20 year PPA. In fourth quarter 2009, the proposed 150 MW Les
Méchins wind farm, the sixth project in Cartier Wind, was cancelled due to the unavailability of
cost-effective wind turbines and difficulty reaching acceptable agreements with private landowners. This decision has no impact on the other Cartier Wind projects.

Kibby WindIn October 2009, the first phase of the Kibby Wind power project, including 22 turbines
capable of producing a combined 66 MW of power, was placed in service six weeks ahead of schedule and under budget. Construction continues on the 66 MW second phase of the project, which
includes the installation of an additional 22 turbines. This phase is expected to be in service in third quarter 2010. Total cost of construction for both phases of the project is expected to
be approximately US$350 million. The project is expected to be eligible for government incentive payments under the federal U.S. stimulus package.

BécancourIn June 2009, TransCanada entered into an agreement with
Hydro-Québec to continue to suspend all electricity generation from the Bécancour power plant through 2010. Hydro-Québec has the option, subject to certain
conditions, to extend the suspension on an annual basis until such time as regional electricity demand levels recover. TransCanada receives payments under this agreement similar to those that would
have been received under the normal course of operation.

OakvilleIn September 2009, the OPA awarded TransCanada a 20 year Clean Energy Supply contract to
build, own and operate the 900 MW Oakville power generating station in Oakville, Ontario. TransCanada expects to invest approximately $1.2 billion in the natural gas-fired,
combined-cycle plant, which is anticipated to be in service in first quarter 2014.

Power Transmission Line ProjectsTransCanada's open seasons for capacity on its proposed Zephyr and Chinook
power transmission line projects closed in December 2009. A comprehensive review of the bids submitted for each

project
is underway. Each project would be capable of delivering primarily renewable (wind-generated) power originating in Wyoming (Zephyr) and Montana (Chinook) to Nevada.

Broadwater  LNGIn April 2009, the U.S. Department of
Commerce issued a decision upholding New York State's objection to the proposed construction and operation of the Broadwater LNG project, a joint venture between TransCanada and Shell
Broadwater Holdings, LLC. The Broadwater Energy partnership has scaled back near term activities and is assessing its future options with respect to this project.

ENERGY  BUSINESS RISKS

Fluctuating Power and Natural Gas Market PricesTransCanada operates in competitive power and natural gas markets
in North America. Volatility in power and natural gas prices is caused by fluctuating supply and demand, and by general economic conditions. Energy's earnings from the sale of uncontracted volumes are
subject to price volatility. Although Energy commits a significant portion of its supply to medium- to long-term sales contracts, it retains an amount of unsold supply in order to provide
flexibility in managing the Company's portfolio of wholly owned assets.

Capacity PaymentsU.S. Power capacity payments are reset periodically each year and are affected by the
start-up and retirement of power facilities and by fluctuations in demand.

Uncontracted VolumesEnergy has uncontracted power sales volumes in Western Power and U.S. Power. With
the 2008 acquisition of Ravenswood, the level of uncontracted sales volumes in U.S. Power significantly increased. Sales of uncontracted power volumes into the spot market are subject to market
price volatility, which directly impacts earnings. In addition, as power sales contracts expire, any new contracts are entered into at the prevailing market prices. In 2009, prices realized on these
new contracts were generally lower than in recent years due to the significant decrease in power prices in TransCanada's core power markets.

Bruce B
volumes are subject to a floor price mechanism. When the spot market price is above the floor price, Bruce B's non-contracted volumes are
subject to spot price volatility. When spot prices are below the floor price, Bruce B receives the floor price. However, Bruce B's results during this period are still subject to the
impact of fluctuating spot prices upon the settlement of contracted sales. All of the Bruce A output is sold into the Ontario wholesale power spot market under fixed contract price terms with
the OPA and 100 per cent of Eastern Power sales volumes are sold under long-term contracts.

Energy's
natural gas storage business is subject to fluctuating natural gas seasonal spreads generally determined by the differential in natural gas prices in the
traditional summer injection and winter withdrawal seasons. As a result, the Company hedges capacity with a portfolio of contractual capacity sales commitments.

Liquidity RiskA decrease in the number and credit quality of counterparties may increase the Company's exposure
to spot prices by reducing its ability to lock in forward sale prices at acceptable contract terms.

Plant AvailabilityMaintaining plant availability is essential to the continued success of the Energy business.
Plant operating risk is mitigated through a commitment to TransCanada's operational excellence strategy, which is to provide low-cost, reliable operating performance at each of the
Company's facilities. Unexpected plant outages, including unexpected delays in completing planned outages, could result in lower plant output and sales revenue, reduced capacity payments and margins,
and increased maintenance costs. At certain times,
unplanned outages may require power or natural gas purchases at market prices to ensure TransCanada meets its contractual obligations.

WeatherExtreme temperature and weather events in North America and the Gulf of Mexico often create price
volatility and variable demand for power and natural gas. These events may also restrict the availability of power and natural gas. Seasonal changes in temperature can also affect the efficiency and
output capability of natural gas-fired power plants. Variability in wind speeds may impact the earnings of Energy's wind assets.

52MANAGEMENT'S DISCUSSION AND ANALYSIS

---



HydrologyTransCanada's power operations are subject to hydrology risk arising from the ownership of
hydroelectric power generation facilities in the northeastern U.S. Weather changes, weather events, local river management and potential dam failures at these plants or upstream facilities pose
potential risks to the Company.

Execution, Capital Cost and PermittingEnergy's new construction programs in Ontario, Québec,
Maine and Arizona, including its investment in Bruce Power, are subject to execution, capital cost and permitting risks.

Asset CommissioningAlthough each of TransCanada's newly constructed assets goes through rigorous acceptance
testing prior to being placed in service, there is a risk that these assets may have lower than expected availability or performance, especially in their first year of operations.

Regulation of Power MarketsTransCanada operates in both regulated and deregulated power markets. As power
markets evolve across North America, there is the potential for regulatory bodies to implement new rules that could negatively affect TransCanada as a generator and marketer of electricity. These may
be in the form of market rule changes, price caps, emission controls, unfair cost allocations to generators and attempts by others to take out-of-market actions to build excess
generation that negatively affects the price of capacity or energy, or both. In addition, TransCanada's development projects rely on an orderly permitting process and any disruption to that process
can have negative effects on project schedules and costs. TransCanada continues to monitor regulatory issues and regulatory reform and participate in and lead related discussions.

Refer
to the Risk Management and Financial Instruments section of this MD&A for information on additional risks and managing risks in the Energy business.

ENERGY  OUTLOOK

TransCanada assumes that results from its Energy operations in 2010 will be materially consistent with those in 2009 and will include the positive impact of a full year of
earnings from Portlands Energy and phase one of Kibby Wind, as well as incremental earnings from Halton Hills and phase two of Kibby Wind, which are expected to be commissioned in third
quarter 2010.

The
Company expects capacity prices in the New York City market, in which Ravenswood operates, to improve with the long-planned retirement of a power
generating facility owned by the New York Power Authority which occurred at the end of January 2010. The positive impact from this facility's retirement may be partially offset by some
reductions in demand in this market, driven by the economic downturn and the results of energy efficiency investments being made in the region.

The
current economic climate continues to negatively affect demand, liquidity and prices in commodity markets in which TransCanada's Energy segment operates. Earnings in
Western Power, Bruce Power and U.S. Power are expected to be negatively impacted in the near term by the expiry of existing forward sale contracts as new contracts would generally be negotiated
at lower prices.

Although
TransCanada has sold forward significant output from its power plants and Alberta PPAs, as well as capacity from its natural gas storage facilities, Energy's EBITDA
in 2010 can be affected by changes in factors such as the spot market price of power, market heat rates, hydrology, capacity payments, natural gas storage spreads and unplanned outages. EBITDA from
Energy's U.S. operations is also affected by changes in foreign currency exchange rates.

Other
factors such as plant availability, regulatory changes, weather, currency movements and overall stability of the energy industry can also affect 2010 EBITDA. Refer to
the Energy  Business Risks section of this MD&A for a complete discussion of these factors.

Capital ExpendituresEnergy's total capital expenditures in 2009 were $1.5 billion. Energy's overall
capital spending in 2010 is expected to be approximately $1.3 billion, including cash calls for the Bruce A refurbishment and restart project, and continued construction at Coolidge,
Cartier Wind, Kibby Wind, Halton Hills and Oakville.

CORPORATE

Corporate EBIT losses for the year ended December 31, 2009 were $117 million compared to losses of $104 million and $102 million in 2008 and 2007,
respectively. The increases in EBIT losses were primarily due to higher support services costs, reflecting a growing asset base.

Interest expense in 2009 increased $11 million to $954 million from $943 million in each of 2008 and 2007. The
increase in interest on long-term debt reflected new debt issues of US$1.5 billion and $500 million in August 2008, US$2.0 billion in January 2009 and
$700 million in February 2009. In addition, U.S. dollar-
denominated interest expense increased in 2009 due to the impact of a stronger U.S. dollar. These increases were partially offset by higher capitalization of interest to finance the Company's
larger capital spending program primarily due to the construction of Keystone and the acquisition in 2009 of the remaining ownership interest in Keystone from ConocoPhillips. Interest expense in 2009
was positively impacted by reduced losses from changes in the fair value of derivatives used to manage TransCanada's exposure to fluctuating interest rates. Interest expense in 2008 of
$943 million was consistent with 2007. Higher financial charges resulting from financing the Company's 2008 capital program, including the Ravenswood acquisition, and higher losses from changes
in the fair value of derivatives used to manage the Company's exposure to rising interest rates were offset by increased capitalization of interest to finance the Company's larger capital spending
program.

Interest
income and other was $121 million in 2009 compared to $54 million and $120 million in 2008 and 2007, respectively. The increase of
$67 million in 2009 compared to 2008 was primarily due to the positive impact of a weakening U.S. dollar throughout 2009 on U.S. dollar working capital balances and higher gains
from derivatives used to manage the Company's exposure to foreign exchange rate fluctuations. An increase in interest income due to higher cash balances held in 2009 than in 2008 was more than offset
by lower interest rates. The decrease of $66 million in 2008 compared to 2007 was primarily due to lower gains from derivatives used to manage the Company's exposure to foreign exchange rate
fluctuations and the negative impact of a strengthening U.S. dollar throughout 2008.

Income
taxes were $387 million, $602 million and $490 million in 2009, 2008 and 2007, respectively. The decrease of $215 million in 2009 compared
to 2008 was primarily due to reduced pre-tax earnings, higher income tax savings from income tax rate differentials and other positive income tax adjustments in 2009, including
$30 million of favourable adjustments arising from a reduction in the Province of Ontario's corporate income tax rates. The increase in income tax expense of $112 million in 2008
compared to 2007 was primarily due to positive income tax adjustments recorded in 2007 and higher pre-tax earnings in 2008.

Non-controlling
interests were $96 million in 2009 compared to $130 million and $97 million in 2008 and 2007, respectively. The decrease in
2009 compared to 2008 was primarily due to the non-controlling interests' portion of Portland's Calpine bankruptcy settlements in 2008, partially offset by higher PipeLines LP
earnings and the impact of a

stronger
U.S. dollar in 2009. The increase in 2008 compared to 2007 was primarily due to the non-controlling interests' portion of Portland's Calpine bankruptcy settlements
in 2008.

LIQUIDITY AND CAPITAL RESOURCES

TransCanada's financial position remains sound and consistent with recent years as does its ability to generate cash in the short and long term to provide liquidity, maintain
financial capacity and flexibility, and to provide for planned growth. TransCanada's liquidity position remains solid, underpinned by predictable cash flow from operations, significant cash balances
on hand from recent common and preferred share and debt issues, as well as committed revolving bank
lines of US$1.0 billion, $2.0 billion, US$1.0 billion and US$300 million, maturing in November 2010, December 2012, December 2012 and
February 2013, respectively. In addition, TransCanada's proportionate share of capacity remaining available on committed bank facilities at TransCanada-operated affiliates was
$143 million with maturity dates from 2010 through 2012. The Company operates commercial paper programs in Canada and, as at December 31, 2009, had remaining capacity of
$2.45 billion, $2.0 billion and US$4.0 billion under its equity, Canadian debt and U.S. debt shelf prospectuses, respectively. In lieu of making cash dividend payments, a
portion of the declared common and preferred dividends are expected to be paid in common shares issued under the Company's DRP. TransCanada's liquidity, market and other risks are discussed further in
the Risk Management and Financial Instruments section of this MD&A.

CASH FLOW AND CAPITAL RESOURCES

Funds Generated from Operations

|GRAPHIC |  | Funds generated from operations were $3.1 billion in 2009 compared to $3.0 billion and $2.6 billion, in 2008 and 2007, respectively. The increase in 2009 compared to 2008 was primarily due to increased cash
from earnings, partially offset by increased pension contributions in 2009 and the $152 million after tax Calpine bankruptcy settlements in 2008. The Energy business and the Calpine bankruptcy settlements were the primary sources of the increase
in 2008 compared to 2007.

Investing Activities

Capital expenditures totalled $5.4 billion in 2009 compared to $3.1 billion in 2008 and $1.7 billion in 2007. Expenditures in 2009 and 2008 related
primarily to Keystone construction, the refurbishment and restart at Bruce A, construction of
other new pipeline and power facilities, plus the expansion and maintenance of existing pipelines. In addition, in 2009, the Company incurred $3.3 billion of costs related to Keystone,
including approximately $400 million related to the development of the Gulf Coast expansion. Expenditures in 2007 were related primarily to the refurbishment and restart at Bruce A,
construction of new power plants in Canada and maintenance and capacity projects in the Pipelines business.

|GRAPHIC |  | In August 2009, the Company purchased ConocoPhillips' remaining approximate 20 per cent interest in Keystone for US$553 million plus the assumption of US$197 million of short-term debt. Acquisitions in 2009 also included
previous increases in ownership interest in Keystone from ConocoPhillips, discussed below. TransCanada now owns 100 per cent of Keystone.
In 2008, TransCanada entered into an agreement with ConocoPhillips to increase its equity ownership in Keystone to approximately 80 per cent from 50 per cent, with ConocoPhillips' equity ownership in Keystone being reduced
concurrently to approximately 20 per cent from 50 per cent. In 2008 and prior to August 2009, TransCanada funded 100 per cent of the construction expenditures until the participants' cumulative project capital
contributions were aligned with their revised ownership interests. In 2009, prior to August, TransCanada funded $1.3 billion of cash calls for Keystone, resulting in the Company acquiring an incremental increase in ownership of approximately
18 per cent for $313 million. In 2008, the Company funded $362 million of cash calls, resulting in an incremental increase in ownership of approximately 12 per cent for $176 million. TransCanada's ownership interest
was approximately 80 per cent and 62 per cent in August 2009 and at December 31, 2008, respectively.

At
December 31, 2009, total committed revolving and demand credit facilities of $5.2 billion were available to support the Company's commercial paper programs
and for general corporate purposes. These unsecured credit facilities included the following:



The
Company is well positioned to fund its existing capital program through its growing internally-generated cash flow, its DRP and its continued access to capital markets.
As demonstrated by the recent sale of North Baja to PipeLines LP, TransCanada will also continue to examine opportunities for portfolio management, including a greater role for
PipeLines LP, in financing its capital program.

In
July 2009, TransCanada sold North Baja to PipeLines LP. As part of the transaction, TransCanada agreed to amend its incentive distribution rights with
PipeLines LP. TransCanada received aggregate consideration totalling approximately US$395 million from PipeLines LP, including US$200 million in cash and
6,371,680 common units of PipeLines LP. PipeLines LP utilized US$170 million of its US$250 million committed and available bank facility to partially fund this
transaction, which resulted in TransCanada's ownership in PipeLines LP increasing to 42.6 per cent. Subsequent to this transaction, TransCanada's ownership in PipeLines LP
decreased to 38.2 per cent due to PipeLines LP's public issuance of common units as discussed under the heading 2009 Equity Financing Activities in this section.

Short-Term Debt Financing Activities

including the full exercise of a 15 per cent over-allotment option by the underwriters, resulted in gross proceeds of $1.2 billion. The proceeds of the offering were
used by TransCanada to partially fund its capital projects, including Keystone, for general corporate purposes and to repay short-term indebtedness. The common shares were issued under a
prospectus supplement to the base shelf prospectus filed in July 2008.

In
July 2008, TransCanada filed a base shelf prospectus in Canada and the U.S. qualifying for issuance $3.0 billion of common shares, preferred shares
and/or subscription receipts in Canada and the U.S. until August 2010. The shelf replaced a base shelf prospectus filed in January 2007.

prospectus filed in January 2007.

2007 Equity Financing Activities

In first quarter 2007, TransCanada issued 45.4 million common shares at a purchase price of $38.00 per share by prospectus supplement under a base shelf prospectus filed
in Canada and the U.S. in January 2007, resulting in gross proceeds of $1.7 billion. The proceeds were used in financing the acquisition of ANR and Great Lakes.

In
February 2007, PipeLines LP completed a private placement offering of 17.4 million common units at a purchase price of US$34.57 per unit. TransCanada
acquired 50 per cent of the units for US$300 million and invested an additional US$12 million to maintain its general partnership ownership interest in PipeLines LP.
The total private

placement
plus TransCanada's additional investment resulted in gross proceeds to PipeLines LP of US$612 million, which were used to partially finance its Great Lakes acquisition.

Dividend Reinvestment and Share Purchase Plan

Commencing in 2007, TransCanada's Board of Directors authorized the issuance of common shares from treasury at a discount to participants in the Company's DRP. Under this plan,
eligible holders of common or preferred shares of TransCanada and preferred shares of TCPL may reinvest their dividends and make optional cash payments to obtain TransCanada common shares. The DRP
shares are provided to the participants at a discount to the average market price in the five days before dividend payment. The discount was set at two per cent commencing with the dividend
payable in April 2007 and was increased to three per cent commencing with the dividend payable in January 2009. Prior to the April 2007 dividend, TransCanada purchased
shares on the open market and provided them to DRP participants at cost. The Company reserves the right to alter the discount or return to purchasing shares on the open market at any time. In 2009,
dividends of $254 million were paid (2008  $218 million; 2007  $157 million) through the issuance of
8.2 million (2008  6.0 million; 2007  4.1 million) common shares from treasury in accordance with
the DRP.

Dividends

Cash dividends on common shares amounting to $722 million were paid in 2009 (2008  $577 million;
2007  $546 million). In addition, cash dividends of $6 million were paid on preferred shares in 2009. The increase in common share dividends paid
in 2009 from 2008 was primarily due to a greater number of shares outstanding and an increase in the dividend per share amount in 2009, partially offset by the issuance of $254 million of
common shares under the DRP in lieu of cash dividends. The increase in common share dividends paid in 2008 from 2007 was primarily due to a greater number of shares outstanding and an increase in the
dividend per share amount in 2008, partially offset by the Company's issuance in 2008 of $218 million (2007  $157 million) of common shares from
treasury under the DRP in lieu of cash dividends.

In
February 2010, TransCanada's Board of Directors approved an increase in the quarterly common share dividend payment to $0.40 per share from $0.38 per share for the
quarter ending March 31, 2010. This was the tenth consecutive year in which the dividend was increased, resulting in a per share dividend that has doubled since 2000. In addition, a quarterly
dividend of $0.2875 per preferred share was declared for the quarter ending March 31, 2010.

