CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Changes in Internal Control Over Financial Reporting

During the year ended December 31, 2006, there was no change in the Canadian National Railway Companys internal control over financial reporting that has materially affected, or is
reasonably likely to materially affect, Canadian National Railway Companys internal control over financial reporting.

AUDIT COMMITTEE FINANCIAL EXPERT

The Registrants board of directors has determined that it has several audit committee financial experts serving on its Audit Committee. Mr. Hugh Bolton has been determined to be an audit
committee financial expert and is independent, as that term is defined by the New York Stock Exchanges listing standards applicable to U.S. Companies. The SEC has indicated that the designation or identification of Mr. Bolton as an audit
committee financial expert does not deem him an expert for any purpose, impose any duties, obligations or liability on Mr. Bolton that are greater than those imposed on members of the audit committee and board of directors who do not
carry this designation or identification, or affect the duties, obligations or liability of any other member of the audit committee or board of directors.

CODE OF ETHICS

The Registrant has adopted a code of ethics (the Code of Business Conduct) that applies to all employees and officers, including its principal executive officer, principal financial
officer and principal accounting officer. The Code of Business Conduct is available at the Registrants Internet website,www.cn.caunder the caption
Corporate Governance. Any amendments to the Code of Business Conduct will be posted at the Registrants Internet website at the address listed above.

  independent auditor. The Audit Committee pre-approved 100% of the services performed by our independent auditors for audit-related and tax fees for the year ended December 31, 2006 that were required to be pre-approved.





---



A discussion of the nature of the services provided under each category is provided below.

Audit fees

Consists of fees incurred for professional services
rendered by the auditors in relation to the audit of the Companys consolidated
annual financial statements and those of its subsidiaries, and for 2006 only,
the first audit relating to the Companys internal
control over financial reporting.

Audit-related fees

Audit-related fees were incurred for professional
services rendered by the auditors in relation to the audit of the financial statements
for the Companys pension plans, and for  attestation services in connection
with reports required by statute or regulation and due diligence and other services,
including comfort letters, in connection with the issuance of securities.

Tax fees

Consists of fees incurred for consultations on cross-border tax implications for employees and tax compliance.

All other fees

In 2005, the entire amount was incurred for consultations
with respect to the U.S. Sarbanes-Oxley Act of 2002, Section 404 Report
on Internal Controls.

OFF BALANCE SHEET ARRANGEMENTS

Accounts receivable securitization

The Company has a five-year agreement, expiring in May 2011, to sell an undivided co-ownership interest of up to a maximum of $600 million in a revolving pool of freight receivables
to an unrelated trust. Pursuant to the agreement, the Company sells an interest in its receivables and receives proceeds net of the required reserves as stipulated in the agreement.  This program replaced the Companys previous accounts
receivable securitization program that was set to expire in June 2006.

The Company has retained the responsibility for servicing, administering and collecting the receivables sold.  At December 31, 2006, the servicing asset and liability were not significant.
Subject to customary indemnifications, the trusts recourse is generally limited to the receivables.

The Company accounted for the securitization programs as sales, because control over the transferred accounts receivable was relinquished. Due to the relatively short collection period and the
high quality of the receivables sold, the fair value of the undivided interest transferred to the trust approximated the book value thereof.

The Company is subject to customary reporting requirements for which failure to perform could result in termination of the program. In addition, the trust is subject to customary credit rating
requirements, which if not met, could also result in termination of the program. The Company monitors the reporting requirements and is currently not aware of any trends, events or conditions that could cause such termination.

The accounts receivable securitization program provides the Company with readily available short-term financing for general corporate use.  In the event the program is terminated before its
scheduled maturity, the Company expects to meet its future payment obligations through its various sources of financing, including its revolving credit facility and commercial paper program, and/or access to capital markets.

At December 31, 2006, the Company had sold receivables that resulted in proceeds of $393 million under the new accounts receivable securitization program ($489 million at December 31,
2005 under the previous

---



program), and recorded the retained interest, which represents the required reserves, of approximately 10% ofthisamount in Other current assets (retained interest
of approximately 10% recorded at December 31, 2005).

Guarantees and indemnifications

In the normal course of business, the Company, including certain of its subsidiaries, enters into agreements that may involve providing certain guarantees or indemnifications to third parties
and others, which may extend beyond the term of the agreement.  These include, but are not limited to, residual value guarantees on operating leases, standby letters of credit and surety and other bonds, and indemnifications that are customary for
the type of transaction or for the railway business.

The Company is required to recognize a liability for the fair value of the obligation undertaken in issuing certain guarantees on the date the guarantee is issued or modified. In addition,
where the Company expects to make a payment in respect of a guarantee, a liability will be recognized to the extent that one has not yet been recognized.

The nature of these guarantees
or indemnifications, the maximum potential amount of future payments, the carrying
amount of the liability, if any, and the nature of any recourse provisions are
 disclosed in Note 18  Major commitments and contingencies, to the Companys
 2006 Annual Consolidated Financial Statements.

|ITEM 3 | GENERAL DEVELOPMENT
          OF THE BUSINESS
|------ | ---------------------------------------------

|    |         
|--- | --------
|3.1 | OVERVIEW

CN is engaged in the rail and related transportation
    business. As of December 31, 2006, CN operated approximately 20,300 route
    miles. This includes 14,000 route miles in eight Canadian provinces and the
    Northwest Territories as well as approximately 6,300
    route miles in sixteen U.S. states, with principal routes to every major
    metropolitan area in Canada and to the major U.S. rail hubs of

Buffalo, Detroit, Duluth/Superior, Minneapolis/St.
Paul, Chicago, St. Louis, Jackson, Memphis, New Orleans, Baton Rouge and Mobile.
The Company spans Canada and mid-America, serving all five major Canadian ports
on the  Atlantic and Pacific oceans and the Great Lakes as well as New Orleans
on the Gulf of Mexico.

The Companys freight revenues are derived from seven commodity groups, representing a diversified and balanced portfolio of goods transported between a wide range of origins and destinations. In 2006, the largest
commodity group accounted for approximately 23% of revenues. From a geographical standpoint, in 2006, 22% of revenues came from U.S. domestic traffic, 32% from transborder traffic, 23% from Canadian domestic traffic, and 23% from overseas traffic.

CN originated approximately 87% of traffic moving along its network in 2006. This allows the Company both to capitalize on service advantages and to build on opportunities to efficiently use assets.

|3.2 | GENERALDEVELOPMENT OF THEBUSINESSDURING THELASTTHREEYEARS
|--- | ---------------------------------------------------------

CNs goal is to grow the
    business profitably, creating value for its customers and generating an adequate
    and sustainable return on capital invested. To reach
    that goal, CN focuses on strategies and initiatives that allow it to continually
    improve service, seize upon a range of business opportunities, and achieve
productivity gains throughout the organization.

The initiatives undertaken by CN in the last three
years to achieve its growth and profitability goals and to enhance shareholder
value can be grouped into a few key areas. These include acquisitions
and dispositions, targeted capital investment spending and other initiatives
to strengthen the Companys position in the marketplace, cooperation and
co-production agreements with other carriers, as well as financial management
initiatives as  described below:

2006 HighlightsAcquisitions and Dispositions

In 2006, CN made the following acquisitions for a total cost of $84 million paid in cash:

On January 19, 2006, CN completed the purchase of the Alberta short-line railways owned by RailAmerica, Inc., of Boca Raton, Florida. CN bought the 600-mile Mackenzie Northern Railway (MKNR) and the 118-mile Lakeland
& Waterways Railway (LWR), both located north of Edmonton, along with the 21-mile Central Western Railway (CWR) in east-central Alberta that carries agricultural traffic. These feeder lines are a good fit for CNs merchandise and bulk
commodity groups at a time of major energy project development in northern Alberta.

In March 2006, CN acquired the remaining 51% of SLX Canada Inc., a company engaged in equipment leasing in which the Company previously had a 49% interest that had been consolidated with its results.

On December 1, 2006, CN completed the purchase of Savage Alberta Railway, Inc. (SAR), a 345-mile short-line railway, from Savage Companies of Salt Lake City, Utah. The acquisition represents an opportunity for CN to
solidify its freight franchise in resource-rich north-western Alberta.

Strategic Initiatives and Capital Spending

In 2006, CN spent more than $1.5 billion on
capital programs, an increase of eleven per cent over 2005 spending. This included
approximately $1 billion spent on infrastructure, replacing rail, ties, ballast,
 and other track material and upgrading bridges and signalling systems, as well
as network productivity initiatives and strategic projects, including siding
extensions in western Canada, investments in the Company's Prince Rupert, British
Columbia, corridor, and the

reconfiguration of Johnston Yard in Memphis, Tennessee.
Equipment spending of approximately $350
million in 2006, was for the acquisition of new locomotives, the rejuvenation
of the existing locomotive fleet, the acquisition of new cars and the refurbishment
of the current fleet to meet customer needs. CN also spent approximately $200
million on facilities, information technology and other projects to allow the
Company to tap new growth opportunities and drive overall efficiency gains.

Through 2006, CN continued to take delivery of 75 high-horsepower locomotives ordered in April of 2005, leaving just 15 of the original order to be delivered in the latter half of 2007. Also in 2006, the Company
exercised its option to acquire an additional 50 high-horsepower locomotives for delivery in the second half of 2007. The 75 new locomotives of 4,300  4,400 horsepower allow CN to replace 100 older 3,000-3,600 horsepower road locomotives. The
new units are almost 20 per cent more fuel-efficient than the ones replaced. The additional 50 4,300-horsepower locomotives to be delivered in 2007 will allow CN to tap growth opportunities, including new international freight traffic to and from
the Port of Prince Rupert intermodal terminal.

Significant Cooperation Agreements

As part of an ongoing effort to improve productivity
and capacity, CN periodically enters into cooperation agreements with other carriers,
including track and infrastructure exchanges, co-production, haulage and track
 access agreements, as well as routing protocols that endeavour to emphasize
more efficient interchanges that bypass congested terminals. In 2006, CN concluded
several such agreements, including the following in January 2006:

- CN and BNSF Railway Company (BNSF) concluded an agreement covering several key locations where their respective networks interact including, in
particular, the Vancouver, B.C., Chicago, and Memphis to southern Illinois regions;
- CN and Canadian Pacific Railway Company (CPR)
    concluded an agreement intended to make rail operations
    more fluid in British Columbias Lower Mainland,
enhancing service for rail customers and supporting
the growth of Pacific Gateway ports and terminals; and
- CN and CSX Transportation, Inc., (CSXT)
    concluded a long-term agreement to haul CSXT
    traffic to and from Sarnia, Ont., and CSXT connections in Buffalo,  New York,
    and Toledo, Ohio.

Financial Management Initiatives

On May 9, 2006, the Company filed a shelf prospectus
and registration statement, expiring in June 2008, which provides for the issuance,
from time to time, of up to U.S.$1,500 million of debt securities in one
or more offerings in the Canadian or U.S. markets for general corporate purposes.
Pursuant to the filing, on May 31, 2006, the Company
issued U.S.$250
million (Cdn$275 million) of 5.80% Notes due 2016 and U.S.$450 million
(Cdn$495
million) of  6.20% Debentures due 2036. The Company used the net proceeds of
U.S. $692 million to reduce its accounts receivable securitization program
and to repay a portion of its outstanding commercial paper.

On May 31, 2006, the Company entered into an agreement, expiring in May 2011, to sell an undivided co-ownership interest of up to a maximum of $600 million in a revolving pool of freight receivables to an unrelated
trust. This new program replaces the Companys previous accounts receivable securitization program that was set to expire in June 2006.

On July 15, 2006, the interest rate on the Companys
U.S.$250 million Puttable Reset Securities PURSSM(PURS)
was  reset at a new rate of 6.71% for the remaining 30-year term ending July
15, 2036. The PURS were originally issued in July 1998 at the rate of 6.45% with
an option to call the securities on July 15, 2006 (the reset date). The call
option holder  exercised the call option, which resulted in the remarketing of
the original PURS. The new interest rate was determined according to a pre-set
mechanism based on prevailing market conditions. The Company did not receive

5

---



any cash proceeds from the remarketing. The remarketing did not trigger an extinguishment of debt, as the provisions for the reset of the interest rate were set forth in the original PURS. As such, the original PURS
remain outstanding but accrue interest at the new rate until July 2036.  Under securities laws, the remarketing required utilization of the Companys shelf prospectus and registration statement. As such, following the issuance of debt on May
31, 2006 and the remarketing of debt as explained herein, the amount available under the shelf prospectus and registration statement has been reduced to U.S.$550 million.