Issuer Ratings

TransCanada's issuer rating assigned by Moody's Investors Service (Moody's) is Baa1 with a stable outlook. On September 30, 2009, DBRS and Standard and Poor's
(S&P) assigned ratings of Pfd-2 (low) and P-2, respectively, to TransCanada's cumulative redeemable first preferred shares, Series 1 and, in connection with the offering
of the preferred shares, S&P assigned TransCanada an A- long-term corporate credit rating with a stable outlook. TCPL's senior unsecured debt is rated A with a
stable outlook by DBRS, A3 with a stable outlook by Moody's, and A- with a stable outlook by S&P.

CONTRACTUAL OBLIGATIONS

Obligations and Commitments

At December 31, 2009, the Company had $16.7 billion of total long-term debt and $1.0 billion of junior subordinated notes, compared to
$16.2 billion of total long-term debt and $1.2 billion of junior subordinated notes at December 31, 2008. TransCanada's share of the total debt of joint ventures,
including capital lease obligations, was $1.0 billion at December 31, 2009, compared to $1.1 billion at December 31, 2008. Total notes payable, including TransCanada's
proportionate share of the notes payable of joint ventures, were $1.7 billion at December 31, 2009 and December 31, 2008. TransCanada has provided certain pro-rata
guarantees related to the capital lease and performance obligations of Bruce Power and certain other partially owned entities.

TransCanada's commitments under the Alberta PPAs are considered to be operating leases and a portion of these PPAs have been
subleased to third parties under similar terms and conditions. Future payments under these PPAs have been excluded from operating leases in the above table, as these payments are dependent upon plant
availability among other factors. TransCanada's share of power purchased under the PPAs in 2009 was $384 million (2008  $398 million;
2007  $391 million).

At
December 31, 2009, scheduled principal repayments and interest payments related to long-term debt and the Company's proportionate share of the
long-term debt of joint ventures were as follows:

TransCanada and its affiliates have long-term natural gas transportation and natural gas purchase arrangements as well as
other purchase obligations, all of which are transacted at market prices and in the normal course of business. Potential future commitments are discussed in the
Pipelines  Opportunities and Developments and Energy  Opportunities and Developments sections in this MD&A.

In
2010, TransCanada expects to make funding contributions of approximately $115 million for the defined benefit pension plans and approximately $28 million
for the Company's other post-retirement benefit plans, savings plan and defined contribution pension plans. This represents a decrease from total funding contributions of
$168 million in 2009 and is attributable primarily to significantly improved investment performance and to plan experience being different than expectations. TransCanada's proportionate share
of funding contributions expected to be made by joint ventures to their respective pension and other post-retirement benefit plans in 2010 is approximately $57 million and $6 million,
respectively, compared to total contributions of $54 million in 2009.

MANAGEMENT'S DISCUSSION AND ANALYSIS63

---



The
next actuarial valuation for the Company's pension and other post-retirement benefit plans will be carried out as at January 1, 2011. TransCanada
expects funding requirements for these plans to continue at the anticipated 2010 level for the next several years to amortize solvency deficiencies in addition to normal costs. The Company's 2010 net
benefit cost is expected to increase modestly from 2009. However, future net benefit costs and the amount of funding contributions will be dependent on various factors, including investment returns
achieved on plan assets, the level of interest rates, changes to plan design and actuarial assumptions, actual plan experience versus projections and amendments to pension plan regulations and
legislation. Increases in the level of required plan funding are not expected to have a material impact on the Company's liquidity.

Bruce Power

Bruce A has signed commitments to third-party suppliers related to refurbishing and restarting Units 1 and 2. TransCanada's share of these signed commitments, which
extend over a two year period ending December 31, 2011, totals $295 million.

Aboriginal Pipeline Group

Under its agreement with the APG, TransCanada agreed to finance the APG's one-third share of the MGP project's predevelopment costs. These costs are currently
forecast to be between $150 million and $200 million, on a cumulative basis, depending on the pace of project development. As at December 31, 2009, the Company had advanced
$143 million of this total. This agreement is discussed further in the Pipelines  Opportunities and Developments section of this MD&A.

Contingencies

TransCanada is subject to laws and regulations governing environmental quality and pollution control. At December 31, 2009, the Company had recorded liabilities of
approximately $67 million representing its estimate of the amount it expects to expend to remediate certain sites. However, additional liabilities may be incurred as more assessments occur and
remediation efforts continue.

TransCanada
and its subsidiaries are subject to various legal proceedings and actions arising in the normal course of business. While the final outcome of such legal
proceedings and actions cannot be predicted with certainty, it is the opinion of management that the resolution of such proceedings and actions will not have a material impact on the Company's
consolidated financial position or results of operations.

Guarantees

TransCanada, Cameco Corporation and BPC have severally guaranteed one-third of certain contingent financial obligations of Bruce B related to power sales
agreements, a lease agreement and contractor services. The guarantees have terms ranging from 2018 to perpetuity. In addition, TransCanada and BPC have severally guaranteed one-half of
certain contingent financial obligations related to an agreement with the OPA to refurbish and restart Bruce A power generation units. The guarantees were provided as part of the reorganization
of Bruce Power in 2005 and have terms ending in 2018 and 2019. In its 2009 decision to renew the operating licenses of Bruce Power, the Canadian Nuclear Safety Commission ordered that it was no longer
necessary for the major partners of Bruce Power, including TransCanada, to provide financial assurances to Bruce Power to support its license obligations. TransCanada's share of the potential exposure
under the remaining Bruce A and Bruce B guarantees was estimated at
December 31, 2009 to be approximately $741 million. The fair value of these Bruce Power guarantees is estimated to be $82 million. The Company's exposure under certain of these
guarantees is unlimited.

In
addition to the guarantees for Bruce Power, the Company and its partners in certain other jointly owned entities have either (i) jointly and severally,
(ii) jointly or (iii) severally guaranteed the financial performance of these entities related primarily to redelivery of natural gas, PPA payments and the payment of liabilities.
TransCanada's share of the potential exposure under these guarantees was estimated at December 31, 2009 to range from $351 million to a maximum of $632 million. The fair value of
these guarantees is estimated to be $9 million which has been included in deferred amounts. The Company's exposure under certain of these guarantees is unlimited. For certain of these entities,
any payments made by TransCanada under these guarantees in excess of its ownership interest are to be reimbursed by its partners.

RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

FINANCIAL RISKS AND FINANCIAL INSTRUMENTS

Risk Management Overview

TransCanada has exposure to market risk, counterparty credit risk and liquidity risk. TransCanada engages in risk management activities with the objective being to protect
earnings, cash flow and, ultimately, shareholder value.

Risk
management strategies, policies and limits are designed to ensure TransCanada's risks and related exposures are in line with the Company's business objectives and risk
tolerance. Risks are managed within limits ultimately established by the Company's Board of Directors, implemented by senior management and monitored by risk management and internal audit personnel.
The Board of Directors' Audit Committee oversees how management monitors compliance with risk management policies and procedures, and oversees management's review of the adequacy of the risk
management framework. Internal audit personnel assist the Audit Committee in its oversight role by performing regular and ad-hoc reviews of risk management controls and procedures, the
results of which are reported to the Audit Committee.

Market Risk

The Company constructs and invests in large infrastructure projects, purchases and sells energy commodities, issues short-term and long-term debt,
including amounts in foreign currencies, and invests in foreign operations. These activities expose the Company to market risk from changes in commodity prices, foreign exchange rates and interest
rates, which affect the Company's earnings and the value of the financial instruments it holds.

The
Company uses derivatives as part of its overall risk management strategy to manage the exposure to market risk that results from these activities. Derivative contracts
used to manage market risk generally consist of the following:

Commodity Price Risk

The Company is exposed to commodity price movements as part of its normal business operations, particularly in relation to the prices of electricity, natural gas and oil
products. A number of strategies are used to mitigate these exposures, including the following:

MANAGEMENT'S DISCUSSION AND ANALYSIS65

---



The
Company assesses its commodity contracts and derivative instruments used to manage commodity risk to determine the appropriate accounting treatment. Contracts, with the
exception of leases, have been assessed to determine whether they or certain aspects of them meet the definition of a derivative. Certain commodity purchase and sale contracts are derivatives but are
not within the scope of Canadian Institute of Chartered Accountants (CICA) Handbook Section 3855 "Financial Instruments  Recognition and Measurement", as
they were entered into and continue to be held for the purpose of receipt or delivery in accordance with the Company's expected purchase, sale or usage requirements. Certain other contracts are not
within the scope of Section 3855 as they are considered to meet other exemptions.

TransCanada
manages its exposure to seasonal natural gas price spreads in its natural gas storage business by economically hedging storage capacity with a portfolio of
third-party storage capacity contracts and proprietary natural gas purchases and sales. TransCanada simultaneously enters into a forward purchase of natural gas for injection into storage and an
offsetting forward sale of natural gas for withdrawal at a later period, thereby locking in future positive margins and effectively eliminating exposure to natural gas price movements. Fair value
adjustments recorded each period on proprietary natural gas inventory in storage and these forward contracts may not be representative of the amounts that will be realized on settlement.

Natural Gas Inventory Price Risk

At December 31, 2009, the fair value of proprietary natural gas inventory in storage, as measured using a weighted average of forward prices for the following four
months less selling costs, was $73 million (2008  $76 million). The change in fair value of proprietary natural gas inventory in storage in 2009
resulted in a net pre-tax unrealized gain of $3 million (2008  unrealized loss of $7 million;
2007  nil), which was recorded as an increase to Revenues and Inventories. The net change in fair value of natural gas forward purchase and sales contracts in
2009 resulted in a net pre-tax unrealized loss of $2 million (2008  unrealized gain of $7 million;
2007  unrealized gain of $10 million), which was recorded as a decrease in revenues.

Foreign Exchange and Interest Rate Risk

Foreign exchange and interest rate risk is created by fluctuations in the fair value or cash flow of financial instruments due to changes in foreign exchange rates and market
interest rates.

A
portion of TransCanada's earnings from its Pipelines and Energy segments is generated in U.S. dollars and, as such, movement of the Canadian dollar relative to the
U.S. dollar can affect TransCanada's earnings. This foreign exchange impact is offset by certain related debt and financing costs being denominated in U.S. dollars and by the Company's
hedging activities. TransCanada currently has a greater exposure to U.S. currency fluctuations than in prior years due to significant growth in its U.S. operations, partially
offset by increased levels of U.S. dollar-denominated debt.

The
Company uses foreign currency and interest rate derivatives to manage the foreign exchange and interest rate risks related to its debt and other
U.S. dollar-denominated transactions, and to manage the interest rate exposures of the Canadian Mainline, Alberta System and Foothills operations. Certain of the realized gains and losses on
these derivatives are shared with shippers on predetermined terms. These gains and losses are deferred as regulatory assets and liabilities until they are recovered from or paid to the shippers in
accordance with the terms of the shipping agreements.

TransCanada
has floating interest rate debt, which subjects it to interest rate cash flow risk. The Company uses a combination of interest rate swaps and options to manage
its exposure to this risk.

On
a consolidated basis, the impact of changes in the U.S. dollar on U.S. Pipelines and Energy earnings is largely offset by the impact on U.S. dollar
interest expense. The resultant net exposure is managed using derivatives, effectively reducing the Company's exposure to changes in foreign exchange rates.

Net Investment in Self-Sustaining Foreign Operations

The Company hedges its net investment in self-sustaining foreign operations (on an after-tax basis) with U.S. dollar-denominated debt,
cross-currency interest rate swaps, forward foreign exchange contracts and foreign exchange options. At December 31, 2009, the Company had designated as a net investment hedge
U.S. dollar-denominated debt with a carrying value of $7.9 billion (US$7.6 billion) (2008  $7.2 billion (US$5.9 billion)) and
a fair value of $9.8 billion (US$9.3 billion) (2008  $5.9 billion (US$4.8 billion)). At December 31, 2009, $96 million
was included in Intangibles and Other Assets (2008  $254 million in Deferred Amounts) for the fair value of the forwards, swaps and options used to hedge
the Company's net U.S. dollar investment in foreign operations.

The
fair values and notional or principal amounts for the derivatives designated as a net investment hedge were as follows:

VaR Analysis

TransCanada uses a Value-at-Risk (VaR) methodology to estimate the potential impact resulting from its exposure to market risk on its open liquid
positions. VaR estimates the potential change in pre-tax earnings over a given holding period for a specified confidence level. The VaR number calculated and used by TransCanada reflects a
95 per cent probability that the daily change resulting from normal market fluctuations in its open liquid positions will not exceed the reported VaR. The VaR methodology is a
statistically-calculated, probability-based approach that takes into consideration market volatilities as well as risk diversification by recognizing offsetting positions and correlations among
products and markets. Risks are measured across all products and markets, and risk measures are aggregated to arrive at a single VaR number.

There
is currently no uniform industry methodology for estimating VaR. The use of VaR has limitations because it is based on historical correlations and volatilities in
commodity prices, interest rates and foreign exchange rates, and assumes that future price movements will follow a statistical distribution. Although losses are not expected to exceed the
statistically estimated VaR on 95 per cent of occasions, losses on the other five per cent of occasions could be substantially greater than the estimated VaR.

TransCanada's
estimation of VaR includes wholly owned subsidiaries and incorporates relevant risks associated with each market or business unit. The calculation does not
include the Pipelines segment as the rate-regulated nature of the pipeline business reduces the impact of market risks. TransCanada's Board of Directors has established a VaR limit, which
is monitored on an ongoing basis as part of the Company's risk management policy. TransCanada's consolidated

VaR
was $12 million at December 31, 2009 (2008  $23 million). The decline from December 31, 2008 was primarily due to decreased
prices and lower open positions in the U.S. power portfolio.

Counterparty Credit Risk

Counterparty credit risk represents the financial loss the Company would experience if a counterparty to a financial instrument failed to meet its obligations in accordance
with the terms and conditions of its contracts with the Company.

Counterparty
credit risk is managed through established credit management techniques, including conducting financial and other assessments to establish and monitor a
counterparty's creditworthiness, setting exposure limits, monitoring exposures against these limits, using master netting arrangements and obtaining financial assurances where warranted. In general,
financial assurances include guarantees, letters of credit and cash. The Company monitors and manages its concentration of counterparty credit risk on an ongoing basis. The Company believes these
measures minimize its counterparty credit risk but there is no certainty that they will protect it against all material losses.

TransCanada's
maximum counterparty credit exposure with respect to financial instruments at the balance sheet date consisted primarily of non-derivative
financial assets such as accounts receivable, loans and notes receivable, as well as the fair value of derivative assets. Within these balances, the Company does not have significant concentrations of
counterparty credit risk with any individual counterparties and the majority of counterparty credit exposure is with counterparties who are investment grade. At December 31, 2009, there were no
significant amounts past due or impaired.

TransCanada
has significant credit and performance exposures to financial institutions as they provide committed credit lines and cash deposit facilities, critical liquidity
in the foreign exchange derivative, interest rate derivative and energy wholesale markets, and letters of credit to mitigate TransCanada's exposure to non-creditworthy counterparties.

As
a level of uncertainty continues to exist in the global financial markets, TransCanada continues to closely monitor and reassess the creditworthiness of its
counterparties. This has resulted in TransCanada reducing or mitigating its exposure to certain counterparties where it was deemed warranted and permitted under contractual terms. As part of its
ongoing operations, TransCanada must balance its market and counterparty credit risks when making business decisions.

Certain
subsidiaries of Calpine filed for bankruptcy protection in both Canada and the U.S. in 2005. Gas Transmission Northwest Corporation (GTNC) and Portland
reached agreements with Calpine for allowed unsecured claims in the Calpine bankruptcy. In February 2008, GTNC and Portland received initial distributions of 9.4 million common shares
and 6.1 million common shares, respectively, of Calpine, which represented approximately 85 per cent of their agreed-upon claims. In 2008, these shares were sold into
the open market and resulted in total pre-tax gains of $279 million. Claims by NGTL and Foothills Pipe Lines (South B.C.) Ltd. for $32 million and $44 million,
respectively, were received in cash in January 2008 and were passed on to shippers on these systems in 2008 and 2009.

Liquidity Risk

Liquidity risk is the risk that TransCanada will not be able to meet its financial obligations when due. The Company's approach to managing liquidity risk is to ensure that,
under both normal and stressed conditions, it always has sufficient cash and credit facilities to meet its obligations when due without incurring unacceptable losses or damage to the Company's
reputation.

Management
continuously forecasts cash flows for a period of 12 months to identify financing requirements. These requirements are then managed through a combination
of committed and demand credit facilities and access to capital markets, as discussed under the heading Capital Management below.

At
December 31, 2009, the Company had committed revolving bank lines of US$1.0 billion, $2.0 billion, US$1.0 billion and US$300 million
maturing November 2010, December 2012, December 2012 and February 2013, respectively. At December 31, 2009, the US$300 million facility was fully drawn and no
draws were made on any of the other facilities. The Company has maintained continuous access to the Canadian commercial paper market on competitive terms.

The
Company has access to capital markets under the following prospectuses:

Capital Management

The primary objective of capital management is to ensure TransCanada has strong credit ratings to support its businesses and maximize shareholder value. In 2009, the overall
objective and policy for managing capital remained unchanged from the prior year.

TransCanada
manages its capital structure in a manner consistent with the risk characteristics of the underlying assets. The Company's management considers its capital
structure to consist of net debt, non-controlling interests and shareholders' equity. Net debt is comprised of notes payable, long-term debt and junior subordinated notes less
cash and cash equivalents. Net debt only includes obligations that the Company controls and manages. Consequently, it does not include cash and cash equivalents, notes payable and
long-term debt of TransCanada's joint ventures. The Company's capital structure was as follows:

Fair Values

Certain financial instruments included in cash and cash equivalents, accounts receivable, intangibles and other assets, notes payable, accounts payable, accrued interest and
deferred amounts have carrying amounts that approximate their fair value due to the nature of the item or the short time to maturity. The fair value of foreign exchange and interest rate derivatives
has been calculated using year-end market rates. The fair value of power, natural gas and oil products derivatives has been calculated using quoted market prices where available. In the
absence of quoted market prices,

broker quotes or other valuation techniques are used. Credit risk has been taken into consideration when calculating the fair value of derivatives.

The
fair value of the Company's long-term debt was estimated based on quoted market prices for the same or similar debt instruments and, when such information
was not available, was estimated by discounting future payments of interest and principal at estimated interest rates that were made available to the Company.

A 10 per cent increase or 10 per cent decrease in commodity prices, with all other variables held
constant, would cause an $18 million decrease or an $18 million increase, respectively, in the fair value of derivative financial instruments outstanding as at
December 31, 2009.

A
100 basis points increase or 100 basis points decrease in the letter of credit rate, with all other variables held constant, would cause a $6 million
increase or a $6 million decrease, respectively, in the fair value of guarantee liabilities outstanding as at December 31, 2009. Similarly, the effect of a 100 basis points
increase or 100 basis points decrease in the discount rate on the fair value of guarantee liabilities outstanding as at December 31, 2009 would cause a $2 million decrease in the
liability or a $2 million increase in the liability, respectively.

OTHER RISKS

Development Projects and Acquisitions

TransCanada continues to focus on growing its Pipelines and Energy operations through greenfield development projects and acquisitions. TransCanada capitalizes costs incurred
on certain of its projects during the development period
prior to construction when the project meets specific criteria and is expected to proceed through to completion. The related capital costs of a project that does not proceed through to completion are
expensed at the time it is discontinued. There is a risk with respect to TransCanada's acquisition of assets and operations that certain commercial opportunities and operational synergies may not
materialize as expected and would subsequently be subject to an impairment writedown.