In July 2006, the Board of Directors of the Company approved a new share repurchase program which allows for the repurchase of up to 28.0 million common shares between July 25, 2006 and July 24, 2007 pursuant to a
normal course issuer bid, at prevailing market prices. As at December 31, 2006, 15.5 million common shares have been repurchased for $766 million, at an average price of $49.43 per share. The Companys previous share purchase program,
initiated in 2005, allowed for the repurchase of up to 32.0 million common shares between July 25, 2005 and July 24, 2006 pursuant to a normal course issuer bid, at prevailing market prices. In June 2006, the Company ended this share repurchase
program, having repurchased a total of 30.0 million common shares for $1,388 million at an average price of $46.26 per share. Of this amount, 14.0 million common shares were repurchased in 2006 for $717 million (average price per share
of $51.24) and 16.0 million common shares in 2005 for $670 million (average price per share of $41.90) .

2005 Highlights

Strategic Initiatives and Capital Spending

In 2005, CN spent $1.4 billion on capital additions. The Company continued to focus infrastructure capital toward a safe, reliable and fluid network. In particular, CN invested in further siding extensions on its
line west of Edmonton to accommodate growing volumes, to improve network velocity and to run longer trains. CN also partnered with the Port of Prince Rupert and Maher Terminals of Canada Corporation (Maher Terminals) in the development
of the Fairview intermodal container terminal at Prince Rupert, which is expected to become an important gateway for trade between North America and Asia. CN also spent in excess of $300 million on rolling stock in 2005 with a view toward
building a more homogeneous fleet of high-capacity cars, driving both customer-service quality and distribution efficiencies. CN took delivery of 750 new centerbeams and 500 new Plate F boxcars by the end of 2005. Modernization of the locomotive
fleet continued in 2005  as discussed under the 2006 Highlights herein. CNs information and communication technology investment in 2005 was in line with 2004 spending, with the primary focus on base computing and communication infrastructure,
integration of BC Rail and GLT, and the maximization of value obtained from its SAP Enterprise system.

On April 29, 2005, with $60 million in funding for the new Port of Prince Rupert container terminal secured from the Canadian and British Columbia governments, CN, Maher Terminals and the Prince Rupert Port
Authority announced plans to make the new terminal a reality in 2007. CNs investment in the new terminal includes an amount of $15 million for the intermodal yard at the port, $10 million for the terminal trackage, and $5-$10
million for infrastructure improvements to CN's B.C. North line to accommodate double-stack container cars. Maher Terminals contribution includes funds for the acquisition and installation of three large container cranes at the terminal,
together with supporting container-handling equipment and technology, at a cost of approximately $60 million. The Prince Rupert Port Authority undertook to contribute $25 million to the container terminal development.

Phase 1 of the terminal development--expected to provide initial throughput capacity of up to 500,000 TEUs (twenty-foot equivalent containers) per year-- is part of a broader plan to build a facility capable of
handling two million TEUs per year. Strategically located at the North American entry point of the North West Transportation Corridor, the Port of Prince Rupert links the fast-growing Asian markets to one of the world's largest industrial and
consumer markets. With modern terminals and the availability of vast industrial development property, congestion-free facilities provide transit time and cost-saving opportunities for shippers and producers. Superior connections mean efficient
access to

6

the North American continent. With the deepest harbour in North America, the Port of Prince Rupert is set for continuous activity catering to the world's progressively larger container vessels.

In May 2005, CN formed CN WorldWide, a wholly-owned
subsidiary to offer international freight forwarding services between Europe
and North America to allow CN to provide shippers an integrated, door-to-door
freight  service, and position it to drive new containerized traffic through
CN-served ports in North America. CN WorldWide is based in Rotterdam, Netherlands,
the largest container port in the world outside of Asia. It schedules and manages
the door-to-door  movement of international shipments, including rail, trucking,
maritime transportation and port handling, along with warehousing, customs and
billing. Still in its start-up phase, CN WorldWide is focused on expanding its
service offering. Initially  targeting shipments between Europe and eastern Canada,
including Ontario and Québec, via the Port of Halifax, and the United States,
CN WorldWide has since added offices in Shanghai, Beijing and Shenzhen, China
to expand its coverage to Asia, as  well as offices in Sofia, Bulgaria and Milan,
Italy. Customs clearance for Canadian and U.S.-bound traffic was added to the
service offering of CN WorldWide starting in April 2006. This service provides
an additional attraction to customers while  improving CNs rail network
fluidity by expediting clearance of customer shipments.

Significant Cooperation Agreements

Expanding on CNs routing protocol initiative with connecting carriers that began in 2004, CN concluded routing protocol agreements to streamline the exchange of rail traffic at major gateways. Under the
protocols, rail traffic flows are directed through the most efficient interchange locations to improve transit times and asset utilization for the customers of participating carriers. Among others, the following agreements were finalized in
2005:

- In January 2005, CN and BNSF signed a comprehensive routing protocol agreement covering multiple locations on each carriers respective network, including Noyes, Minnesota,
Memphis, Tennessee, and New Orleans, Louisiana; and
- In March 2005, CN and Norfolk Southern Railway (NS) announced a structured routing protocol to streamline their exchange of rail traffic at major gateways, including
Rouses Point, New York, Memphis, Tennessee, and New Orleans, Louisiana.

Financial Management Initiatives

As mentioned in the 2006 Highlights, in July 2005, the Board of Directors of the Company approved a share repurchase program, which allowed for the repurchase of up to 32.0 million common shares between July 25, 2005
and July 24, 2006, pursuant to a normal course issuer bid, at prevailing market prices. As at December 31, 2005, 16.0 million common shares had been repurchased for $670 million, at an average price of $41.90 per share.

The Companys previous share repurchase program, initiated in 2004, allowed for the repurchase of up to 28.0 million common shares between November 1, 2004 and October 31, 2005, pursuant to a normal course issuer
bid, at prevailing market prices. By the second quarter of 2005, the Company had completed this share repurchase program, repurchasing 28.0 million common shares for $1,021 million, at an average price of $36.47 per share (20.0 million and
8.0 million in 2005 and 2004, respectively).

2004 HighlightsAcquisitions and Dispositions

In January 2004, the shareholders of English Welsh and Scottish Railway Holdings Limited (EWS), a company which provides most of the rail freight services in Great Britain and operates freight trains
through the English

7

---



Channel tunnel, approved a plan to reduce the EWS share capital to enable cash to be returned to the shareholders by offering them the ability to cancel a portion of their EWS shares in exchange for a combination of
cash and notes receivable.  The Company elected to have the maximum allowable number of shares cancelled under the plan, thereby reducing its ownership interest in EWS to approximately 31% on a fully diluted basis (13.7 million shares) compared to
approximately 37% on a fully diluted basis (43.7 million shares) prior to the capital reorganization. In the first quarter of 2004, the Company received £57.7 million (Cdn$141 million) in cash and an 8% note receivable due 2009 of
£23.9 million (Cdn$58 million) from EWS.  In April 2005, EWS fully redeemed the Companys note receivable. The Company received £26 million (Cdn$61 million), which included principal and accrued but unpaid interest to the date
of redemption.

On May 10, 2004, CN completed the acquisition
of GLT, including two railroads and a rail switching company at an acquisition
cost of U.S.$395 million (Cdn$547 million). The acquired railroads were:
the 212-mile  Duluth, Missabe and Iron Range Railway Company ("DMIR"), a Class
II railroad that is a common carrier of pelletized iron ore in Minnesota and
Wisconsin; the Class II Bessemer and Lake Erie Railroad Company (BLE),
which carries  primarily coal, iron ore and limestone between the Lake Erie port
of Conneaut, Ohio, and steel mills in the Pittsburgh area; and the Pittsburgh & Conneaut
Dock Company ("PCD") - a Class III switching railroad that performs ship-to-rail
 and rail-to-ship bulk transfer operations for the BLE at three docks at
 Conneaut. As part of the transaction, CN also acquired Great Lakes Fleet, Inc.
 - a non-railroad company with eight Great Lakes vessels transporting bulk commodities,
  principally for the United States steel industry. Under a demise charter and
 vessel management agreement, Keystone Shipping Co. of Bala Cynwyd, Pennsylvania,
 operates the ships. The acquisition of GLT strengthens CNs position as
 a  transportation service provider to the steel industry, in addition to driving
 new efficiencies in the network by giving the Company ownership of an essential
 link in the important Chicago-Winnipeg corridor.

On July 14, 2004, CN completed its acquisition of all the issued and outstanding shares of the former BC Rail Ltd., all the partnership units of BC Rail Partnership, and the right to operate over BC Rails roadbed
under a long-term lease, for an acquisition cost of $991 million. The acquisition of BC Rail extends CNs business reach in western Canada and opens up growth opportunities, particularly in the Companys forest products
franchise.

In 2004, CANAC Inc. and Beltpack Corporation, subsidiaries of CN involved in railroad operations consulting services and remote control locomotive technology, respectively, were sold for net proceeds of $52
million.

Significant Cooperation Agreements

In January 2004, CN and CSXT announced a jointly-developed electronic tool offering customers instantaneous interline prices for carload shipments moving over their networks. The tool, called "A+B Pricing," uses Web
Services Internet technology, and allows railroad account managers to retrieve and combine CN's and CSXT's revenue requirements to quote market competitive interline prices in real time for any origin, destination and commodity on the two rail
systems. This enables customers to go to the originating railroad's web site and ask for a combined interline price. Immediate access to competitive interline pricing makes shipping via CN and CSXT easier and more accurate, and represents another
step in making the railroads an attractive option to freight currently moving over North America's highways. This tool has since been expanded to include, to varying extents, BNSF, NS, Union Pacific Railroad (UP) and CPR.

In October 2004, CN and CPR announced a series of co-production agreements to make rail operations more efficient for Port of Vancouver freight traffic.

In November 2004, CN entered into the following agreements:

| |  | CN, CPR and NS announced an
        agreement to improve freight service between eastern Canada and the eastern
        United States. The three-party arrangement gave CN and NS a seamless,
    direct north-south routing

| |   | over CPRs lines south of Montreal
      that eliminated up to two days transit time from approximately 20,000
      annual shipments.

| |  | CN and CPR reached an agreement on three
      new network initiatives to improve railway transit times and asset
      utilization in British Columbia, Alberta and Ontario. The initiatives included
      a slot-sharing arrangement for bulk
      commodities over CPRs network in Alberta and B.C., directional running
      in northern Ontario, and a haulage
      agreement permitting the rationalization of 200 miles of CN secondary track
      between Thunder Bay and Long Lac,
      Ontario.
| |   |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
| |  | CN and UP concluded a routing protocol agreement
      to streamline their exchange of rail traffic at major gateways
      helping to reduce rail congestion at Chicago.                                                                                                                                                                                                                                                                                                                                       

Strategic Initiatives and Capital Spending

In 2004, CNs capital expenditures amounted to $1.2 billion. The largest portion of CNs capital expenditures (approximately $770 million) was for rail infrastructure to preserve the quality and
integrity of the plant, to provide safe and reliable service to its customers across Canada and the U.S. and to improve network efficiency and fluidity through  siding extensions and signalling improvements, particularly in the western
Canada/Chicago corridor. Investment in rolling stock was approximately $250 million in 2004, including significant refurbishment of both the hopper car fleet and the car fleet used in the transport of metals. The refurbishment programs  as
well as significant additions of new cars (centerbeams, box cars and multi-levels) through leases, allowed CN to respond to strong market demand. The Company also continued its locomotive fleet modernization program with the acquisition of 60 new
high-horsepower, fuel-efficient units. CN spent over $80 million on information and communications technology in 2004 to ensure a smooth integration of BC Rail and GLT systems, and to drive eCommerce initiatives as well as the continued upgrade
of the SAP Enterprise systems. Finally, the Company invested in facilities upgrades, including the construction of a new $30 million state-of-the-art intermodal terminal in Memphis.

In October 2004, CN established a presence in China through the opening of offices in Shanghai and Beijing. In October 2006, CN WorldWide announced the launch of its international freight forwarding operations in China
with offices in Shanghai, Beijing and Shenzhen. Together, these offices employ representatives whose aim is to grow the railway's share of rising traffic flows between China and North America by helping to identify profitable opportunities for
transporting bulk and merchandise commodities destined for China, and handling two-way trade in products transported in containers. CN intends to use its presence in China to push and pull growing China-North America trade over its network in Canada
and the United States via the important ports of Vancouver, Halifax, Montreal and New Orleans.

Financial Management Initiatives

On July 9, 2004, CN closed a U.S.$800 million debt offering composed of U.S.$300 million (Cdn$395 million) 4.25% Notes due 2009, and U.S.$500 million (Cdn$658 million) 6.25% Debentures due 2034. CN
used the net proceeds of U.S.$790 million to finance a portion of the acquisition costs of BC Rail and GLT. The debt offering was made in the United States under the shelf prospectus and registration statement CN filed in October 2003 for the
issuance of up to U.S.$1 billion of debt securities.