Health, Safety and Environment Risk Management

Health, safety and environment (HS&E) are top priorities in all of TransCanada's operations and activities in these areas are guided by the Company's HS&E Commitment Statement.
The Commitment Statement outlines guiding principles for a safe and healthy environment for TransCanada's employees, contractors and the public, and for TransCanada's commitment to protect the
environment. All employees are held responsible and accountable for HS&E performance. The Company is committed to being an industry leader in conducting its business so that it meets or exceeds all
applicable laws and regulations, and minimizes risk to people and the environment. The Company is committed to tracking and improving its HS&E performance, and to promoting safety on and off the job
in the belief that all occupational injuries and illnesses are preventable. TransCanada endeavours to do business with companies and contractors that share its perspective on HS&E performance and to
influence them to improve their collective performance. TransCanada is committed to respecting the diverse environments and cultures in which it operates and to supporting open communication with the
public, policy makers, scientists and public interest groups.

TransCanada
is committed to ensuring compliance with its internal policies and legislated requirements. The HS&E Committee of TransCanada's Board of Directors monitors
compliance with the Company's HS&E corporate policy through regular reporting. TransCanada's HS&E management system is modeled on the International Organization for

74MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Standardization's
(ISO) standard for environmental management systems, ISO 14001, and focuses resources on the areas of significant risk to the organization's HS&E business activities.
Management is informed regularly of all important HS&E operational issues and initiatives through formal reporting processes. TransCanada's HS&E management system and performance are assessed by an
independent outside firm every three years. The most recent assessment occurred in December 2009 and did not identify any material issues. The HS&E management system is subject to ongoing
internal review to ensure that it remains effective as circumstances change.

In
2009, employee and contractor health and safety performance continued to be a top priority. TransCanada's objective is a health and safety performance consistent with top
quartile companies in its sectors. Overall, the Company's safety frequency rates in 2009 continued to be better than most industry benchmarks.

The
safety and integrity of the Company's existing and newly developed infrastructure also continued to be top priorities. All new assets are designed, constructed and
commissioned with full consideration given to safety and integrity, and are not brought into service until all necessary requirements are satisfied. The Company expects to spend approximately
$181 million in 2010 for pipeline integrity on its wholly owned pipelines, which is $10 million higher than in 2009 primarily due to increased levels of in-line pipeline
inspection on all
systems. Under the approved regulatory models in Canada, pipeline integrity expenditures on NEB regulated pipelines are treated on a flow-through basis and, as a result, have no impact on
TransCanada's earnings. Under the Keystone contracts, pipeline integrity expenditures are recovered through the tolling mechanism and, as a result, have no impact on TransCanada's earnings.
Expenditures for GTN may also be recovered through a cost recovery mechanism in its rates. TransCanada's pipeline safety record in 2009 continued to be above industry benchmarks. TransCanada
experienced three pipeline breaks in 2009. The first occurred in a remote part of northern Alberta. The other two occurred in rural parts of northern Ontario. The breaks resulted in minimal impact
with no injuries and only minor property damage in one of the incidents. All three incidents were subject to a Level 3 investigation by the Transportation Safety Board of Canada. Spending
associated with public safety on the Energy assets is focused primarily on the Company's hydro dams and associated equipment, and is consistent with previous years.

Environment

TransCanada's facilities are subject to various federal, provincial, state and local statutes and regulations, including requirements to establish compliance and remediation
obligations. Compliance obligations can result in significant costs associated with installing and maintaining pollution controls, fines and penalties resulting from any failure to comply, and
potential limitations on operations. Remediation obligations can result in significant costs associated with the investigation and remediation of contaminated properties, some of which have been
designated as Superfund sites by the U.S. Environmental Protection Agency under theComprehensive Environmental Response, Compensation and Liability
Act, and with damage claims arising out of the contamination of properties. It is not possible for the Company to estimate the amount and timing of all future expenditures
related to environmental matters due to:

Environmental
risks from TransCanada's operating facilities typically include: air emissions, such as nitrogen oxides, particulate matter and greenhouse gases; potential
impacts on land, including land reclamation or restoration following construction; the use, storage or release of chemicals or hydrocarbons; the generation, handling and disposal of wastes and
hazardous wastes; and water impacts such as uncontrolled water discharge. Environmental controls including physical design, programs, procedures and processes are in place to effectively manage these
risks. TransCanada has

MANAGEMENT'S DISCUSSION AND ANALYSIS75

ongoing
inspection programs designed to keep all of its facilities in compliance with environmental requirements and the Company is confident that its systems are in material compliance with the
applicable requirements.

In
2009, TransCanada conducted environmental risk assessments and remediation work, as well as various retirement, reclamation and restoration activities on its Canadian and
U.S. facilities. At December 31, 2009, TransCanada had recorded liabilities of approximately $91 million (2008  $86 million) for
remediation obligations and compliance costs associated with greenhouse gas (GHG) legislation. The Company believes it has considered all necessary contingencies and established appropriate reserves
for environmental liabilities. However, there is the risk that unforeseen matters may arise requiring the Company to set aside additional amounts.

TransCanada
is not aware of any material outstanding orders, claims or lawsuits against the Company in relation to the release or discharge of any material into the
environment or in connection with environmental protection.

North
American climate change policy continues to evolve at regional and national levels. While recent political and economic events may significantly affect the scope and
timing of new measures that are put in place, TransCanada anticipates that most of the Company's facilities in Canada and the U.S. are or will be captured under federal or regional climate
change regulations to manage industrial GHG emissions.

In
2009, the Company owned assets in three Canadian provinces where regulations exist to address industrial GHG emissions. TransCanada has put in place procedures to address
these regulations.

In
Alberta, under the Specified Gas Emitters Regulation, industrial facilities are required to reduce GHG emissions intensities by 12 per cent, effective
July 2007. TransCanada's Alberta-based facilities are subject to this regulation, as are the Sundance and Sheerness coal-fired power facilities with which TransCanada has PPAs. As
an alternative to reducing emissions intensities, compliance can be achieved through the retirement of offsets or payments to a technology fund at a cost of $15 per tonne of carbon dioxide
(CO2) in excess of the mandated reduction. A program is in place to manage the compliance costs incurred by these assets as a result of the regulation. Compliance costs on the Alberta
System are recovered through tolls paid by customers. Recovery of compliance costs at the Company's power generation facilities in Alberta is dependent ultimately on market prices for electricity.
TransCanada has estimated and recorded costs of $17 million for 2009. These costs will be finalized when compliance reports are submitted in March 2010.

The
hydrocarbon royalty in Québec is collected by the natural gas distributor on behalf of the Québec government through a green fund
contribution charge on gas consumed. In 2009, the cost pertaining to the Bécancour facility arising from the hydrocarbon royalty was less than $1 million as a result of an
agreement between TransCanada and Hydro-Québec to temporarily suspend the facility's power generation. The cost is expected to increase when the plant returns to service.

B.C.'s
carbon tax, which came into effect in mid-2008, applies to CO2 emissions arising from fossil fuel combustion. Compliance costs for fuel
combustion at the Company's compressor and meter stations in B.C. are recovered through tolls paid by customers. Costs related to the carbon tax in 2009 were $3 million. The cost per tonne of
CO2 was $15 in 2009 and will increase to $20 per tonne and $25 per tonne in 2010 and 2011, respectively.

TransCanada
has assets located in provinces where members of the Western Climate Initiative (WCI) have drafted regulations that apply to industrial GHG emitters. The
Canadian WCI members include B.C., Manitoba, Ontario and Québec. The draft climate change strategies are expected to come into effect in 2012 and are expected to affect TransCanada's
pipeline and power facilities. The details of how these provincial programs will align with the Canadian government's climate change policies remain uncertain.

Seven
western U.S. states, along with the four Canadian provinces discussed above, are focused on the implementation of a cap and trade program under the WCI. Members
of the WCI have set a GHG emission reduction target of 15 per cent below 2005 levels by 2020. California, a WCI founding member, has released draft cap and trade regulations that, if
enacted, are anticipated to have an impact on the Company's pipeline assets in the state. The

financial
implications to TransCanada are not expected to be material. Under the current form of draft regulations in Washington and Oregon it is expected that there will not be a significant cost of
compliance in these states. TransCanada will continue to monitor these developments.

The
Canadian government has continued to express interest in pursuing a harmonized continental climate change strategy. In January 2010, Environment Canada presented
a revised target to the United Nations Framework Convention on Climate Change as part of its submission for theCopenhagen Accord. The submitted target
represents a 17 per cent reduction in GHG emissions by 2020 relative to 2005 levels. The submission states that Canada will align with the final economy-wide emissions
targets of the U.S. in enacted legislation. The Company expects that pipeline and power generation emissions will be subject to reduction targets for industrial emitters.

Emission
allowances or credits purchased for compliance are recorded on the balance sheet at historical cost and expensed when they are retired. Compliance payments are
expensed when incurred. Allowances granted to or internally generated by TransCanada are not attributed a value for accounting purposes. When required,
TransCanada accrues emission liabilities on the balance sheet upon the generation or sale of power using the best estimate of the amount required to settle the obligation. Allowances or credits not
used for compliance are sold and recorded as revenue. In 2009, costs of compliance and revenues from the sale of allowances were not significant.

Northeastern
U.S. states that are members of the Regional Greenhouse Gas Initiative (RGGI) implemented a CO2 cap and trade program for electricity
generators effective January 1, 2009. Under the RGGI, both the Ravenswood and OSP power generation facilities will be required to submit allowances by December 31, 2011. TransCanada
participated in the quarterly auctions of allowances for Ravenswood and OSP, and incurred related costs of $8 million in 2009. These costs were generally recovered through the power market and
the net impact on TransCanada was not significant.

Participants
in theMidwestern Greenhouse Gas Reduction Accord, which involves six U.S. states and the province of
Manitoba, are developing a regional strategy for reducing members' GHG emissions that will include a multi-sector cap and trade mechanism. Draft recommendations have been released but as yet not
formally endorsed by participant states and Manitoba.

Climate
change is a strategic issue for the U.S. government and federal policy to manage domestic GHG emissions continues to be a priority. The Environmental
Protection Agency has released an endangerment finding regarding GHG emissions under theClean Air Act. This finding was to determine whether the six
types of GHGs in the atmosphere threaten the health and welfare of current and future generations. The U.S. House of Representatives passed a climate bill in June 2009 and the
U.S. Senate is deliberating on a series of climate bills.

TransCanada
monitors climate change policy developments and, when warranted, participates in policy discussions. The Company is also continuing its programs to manage GHG
emissions from its facilities and to evaluate new processes and technologies that result in improved efficiencies and lower GHG emission rates.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in reports filed with, or submitted to, securities
regulatory authorities is recorded, processed, summarized and reported within the time periods specified under Canadian and U.S. securities laws. The information is accumulated and communicated
to management, including the President and Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosure.

As
at December 31, 2009, an evaluation of the effectiveness of TransCanada's disclosure controls and procedures as defined under the rules adopted by the Canadian
securities regulatory authorities and by the SEC was carried out under the supervision and with the participation of management, including the President and Chief Executive Officer and the Chief
Financial Officer. Based on this evaluation, the President and Chief Executive Officer and the Chief Financial

Officer
concluded that the design and operation of TransCanada's disclosure controls and procedures were effective as at December 31, 2009.

Management's Annual Report on Internal Control over Financial Reporting

Internal control over financial reporting is a process designed by or under the supervision of senior management and effected by the Board of Directors, management and other
personnel to provide reasonable assurance regarding the reliability of financial reporting and preparation of consolidated financial statements for external purposes in accordance with Canadian GAAP,
including a reconciliation to U.S. GAAP.

Management
is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting, no matter how well
designed, has inherent limitations and can only provide reasonable assurance with respect to the preparation and fair presentation of published financial statements. Under the supervision and with the
participation of the President and Chief Executive Officer and the Chief Financial Officer, management conducted an evaluation of the effectiveness of its internal control over financial reporting
based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based
on this evaluation, management concluded that internal control over financial reporting is effective as at December 31, 2009, to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes.

In
2009, there was no change in TransCanada's internal control over financial reporting that materially affected or is reasonably likely to materially affect TransCanada's
internal control over financial reporting.

CEO and CFO Certifications

TransCanada's President and Chief Executive Officer and Chief Financial Officer have filed with the SEC and the Canadian securities regulators certifications regarding the
quality of TransCanada's public disclosures relating to its fiscal 2009 reports filed with the SEC and the Canadian securities regulators.

SIGNIFICANT ACCOUNTING POLICIES AND CRITICAL ACCOUNTING ESTIMATES

To prepare financial statements that conform with Canadian GAAP, TransCanada is required to make estimates and assumptions that affect both the amount and timing of recording
assets, liabilities, revenues and expenses, since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful
judgment in making these estimates and assumptions. The Company believes the following accounting policies and estimates require it to make assumptions about highly uncertain matters and changes in
these estimates could have a material impact on the Company's financial information.

Regulated Accounting

The Company accounts for the impacts of rate regulation in accordance with GAAP. Three criteria must be met to use these accounting principles:

The
Company's management believes all three of these criteria have been met with respect to each of the regulated natural gas pipelines accounted for using regulated
accounting principles. The most significant
impact from the use of these accounting principles is that the timing of recognition of certain expenses and revenues in the regulated businesses may differ from that otherwise expected under GAAP in
order to appropriately reflect the economic impact of the regulators' decisions regarding the Company's revenues and tolls.

78MANAGEMENT'S DISCUSSION AND ANALYSIS

---



Effective
January 1, 2009, the Company's accounting for its future income taxes recorded on rate-regulated operations changed as discussed in the
Accounting Changes section of this MD&A.

Financial Instruments and Hedges

Financial Instruments

The Company initially records all financial instruments on the balance sheet at their fair value. Subsequent measurement of the financial instruments is based on their
classification. Financial assets are classified into the following categories: held for trading, available for sale, held-to-maturity investments and loans and receivables.
Financial liabilities are classified as held for trading or other financial liabilities. The Company does not have any held-to-maturity investments.

Held-for-trading
derivative financial assets and liabilities consist of swaps, options, forwards and futures. Commodity
held-for-trading financial instruments are initially recorded at their fair value and changes to fair value are included in revenues. Changes in the fair value of interest rate
and foreign exchange rate held-for-trading instruments are recorded in interest expense and in interest income and other, respectively.

The
available-for-sale classification includes non-derivative financial assets that are designated as available for sale or are not
included in the other three classifications. These instruments are accounted for initially at their fair value and changes to fair value are recorded through other comprehensive income. Trade
receivables, loans and other receivables with fixed or determinable payments that are not quoted in an active market are classified as "loans and receivables" and are measured at amortized cost using
the effective interest method, net of any impairment. Other financial liabilities consist of liabilities not classified as held for trading. Items in this financial instrument category are recognized
at amortized cost using the effective interest method.

The
recognition of gains and losses on the derivatives for the Canadian Mainline, Alberta System and Foothills exposures is determined through the regulatory process. The
gains and losses on derivatives accounted for as part of rate-regulated accounting are deferred in Regulatory Assets or Regulatory Liabilities.

Hedges

The Company applies hedge accounting to its arrangements that qualify for hedge accounting treatment, which include fair value and cash flow hedges, and hedges of foreign
currency exposures of net investments in self-sustaining foreign operations. Hedge accounting is discontinued prospectively when the hedging relationship ceases to be effective or the
hedging or hedged items cease to exist as a result of maturity, expiry, sale, termination, cancellation or exercise.

In
a fair value hedging relationship, the carrying value of the hedged item is adjusted for changes in fair value attributable to the hedged risk. The changes in fair value
are recognized in net income. Changes in the fair value of the hedged item, to the extent that the hedging relationship is effective, are offset by changes in the fair value of the hedging item, which
are also recorded in net income.

In
a cash flow hedging relationship, the effective portion of the change in the fair value of the hedging derivative is recognized in other comprehensive income, while any
ineffective portion is recognized in net income in the same financial category as the underlying transaction. When hedge accounting is discontinued, the amounts recognized previously in accumulated
other comprehensive income are reclassified to net income during the periods when the variability in cash flows of the hedged item affects net income. Gains and losses on derivatives are reclassified
immediately to net income from accumulated other comprehensive income when the hedged item is sold or terminated early, or when a hedged anticipated transaction is no longer expected to occur.

The
Company also enters into cash flow hedges and fair value hedges for activities subject to rate regulation. Any gains and losses arising from the changes in the fair
value of these hedges can be recovered through the tolls charged by the Company. As a result, any gains and losses are deferred as rate-regulated assets or liabilities on behalf of the
ratepayers. When the hedges are settled, the realized gains or losses are collected from or refunded to the ratepayers in subsequent years.

MANAGEMENT'S DISCUSSION AND ANALYSIS79

---



In
hedging the foreign currency exposure of a net investment in a self-sustaining foreign operation, the effective portion of foreign exchange gains and losses
on the hedging instruments is recognized in other comprehensive income and the ineffective portion is recognized in net
income. The amounts recognized previously in accumulated other comprehensive income are reclassified to net income in the event the Company settles or otherwise reduces its investment in a foreign
operation.

The
fair value of financial instruments and hedges, where fair value does not approximate carrying value, is primarily derived from market values adjusted for credit risk,
which can fluctuate greatly from period to period. These changes in fair value can result in variability in net income as a result of recording these changes in fair value through earnings. The risks
associated with fluctuations to earnings and cash flows for financial instruments and hedges are discussed further in the Risk Management and Financial Instruments section of this MD&A.

Depreciation and Amortization Expense

TransCanada's plant, property and equipment are depreciated on a straight-line basis over their estimated useful lives once they are ready for their intended use.
Pipeline and compression equipment are depreciated at annual rates ranging from one per cent to 25 per cent. Metering and other plant equipment are depreciated at various rates.
Major power generation and natural gas storage plant, equipment and structures in the Energy business are depreciated on a straight-line basis over estimated service lives at average
annual rates ranging from two per cent to ten per cent. Nuclear power generation assets under capital lease are initially recorded at the present value of minimum lease payments at the
inception of the lease and amortized on a straight-line basis over the shorter of their useful life and the remaining lease term. Other Energy equipment is depreciated at various rates.
Corporate plant, property and equipment are depreciated on a straight-line basis over estimated useful lives at average annual rates ranging from three per cent to
20 per cent.

Depreciation
expense in 2009 was $1,319 million (2008  $1,189 million;
2007  $1,179 million) and is recorded in Pipelines and Energy. In Pipelines, depreciation rates are approved by regulators when applicable and
depreciation expense is recoverable based on the cost of providing the services or products. If regulators permit recovery of depreciation through rates charged to customers, a change in the estimate
of the useful lives of plant, property and equipment in the Pipelines segment will have no material impact on TransCanada's net income but will directly affect funds generated from operations.

PPA
amortization expense of $58 million was recorded in Energy each year from 2007 through 2009. The initial payment for a PPA is deferred and amortized on a
straight-line basis over the term of the contract, with remaining terms ranging from eight years to 11 years.

Impairment of Long-Lived Assets and Goodwill

The Company reviews long-lived assets such as property, plant and equipment, and intangible assets for impairment whenever events or changes in circumstances
indicate the carrying value may not be recoverable. If the total of the estimated undiscounted future cash flows is less than the carrying value of the assets, an impairment loss is recognized for the
excess of the carrying value over the fair value of the assets.

Goodwill
is tested in the Pipelines and Energy segments for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be
impaired. An initial assessment is made by comparing the fair value of the operations, which includes goodwill, to the book values of each reporting unit. If this fair value is less than book value,
an impairment is indicated and a second test is performed to measure the amount of the impairment. In the second test, the implied fair value of the goodwill is calculated by deducting the fair value
of all tangible and intangible net assets of the reporting unit from the fair value determined in the initial assessment. If the carrying value of the goodwill exceeds the calculated implied fair
value of the goodwill, an impairment charge is recorded.