As mentioned in the 2005 Highlights, in October 2004, CNs Board of Directors approved a share repurchase program, which allowed for the repurchase of up to 28.0 million common shares, pursuant to a normal course
issuer bid, at prevailing market prices. This share repurchase program that began on November 1, 2004 was completed in June 2005, with 28.0 million common shares repurchased for $1,021 million at an average price of $36.47 per share.

|  | The Western Region extends from Thunder
          Bay and Armstrong in northwestern Ontario to the Pacific Ocean.
          This Region of approximately 9,500 route miles of track serves the
          Port of Vancouver, the inland port
          of Thunder Bay and is the exclusive rail link to Prince Rupert, the
          closest North American port to Northeast
          Asia. The Region is also home to the Alberta oil sands deposits that
          contain much of the worlds known
          total bitumen reserves, including the Athabasca oil sands along the
          Athabasca River just north of the city of Fort McMurray (the oil sands). CN benefits
          from its unique access to this area. In the Western Region,
          CN carries bulk export commodities such as grain and fertilizers, coal,
          potash and sulfur, as well as forest
          products, petroleum and chemicals, and intermodal destined for international
          and North American domestic markets.
          CN also carries metals, machinery and construction materials in this
          Region to serve the oil sands
        development.

|    | The Southern Region
        extends from International Falls just south of Fort Francis, Ontario,
        to Chicago, Illinois, then on to New Orleans, Louisiana, on the Gulf
        of Mexico, and from Minneapolis and St. Paul, Minnesota to Sault
        Ste. Marie, Michigan, and from Sioux City, Iowa and Omaha, Nebraska heading
        east to Port Huron and Detroit,
        Michigan. This Region of approximately 6,300 route miles of track serves
        the Gulf ports of Mobile, Alabama
        and New Orleans, Louisiana, and the river ports of Memphis, Tennessee
        and Baton Rouge, Louisiana. Major
        commodities transported include automotive, iron ore and steel, petroleum
        and chemicals, forest products,
        coal, fertilizers and grain. The Region interchanges traffic with Kansas
        City Southern Railroad (KCS) at Jackson, Mississippi, as
        part of the marketing alliance that provides CN customers access
        to Mexico and the U.S. Southwest. With connections in Chicago and other
        locations to all North American
        Class I  carriers,
        the Southern Region serves as a critical link to the rest of the U.S.
    market.

The following describes the various commodity groups transported by CN:

|4.2.1 | Petroleum and chemicals
|----- | -----------------------

The petroleum and chemicals commodity group includes
a wide range of commodities, which can be divided into the following categories:
chemicals, representing 40% of the commodity groups revenues in 2006, and
plastics, sulfur, petroleum and natural gas products, representing 60% of the groups revenues for the year.

Although offshore markets have been growing strongly, the primary markets are still within North America, and the performance is closely correlated with the North American economy. The consolidation and rationalization
of industrial production facilities have resulted in increased rail-based business opportunities in both the Canadian and U.S. markets.

This group of commodities is a strong originator of traffic. CN has access to northern Alberta, a major center for natural gas, feedstock and world scale petrochemicals and plastics complex derivatives.

The Company also enjoys access to the Louisiana petrochemical corridor between New Orleans and Baton Rouge and a large number of eastern Canadian regional plants. CN provides a highly efficient route to the large
consuming areas in the Midwest and Northeast of the United States.

|4.2.2 | Metals and minerals
|----- | -------------------

The metals and minerals commodity group comprises
metals, representing 55% of the commodity groups revenues in 2006, equipment
and parts, and construction materials, representing 25%, and iron ore, representing
 20% of the groups revenues for the year. CNs unique rail access
 to major mines, ports and smelters makes it a leader in the transportation of
 copper, lead, zinc concentrates, iron ore, refined metals and aluminum. Copper
 and zinc  commodities, such as ores, concentrates and anodes are produced in
 northern Québec, Ontario and Manitoba. The commodities are shipped to refineries
 for further processing and then shipped to manufacturers of finished goods.

Major producers of steel, primarily in Ontario and the U.S. Midwest, ship their products throughout North America and Mexico. Such products are mainly used in the automotive and construction industries.

Construction materials are mainly aggregates (stone and sand) and cement. CN enjoys access to major cement producers and aggregate mines in Canada as well as in the U.S.

CNs metals and minerals traffic is sensitive
to fluctuations in the economy. CN serves a variety of major industries along
its network and has the most direct route to the Ports of New Orleans and Mobile
from the Midwest, as well as an efficient route into Mexico via its marketing
alliance with KCS.

World energy consumption and Canadas stable political environment have combined to drive unprecedented investment and development activity in the oil sands of northern Alberta, providing CN with significant
opportunities in the metals, machinery, dimensional loads, and construction materials segments.

|4.2.3 | Forest products
|----- | ---------------

12

---



The forest products commodity group consists of
four major commodity segments: lumber accounted for 34% of the commodity groups revenues in 2006, fibers 31%, paper 22%, and panels 13% of the groups revenues
for the year.

The key drivers for newsprint are advertising
lineage and overall economic conditions, primarily in the United States. For
fibers (mainly woodpulp), the consumption of paper worldwide is the key driver.
Housing starts and renovation activities in the United States are the key drivers
for the lumber and panels traffic.

The ability to provide consistent, reliable service gives railroads the opportunity to convert traffic from truck to rail. Demand for forest products tends to be cyclical and this commodity group may be impacted by the
recent slowdown in home construction in North America.  Nevertheless, CN believes that its geographical advantages and product diversity tend to reduce the impact of market fluctuations. CNs scheduled service offering and guaranteed car order
program have also been significant contributors to growing CNs share of this traffic.

|4.2.4 | Coal
|----- | ----

Of the coal traffic moved by CN in 2006, 49% originated in Canada and 51% in the United States, with coal providing 86% of the commodity groups revenues for the year and petroleum coke 14%.

CNs coal business consists primarily of thermal grades of bituminous coal. Canadian thermal coal is delivered to power utilities primarily in eastern Canada. In the United States, shipments of U.S. thermal coal
are transported from mines served in southern Illinois, or from western U.S. mines via interchange with other railroads, to major utilities in the Midwest and southeast United States. CN has been able to aggressively market seamless service options
through connections with western rail carriers. This strategy has allowed CN to stabilize volumes and target growth areas.

The coal business also includes Canadian metallurgical coal, which is generally exported to steel makers in Japan and other Asian markets from three coal terminals in British Columbia. The global market for
metallurgical coal, driven primarily by Asian demand, has facilitated the opening of four mines along the CN network in late 2004. The improvement in this market is expected to continue as strong Asian demand for metallurgical coal is driving
increased Canadian production.

|4.2.5 | Grain and fertilizers
|----- | ---------------------

This commodity group depends primarily on crops
grown and fertilizers processed in western Canada and the U.S. Midwest. Of the
grain traffic moved by CN in 2006, 61% originated in Canada, almost all in the
west, and  39% in the United States.

The grain segment, which represents 82% of the commodity groups 2006 revenues, consists of three primary commodities: food grains, mainly wheat, representing 34% of the grain segments revenues in 2006;
oilseeds and oilseed products (primarily canola seed, oil and meal) 33%; and feed grains (including feed barley, feed wheat and corn), 33% of the groups revenues for the year.

The vast majority of the grain produced in western Canada is exported. Production of grain in Canada varies considerably from year to year, affected primarily by weather conditions. Grain exports are volatile,
reflecting the size and quality of the crop produced, international market conditions and foreign government policy. The majority of the Western Canadian grain moved by CN is exported via the ports of Vancouver, Prince Rupert, B.C., and Thunder Bay,
Ontario. Certain of these rail movements are subject to government regulation and to a revenue cap, which effectively establishes a maximum revenue entitlement that railways can earn.

In the U.S., the CN rail system is well positioned in the heart of the grain-producing territory. Two of the states to which CN has direct access, Illinois and Iowa, have had historically the largest annual production
of corn and

13

---



soybeans. This allows CN to serve large grain processors in Illinois, Iowa, Tennessee, and Mississippi. Other domestic grain movements are to the poultry feeder markets in the southeastern United States, which rely on
corn for feed. Exports of grain and grain products represent another market for CN due to its access to major export facilities on the Mississippi River and the Gulf of Mexico.

Some of the worlds largest grain companies have processing plants located on the CN system. As a result, much of the grain traffic in which CN participates involves the movement of grain products that are
produced and then shipped to other receiver markets. Soybean meal, corn gluten feed, vegetable oils, corn syrups and starches are some of the products moved by CN.

Fertilizers and potash represent 18% of this commodity groups 2006 revenues. CN is a significant player in the Canadian rail market for nitrogen-based fertilizers, with production centered primarily in western
Canada. CN serves or has access to all major potash mines in Saskatchewan, the center for western Canadian production. CN also serves a major production facility on Canadas east coast. Virtually all Canadian potash moves by rail to markets in
the U.S. or overseas. In the United States, CN serves producers of various types of fertilizers, including nitrogen solutions, ammonium nitrate, urea and phosphate fertilizers. U.S. and Canadian fertilizer production is heavily impacted by the price
of natural gas that is a main raw material for most fertilizer production. When gas prices are high, many of the local producers reduce production. At the same time, imports can become more competitive and CN is positioned to handle this business
through access to Gulf ports in Louisiana.

|4.2.6 | Intermodal
|----- | ----------

This commodity group is comprised of the following two segments:

Domestic, which represented 48% of the commodity groups revenues in 2006, includes domestic Canada, transborder, Mexico and domestic U.S. traffic. Domestic provides
intermodal services through a number of channels in which services are retailed directly to beneficial owners of freight, and wholesaled to motor carriers, intermodal marketing companies, third-party logistics companies and other transportation
intermediaries. The Domestic segment is driven by consumer markets, with market growth generally expected to be tied to the economy. The service is market-driven and very competitive with the trucking industry. The segments focus is to define
its services as truck competitive and cost-effective.

International, which represented 52% of the commodity groups revenues in 2006, transports import/export container business on behalf of ocean carrier companies. Within
Canada, CN ships from/to the ports of Vancouver, Montreal, St. John and Halifax. In the United States, CN ships from/to the ports of New Orleans and Gulfport and via rail connections at Chicago and Detroit to both the U.S. East and West Coast ports.
Key growth markets for the international segment have been between the ports of Vancouver and Montreal and locations in the Midwest. Connections with other Class I  railways
in Chicago have further extended the reach of CNs international business into the U.S. Southeast. The international segment is driven mainly by North American economic conditions and shifting trade patterns between countries.

CN continues to reap the benefits of its IMX program to smooth traffic flows, increase speed and reliability, and improve asset utilization and margins. IMX applies the discipline and precision of scheduled railroading
to intermodal transportation.  With IMX, shippers are required to make reservations for spots on trains, while day-of-the-week pricing encourages the traffic to shift to off-peak days. This, in combination with required gate reservations at
CNs largest terminals, enables CN to align traffic with equipment and gate capacity and to improve speed and asset utilization. As a result of IMX, CN is seeing improvements in profit margins and CNs customers are benefiting from
improvements in speed and service reliability.

14

---



|4.2.7 | Automotive
|----- | ----------

CN is a leading carrier of automotive products originating in southern Ontario, Michigan and Mississippi and moves finished vehicles and parts within Canada and the United States and in both directions across the
border. The principal commodities within the automotive unit are finished vehicles, with 85% of the commodity groups revenues in 2006, and automotive parts, with the remaining 15%.

CNs automotive revenues are closely correlated to automotive production and sales in North America. CN can access traffic from all Canadian vehicle assembly plants, nine assembly plants in Michigan and one in
Mississippi. CN also has access to parts production facilities in both the U.S. and Canada. CNs
broad coverage enables it to consolidate full trainloads of automotive traffic
for delivery to connecting railroads at key interchange points. CN has the most
direct rail link from southern Ontario to the Chicago gateway, providing efficient
service in this time-sensitive sector. The Paul M. Tellier Tunnel provides the
ability to handle the tallest multi-level vehicle carriers as well as maximum
clearance for stacking vehicle frames. CN also offers single-line service through
Chicago to a variety of other interchange locations for automotive traffic and
CNs marketing alliance with KCS provides automotive customers with
single-line service between facilities in Canada and Mexico. CN also serves shippers of import vehicles via the ports of Halifax and Vancouver, and through interchange with other railroads.

|4.3 | LABOR
|--- | -----

Our ability to deliver quality service, efficient operations, and profitable growth depends on the presence of a qualified and experienced workforce. CN assesses workforce requirements on an ongoing basis.  While the
demographic profile of our employees going forward calls for detailed workforce planning, it also opens up opportunities to challenge how we do things and find new avenues to improve productivity.