These
valuations are based on management's projections of future cash flows and, therefore, require estimates and assumptions with respect to:

80MANAGEMENT'S DISCUSSION AND ANALYSIS

Significant
changes in these assumptions could affect the Company's need to record an impairment charge.

ACCOUNTING CHANGES

CHANGES IN ACCOUNTING POLICIES FOR 2009

Rate-Regulated Operations

Effective January 1, 2009, the temporary exemption was withdrawn from the CICA Handbook Section 1100 "Generally Accepted Accounting Principles", which permitted
the recognition and measurement of assets and liabilities arising from rate regulation. In addition, Section 3465 "Income Taxes" was amended to require the recognition of future income tax
assets and liabilities for rate-regulated operations. In accordance with the CICA Handbook accounting hierarchy, the Company chose to adopt accounting policies consistent with the
U.S. Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) Topic 980 "Regulated Operations". As a result, TransCanada retained its current method of accounting
for its rate-regulated operations, except that the Company is required to recognize future income tax assets and liabilities, instead of using the taxes payable method, and records an
offsetting adjustment to regulatory assets and liabilities. As a result of adopting this accounting change, additional future income tax liabilities and a regulatory asset in the amount of
$1.4 billion were recorded January 1, 2009 in each of future income taxes and regulatory assets, respectively.

Adjustments
to the 2009 financial statements have been made in accordance with the transitional provisions for Section 3465, which required a cumulative adjustment in
the current period to future income taxes and regulatory assets. Restatement of prior periods' financial statements was not permitted under Section 3465.

Goodwill and Intangible Assets

Effective January 1, 2009, the Company adopted CICA Handbook Section 3064 "Goodwill and Intangible Assets", which replaced Section 3062 "Goodwill and Other
Intangible Assets". Section 3064 gives guidance on the recognition of intangible assets and on the recognition and measurement of internally developed intangible assets. In addition,
Section 3450 "Research and Development Costs" was withdrawn from the CICA Handbook. Adopting this accounting change did not have a material effect on the Company's financial statements.

Credit Risk and the Fair Value of Financial Assets and Financial Liabilities

Effective January 1, 2009, the Company adopted the accounting provisions of Emerging Issues Committee (EIC) Abstract EIC 173 "Credit Risk and the Fair Value of Financial
Assets and Financial Liabilities". Under EIC 173, an entity's own credit risk and the credit risk of its counterparties are taken into account in determining the fair value of financial assets
and financial liabilities, including derivative instruments. Adopting this accounting change did not have a material effect on the Company's financial statements.

FUTURE ACCOUNTING CHANGES

Business Combinations, Consolidated Financial Statements and Non-Controlling Interests

CICA Handbook Section 1582 "Business Combinations" is effective for business combinations with an acquisition date after January 1, 2011. This standard was
amended to require additional use of fair value measurements, recognition of

MANAGEMENT'S DISCUSSION AND ANALYSIS81

---



additional
assets and liabilities, and increased disclosure. Adopting the standard is expected to have a material effect on the way the Company accounts for future business combinations. Entities
adopting Section 1582 will also be required to adopt CICA Handbook Sections 1601 "Consolidated Financial Statements" and 1602 "Non-Controlling Interests". These standards
will require non-controlling interests to be presented as part of shareholders' equity on the balance sheet. In addition, the income statement of the controlling parent will include
100 per cent of the subsidiary's results and present the allocation between the controlling and non-controlling interests. These standards will be effective January 1,
2011, with early adoption permitted. The changes resulting from adopting Section 1582 will be applied prospectively and the changes from adopting Sections 1601 and 1602 will be
applied retrospectively.

International Financial Reporting Standards

The CICA's Accounting Standards Board announced that Canadian publicly accountable enterprises are required to adopt IFRS, as issued by the International Accounting Standards
Board (IASB), effective January 1, 2011. Effective January 1, 2011, the Company will begin reporting under IFRS.

TransCanada's
conversion plan includes obtaining skilled people, providing education and training, analyzing the impact on TransCanada of key differences between GAAP and
IFRS, and developing and executing a phased approach to conversion and implementation. The current status of key elements of TransCanada's conversion project is as follows:

Resources and Training

TransCanada has established an IFRS project team to support the conversion effort. The team conducts technical research and provides issue identification, training, work group
leadership, policy recommendations and implementation support. The project team is led by a multi-disciplinary Steering Committee that provides directional leadership for the conversion project and
assists in developing accounting policy recommendations. Management also updates the Audit Committee on the progress of the IFRS project at each Audit Committee meeting.

TransCanada's
IFRS training, which began in 2008, includes project awareness sessions, an annual comprehensive IFRS immersion course, topic specific courses and systems
training sessions. Throughout the project, IFRS training is being provided on an ongoing basis to TransCanada staff and directors affected by the conversion to ensure they are knowledgeable about new
IFRS developments.

Analysis of Differences Between IFRS and GAAP

TransCanada's conversion project is being executed using a risk-based methodology focusing on the significant differences between GAAP and IFRS. A
high-level diagnostic was completed in 2008 outlining the significant differences and rating each difference based on its expected level of significance to TransCanada. In making this
assessment, the technical accounting complexity, number of policy choices, estimated need for conversion resources and impact on systems were considered. The project team continues to assess the
differences between GAAP and IFRS and their significance to the Company.

The
differences between GAAP and IFRS that have been identified as significant to the Company are explained below. Several of the IFRS standards that are expected to be
applicable to TransCanada are in the process of being amended by the IASB. Amendments to existing standards are expected to continue until the January 1, 2011 effective date. TransCanada
actively monitors the IASB's schedule of projects, giving consideration to any
proposed changes, where applicable, in its assessment of differences between IFRS and GAAP. As a result of proposed changes to certain IFRS, together with the current stage of the Company's IFRS
project, TransCanada cannot reasonably quantify the full impact that adopting IFRS will have on its financial position and future results.

Rate-Regulated Activities

Under GAAP, TransCanada currently follows specific accounting policies unique to a rate-regulated business. In July 2009, the IASB issued an Exposure Draft
"Rate-Regulated Activities". Under the Exposure Draft, regulatory assets and regulatory liabilities will represent the expected present values of future revenues that are expected to be
recovered from or refunded to customers. Under GAAP, the Company measures these regulatory assets and regulatory liabilities on a historical cost basis in respect of future revenues that are expected
to be recovered from or refunded to customers.

82MANAGEMENT'S DISCUSSION AND ANALYSIS

---



The
Exposure Draft also outlines certain criteria an entity must meet to be within the scope of the new standard. The Company continues to assess the impact of developments regarding this exposure
draft, as they could have a significant effect on TransCanada's balance sheet and could result in increased income volatility.

Plant, Property and Equipment

Under GAAP, items of plant, property and equipment are depreciated on a straight-line basis over their estimated service lives. Under IFRS, significant components
of the same items of plant, property and equipment will be separately identified and depreciated over their respective estimated service life.

Joint Ventures

Under GAAP, TransCanada proportionately consolidates its share of the accounts of joint ventures in which the Company is able to exercise joint control and uses the equity
method of accounting for investments over which the Company is able to exercise significant influence.

The
IASB issued an Exposure Draft, which is expected to be effective in 2011, under which TransCanada would use the equity method of accounting for joint ventures in which
the Company is able to exercise joint control or significant influence, but not sole control. For joint operations in which the Company is able to exercise joint control, TransCanada would record its
proportionate share of the assets, liabilities and related revenues and expenses, as well as expenses or liabilities the Company would incur directly on behalf of the assets.

Provisions

Under GAAP, the scope and timing of asset retirements related to regulated natural gas pipelines and hydroelectric power plants is uncertain. As a result, the Company has not
recorded an amount for asset retirement obligations related to these assets with the exception of certain abandoned facilities.

Under
IFRS, TransCanada would be required to record obligations relating to the retirement of its regulated pipelines where a legal, contractual or constructive obligation
currently exists. The Company is assessing its ability to reliably estimate the cost to abandon these assets in the future, where applicable.

Employee Benefits

Under GAAP, past service costs relating to the Company's defined benefit pension plans are recognized over the expected average remaining service life of the employees. Under
IFRS, past service costs would be recognized on a straight-line basis over the average remaining vesting period.

Under
GAAP, actuarial gains and losses are deferred and amortized using a "corridor" approach. Under IFRS, there are three alternatives for recognizing actuarial gains and
losses. These gains or losses can be deferred and amortized subject to certain provisions that differ slightly from GAAP, recognized in profit and loss in the period they are incurred or recognized in
other comprehensive income in the period they are incurred. The Company is currently assessing the IFRS alternatives.

Leases

Under GAAP and IFRS, leases that transfer to the Company substantially all the risks and rewards incidental to ownership of the leased item are capitalized at the commencement
of the lease term. GAAP prescribes specific thresholds for evaluating whether substantially all the risks and rewards incidental to ownership of the leased item are transferred, while IFRS does not
contain such specific thresholds. The Company is currently assessing its lease contracts, including contingent lease payments, under IFRS.

Financial Instruments

Under GAAP, contracts that meet specific scope exemptions or do not meet the definition of a derivative as they do not have a specified notional amount, are not subject to the
recognition and measurement criteria for financial instruments. The Company is currently assessing these contracts to determine whether they are subject to IFRS recognition and measurement criteria
for financial instruments.

MANAGEMENT'S DISCUSSION AND ANALYSIS83

---



Impairment of Non-Current Assets

The Company reviews non-current assets, such as plant, property and equipment and intangible assets with a definite, useful life, for indicators of impairment at
each reporting date. Tests for impairment are performed if there is an indication that the carrying value of the assets may not be recoverable.

The
method of determining a potential impairment loss is slightly different under GAAP than under IFRS and the Company is assessing the impact of the difference
on TransCanada.

Impairment of Goodwill

Under GAAP, an initial impairment assessment of goodwill is made by comparing the fair value of the operations, which includes goodwill, to the book values of each reporting
unit. If the fair value is less than the book value, an impairment is indicated and a second test is performed to measure the amount of the impairment. In the second test, the implied fair value of
the goodwill is calculated by deducting the fair value of all tangible and intangible net assets of the reporting unit from the fair value determined in the initial assessment. If the carrying value
of the goodwill exceeds the calculated implied fair value of the goodwill, an impairment charge is recorded. Under IFRS, for the purposes of impairment testing, goodwill acquired in a business
combination is allocated to cash-generating units that are expected to benefit from the synergies of the combination. An impairment loss is recognized when the recoverable amount of
the cash-generating unit is less than the carrying amount, including goodwill.

Conversion Implementation

During the conversion implementation phase, TransCanada will continue to execute required changes to its information systems and business processes, disclosure controls and
internal controls over financial reporting. Required changes continue to be identified on a concurrent basis with the Company's analysis of significant GAAP differences. TransCanada is also assessing
the impact of transitioning to IFRS on its financial statement presentation and disclosures. The Company is monitoring and updating the effect of IFRS on its internal controls over financial reporting
and does not expect any significant obstacles.

Information
systems, including information technology systems and computer software, are being changed to accommodate IFRS. TransCanada's accounting system has been expanded
to enable the production of
multiple financial statements based on reporting under both GAAP and IFRS, facilitating the requirement in 2010 to report GAAP financial information while tracking IFRS financial information. Other
information system changes include allowing for the capture of new data, creation and deletion of accounts, modifications to existing systems relating to calculations, consolidations, models and
reports, and other revisions to accounting software to accommodate IFRS accounting and reporting requirements.

Factors Impacting Quarterly Financial Information

In Pipelines, which consists primarily of the Company's investments in regulated pipelines and regulated natural gas storage facilities, annual revenues and net income
fluctuate over the long term based on regulators' decisions and negotiated settlements with shippers. Generally, quarter-over-quarter revenues and net income during any
particular fiscal year remain relatively stable with fluctuations resulting from adjustments being recorded due to regulatory decisions and negotiated settlements with shippers, seasonal fluctuations
in short-term throughput volumes on U.S. pipelines, acquisitions and divestitures, and developments outside of the normal course of operations.

In
Energy, which consists primarily of the Company's investments in electrical power generation plants and non-regulated natural gas storage facilities,
quarter-over-quarter revenues and net income are affected by seasonal weather conditions, customer demand, market prices, capacity payments, planned and unplanned plant
outages, acquisitions and divestitures, certain fair value adjustments and developments outside of the normal course of operations.

Significant
developments that impacted EBIT and net income in 2009 and 2008 were as follows:

MANAGEMENT'S DISCUSSION AND ANALYSIS87

---



TransCanada's net income was $387 million and net income applicable to common shares was $381 million or $0.56 per
share in fourth quarter 2009 compared to $277 million or $0.47 per share in fourth quarter 2008. The $104 million increase in net income applicable to common shares reflected:

The
increase in earnings per share in fourth quarter 2009 from fourth quarter 2008 was partially offset by a 14 per cent increase in the average number of
common shares outstanding, following the Company's issuance of 58.4 million and 35.1 million common shares in second quarter 2009 and fourth quarter 2008, respectively.

Comparable
earnings in fourth quarter 2009 increased $57 million or $0.02 per share to $328 million or $0.48 per share, compared to $271 million or
$0.46 per share for the same period in 2008. Comparable earnings in fourth quarter 2009 excluded the $18 million after tax dilution gain resulting from TransCanada's reduced ownership in
PipeLines LP and the $30 million of favourable income tax adjustments. Comparable earnings in fourth quarter 2009 and 2008 also excluded net unrealized after tax gains of
$5 million ($7 million pre-tax) and $6 million ($7 million pre-tax), respectively, resulting from changes in the fair value of proprietary natural
gas inventory in storage and natural gas forward purchase and sale contracts.

Pipelines
comparable EBIT was $488 million in fourth quarter 2009 compared to $556 million for the same period in 2008. Comparable EBIT excluded the
$29 million pre-tax dilution gain resulting from a reduction in TransCanada's ownership interest in PipeLines LP following PipeLines LP's public issuance of common
units in fourth quarter 2009.

Canadian
Mainline's net income for fourth quarter 2009 decreased $2 million to $72 million from $74 million for the same period in 2008. Net income for
fourth quarter 2009 reflected a lower average investment base and a lower ROE set by the NEB at 8.57 per cent in 2009 compared to 8.71 per cent in 2008, partially offset by
higher OM&A cost savings.

Canadian
Mainline's EBITDA for fourth quarter 2009 of $282 million decreased $18 million compared to the same period in 2008 primarily due to lower revenues as
a result of a recovery of lower income taxes and a lower overall return on average investment base in the 2009 tolls, partially offset by higher OM&A cost savings.

The
Alberta System's net income was $45 million in fourth quarter 2009 compared to $48 million for the same period in 2008. Earnings in 2009 and 2008 reflected
the impact of the 2008-2009 Revenue Requirement Settlement approved by the AUC in December 2008 and by the NEB in December 2009.

88MANAGEMENT'S DISCUSSION AND ANALYSIS

---



The
Alberta System's EBITDA was $193 million in fourth quarter 2009 compared to $152 million for the same period in 2008. The increase reflected higher
revenues as a result of the recovery of higher depreciation and income taxes, partially offset by lower settlement earnings.

EBITDA
from Other Canadian Pipelines was $15 million in fourth quarter 2009 compared to $11 million for the same period in 2008. The increase was primarily due
to an adjustment to TQM's cost of capital for 2009.

ANR's
EBITDA in fourth quarter 2009 was $84 million compared to $99 million for the same period in 2008. The decrease in EBITDA was primarily due to the
negative impact of a weaker U.S. dollar.

GTN's
EBITDA in fourth quarter 2009 decreased $9 million from the same period in 2008 primarily due to the negative impact of a weaker U.S. dollar and the sale
of North Baja to PipeLines LP.

EBITDA
for the remainder of the U.S. Pipelines was $132 million in fourth quarter 2009 compared to $144 million for the same period in 2008. The
decrease was primarily due to the negative impact of a weaker U.S. dollar on U.S. Pipelines operations, partially offset by the acquisition of North Baja by PipeLines LP.

Pipelines
business development comparable EBITDA losses increased $27 million in fourth quarter 2009 compared to the same period in 2008 primarily due to increased
business development costs related to the Alaska pipeline project.

Energy's
comparable EBIT was $162 million in fourth quarter 2009 compared to $217 million in fourth quarter 2008. Comparable EBIT in fourth quarter 2009 and
fourth quarter 2008 excluded net unrealized gains of $7 million in each period resulting from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward
purchase and sale contracts.

Power's EBITDA of $61 million and power revenues of $203 million in fourth quarter 2009 decreased $67 million and $95 million,
respectively, compared to the same period in 2008. These decreases were primarily due to lower earnings from the Alberta power portfolio resulting from lower overall realized power prices on lower
volumes of power sold. The reduction in power prices and sales volumes reflected reduced demand for electricity in Alberta as a result of the North American economic slowdown. Average spot market
power prices in Alberta decreased 51 per cent or $49 per MWh in fourth quarter 2009 compared to fourth quarter 2008.

Eastern
Power's EBITDA of $56 million in fourth quarter 2009 increased $13 million compared to the same period in 2008. These increases were primarily due to
incremental earnings from Portlands Energy which went into service in April 2009.

TransCanada's
proportionate share of Bruce Power's comparable EBITDA of $70 million in fourth quarter 2009 was consistent with fourth quarter 2008. Increased revenues
from higher realized prices and an
annual lease expense reduction at Bruce B were offset by higher non-lease operating expenses and lower volumes caused by an increase in outage days.

TransCanada's
proportionate share of Bruce A's comparable EBITDA decreased $28 million to a loss of $29 million in fourth quarter 2009 compared to a
loss of $1 million in fourth quarter 2008. The higher loss was due to decreased volumes and higher operating costs as a result of an unplanned extension of the two planned outages which were
rescheduled to September 2009 from March 2009. Bruce A's plant availability in fourth quarter 2009 was 47 per cent as a result of 84 outage days compared to
an availability of 62 per cent and 63 outage days in the same period in 2008.

TransCanada's
proportionate share of Bruce B's comparable EBITDA increased $28 million to $99 million in fourth quarter 2009 compared to fourth quarter
2008 primarily due to higher realized prices resulting from the recognition of payments received pursuant to the floor price mechanism in Bruce B's contract with the OPA, as well as a reduction
in annual lease expense. Provisions in the Bruce B lease agreement with Ontario Power Generation allow for a reduction in annual lease expense if the annual Ontario spot price for electricity
was less than $30 per MWh.

MANAGEMENT'S DISCUSSION AND ANALYSIS89

---



U.S. Power's
comparable EBITDA for fourth quarter 2009 of $29 million decreased $21 million compared to the same period in 2008. The decrease was
primarily due to lower overall realized power prices and the impact of a weaker U.S. dollar, partially offset by incremental revenue realized on contract sales in New England. While
average spot market power prices in New England decreased in fourth quarter 2009 compared to fourth quarter 2008, the majority of U.S. Power's sales volumes were sold at contracted
prices.

Natural
Gas Storage's comparable EBITDA in fourth quarter 2009 was $49 million compared to $34 million for the same period in 2008. The $15 million
increase was primarily due to increased third party storage revenues as a result of higher realized seasonal natural gas price spreads. Comparable EBITDA excluded net unrealized gains of
$7 million in fourth quarter 2009 (2008  gains of $7 million), resulting from changes in the fair value of proprietary natural gas inventory in
storage and natural gas forward purchase and sale contracts.

Corporate
EBIT losses in fourth quarter 2009 were $28 million compared to losses of $33 million for the same period in 2008. The decreases in EBIT losses were
primarily due to lower support service costs in fourth quarter 2009.

Interest
expense in fourth quarter 2009 decreased $142 million to $184 million from $326 million in fourth quarter 2008. The decrease reflected
increased capitalized interest to finance the Company's larger capital growth program in 2009, primarily due to Keystone construction, and a decrease in U.S. dollar-denominated interest expense
due to the impact of a weaker U.S. dollar in fourth quarter 2009 compared to fourth
quarter 2008. Interest expense also decreased due to reduced losses in fourth quarter 2009 compared to 2008 from changes in the fair value of derivatives used to manage the Company's exposure to
interest rate fluctuations. These decreases were partially offset by incremental interest expense on new debt issues of US$2.0 billion in January 2009 and $700 million in
February 2009.

Interest
Income and Other in fourth quarter 2009 was income of $22 million compared to an expense of $4 million for the same period in 2008. The increase in
income of $26 million in fourth quarter 2009 was primarily due to the positive impact of a weaker U.S. dollar on working capital balances in fourth quarter 2009 and higher gains from
changes in the fair value of derivatives used to manage the Company's exposure to foreign exchange rate fluctuations. These increases were partially offset by lower interest income due to lower
interest rates.

Income
Taxes were $67 million in fourth quarter 2009 compared to $95 million for the same period in 2008. The decrease was primarily due to positive income tax
adjustments in 2009, including a $30 million favourable adjustment resulting from a reduction in the Province of Ontario's corporate income tax rates, partially offset by higher
pre-tax income.

92MANAGEMENT'S DISCUSSION AND ANALYSIS

---





|Report of
Management |  | The consolidated financial statements included in this Annual Report are the responsibility of the management of TransCanada Corporation (TransCanada or the Company) and have been approved by the Board of Directors of the
Company. These consolidated financial statements have been prepared by management in accordance with generally accepted accounting principles (GAAP) in Canada and include amounts that are based on estimates and judgements. Financial information
contained elsewhere in this Annual Report is consistent with the consolidated financial statements.
Management's Discussion and Analysis in this Annual Report has been prepared by management based on the Company's financial results prepared in accordance with GAAP. It compares the Company's financial and operating performance in 2009
to that in 2008 and should be read in conjunction with the consolidated financial statements and accompanying notes. In addition, it highlights significant changes between 2008 and 2007.
Management has designed and maintains a system of internal controls over financial reporting, including a program of internal audits. Management believes these controls provide reasonable assurance that financial records are reliable and
form a proper basis for the preparation of financial statements. The internal controls over financial reporting include management's communication to employees of policies that govern ethical business conduct.
Under the supervision and with the participation of the President and Chief Executive Officer and the Chief Financial Officer, management conducted an evaluation of the effectiveness of its internal controls over financial reporting
based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management concluded, based on its evaluation, that internal controls over financial
reporting are effective as of December 31, 2009 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes.The Board of Directors has appointed an Audit Committee consisting of independent, non-management directors. The Audit Committee meets with management at least five times a year and meets independently with the internal and external
auditors and as a group to review any significant accounting, internal control and auditing matters in accordance with the terms of the Charter of the Audit Committee, which is set out in the Annual Information Form. The Audit Committee's
responsibilities include overseeing management's performance in carrying out its financial reporting responsibilities and reviewing the Annual Report, including the consolidated financial statements, before the consolidated financial statements are
submitted to the Board of Directors for approval. The internal and independent external auditors are able to access the Audit Committee without the requirement to obtain prior management approval.
The Audit Committee approves the terms of engagement of the independent external auditors and reviews the annual audit plan, the Auditors' Report and the results of the audit. It also recommends to the Board of Directors the firm of
external auditors to be appointed by the shareholders.
The shareholders have appointed KPMG LLP as independent external auditors to express an opinion as to whether the consolidated financial statements present fairly, in all material respects, the Company's consolidated financial
position, results of operations and cash flows in accordance with GAAP. The report of KPMG LLP outlines the scope of its examination and its opinion on the consolidated financial statements.

equity and cash flows for each of the years in the three year period ended December 31, 2009. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial
statements based on our audits.
We conducted our audits in accordance with Canadian generally accepted auditing standards and in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan

An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.
In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2009 and 2008 and the results of its operations and its cash flows for each
of the years in the three year period ended December 31, 2009 in accordance with Canadian generally accepted accounting principles.

NOTE 2    ACCOUNTING POLICIES

The Company's consolidated financial statements have been prepared by management in accordance with GAAP. Amounts are stated in Canadian dollars unless otherwise indicated.
Certain comparative figures have been reclassified to conform with the current year's presentation.

In
preparing these financial statements, TransCanada is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities,
revenues and expenses as the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgment in making these
estimates and
assumptions. In the opinion of management, these consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company's
significant accounting policies summarized below.

102NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS

Basis of Presentation

The consolidated financial statements include the accounts of TransCanada and its subsidiaries. The Company consolidates its interest in entities over which it is able to
exercise control. To the extent there are interests owned by other parties, the other parties' interests are included in Non-Controlling Interests. TransCanada proportionately consolidates
its share of the accounts of joint ventures in which the Company is able to exercise joint control. TransCanada uses the equity method of accounting for investments over which the Company is able to
exercise significant influence.

Regulation

The Canadian regulated natural gas pipelines are subject to the authority of the National Energy Board (NEB) of Canada. Effective April 2009, the Alberta System became
subject to the authority of the NEB. Prior to that date the Alberta System was regulated by the Alberta Utilities Commission (AUC). The natural gas pipelines and regulated storage assets in the
U.S. are subject to the authority of the U.S. Federal Energy Regulatory Commission (FERC). These natural gas transmission operations are regulated with respect to construction,
operations and the determination of tolls. The timing of recognition of certain revenues and expenses in these regulated businesses may differ from that otherwise expected under GAAP to appropriately
reflect the economic impact of the regulators' decisions regarding revenues and tolls.

Revenue Recognition

Pipelines

In the Pipelines segment, revenues from Canadian operations subject to rate regulation are recognized in accordance with decisions made by the NEB. Revenues from
U.S. operations subject to rate regulation are recorded in accordance with FERC rules and regulations. The Company's natural gas pipeline revenues are generally based on quantity of gas
delivered or contracted capacity. Revenues are recognized on firm contracted capacity over the contract period. For interruptible or volumetric-based services, revenues are recorded when physical
delivery is made. The Company's natural gas pipelines that are subject to rate proceedings may have to refund a portion of the revenues they collect depending on the outcome of future rate
proceedings. Revenues from non-regulated operations are recorded when products have been delivered or services have been performed.

Energy

i)      Power

Revenues from the Company's power business are primarily derived from the sale of electricity through energy marketing activities and from the sale of unutilized natural gas
fuel, which are recorded at the time of delivery. Revenues also include capacity payments and ancillary services, which are earned monthly, and revenues earned through the use of energy derivative
contracts. The accounting for energy derivative contracts is described in the Financial Instruments section of this note.

ii)     Natural Gas Storage

Revenues earned from providing natural gas storage services are recognized in accordance with the terms of the natural gas storage contracts. Revenues earned on the sale of
proprietary natural gas are recorded in the month of delivery. Forward contracts for the purchase or sale of natural gas, as well as proprietary natural gas inventory held in storage, are recorded at
fair value with changes in fair value recorded in Revenues.

Cash and Cash Equivalents

The Company's cash and cash equivalents consist of cash and highly liquid short-term investments with original maturities of three months or less and are recorded at
cost, which approximates fair value.

Inventories

Inventories primarily consist of materials and supplies, including spare parts, and fuel, and are carried at the lower of average cost and net realizable value. The Company
values its proprietary natural gas inventory held in storage at fair value, as measured by a weighted average of forward prices for the following four months less selling costs. To record inventory at
fair value, TransCanada has designated its natural gas storage business as a broker/trader business that purchases and sells natural gas on a back-to-back basis. The Company
records its net proprietary natural gas storage sales and purchases in Revenues. All changes in the fair value of proprietary natural gas inventory held in storage are reflected in Inventories
and Revenues.

STATEMENTS103

Plant, Property and Equipment

Pipelines

Plant, property and equipment of the Pipelines segment are carried at cost. Depreciation is calculated on a straight-line basis once the assets are ready for their
intended use. Pipeline and compression equipment are depreciated at annual rates ranging from one per cent to 25 per cent and metering and other plant equipment are depreciated at
various rates. The cost of regulated pipelines includes an allowance for funds used during construction (AFUDC) consisting of a debt component and an equity component based on the rate of return on
rate base approved by regulators. This allowance is reflected as an increase in the cost of the assets on the Balance Sheet. Interest is capitalized during construction of non-regulated
pipelines. The equity component of AFUDC is a non-cash expenditure.

When
regulated pipelines retire plant, property and equipment from service, the original book cost is removed from the gross plant amount and recorded as a reduction to
Accumulated Depreciation. Costs incurred to remove a plant from service, net of any salvage proceeds, are also recorded in Accumulated Depreciation.

Energy

Major power generation and natural gas storage plant, equipment and structures in the Energy segment are recorded at cost and depreciated once the assets are ready for their
intended use on a straight-line basis over estimated service lives at average annual rates ranging from two per cent to ten per cent. Nuclear power generation assets under
capital lease are recorded initially at the present value of minimum lease payments at the inception of the lease and amortized on a straight-line basis over the shorter of their useful
life and the remaining lease term. Other equipment is depreciated at various rates. The cost of major overhauls of equipment is capitalized and depreciated over the estimated service lives. Interest
is capitalized on facilities under construction.

Corporate

Corporate plant, property and equipment are recorded at cost and depreciated on a straight-line basis over estimated useful lives at average annual rates ranging
from three to 20 per cent.

Impairment of Long-Lived Assets

The Company reviews long-lived assets such as plant, property and equipment, and intangible assets for impairment whenever events or changes in circumstances
indicate the carrying value may not be recoverable. If the total of the estimated undiscounted future cash flows is less than the carrying value of the assets, an impairment loss is recognized for the
excess of the carrying value over the fair value of the assets.

Acquisitions and Goodwill

The Company accounts for business acquisitions using the purchase method of accounting and, accordingly, the assets and liabilities of the acquired entities are recorded at
their estimated fair value at the date of acquisition. Goodwill is not amortized and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset
might be impaired. An initial assessment is made by comparing the fair value of the operations, which includes goodwill, to the book value of each reporting unit. If the fair value is less than book
value, an impairment is indicated and a second test is performed to measure the amount of the impairment. In the second test, the implied fair value of the goodwill is calculated by deducting the fair
value of all tangible and intangible net assets of the reporting unit from the fair value determined in the initial assessment. If the carrying value of the goodwill exceeds the calculated implied
fair value of the goodwill, an impairment charge is recorded.

Power Purchase Arrangements

A PPA is a long-term contract for the purchase or sale of power on a predetermined basis. The initial payments for the PPAs were deferred and amortized on a
straight-line basis over the term of the contracts, which expire in 2017 and 2020. The PPAs under which TransCanada buys power are accounted for as operating leases. A portion of these
PPAs has been subleased to third parties under similar terms and conditions. The subleases are accounted for as operating leases and TransCanada records the margin earned from the subleases as a
component of Revenues.

Stock Options

TransCanada's Stock Option Plan permits options to be awarded to certain employees, including officers, to purchase common shares. The contractual life of options granted in
2003 and thereafter and options granted prior to 2003 is seven years and ten years, respectively. The Company uses the Black-Scholes model to determine fair value of the options on their grant
date. Options may be exercised at a price determined at the time the option is awarded and vest 33.3 per cent on the anniversary date in each of the three years following the award.
Forfeiture of stock options results from their expiration or upon resignation or retirement of the option holder or upon termination of the option holder's employment. Stock options become null and
void upon forfeiture. The Company records compensation expense over the

three year
vesting period, assuming a 15 per cent forfeiture rate, with an offset to Contributed Surplus. This charge is reflected in the results of Corporate. Upon exercise of
stock options, adjusted for stock options forfeited, amounts originally recorded against Contributed Surplus are reclassified to Common Shares.

Income Taxes

The Company uses the liability method of accounting for income taxes, which requires the recognition of future income tax assets and liabilities for the future tax consequences
attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future income tax assets and liabilities are measured
using enacted or substantively enacted tax rates at the Balance Sheet date that are anticipated to apply to taxable income in the years in which temporary differences are anticipated to be recovered
or settled. Changes to these balances are recognized in income in the period during which they occur.

Prior
to January 1, 2009, the Company used the taxes payable method of accounting for income taxes for tollmaking purposes for Canadian regulated natural gas
transmission operations, as prescribed by regulators. This method was also used for accounting purposes as permitted by GAAP, since there was a reasonable expectation that future taxes payable would
be included in future costs of service and recorded in revenues at that time. The liability method of accounting for income taxes continues to be used for all of the Company's other operations.

Canadian
income taxes are not provided on the unremitted earnings of foreign investments that the Company does not intend to repatriate in the foreseeable future.

Foreign Currency Translation

The Company's foreign operations are self-sustaining and are translated into Canadian dollars using the current rate method. Under this method, assets and
liabilities are translated at period-end exchange rates and items included in the Consolidated Statements of Income, Shareholders' Equity, Comprehensive Income, Accumulated Other
Comprehensive Income and Cash Flows are translated at the exchange rates in effect at the time of the transaction. Translation adjustments are reflected in Other Comprehensive Income.

Exchange
gains or losses on monetary assets and liabilities are recorded in income except for exchange gains or losses on the principal amounts of foreign currency debt
related to the Alberta System, Foothills and Canadian Mainline, which are deferred until they are refunded or recovered in tolls, as permitted by regulatory bodies.

Financial Instruments

The Company initially records all financial instruments on the Balance Sheet at their fair value. Subsequent measurement of the financial instruments is based on their
classification. Financial assets are classified into the following categories: held for trading, available for sale, held-to-maturity investments and loans and receivables.
Financial liabilities are classified as held for trading or other financial liabilities.

Held-for-trading
derivative financial assets and liabilities consist of swaps, options, forwards and futures. A financial asset or liability may be
designated as held for trading when it is entered into with the intention of generating a profit. The Company has not designated any non-derivative financial assets or liabilities as held
for trading. Commodity held-for-trading financial instruments are initially recorded at their fair value and changes to fair value are included in Revenues. Changes in the fair
value of interest rate and foreign exchange rate held-for-trading instruments are recorded in Interest Expense and in Interest Income and Other, respectively. Realized gains
and losses are included in the same financial category as their underlying position upon settlement of the financial instrument.

The
available-for-sale classification includes non-derivative financial assets that are designated as available for sale or are not
included in any of the other three classifications. TransCanada's available-for-sale financial instruments include fixed-income securities held for self-insurance.
These instruments are accounted for initially at their fair value and changes to fair value are recorded through Other Comprehensive Income. Income from the settlement of
available-for-sale financial assets is included in Interest Income and Other.

The
held-to-maturity classification consists of non-derivative financial assets that are accounted for at their amortized cost using the
effective interest method. The Company does not have any held-to-maturity financial assets.

Trade
receivables, loans and other receivables with fixed or determinable payments that are not quoted in an active market are classified as "loans and receivables" and are
measured at amortized cost using the effective interest method, net of any impairment. The Company's loans and receivables include trade accounts receivable, interest and
non-interest-bearing third-party loans and notes receivable. Interest and other income earned from these financial assets are recorded in Interest Income and Other.

Other
financial liabilities consist of liabilities not classified as held for trading. Items in this financial instrument category are recognized at amortized cost using the
effective interest method. Interest expense is included in Interest Expense and in Interest Expense of Joint Ventures.

STATEMENTS105

The
Company uses derivatives and other financial instruments to manage its exposure to changes in foreign currency exchange rates, interest rates and energy commodity
prices. The Company also uses a combination of derivatives and U.S. dollar-denominated debt to manage the foreign currency exposure of its foreign operations.

All
derivatives are recorded on the Balance Sheet at fair value, with the exception of non-financial derivatives that were entered into and continue to be held
for the purpose of receipt or delivery in accordance with the Company's expected purchase, sale or usage requirements. Changes in fair value of derivatives that are not designated in a hedging
relationship are recorded in Net Income. Derivatives used in hedging relationships are discussed further in the Hedges section of this note.

Derivatives
embedded in other financial instruments or contracts (host instrument) are recorded as separate derivatives and are measured at fair value if the economic
characteristics of the embedded derivative are not closely related to the host instrument, the terms of the embedded derivative are the same as those of a stand-alone derivative and the total contract
is not held for trading or accounted for at fair value. Changes in the fair value of embedded derivatives that are recorded separately are included in Net Income.

The
recognition of gains and losses on the derivatives for the Alberta System, Foothills and Canadian Mainline exposures is determined through the regulatory process. The
gains and losses on derivatives accounted for as part of rate-regulated accounting are deferred in Regulatory Assets or Regulatory Liabilities.

Transaction
costs are defined as incremental costs that are directly attributable to the acquisition, issue or disposal of a financial instrument. The Company offsets
long-term debt transaction costs against the associated debt and amortizes these costs using the effective interest method for all costs except those related to the Canadian regulated
pipelines, which continue to be amortized on a straight-line basis in accordance with the provisions of tolling mechanisms.

The
Company records the fair value of its portion of material joint and several guarantees. The fair value of these guarantees is estimated by discounting the cash flows
that would be incurred by the Company if letters of credit were used in place of the
guarantees. Guarantees are recorded as an increase to an investment account, Property, Plant and Equipment or a charge to Net Income, and a corresponding liability is recorded in Deferred Amounts.

Hedges

The Company applies hedge accounting to arrangements that qualify for hedge accounting treatment, which include fair value and cash flow hedges, and hedges of foreign currency
exposures of net investments in self-sustaining foreign operations. Documentation is prepared at the inception of each hedging arrangement in order to qualify for hedge accounting
treatment. In addition, the Company performs an assessment of effectiveness at the inception of the contract and at each reporting date. Hedge accounting is discontinued prospectively when the hedging
relationship ceases to be effective or the hedging or hedged items cease to exist as a result of maturity, expiry, sale, termination, cancellation or exercise.

In
a fair value hedging relationship, the carrying value of the hedged item is adjusted for changes in fair value attributable to the hedged risk. The changes in fair value
are recognized in Net Income. Changes in the fair value of the hedged item, to the extent that the hedging relationship is effective, are offset by changes in the fair value of the hedging item, which
are also recorded in Net Income. Changes in the fair value of foreign exchange and interest rate fair value hedges are recorded in Interest Income and Other and Interest Expense, respectively. When
hedge accounting is discontinued, the carrying value of the hedged item is no longer adjusted and the cumulative fair value adjustments to the carrying value of the hedged item are amortized to Net
Income over the remaining term of the original hedging relationship.

In
a cash flow hedging relationship, the effective portion of the change in the fair value of the hedging derivative is initially recognized in Other Comprehensive Income,
while any ineffective portion is recognized in Net Income in the same financial category as the underlying transaction. When hedge accounting is discontinued, the amounts recognized previously in
Accumulated Other Comprehensive Income are reclassified to Revenues, Interest Expense and Interest Income and Other, as appropriate, during the periods when the variability in cash flows of the hedged
item affects Net Income or as the original hedged item settles. Gains and losses on derivatives are reclassified immediately to Net Income from Accumulated Other Comprehensive Income when the hedged
item is sold or terminated early, or when an anticipated transaction is no longer expected to occur.