As of December 31, 2006, CN employed a total of 15,232 employees in Canada and 6,579 employees in the United States.

For a discussion of CNs labor negotiations, see section 4.7.3.

|4.4 | SOCIAL POLICIES
|--- | ---------------

In addition to its Employment
    Equity Policy (for Canadian employees) and an Equal Employment Opportunity
    Policy (for American employees), CN maintains a comprehensive Human Rights
    Policy for Canadian employees at CN. These policies affirm CNs commitment
    to ensuring that there is no discrimination against any employee or applicant
    based on grounds of religion, race, sex, nationality, disability or any other
    prohibited grounds of discrimination. The policy extends to recruitment,
    selection and compensation practices, as well as to working conditions and
    the work environment. All Company vice-presidents have been mandated with
    the responsibility of implementing these policies and ensuring that all work
    practices are in compliance. Internal complaint procedures have been established
    whereby any person covered by the Equal Employment Opportunity Policy can
    address their questions or concerns to their supervisor and/or human resources
manager who will address their complaints.

|4.5 | REGULATION
|--- | ----------

The Companys rail operations in Canada are subject to (i) regulation as to rate setting, level of service, and network rationalization by the Canadian Transportation Agency (the Agency) under theCanada Transportation Act(Canada) (the CTA), and (ii) safety regulation by the federal Minister of Transport under theRailway Safety Act(Canada) and certain other statutes. The Companys U.S. rail operations are subject to (i) economic regulation by the Surface Transportation Board (the
  STB) and (ii) safety regulation by the Federal Railroad Administration (the FRA).
  As such, various Company business transactions must gain prior regulatory approval,
  with attendant risks and uncertainties, and the Company is subject to government
  oversight with respect to rate and service issues.

15

---



The Company is also subject to a variety of health,
safety, security, labor, environmental and other regulations, all of which can
affect its competitive position and profitability.

The Companys ownership of the former Great Lakes Transportation vessels is subject to regulation by the U.S. Coast Guard and the Department of Transportation, Maritime Administration, which regulate the ownership
and operation of vessels operating on the Great Lakes and in U.S. coastal waters.

With respect to safety, rail safety regulation in Canada is the responsibility of Transport Canada, which administers the CanadianRailway Safety Act, as well as the rail portions of other safety statutes. In addition, safety matters related to security are overseen by the Transportation Security Administration (TSA), which is part of the U.S. Department of Homeland
Security and the Pipeline and Hazardous Materials Safety Administration (PHMSA), which, like the FRA, is part of the U.S. Department of Transportation.

|4.5.1 | Canadian Regulation
|----- | -------------------

The CTA gives railroads in Canada the freedom to negotiate prices according to market forces, subject to certain provisions aimed at protecting shippers. These shipper protections include,inter alia, interswitching,
    final offer arbitration and competitive line rates. Pursuant to interswitching
    provisions, all shippers within a 30 km radius (approximately 19 miles) of
    an interchange between two federally regulated railroads have access to both
    at a prescribed interswitching rate. Final offer arbitration is used in cases
    of rate disputes between a shipper and a railroad and involves the selection
    by an arbitrator of either the shippers or the carriers rate
    and service offer. Competitive line rate provisions can be invoked to require
    an originating railroad to issue to a shipper with sole rail access, a rate
    covering the movement to the nearest junction with another railroad according
to predetermined formulae.

The CTA permits confidential contracts. Furthermore, railroads are subject to common carrier obligations for their services and, in case of breach, shippers may seek redress from the Agency. These shipper protections,
except for final offer arbitration, are, however, subject to the requirement for the applicant to demonstrate that the shipper would suffer substantial commercial harm if the Agency were not to intervene.

When a railroad operator wants to sell or abandon lines, the CTA encourages their sale to short-line operators and provides the framework for line abandonment. The railroads are required to publish a three-year plan
for sales and abandonments. For abandonment, the line must be advertised as being for sale to the public and, if no interest is shown, must be offered specifically for sale to applicable federal, provincial and municipal governments. The entire
process is intended to take at most 18 months. Legislation currently in force in the provinces of British Columbia and Saskatchewan requires a corporations successor by merger or purchase of assets to assume the predecessors labor
arrangements. These successor rights therefore limit the Companys ability to dispose of routes to intraprovincial short-line operators in such provinces. The Company has considered provincial successor rights legislation in
identifying routes for rationalization.

The Companys operations are also subject to safety and environmental provisions relating to track standards, equipment standards, transportation of hazardous materials, environmental assessments and certain labor
regulations, which are in many respects similar when comparing Canadian and U.S. regulations.

Periodically, a comprehensive review is made by the federal government of the effectiveness of the CTA and other statutes related to transportation. See section 4.7.3 for a further discussion of the last CTA
review.

|4.5.2 | U.S. Regulation
|----- | ---------------

The STB has jurisdiction over, amongst other things, service levels, carrier practices, car compensation, and limited jurisdiction over carrier rates. It also has jurisdiction over the situations and terms under which
one railroad may gain access to another railroads traffic or facilities, the construction, extension, or abandonment of rail lines, railroad consolidations, and labor protection provisions in connection with the foregoing. The STBs
jurisdiction in these areas of rail transportation, including intrastate rail transportation, is exclusive, pre-empting other remedies under federal and state law.

The FRA has jurisdiction over railroad safety and equipment standards, and most rail safety regulation is handled at the federal level. In contrast, however, to the exclusive role of the STB over railroad economic
regulation, state and local regulatory agencies have jurisdiction over certain local safety and operating matters and these agencies are becoming more aggressive in their exercise of jurisdiction. State legislatures have also recently enacted new
laws in this regard that are intended to regulate railroads more extensively.

Government regulation of the railroad industry is a significant determinant of the competitiveness and profitability of railroads. Deregulation of certain rates and services, plus the ability to enter into confidential
contracts, pursuant to theStaggers Rail Act of 1980(the Staggers Act), has substantially increased the flexibility of railroads to respond to market
forces and has resulted in highly competitive rates. Various interests have sought and continue to seek reimposition of government controls on the railroad industry in areas deregulated in whole or in part by the Staggers Act. Additional regulation,
changes in regulation and re-regulation of the industry through legislative, administrative, judicial or other action could materially affect the Company.