The
Company also enters into cash flow hedges and fair value hedges for activities subject to rate regulation. The gains and losses arising from changes in the fair value of
these hedges can be recovered through the tolls charged by the Company. As a result, these gains and losses are deferred as rate-regulated assets or liabilities on behalf of the
ratepayers. When the hedges are settled, the realized gains or losses are collected from or refunded to the ratepayers in subsequent years.

In
hedging the foreign currency exposure of a net investment in a self-sustaining foreign operation, the effective portion of foreign exchange gains and losses
on the hedging instruments is recognized in Other Comprehensive Income and the ineffective portion is recognized in Net Income. The amounts recognized previously in Accumulated Other Comprehensive
Income are reclassified to Net Income in the event the Company settles its hedging instruments or reduces its investment in a foreign operation.

Asset Retirement Obligations

The Company recognizes the fair value of a liability for an asset retirement obligation in the period in which it is incurred, when a legal obligation exists and a reasonable
estimate of fair value can be made. The fair value is added to the carrying amount of the associated asset and the liability is accreted at the end of each period through charges to operating
expenses.

The
scope and timing of asset retirements related to regulated natural gas pipelines and hydroelectric power plants is uncertain. As a result, the Company has not recorded
an amount for asset retirement obligations related to these assets, with the exception of certain abandoned facilities. With respect to the nuclear assets leased by Bruce Power, the Company has not
recorded an amount for asset retirement obligations, as Bruce Power leases the assets and the lessor is responsible for decommissioning liabilities under the lease agreement.

Environmental Liabilities

The Company records liabilities on an undiscounted basis for environmental remediation efforts that are likely to occur and where the cost can be reasonably estimated. The
estimates, including associated legal costs, are based on available information using existing technology and enacted laws and regulations. The estimates are subject to revision in future periods
based on actual costs incurred or new circumstances. Amounts expected to be recovered from other parties, including insurers, are recorded as an asset separate from the associated liability.

Emission
allowances or credits purchased for compliance are recorded on the Balance Sheet at historical cost and expensed when they are retired. Compliance payments are
expensed when incurred. Allowances granted to or internally generated by TransCanada are not attributed a value for accounting purposes. When required, TransCanada accrues emission liabilities on the
Balance Sheet upon the generation or sale of power using the best estimate of the amount required to settle the obligation. Allowances or credits not used for compliance are sold and recorded
in Revenues.

Employee Benefit and Other Plans

The Company sponsors defined benefit pension plans (DB Plans), defined contribution plans (DC Plans), a Savings Plan and other post-employment benefit
plans. Contributions made by the Company to the DC Plans and Savings Plan are expensed when incurred. The cost of the DB Plans and other post-employment benefits received by employees is
actuarially determined using the projected benefit method pro-rated based on service and management's best estimate of expected plan investment performance, salary escalation, retirement
age of employees and expected health care costs.

The
DB Plans' assets are measured at fair value. The expected return on the DB Plans' assets is determined using market-related values based on a five year moving average
value for all of the DB Plans' assets. Past service costs are amortized over the expected average remaining service life of the employees. Adjustments arising from plan amendments are amortized on a
straight-line basis over the average remaining service period of employees active at the date of amendment. The excess of net actuarial gains or losses over ten per cent of the
greater of the benefit obligation and the market-related value of the DB Plans' assets, if any, is amortized over the average remaining service period of the active employees. When the restructuring
of a benefit plan gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement.

The
Company has medium-term incentive plans, under which payments are made to eligible employees. The expense related to these incentive plans is accounted for
on an accrual basis. Under these plans, benefits vest when certain conditions are met, including the employees' continued employment during a specified period and achievement of specified corporate
performance targets.

Certain
of the Company's joint ventures sponsor DB Plans. The Company records its proportionate share of expenses, funding contributions and accrued benefit assets and
liabilities related to these plans.

NOTE 3    ACCOUNTING CHANGES

Changes in Accounting Policies for 2009

Rate-Regulated Operations

Effective January 1, 2009, the temporary exemption was withdrawn from the Canadian Institute of Chartered Accountants (CICA) Handbook Section 1100 "Generally
Accepted Accounting Principles", which permitted the recognition and measurement of assets and liabilities arising from rate regulation. In addition, Section 3465 "Income Taxes" was amended to
require the recognition of future income tax assets and liabilities for rate-regulated operations. In accordance with the CICA Handbook accounting hierarchy, the Company chose to adopt
accounting policies consistent with the U.S. Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) Topic 980 "Regulated Operations". As a result, TransCanada
retained its current method of accounting for its rate-regulated operations, except that the Company is required to recognize future income tax assets and liabilities, instead of using the
taxes payable method, and records an offsetting adjustment to regulatory assets and liabilities. As a result of adopting this accounting change, additional future income tax liabilities and a
regulatory asset in the amount of $1.4 billion were recorded January 1, 2009 in each of Future Income Taxes and Regulatory Assets.

STATEMENTS107

Adjustments
to the 2009 financial statements have been made in accordance with the transitional provisions for Section 3465, which required a cumulative adjustment in
the current period to Future Income Taxes and Regulatory Assets. Restatement of prior periods' financial statements was not permitted under Section 3465.

Goodwill and Intangible Assets

Effective January 1, 2009, the Company adopted CICA Handbook Section 3064 "Goodwill and Intangible Assets", which replaced Section 3062 "Goodwill and Other
Intangible Assets". Section 3064 gives guidance on the recognition of intangible assets and on the recognition and measurement of internally developed intangible assets. In addition,
Section 3450 "Research and Development Costs" was withdrawn from the CICA Handbook. Adopting this accounting change did not have a material effect on the Company's financial statements.

Credit Risk and the Fair Value of Financial Assets and Financial Liabilities

Effective January 1, 2009, the Company adopted the accounting provisions of Emerging Issues Committee (EIC) Abstract EIC 173, "Credit Risk and the Fair Value of Financial
Assets and Financial Liabilities". Under EIC 173 an entity's own credit risk and the credit risk of its counterparties are taken into account in determining the fair value of financial assets
and financial liabilities, including derivative instruments. Adopting this accounting change did not have a material effect on the Company's financial statements.

Future Accounting Changes

Business Combinations, Consolidated Financial Statements and Non-Controlling Interests

The CICA Handbook Section 1582 "Business Combinations" is effective for business combinations with an acquisition date after January 1, 2011. This standard was
amended to require additional use of fair value measurements, recognition of additional assets and liabilities, and increased disclosure. Adopting the standard is expected to have a material effect on
the way the Company accounts for future business combinations. Entities adopting Section 1582 will also be required to adopt CICA Handbook Sections 1601 "Consolidated Financial
Statements" and 1602 "Non-Controlling Interests". These standards will require non-controlling interests to be presented as part of Shareholders' Equity on the balance sheet.
In addition, the income statement of the controlling parent will include 100 per cent of the subsidiary's results and present the allocation between the controlling and
non-controlling interests. These standards will be effective January 1, 2011, with early adoption permitted. The changes resulting from adopting Section 1582 will be applied
prospectively and the changes from adopting Sections 1601 and 1602 will be applied retrospectively.

International Financial Reporting Standards

The CICA's Accounting Standards Board announced that Canadian publicly accountable enterprises are required to adopt International Financial Reporting Standards (IFRS), as
issued by the International Accounting Standards Board (IASB), effective January 1, 2011. Effective January 1, 2011, the Company will begin reporting under IFRS.

TransCanada
currently follows specific accounting policies unique to a rate-regulated business. TransCanada has established a project team to support adopting
IFRS. The project team is actively monitoring developments regarding potential future guidance on the applicability of certain aspects of rate-regulated accounting under IFRS. Developments
in this area could have a significant effect on the scope of the Company's IFRS project and on TransCanada's financial results under IFRS. On July 23,
2009, the IASB issued an exposure draft "Rate-regulated Activities". The Company is assessing the impact of developments related to the exposure draft.

As
a result of proposed changes to certain IFRS, together with the current stage of the Company's IFRS project, TransCanada cannot reasonably quantify the full impact that
adopting IFRS will have on its financial position and future results.

NOTE 4    SEGMENTED INFORMATION

Effective January 1, 2009, TransCanada revised its presentation of certain income and expense items in the Consolidated Statement of Income to better reflect the
operating and financing structure of the Company. To conform with the new presentation, certain of the income and expense amounts pertaining to operations that were previously classified on the
Consolidated Income Statement as Other Expenses/(Income) are now included in Operating and Other Expenses/(Income). Depreciation expense has been redefined as Depreciation and Amortization expense and
includes amortization of $58 million in 2009 (2008 and 2007  $58 million), for PPAs, which was previously included in Commodity Purchases Resold.
Support services costs previously allocated to Pipelines and Energy of $112 million in 2009 (2008  $106 million;
2007  $97 million) are now included in Corporate. In addition, amounts related to Interest Expense and Interest Expense of Joint Ventures, Interest Income
and Other, Income Taxes and Non-Controlling Interests are no longer reported on a segmented basis. Segmented information has been retroactively reclassified to reflect these changes. These
changes had no impact on reported consolidated Net Income.

NOTE 9    ACQUISITIONS AND DISPOSITIONS

Pipelines

Keystone

In August 2009, TransCanada purchased ConocoPhillips' remaining ownership interest in Keystone of approximately 20 per cent for US$553 million plus
the assumption of US$197 million of short-term debt. The acquisition increased TransCanada's ownership interest in Keystone to 100 per cent and was recorded in Plant,
Property and Equipment. The purchase price reflected ConocoPhillips' capital contributions to date and included capitalization of interest during construction. TransCanada began fully consolidating
Keystone into its Pipelines segment upon acquisition.

In
2008, TransCanada entered into an agreement with ConocoPhillips to increase its equity ownership in Keystone to approximately 80 per cent from
50 per cent, with ConocoPhillips' equity ownership in Keystone being reduced concurrently to approximately 20 per cent from 50 per cent. In 2008 and prior to
August 2009, TransCanada funded 100 per cent of the construction expenditures until the participants' project capital contributions were aligned with their revised ownership interests.
In 2009, prior to August, TransCanada funded $1.3 billion of cash calls for Keystone, resulting in the Company acquiring an incremental increase in ownership of approximately
18 per cent for $313 million. In 2008, the Company funded $362 million of cash calls, resulting in an incremental increase in ownership of approximately
12 per cent for $176 million. TransCanada's ownership interest was approximately 80 per cent and 62 per cent in August 2009 and
December 31, 2008, respectively. TransCanada proportionately consolidated the Keystone partnerships prior to August 2009.

During
2008, Keystone purchased pipeline facilities located in Saskatchewan and Manitoba from the Canadian Mainline for use in the construction of the Keystone oil pipeline.
The sale was completed in three phases for total proceeds of $67 million, with no gain recognized on the sale.

ANR and Great Lakes

On February 22, 2007, TransCanada acquired from El Paso Corporation 100 per cent of ANR and an additional 3.6 per cent interest in Great Lakes
for a total of US$3.4 billion, including US$491 million of assumed long-term debt. The acquisitions were accounted for using the purchase method of accounting. TransCanada
began consolidating ANR and Great Lakes into the Pipelines segment upon acquisition. The purchase price was allocated as follows:

TC PipeLines, LP Acquisition of Interest in Great Lakes

On February 22, 2007, PipeLines LP acquired from El Paso Corporation a 46.4 per cent interest in Great Lakes for US$942 million, including
US$209 million of assumed long-term debt. The acquisition was accounted for using the purchase method of accounting. TransCanada began consolidating Great Lakes into its Pipelines
segment after the acquisition date.

|                              |  |      |   | 

The
allocation of the purchase price for these transactions was made using the fair value of the net assets at the date of acquisition. Tolls charged by ANR and Great Lakes
are subject to rate regulation based on historical costs. As a result, the regulated net assets, other than ANR's gas held for sale, were determined to have a fair value equal to their
rate-regulated value.

Factors
that contributed to goodwill included the opportunity to expand further in the U.S. market and to gain a stronger competitive position in the North American
gas transmission business. Goodwill related to TransCanada's ANR and Great Lakes transactions is not amortizable for tax purposes. Goodwill related to PipeLines LP's Great Lakes transaction is
amortizable for tax purposes.

TC PipeLines, LP

On November 18, 2009, PipeLines LP completed an offering of five million common units at a price of US$38.00 per unit. The issue resulted in net proceeds to
PipeLines LP of US$182 million. TransCanada contributed an additional US$3.8 million to maintain its general partnership interest but did not purchase any other units. Upon
completion of the offering, the Company's ownership interest in PipeLines LP decreased to 38.2 per cent and the Company recognized a dilution gain of $18 million after tax
($29 million pre-tax).

On
July 1, 2009, TransCanada sold North Baja to PipeLines LP. As part of the transaction, TransCanada agreed to amend its general partner incentive
distribution rights arrangement with PipeLines LP. TransCanada received aggregate consideration totalling approximately US$395 million from PipeLines LP, including
US$200 million in cash and 6,371,680 common units of PipeLines LP. TransCanada recorded no gain or loss as a result of the transaction. TransCanada's ownership in
PipeLines LP increased to 42.6 per cent as a result of the transaction. TransCanada's increased ownership in PipeLines LP also resulted in a decrease in
Non-Controlling Interests and an increase in Contributed Surplus.

In
February 2007, PipeLines LP completed a private placement offering of 17.4 million common units at a price of US$34.57 per unit. TransCanada acquired
50 per cent of the units for US$300 million. TransCanada also invested an additional US$12 million to maintain its general partnership interest in PipeLines LP. As a
result of these additional investments, TransCanada's ownership in PipeLines LP was 32.1 per cent on February 22, 2007. The total private placement, together with
TransCanada's additional investment, resulted in gross proceeds to PipeLines LP of US$612 million, which were used to partially finance its acquisition of the 46.4 per cent
ownership interest in Great Lakes.

The
allocation of the purchase price was made using the fair value of the net assets at the date of acquisition. Factors that contributed to goodwill included the
opportunity to expand the Energy segment further into the U.S. market and to gain a stronger competitive position in the North American power generation business. The goodwill recognized on the
transaction is amortizable for tax purposes.

Ontario Land Sale

In November 2007, TransCanada's Energy segment sold land in Ontario that had previously been held for development, generating net proceeds of $37 million and
recognizing an after tax gain of $14 million on the sale.

The
long-term debt of joint ventures is non-recourse to TransCanada, except that TransCanada has provided certain pro-rata guarantees
related to the capital lease obligations of Bruce Power. The security provided with respect to the debt of each joint venture is limited to the rights and assets of the joint venture and does not
extend to the rights and assets of TransCanada, except to the extent of TransCanada's investment. Trans Québec & Maritimes Pipeline Inc.'s (TQM Pipeline) bonds are secured
by a first interest in all TQM Pipeline real and immoveable property and rights, a floating charge on all residual property and assets, and a specific interest on bonds of TQM
Finance Inc. and on rights under all licenses and permits relating to the TQM pipeline system and natural gas transportation agreements.

Subject
to meeting certain requirements, the Bruce Power capital lease agreements provide for a series of renewals commencing January 1, 2019. The first renewal is
for a period of one year and each of 12 renewals thereafter is for a period of two years.

The
Company's proportionate share of principal repayments for the next five years resulting from maturities and sinking fund obligations of the non-recourse
joint venture debt is approximately as follows: 2010  $199 million; 2011  $21 million;
2012  $120 million; 2013  $7 million; and 2014  $44 million.

The
Company's proportionate share of principal payments for the next five years resulting from the capital lease obligations of Bruce Power is approximately as follows:
2010  $13 million; 2011  $15 million; 2012  $18 million;
2013  $20 million; and 2014  $23 million.

In
September 2009, TQM issued $75 million of bonds maturing in September 2014 and bearing interest at 4.05 per cent.

In
August 2009, Northern Border issued US$100 million of Senior Unsecured Notes maturing in August 2016 and bearing interest at
6.24 per cent.

In
May 2009, Iroquois issued US$140 million Senior Unsecured Notes maturing in May 2019 and bearing interest at 6.63 per cent.

In
September 2008, Bruce A entered into a $193 million unsecured term loan maturing December 2031 and bearing interest at 7.1 per cent.

Sensitivity

A one per cent change in interest rates would have the following effect on net income assuming all other variables were to remain constant:

NOTE 14    RATE REGULATED BUSINESSES

TransCanada's rate regulated businesses currently include Canadian and U.S. natural gas pipelines and regulated U.S. natural gas storage. Regulatory assets and
liabilities represent future revenues that are expected to be recovered from or refunded to customers based on decisions and approvals by the applicable regulatory authorities. In addition to GAAP
financial reporting, TransCanada's regulated pipelines file financial reports using accounting regulations required by their respective regulators.

Canadian Regulated Operations

Canadian natural gas transmission services are supplied under natural gas transportation tariffs that provide for cost recovery, including return of and return on capital as
approved by the applicable regulatory authorities.

Rates
charged by TransCanada's Canadian regulated pipelines are set typically through a process that involves filing an application with the regulators for a change in
rates. Regulated rates are underpinned by the total annual revenue requirement, which comprises a specified annual return on capital, including debt and equity, and all necessary operating expenses,
taxes and depreciation.

TransCanada's
Canadian regulated pipelines have generally been subject to a cost-of-service model wherein forecasted costs, including a return on
capital, determine the revenues for the upcoming year. To the extent that actual costs and revenues are more or less than the forecasted costs and revenues, the regulators generally allow the
difference to be deferred to a future period and recovered or refunded in rates at that time. Costs for which the regulator does not allow the difference between actual and forecast to be deferred are
included in the determination of net income in the year they are incurred.

The
Canadian Mainline, Alberta System, Foothills and TQM pipelines are regulated by the NEB under theNational Energy Board Act(Canada). Following an application by TransCanada to the NEB requesting a change in regulatory jurisdiction for the Alberta System, the NEB determined that the Alberta System is within federal
jurisdiction and subject to NEB regulation effective April 29, 2009. Prior to April 2009, the Alberta

122NOTES TO

System
was regulated by the AUC primarily under the provisions of theGas Utilities Act(Alberta) and thePipeline
Act(Alberta). The NEB regulates the construction and operation of facilities, and the terms and conditions of services, including rates, for the Company's Canadian regulated
natural gas transmission systems.

In
October 2009, the NEB issued a decision that its RH-2-94 Decision, which had established a rate of return on common equity (ROE)
formula that formed the basis of determining tolls for pipelines under NEB jurisdiction since 1995, would not continue to be in effect. A company's cost of capital will now be determined by
negotiations between pipeline companies and their shippers or by the NEB if a pipeline company files a cost of capital application. This decision impacts TransCanada's NEB regulated pipelines,
however, the Canadian Mainline will continue to base its return on the RH-2-94 NEB ROE formula for the years 2010 and 2011 in accordance with the terms of the current
Canadian Mainline tolls settlement. In November 2009, certain industry stakeholders appealed the October 2009 NEB decision with the Federal Court of Appeal and named the NEB as the sole
respondent. TransCanada was granted respondent status in the matter and filed its submission opposing the leave application in February 2010.

Canadian Mainline

The Canadian Mainline currently operates under a five-year tolls settlement, which is effective January 1, 2007, to December 31, 2011. Canadian
Mainline's cost of capital for establishing tolls under the settlement reflects ROE as determined by the NEB's ROE formula, on a deemed common equity ratio of 40 per cent. The allowed
ROE in 2009 for the Canadian Mainline was 8.57 per cent (2008  8.71 per cent). The balance of the capital structure is comprised of
short- and long-term debt.

The
settlement also establishes the Canadian Mainline's fixed operating, maintenance and administrative (OM&A) costs for each year of the five years. Any variance between
actual OM&A costs and those agreed to in the settlement have accrued fully to TransCanada from 2007 to 2009. Variances in OM&A costs will be shared equally between TransCanada and its customers in
2010 and 2011. All other cost elements of the revenue requirement are treated on a flow-through basis. There are also performance-based incentive arrangements that provide mutual benefits
to both TransCanada and its customers.

Alberta System

In 2008 and 2009, the Alberta System operated under a two-year revenue requirement settlement approved by the AUC in 2008 and the NEB in 2009. As part of the
settlement, fixed costs were established for ROE, income taxes and certain OM&A costs. Any variances between actual costs and those agreed to in the settlement accrue to TransCanada, subject to ROE
and income tax adjustment mechanisms. All other costs are treated on a flow-through basis.

Foothills

The ROE for Foothills, which is based on the NEB-allowed ROE formula, was 8.57 per cent in 2009
(2008  8.71 per cent) on a deemed equity component of 36 per cent. A component of OM&A costs are fixed, subject to the terms of the
BC System/Foothills Integration Settlement, with variances between actual and the fixed amounts shared with customers.

TQM

In June 2009, the NEB approved TQM's final tolls for 2007 and 2008, consisting of a 6.4 per cent after-tax weighted average cost of capital as
authorized by the NEB in its RH-1-2008 Decision released in March 2009. This decision equates to a 9.85 per cent return on 40 per cent
deemed common equity in 2007 and a 9.75 per cent return on 40 per cent deemed common equity in 2008. The decision granted TQM an aggregate return on capital and did not
specify capital structure. Prior to this decision, TQM was subject to the NEB ROE formula on deemed common equity of 30 per cent. TQM's 2009 tolls remain in effect on an interim basis
pending resolution of its cost of capital.

U.S. Regulated Operations

TransCanada's U.S. natural gas pipelines are 'natural gas companies' operating under the provisions of theNatural Gas Act of
1938,theNatural Gas Policy Act of 1978and theEnergy Policy Act of 2005, and are
subject to the jurisdiction of the FERC. TheNatural Gas Act of
1938grants the FERC authority over the construction and operation of pipelines and related facilities. The FERC also has authority to regulate rates for natural gas
transportation in interstate commerce.

ANR

ANR's operations are regulated primarily by the FERC. ANR's natural gas storage and transportation services regulated by the FERC also operate under approved tariff rates. ANR
Pipeline Company's rates were established pursuant to a settlement approved by a FERC order issued in 1998. These tariffs include maximum and minimum rate levels for services and permit ANR to
discount or negotiate rates on a non-discriminatory basis. ANR Storage Company's rates were established pursuant to a settlement approved by the FERC in 1990. None of ANR's
FERC-regulated operations are currently required to file for new rates at any time in the future, nor are any of the operations prohibited from filing a case for new rates.

GTN

GTN is regulated by the FERC and operates in accordance with FERC-approved tariffs that establish maximum and minimum rates for various services. GTN is permitted to
discount or negotiate these rates on a non-discriminatory basis. In November 2007, GTN and its customers

reached
a rate case settlement that was approved by the FERC in January 2008. The settlement had an effective date of January 1, 2007, and established the rates currently in effect.
Under the settlement, a five-year moratorium was established, during which GTN and the settling parties are prohibited from taking certain actions under theNatural
Gas Act of 1938, including any rate adjustment filings. The settlement requires GTN to file a rate case within seven years of the effective date.

Great Lakes

In November 2009, the FERC initiated an investigation to determine whether Great Lakes' rates are just and reasonable. In response, Great Lakes filed a cost and revenue
study with the FERC on February 4, 2010. A hearing is scheduled to commence on August 2, 2010, and an Initial Decision is required in November 2010. The impact of the
investigation on Great Lakes' rates and revenues is unknown at this time.

Portland

In April 2008, Portland filed a general rate case with the FERC proposing a rate increase of approximately six per cent as well as other changes to its tariff. In
May 2009, Portland reached a settlement with its customers on certain short-term issues in its rate case. The partial settlement has since been filed with the FERC and a final
decision approving this partial settlement is expected in 2010. The remaining issues were litigated and Portland received the Initial Decision from the Administrative Law Judge in
December 2009. Participants in the rate case now have an opportunity to respond to the Initial Decision. The FERC is expected to issue its final decision on the litigated portion of the rate
case in fourth quarter 2010.

Northern Border

Northern Border and its customers reached a settlement in September 2006 that was approved by the FERC in November 2006. The settlement established maximum
long-term mileage-based rates and charges for transportation on Northern Border's system. It provided for seasonal rates, which vary on a monthly basis, for short-term
transportation services. It also included a three year moratorium on filing rate cases and on participants filing challenges to rates, and required Northern Border to file a general rate
case within six years. Northern Border is required to provide services under negotiated and discounted rates on a non-discriminatory basis.

July 2008, TransCanada filed a base shelf prospectus to allow for the offering of up to $3.0 billion of common shares, preferred shares and subscription
receipts in Canada and the U.S. until August 2010. This base shelf prospectus replaced the base shelf prospectus filed in January 2007. The July 2008 prospectus was
depleted by the common share issues discussed below.

In
January 2007, TransCanada filed a base shelf prospectus to allow for the offering of up to $3.0 billion of common shares, preferred shares and subscription
receipts in Canada and the U.S. until February 2009. The January 2007 prospectus was depleted by the common share issues discussed below.

Net Income per Share

Net Income per Share is calculated by dividing Net Income Applicable to Common Shares by the weighted average number of common shares. During the year, the weighted average
number of common shares of 651.8 million and 652.8 million (2008  569.6 million and 571.5 million;
2007  529.9 million and 532.5 million) were used to calculate basic and diluted earnings per share, respectively. The increase in the weighted
average number of shares for the diluted earnings per share calculation is due to the options exercisable under TransCanada's Stock Option Plan.

An
additional 3.2 million common shares were reserved for future issuance under TransCanada's Stock Option Plan at December 31, 2009. The weighted average fair
value of options granted to purchase common shares under the Company's Stock Option Plan was determined to be $4.78 (2008  $3.97;
2007  $4.22). The Company used the Black-Scholes model for determining the fair value of options granted applying the following weighted average assumptions for
2009: four years of expected life
(2008 and 2007  four years); 1.7 per cent interest rate (2008  3.5 per cent;
2007  4.1 per cent); 29 per cent volatility (2008  16 per cent;
2007  15 per cent); and 5.2 per cent dividend yield (2008  4.0 per cent;
2007  3.6 per cent). The amount expensed for stock options, with a corresponding increase in contributed surplus, was $4 million in 2009
(2008 and 2007  $4 million).

The
total intrinsic value of options exercised in 2009 was $15 million (2008  $15 million;
2007  $21 million). As at December 31, 2009, the aggregate intrinsic value for the total currently exercisable options was $47 million and
the total intrinsic value of outstanding options was $52 million. In 2009, the 1.2 million (2008  1.4 million;
2007  1.4 million) shares that vested had a fair value of $43 million (2008  $45 million;
2007  $57 million).

Shareholder Rights Plan

TransCanada's Shareholder Rights Plan is designed to encourage the fair treatment of shareholders in connection with any takeover offer for the Company. Under certain
circumstances, each common share is entitled to one right that entitles certain holders to purchase two common shares of the Company for the price of one.

Cash Dividends

Cash dividends of $722 million or $1.50 per common share were paid in 2009 (2008  $577 million or $1.42 per common share;
2007  $546 million or $1.34 per common share).

Dividend Reinvestment and Share Purchase Plan

TransCanada's Board of Directors authorized the issuance of common shares from treasury at a discount to participants in the Company's Dividend Reinvestment and Share Purchase
Plan (DRP). Under the DRP, eligible holders of common and preferred shares of TransCanada and preferred shares of TCPL may reinvest their dividends and make optional cash payments to obtain
TransCanada common shares. The DRP shares are provided to the participants at a discount to the average market price in the five days prior to dividend payment. The discount was set at two
per cent commencing with the dividend payable in April 2007 and was increased to three per cent with the dividend payable in January 2009. Prior to the April 2007
dividend, TransCanada purchased shares on the open market and provided them to DRP participants at cost. The Company reserves the right to alter the discount or return to purchasing shares on the open
market at any time. In 2009, dividends of $254 million were paid (2008  $218 million;
2007  $157 million) through the issuance of 8.2 million (2008  6.0 million;
2007  4.1 million) common shares from treasury in accordance with the DRP.

In
September 2009, TransCanada completed a public offering of 22 million cumulative redeemable first preferred shares under a prospectus supplement to the
September 2009 base shelf prospectus for gross proceeds of $550 million. The holders of the preferred shares are entitled to receive fixed cumulative dividends at an annual rate of $1.15
per share, payable quarterly, yielding 4.6 per cent per annum, for the initial five year period ending December 31, 2014. The dividend rate will reset on December 31, 2014
and every five years thereafter to a yield per annum equal to the sum of the then five year Government of Canada bond yield plus 1.92 per cent. The preferred shares are redeemable by
TransCanada on or after December 31, 2014 at a price of $25 per share plus all accrued and unpaid dividends. The preferred shareholders are eligible to participate in the Company's DRP. The
first dividend was paid December 31, 2009.

The
preferred shareholders will have the right to convert their shares into Series 2 cumulative redeemable first preferred shares on December 31, 2014 and on
December 31 of every fifth year thereafter. The holders of Series 2 preferred shares will be entitled to receive quarterly floating rate cumulative dividends at a yield per annum equal
to the sum of the then 90-day Government of Canada treasury bill rate and 1.92 per cent.

Cash Dividends

Cash dividends of $6 million or $0.2875 per preferred share were paid in 2009.

NOTE 18    RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

Risk Management Overview

TransCanada has exposure to market risk, counterparty credit risk and liquidity risk. TransCanada engages in risk management activities with the objective being to protect
earnings, cash flow and, ultimately, shareholder value.

Risk
management strategies, policies and limits are designed to ensure TransCanada's risks and related exposures are in line with the Company's business objectives and risk
tolerance. Risks are managed within limits ultimately established by the Company's Board of Directors, implemented by senior management and monitored by risk management and internal audit personnel.
The Board of Directors' Audit Committee oversees how management monitors compliance with risk management policies and procedures, and oversees management's review of the adequacy of the risk
management framework. Internal audit personnel assist the Audit Committee in its oversight role by performing regular and ad-hoc reviews of risk management controls and procedures, the
results of which are reported to the Audit Committee.

Market Risk

The Company constructs and invests in large infrastructure projects, purchases and sells energy commodities, issues short-term and long-term debt,
including amounts in foreign currencies, and invests in foreign operations. These activities expose the Company to market risk from changes in commodity prices, foreign exchange rates and interest
rates, which affect the Company's earnings and the value of the financial instruments it holds.

The
Company uses derivatives as part of its overall risk management strategy to manage the exposure to market risk that results from these activities. Derivative contracts
used to manage market risk generally consist of the following:

Commodity Price Risk

The Company is exposed to commodity price movements as part of its normal business operations, particularly in relation to the prices of electricity, natural gas and oil
products. A number of strategies are used to mitigate these exposures, including the following:

The
Company assesses its commodity contracts and derivative instruments used to manage commodity risk to determine the appropriate accounting treatment. Contracts, with the
exception of leases, have been assessed to determine whether they or certain aspects of them meet the definition of a derivative. Certain commodity purchase and sale contracts are derivatives but are
not within the scope of the CICA Handbook Section 3855 "Financial Instruments  Recognition and Measurement", as they were entered into and continue to be
held for the purpose of receipt or delivery in accordance with the Company's expected purchase, sale or usage requirements. Certain other contracts are not within the scope of Section 3855 as
they are considered to meet other exemptions.

TransCanada
manages its exposure to seasonal natural gas price spreads in its natural gas storage business by economically hedging storage capacity with a portfolio of
third-party storage capacity contracts and proprietary natural gas purchases and sales. TransCanada simultaneously enters into a forward purchase of natural gas for injection into storage and an
offsetting forward sale of natural gas for withdrawal at a later period, thereby locking in future positive margins and effectively eliminating exposure to natural gas price movements. Fair value
adjustments recorded each period on proprietary natural gas inventory in storage and these forward contracts may not be representative of the amounts that will be realized on settlement.

STATEMENTS131

Natural Gas Inventory Price Risk

At December 31, 2009, the fair value of proprietary natural gas inventory in storage, as measured using a weighted average of forward prices for the following four months
less selling costs, was $73 million (2008  $76 million). The change in fair value of proprietary natural gas inventory in storage in 2009 resulted
in a net pre-tax unrealized gain of $3 million (2008  unrealized loss of $7 million; 2007  nil),
which was recorded as an increase to Revenues and Inventories. The net change in fair value of natural gas forward purchase and sales contracts in 2009 resulted in a net pre-tax unrealized
loss of $2 million (2008  unrealized gain of $7 million; 2007 unrealized gain of $10 million), which was recorded as a decrease
in Revenues.

Foreign Exchange and Interest Rate Risk

Foreign exchange and interest rate risk is created by fluctuations in the fair value or cash flow of financial instruments due to changes in foreign exchange rates and market
interest rates.

A
portion of TransCanada's earnings from its Pipelines and Energy segments is generated in U.S. dollars and, as such, movement of the Canadian dollar relative to the
U.S. dollar can affect TransCanada's earnings. This foreign exchange impact is offset by certain related debt and financing costs being denominated in U.S. dollars and by the Company's hedging
activities. TransCanada has a greater
exposure to U.S. currency fluctuations than in prior years due to growth in its U.S. operations, partially offset by increased levels of U.S. dollar-denominated debt.

The
Company uses foreign currency and interest rate derivatives to manage the foreign exchange and interest rate risks related to its debt and other
U.S. dollar-denominated transactions, and to manage the interest rate exposures of the Canadian Mainline, Alberta System and Foothills operations. Certain of the realized gains and losses on
these derivatives are shared with shippers on predetermined terms. These gains and losses are deferred as regulatory assets and liabilities until they are recovered from or paid to the shippers in
accordance with the terms of the shipping agreements.

TransCanada
has floating interest rate debt, which subjects it to interest rate cash flow risk. The Company uses a combination of interest rate swaps and options to manage
its exposure to this risk.

On
a consolidated basis, the impact of changes in the U.S. dollar on U.S. Pipelines and Energy earnings is largely offset by the impact on U.S. dollar
interest expense. The resultant net exposure is managed using derivatives, effectively reducing the Company's exposure to changes in foreign exchange rates.

Net Investment in Self-Sustaining Foreign Operations

The Company hedges its net investment in self-sustaining foreign operations (on an after-tax basis) with U.S. dollar-denominated debt,
cross-currency interest rate swaps, forward foreign exchange contracts and foreign exchange options. At December 31, 2009, the Company had designated as a net investment hedge
U.S. dollar-denominated debt with a carrying value of $7.9 billion (US$7.6 billion) (2008  $7.2 billion (US$5.9 billion)) and
a fair value of $9.8 billion (US$9.3 billion) (2008  $5.9 billion (US$4.8 billion)). At December 31, 2009, $96 million
was included in Intangibles and Other Assets (2008  $254 million in Deferred Amounts) for the fair value of the forwards, swaps and options used to hedge
the Company's net U.S. dollar investment in foreign operations.

The
fair values and notional or principal amounts for the derivatives designated as a net investment hedge were as follows:

VaR Analysis

TransCanada uses a Value-at-Risk (VaR) methodology to estimate the potential impact resulting from its exposure to market risk on its open liquid
positions. VaR estimates the potential change in pre-tax earnings over a given holding period for a specified confidence level. The VaR number calculated and used by TransCanada reflects a
95 per cent probability that the daily change resulting from normal market fluctuations in its open liquid positions will not exceed the reported VaR. The VaR methodology is a
statistically-calculated, probability-based approach that takes into consideration market volatilities as well as risk diversification by recognizing offsetting positions and correlations among
products and markets. Risks are measured across all products and markets, and risk measures are aggregated to arrive at a single VaR number.

There
is currently no uniform industry methodology for estimating VaR. The use of VaR has limitations because it is based on historical correlations and volatilities in
commodity prices, interest rates and foreign exchange rates, and assumes that future price movements will follow a statistical distribution. Although losses are not expected to exceed the
statistically estimated VaR on 95 per cent of occasions, losses on the other five per cent of occasions could be substantially greater than the estimated VaR.

TransCanada's
estimation of VaR includes wholly owned subsidiaries and incorporates relevant risks associated with each market or business unit. The calculation does not
include the Pipelines segment as the rate-regulated nature of the pipeline business reduces the impact of market risks. TransCanada's Board of Directors has established a VaR limit, which
is monitored on an ongoing basis as part of the Company's risk management policy. TransCanada's consolidated VaR was $12 million at December 31, 2009
(2008  $23 million). The decline from December 31, 2008 was primarily due to decreased prices and lower open positions in the U.S. power
portfolio.

Counterparty Credit Risk

Counterparty credit risk represents the financial loss the Company would experience if a counterparty to a financial instrument failed to meet its obligations in accordance with
the terms and conditions of its contracts with the Company.

Counterparty
credit risk is managed through established credit management techniques, including conducting financial and other assessments to establish and monitor a
counterparty's creditworthiness, setting exposure limits, monitoring exposures against these limits, using master netting arrangements and obtaining financial assurances where warranted. In general,
financial assurances include guarantees, letters of credit and cash. The Company monitors and manages its concentration of counterparty credit risk on an ongoing basis. The Company believes these
measures minimize its counterparty credit risk but there is no certainty that they will protect it against all material losses.

TransCanada's
maximum counterparty credit exposure with respect to financial instruments at the balance sheet date consisted primarily of non-derivative
financial assets such as accounts receivable, loans and notes receivable, as well as the fair value of derivative assets. Within these balances, the Company does not have significant concentrations of
counterparty credit risk with any individual counterparties and the majority of counterparty credit exposure is with counterparties who are investment grade. At December 31, 2009, there were no
significant amounts past due or impaired.

TransCanada
has significant credit and performance exposures to financial institutions as they provide committed credit lines and cash deposit facilities, critical liquidity
in the foreign exchange derivative, interest rate derivative and energy wholesale markets, and letters of credit to mitigate TransCanada's exposure to non-creditworthy counterparties.

As
a level of uncertainty continues to exist in the global financial markets, TransCanada continues to closely monitor and reassess the creditworthiness of its
counterparties. This has resulted in TransCanada reducing or mitigating its exposure to certain counterparties where it was deemed warranted and permitted under contractual terms. As part of its
ongoing operations, TransCanada must balance its market and counterparty credit risks when making business decisions.

Certain
subsidiaries of Calpine Corporation (Calpine) filed for bankruptcy protection in both Canada and the U.S. in 2005. Gas Transmission Northwest Corporation
(GTNC) and Portland reached agreements with Calpine for allowed unsecured claims in the Calpine bankruptcy. In February 2008, GTNC and Portland received initial distributions of
9.4 million common shares and 6.1 million common shares, respectively, of Calpine, which represented approximately 85 per cent of their agreed-upon claims. In
2008, these shares were sold into the open market and resulted in total pre-tax gains of $279 million. Claims by NGTL and Foothills Pipe Lines (South B.C.) Ltd. for
$32 million and $44 million, respectively, were received in cash in January 2008 and were passed on to shippers on these systems in 2008 and 2009.

Liquidity Risk

Liquidity risk is the risk that TransCanada will not be able to meet its financial obligations when due. The Company's approach to managing liquidity risk is to ensure that,
under both normal and stressed conditions, it always has sufficient cash and credit facilities to meet its obligations when due without incurring unacceptable losses or damage to the Company's
reputation.

Management
continuously forecasts cash flows for a period of 12 months to identify financing requirements. These requirements are then managed through a combination
of committed and demand credit facilities and access to capital markets, as discussed under the heading Capital Management below.

At
December 31, 2009, the Company had committed revolving bank lines of US$1.0 billion, $2.0 billion, US$1.0 billion and US$300 million
maturing November 2010, December 2012, December 2012 and February 2013, respectively. At December 31, 2009, the US$300 million facility was fully drawn and no
draws were made on any of the other facilities. The Company has maintained continuous access to the Canadian commercial paper market on competitive terms.

The
Company has access to capital markets under the following prospectuses:

Capital Management

The primary objective of capital management is to ensure TransCanada has strong credit ratings to support its businesses and maximize shareholder value. In 2009, the overall
objective and policy for managing capital remained unchanged from the prior year.

TransCanada
manages its capital structure in a manner consistent with the risk characteristics of the underlying assets. The Company's management considers its capital
structure to consist of net debt, Non-Controlling Interests and Shareholders' Equity. Net debt is comprised of Notes Payable, Long-Term Debt and Junior Subordinated Notes less
Cash and Cash Equivalents. Net debt only includes obligations that the Company controls and manages. Consequently, it does not include Cash and Cash Equivalents, Notes Payable and
Long-Term Debt of TransCanada's joint ventures.

The
capital structure was as follows:

|December 31 (millions of dollars) |  | 2009   |   | 2008   |   |

|                                 

Fair Values

Certain financial instruments included in Cash and Cash Equivalents, Accounts Receivable, Intangibles and Other Assets, Notes Payable, Accounts Payable, Accrued Interest and
Deferred Amounts have carrying amounts that approximate their fair value due to the nature of the item or the short time to maturity. The fair value of foreign exchange and interest rate derivatives
has been calculated using year-end market rates. The fair value of power, natural gas and oil products derivatives has been calculated using quoted market prices where available. In the
absence of quoted market prices, third-party broker quotes or other valuation techniques are used. Credit risk has been taken into consideration when calculating the fair value of derivatives.

The
fair value of the Company's Long-Term Debt was estimated based on quoted market prices for the same or similar debt instruments and, when such information
was not available, was estimated by discounting future payments of interest and principal at estimated interest rates that were made available to the Company.

Derivative Financial Instruments of Joint Ventures

Included in the Balance Sheet Presentation of Derivative Financial Instruments summary are amounts related to power derivatives used by one of the Company's joint ventures to
manage commodity price risk. The Company's proportionate share of the fair value of these power sales derivatives was $105 million at December 31, 2009
(2008  $75 million). These contracts mature from 2010 to 2015. The Company's proportionate share of the notional sales volumes of power associated with
this exposure was 6,312 gigawatt hours (GWh) at December 31, 2009 (2008  7,600 GWh). The Company's proportionate share of the notional
purchased volumes of power associated with this exposure was 2,747 GWh at December 31, 2009 (2008  47 GWh).

Fair Value Hierarchy

The Company's financial assets and liabilities recorded at fair value have been categorized into three categories based upon a fair value hierarchy. Fair value of assets and
liabilities included in Level I is determined by reference to quoted prices in active markets for identical assets and liabilities. Assets and liabilities in Level II include valuations
using inputs other than quoted prices for which all significant outputs are observable, either directly or indirectly. This category includes fair value determined using valuation techniques, such as
option pricing models and extrapolation using observable inputs. Level III valuations are based on inputs that are not readily observable and are significant to the overall fair value
measurement. Long-dated commodity transactions in certain markets and the fair value of guarantees are included in this category. Long-dated commodity prices are derived with a
third party modelling tool that uses market fundamentals to derive long-term prices. The fair value of guarantees is estimated by discounting the cash flows that would be incurred if
letters of credit were used in place of the guarantees.

Assets
and liabilities measured at fair value as of December 31, 2009, including both current and non-current portions, are categorized as follows. There
were no transfers between Level I and Level II in 2009.

increase or 100 basis points decrease in the discount rate on the fair value of guarantee liabilities outstanding as at December 31, 2009 would cause a $2 million decrease in the

Unremitted Earnings of Foreign Investments

Income taxes have not been provided on the unremitted earnings of foreign investments that the Company does not intend to repatriate in the foreseeable future. Future income tax
liabilities would have increased by approximately $101 million at December 31, 2009 (2008  $102 million) if there had been a provision for
these taxes.

Income Tax Payments

Income tax payments of $83 million, net of refunds received were made in 2009 (2008  $491 million;
2007  $442 million).

In
June 2008, TransCanada executed an agreement with a syndicate of banks for a US$1.5 billion committed, unsecured, one year bridge loan facility,
which was extendible at the option of the Company for an additional six month term. In August 2008, the Company used US$255 million from this facility to fund a portion of the
Ravenswood acquisition and cancelled the remainder of the commitment. In February 2009, the US$255 million was repaid and the facility was cancelled.

NOTE 22    EMPLOYEE FUTURE BENEFITS

The Company sponsors DB Plans that cover the significant majority of employees. Pension benefits provided under the DB Plans are based on years of service and highest average
earnings over three consecutive years of employment, and increase annually in the Canadian pension plan by a portion of the increase in the Consumer Price Index (CPI). Past service costs are amortized
over the expected average remaining service life of employees, which is approximately eight years.

The
Company also provides its employees with a Savings Plan in Canada, 401(k) Plans (DC Plans) in the U.S. and post-employment benefits other than
pensions, including termination benefits and defined life insurance and medical benefits beyond those provided by government-sponsored plans. Past service costs are amortized over the expected average
remaining life expectancy
of former employees, which was approximately 13 years at December 31, 2009. Contributions to the Savings Plan and DC Plans are expensed as incurred. The Company expensed
$21 million in 2009 (2008  $21 million; 2007  $8 million) for the Savings Plan and DC Plans.

Total
cash payments for employee future benefits, consisting of cash contributed by the Company to the DB Plans and other benefit plans, was $168 million in 2009
(2008  $90 million; 2007  $61 million), including $21 million in 2009
(2008  $21 million; 2007  $8 million) related to the Savings Plan and DC Plans.

The
Company measures its accrued benefit obligations and the fair value of plan assets for accounting purposes as at December 31 of each year. The most recent
actuarial valuation of the pension plans for funding purposes was as at January 1, 2010, and the next required valuation will be as at January 1, 2011.

The
overall expected long-term rate of return on plan assets is based on historical and projected rates of return for the portfolio in aggregate and for each
asset class in the portfolio. Assumed projected rates of return are selected after analyzing historical experience and estimating future levels and volatility of returns. Asset class benchmark
returns, asset mix and anticipated benefit payments from plan assets are also considered in determining the overall expected rate of return. The discount rate is based on market interest rates of high
quality bonds that match the timing and benefits expected to be paid under each plan.

A
nine per cent annual rate of increase in the per capita cost of covered health care benefits was assumed for 2010 measurement purposes. The rate was assumed to
decrease gradually to five per cent by 2019 and remain at this level thereafter. A one percentage point change in assumed health care cost trend rates would have the following effects:

Debt
securities included the Company's debt of $4 million (0.3 per cent of total plan assets) and $3 million (0.3 per cent of total
plan assets) at December 31, 2009 and 2008, respectively. Equity securities included the Company's common shares of $8 million (0.6 per cent of total plan assets) and
$4 million (0.3 per cent of total plan assets) at December 31, 2009 and 2008, respectively.

The
assets of the pension plans are managed on a going concern basis subject to legislative restrictions. The plans' investment policies are to maximize returns within an
acceptable risk tolerance. Pension assets are invested in a diversified manner with consideration given to the demographics of the plans' participants.

Employee Future Benefits of Joint Ventures

Certain of the Company's joint ventures sponsor DB Plans as well as post-employment benefits other than pensions, including defined life insurance and medical
benefits beyond those provided by government-sponsored plans. The obligations of these plans are non-recourse to TransCanada. The following amounts in this note, including those in the
accompanying tables, represent TransCanada's proportionate share with respect to these plans.

Total
cash payments for employee future benefits, consisting of cash contributed by the Company's joint ventures to DB Plans and other benefit plans was $54 million
in 2009 (2008  $42 million; 2007  $34 million).

The
Company's joint ventures measure the benefit obligations and the fair value of plan assets for accounting purposes as at December 31 of each year. The most recent
actuarial valuations of the pension plans for funding purposes were as at January 1, 2010, and the next required valuations will be as at January 1, 2011.

operating lease agreements for premises, services and equipment expire at various dates through 2052, with an option to renew certain lease agreements for periods of one
year to ten years. Net rental expense on operating leases in 2009 was $91 million (2008  $52 million;
2007  $34 million).

TransCanada's
commitments under the Alberta PPAs are considered to be operating leases and a portion of these PPAs have been subleased to third parties under similar terms
and conditions. Future payments under these PPAs have been excluded from the above table, as these

are dependent upon plant availability, among other factors. TransCanada's share of power purchased under the PPAs in 2009 was $384 million
(2008  $398 million; 2007  $391 million). The generating capacities and expiry dates of the PPAs are
as follows:

TransCanada
and its affiliates have long-term natural gas transportation and natural gas purchase arrangements as well as other purchase obligations, all of
which are transacted at market prices and in the normal course of business.

Bruce Power

Bruce A has signed commitments with third-party suppliers related to refurbishing and restarting Units 1 and 2. TransCanada's share of these signed commitments, which extend
over a two year period ending December 31, 2011, are as follows:

Loan  Aboriginal Pipeline Group

In 2003, the Mackenzie Delta gas producers, the Aboriginal Pipeline Group (APG) and TransCanada reached an agreement governing TransCanada's role in the Mackenzie Gas Pipeline
(MGP) project. The project would result in a natural gas pipeline being constructed from Inuvik, Northwest Territories, to the northern border of Alberta, where it would connect with the Alberta
System. Under the agreement, TransCanada agreed to finance the APG for its one-third share of project pre-development costs. These costs, on a cumulative basis, are currently
forecast to be between $150 million and $200 million. As at December 31, 2009, the Company had advanced $143 million to the APG.

TransCanada
and the other co-venture companies involved in the MGP continue to pursue approval of the proposed project, focusing on obtaining regulatory approval
and the Canadian government's support of an acceptable fiscal framework. The regulatory process reached a milestone in late December 2009 with the release of the Joint Review Panel's report on
environmental and socio-economic factors relating to the project. That report has been submitted into the NEB review process for approval of the project, which is scheduled to conclude in
April 2010 with final arguments. A decision is currently expected by fourth quarter 2010.

In
the event the co-venture group is unable to reach an agreement with the government on an acceptable fiscal framework, the parties will need to determine the appropriate
next steps for the project. For TransCanada, this may result in a reassessment of the carrying amount of the APG advances.

Other Commitments

At December 31, 2009, TransCanada was committed to Pipelines capital expenditures totalling approximately $2.0 billion related primarily to construction costs of
Keystone, expansion of the Alberta System and construction costs for Guadalajara and Bison.

At
December 31, 2009, the Company was committed to Energy capital expenditures totalling approximately $1.3 billion related primarily to its share of the
construction and development costs of Oakville, Bruce Power, Coolidge, Halton Hills and the second phase of Kibby Wind.

Contingencies

TransCanada is subject to laws and regulations governing environmental quality and pollution control. At December 31, 2009, the Company accrued approximately
$67 million related to operating facilities. The accrued amount represents the Company's estimate of the amount it expects to expend to remediate the sites. However, additional liabilities may
be incurred as assessments occur and remediation efforts continue.

TransCanada
and its subsidiaries are subject to various legal proceedings and actions arising in the normal course of business. While the final outcome of such legal
proceedings and actions cannot be predicted with certainty, it is the opinion of management that the resolution of such proceedings and actions will not have a material impact on the Company's
consolidated financial position or results of operations.

Guarantees

TransCanada, Cameco Corporation and BPC Generation Infrastructure Trust (BPC) have severally guaranteed one-third of certain contingent financial obligations of
Bruce B related to power sales agreements, a lease agreement and contractor services. The guarantees have terms ranging from 2018 to perpetuity. In addition, TransCanada and BPC have severally
guaranteed one-half of certain contingent financial obligations related to an agreement with the Ontario Power Authority to refurbish and restart Bruce A power generation units. The
guarantees were provided as part of the reorganization of Bruce Power in 2005 and have terms ending in 2018 and 2019. In its 2009 decision to renew the operating licenses of Bruce Power, the Canadian
Nuclear Safety Commission (CNSC) ordered that it was no longer necessary for the major partners of Bruce Power, including TransCanada, to provide financial assurances to Bruce Power to support its
license obligations. After adjusting for the CNSC guarantees, TransCanada's share of the potential exposure under these Bruce A and Bruce B guarantees was estimated at December 31, 2009 at
$741 million. The fair value of these Bruce Power guarantees is estimated to be $82 million. The Company's exposure under certain of these guarantees is unlimited.

In
addition to the guarantees for Bruce Power, the Company and its partners in certain other jointly owned entities have either (i) jointly and severally,
(ii) jointly or (iii) severally guaranteed the financial performance of these entities related primarily to redelivery of natural gas, PPA payments and the payment of liabilities.
TransCanada's share of the potential exposure under these guarantees was estimated at December 31, 2009 to range from $351 million to a maximum of $632 million. The fair value of
these guarantees is estimated to be $9 million which has been included in Deferred Amounts. The Company's exposure under certain of these guarantees is unlimited. For certain of these entities,
any payments made by TransCanada under these guarantees in excess of its ownership interest are to be reimbursed by its partners.

Hedging Instruments and Activities

The Company adopted the U.S. standards for disclosures regarding derivatives and hedging effective January 1, 2009. This standard is intended to enhance the
current disclosure requirements to provide more information about how derivatives and hedging activities affect an entity's financial position, financial performance and cash flows. Many of these
disclosures are provided in the Company's consolidated financial statements prepared under Canadian GAAP. Additional required information is provided below.

Derivative contracts entered into to manage market risk often contain financial assurances provisions that allow parties to the contracts to manage
credit risk. These provisions may require collateral to be provided if a credit-risk-related contingent event occurs, such as a downgrade in the Company's credit rating to
non-investment grade. Based on contracts in place and market prices at December 31, 2009, the aggregate fair value of all derivative instruments with
credit-risk-related contingent features that are in a net liability position is $122 million, for which the Company has provided collateral of $8 million in the
normal course of business. If the credit-risk-related contingent features in these agreements were triggered on December 31, 2009, the Company may be required to provide
additional collateral of $114 million to its counterparties. Collateral may also need to be provided should the fair value of derivative instruments exceed pre-defined contractual
exposure limit thresholds. The Company has sufficient liquidity in the form of cash and undrawn committed revolving bank lines to meet these contingent obligations should they arise.

Postretirement Benefit Plan Assets

Pension assets are invested in high-quality asset classes designed to maximize returns and diversify risk, with consideration given to the demographics of the plan
members. Asset mix strategies may incorporate equity securities, debt securities, real estate and derivatives that hedge against risk. Derivatives are not used for speculative purposes and the use of
leveraged derivatives is prohibited.

All
investments are measured at fair value using market prices. Where the fair value cannot be readily determined by reference to generally available price quotations, the fair value is determined by
considering the discounted cash flows on a risk-adjusted basis and by comparison to similar assets which are publicly traded.

The
following table presents plan assets for defined benefit plans and other postretirement benefits measured at fair value as at December 31, 2009 categorized as follows:

TransCanada expects the enactment of certain Canadian federal tax legislation in the next twelve months which is expected to result in a favourable income tax
adjustment of approximately $12 million. Otherwise, subject to the results of audit examinations by taxing authorities and other legislative amendments, TransCanada does not anticipate further
adjustments to the unrecognized tax benefits during the next twelve months that would have a material impact on its financial statements.

TransCanada
and its subsidiaries are subject to either Canadian federal and provincial income tax, U.S. federal, state and local income tax or the relevant income tax in other international
jurisdictions. The Company has substantially concluded all Canadian federal and provincial income tax matters for the years through 2005. Substantially all material U.S. federal income tax
matters have been concluded for years through 2005 and U.S. state and local income tax matters through 2003.

TransCanada's
continuing practice is to recognize interest and penalties related to income tax uncertainties in income tax expense. Included in net tax expense for the year ended December 31,
2009 is $8 million of interest income and nil for penalties (December 31, 2008  $10 million for interest and nil for penalties). At
December 31, 2009, the Company had $16 million accrued for interest and nil accrued for penalties (December 31, 2008  $24 million
accrued for interest and nil accrued for penalties).

Changes in Accounting Policies

In January 2010, FASB issued new guidance on "Fair Value Measurements and Disclosures" which requires further disclosures with respect to recurring or nonrecurring fair
value measurements. In particular, transfers in and out of Levels I and II in the fair value hierarchy must be disclosed as well as information about valuation techniques and inputs used
to measure fair value for both Level II and Level III measurements. This guidance is effective for fiscal years ending after December 15, 2009 and the Company adopted these
standards for its 2009 year-end reporting by expanding its fair value disclosure. In addition, activity in Level III including purchases, sales, issuances and settlements
must be disclosed on a gross basis for interim periods beginning after December 15, 2010.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Internal control over financial reporting is a process designed by or under the supervision of senior management of TransCanada Corporation ("TransCanada"), and effected by the
Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and preparation of consolidated financial statements for external
purposes in accordance with Canadian generally accepted accounting principles, including a reconciliation to U.S. GAAP.

Management
is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting, no matter how well designed, has inherent
limitations and can only provide reasonable assurance with respect to the preparation and fair presentation of published financial statements. Under the supervision and with the participation of the
President and Chief Executive Officer and the Chief Financial Officer, management conducted an evaluation of the effectiveness of its internal control over financial reporting based on the framework
in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based
on this evaluation, management concluded that internal control over financial reporting is effective as at December 31, 2009, to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external reporting purposes.

In
2009, there was no change in TransCanada's internal control over financial reporting that materially affected or is reasonably likely to materially affect TransCanada's internal control over
financial reporting.

KPMG LLP,
the independent auditors appointed by the shareholders of TransCanada, who have audited the consolidated financial statements of TransCanada, have also audited the effectiveness of
TransCanada's internal control over financial reporting as of December 31, 2009 and have issued the report entitled "Report of Independent Registered Public Accounting Firm".

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To
the Board of Directors of TransCanada Corporation

We
have audited TransCanada Corporation's internal control over financial reporting as of December 31, 2009, based on the criteria established in Internal
Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's
Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit
also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are
subject to the risk
that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In
our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal
Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We
also have conducted our audits on the consolidated financial statements in accordance with Canadian generally accepted auditing standards and in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Our report dated February 22, 2010 expressed an unqualified opinion on those consolidated financial statements.

COMMENTS BY AUDITORS FOR UNITED STATES READERS ON CANADA  UNITED STATES REPORTING DIFFERENCES

To
the Board of Directors of TransCanada Corporation

In
the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) that refers to the audit report on the Company's
internal control over financial reporting. Our report to the shareholders dated February 22, 2010 is expressed in accordance with Canadian reporting standards, which do not require a reference
to the audit report on the Company's internal control over financial reporting in the financial statement auditors' report.

In
the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when there is a change in accounting principles,
whether as a result of the adoption of a new accounting pronouncement or otherwise, that has a material effect on the consistency of the Company's financial statements, such as the change described in
note 3 to the consolidated financial statements as at December 31, 2009 and for the three-years then ended. Our report to the shareholders dated February 22, 2010 is
expressed in accordance with Canadian reporting standards, which do not require a reference to such a change in accounting principles in the auditors' report when the change is properly accounted for
and adequately disclosed in the financial statements.