Following an extended review, in June 2001, the STB issued new regulations governing mergers between Class I Railroads. CN had recommended higher public interest standards for mergers and the new regulations
effectively raised the bar for the quality of customer service in all future major railroad mergers. The STB also agreed with CN that foreign-headquartered railroads would be treated the same as U.S.-based railroads under its merger
rules.

See section 4.7.3 for a further discussion of government regulation with respect, in particular, to Canada-U.S. Customs and U.S. Homeland Security.

|4.6   | ENVIRONMENTAL MATTERS
|----- | ---------------------
|      |                      
|4.6.1 |                      

A risk of environmental liability is inherent in railroad and related transportation operations; real estate ownership, operation or control; and other commercial activities of the Company with respect to both current
and past operations. As a result, the Company incurs significant compliance and capital costs, on an ongoing basis, associated with environmental regulatory compliance and clean-up requirements in its railroad operations and relating to its past and
present ownership, operation or control of real property. Environmental expenditures that relate to current operations are expensed unless they relate to an improvement to the property. Expenditures that relate to an existing condition caused by
past operations and which are not expected to contribute to current or future operations are expensed.

In Canada, the matter of environmental permits for the Company is complex because of an overlap between federal and provincial jurisdictions. When projects require approval by federal regulatory authorities,
environmental impact assessments are undertaken in accordance with federal requirements. Provincial and municipal environmental legislation may be applicable to railway activities if such legislation does not aim to regulate the management or
operations of railways. Therefore, the Company does not apply systematically for provincial, municipal or local environmental permits for its railway operations in Canada except (i) where obtaining and complying with such permits would not interfere
with the operations or management of its railway activities, (ii) where permitting issues were primarily of a provincial, municipal or local nature, (iii) where the Company or the governmental authority

17

---



thought it was necessary to obtain such permits to continue minor aspects of its railway operations or maintenance, or (iv) where the absence of a permit may affect a third party (such as a customer or a supplier).
Because of the multiple jurisdictions involved and the extensive provincial legislative authority to regulate environmental matters, there can be no assurance that additional provincial, municipal or local environmental permits will not be required
in the future. The Company may incur additional expenses or changes in its operations if such additional permits were to be required in the future.

See Note 18  Major commitments
  and contingencies, to the Companys Financial Statements,
  for a further discussion of  Environmental Matters as well as the section entitled
  Environmental Claims, on pages 25 and 26 of the MD&A. The Companys
  Financial Statements and MD&A
are available on SEDAR at www.sedar.com.

|4.6.2 | Environmental Policy
|----- | --------------------

CN is committed to conducting its operations and activities in a manner that protects the natural environment. CN considers protecting the environment a fundamental corporate social responsibility governing its
activities. Consequently, CN has implemented comprehensive environmental management programs.

CN makes the following commitments and expects its employees to act accordingly:

|1. | To integrate environmentally responsible actions throughout all significant aspects of CNs activities.                                                                                                                             
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|2. | To respect the applicable laws and regulations and adopt the required standards, procedures, contingency measures and management systems in order to ensure CN operations are managed safely, ecologically and in a
sustainable way.
|3. | To take necessary measures in order to prevent pollution, to conserve and use rationally the natural resources required for CN operations and implement relevant emergency response plans and procedures.                           
|4. | To communicate to management, employees and contractors CNs commitment to improving health, safety and the environment and to providing training adapted to their needs.                                                           
|5. | To systematically evaluate CNs environmental performance through appropriate audits and report progress.                                                                                                                           

|4.7   | LEGAL MATTERS
|----- | -------------
|      |              
|4.7.1 |              

As of February 12, 2007, the only legal proceedings, to which CN was a party, involving claims for damages in excess of 10% of its current assets, are described below. It is not currently expected, however, that such
  litigation proceedings will have a material adverse effect on the consolidated financial position or results of operations of CN. The Company will regularly assess its position as events progress.

In re African-American Slave Descendants Litigation

This matter is a slavery reparations case. The plaintiffs, a proposed class representing descendants of slaves, brought this action seeking payment for work performed by slaves between 1607 and 1865. The defendants
include numerous major corporations, among them CN, Norfolk Southern Corp., Union Pacific Corporation, CSX Corporation, Fleet Boston Financial Corp., Aetna Inc., Brown and Williamson Tobacco, Lehman Bros. Inc., Ligget Group Inc., New York Life
Insurance Company, R.J. Reynolds Tobacco Company, Society of Lloyds, Loews Inc. and JP Morgan Chase & Co.  The amount claimed would be in the trillions of dollars, some part of which would be claimed from IC, a subsidiary of CN. The Company is
contesting these proceedings.

CN was first named as a defendant in slavery reparations litigation in a complaint filed on September 4, 2002 in Louisiana.

18

---



The Louisiana complaint was consolidated in multi-district litigation proceedings in Chicago in the U.S. District Court for the Northern District of Illinois in Chicago, Illinois. Plaintiffs also filed cases in
California, Texas, Illinois, New Jersey and New York. CN is named as a defendant in the Louisiana and California actions.

In 2005, the United States District Court dismissed the proceedings with prejudice, ruling that only the legislative or executive branches of government could decide reparations issues. The U.S. Court of Appeals for
the Seventh Circuit modified that dismissal for most of the plaintiffs to a dismissal without prejudice, due to their lack of standing to bring a claim in federal court. For those plaintiffs suing as the legal representatives of the estates of
slaves, their claims were dismissed with prejudice due to the expiration of the statute of limitations. The claims of plaintiffs who alleged violations of state consumer fraud or consumer protection statutes were remanded to the District Court for
further proceedings.

|Sydney Tar Ponds Lawsuit
|------------------------

A lawsuit involving more than 350 plaintiffs was instituted on March 25, 2004 in Nova Scotia against Hawker Siddeley Canada Inc., Sydney Steel Corp., the Nova Scotia government, the Canadian government, Domtar Inc.,
and CN. The plaintiffs are seeking compensation for health problems and property losses due to soil and water contamination resulting from previous industrial activities near Sydney, Nova Scotia.

The plaintiffs seek to hold the defendants liable for battery, nuisance, trespassing, negligence, harm and injuries, family losses, as well as aggravated, punitive and additional damages. No specific amount of damages
is included in the claim.

The court action is still in the process of being certified as a class action. To date, none of the allegations contained in the claim have been proven in court.

|Paul Band Litigation
|--------------------

On February 6, 2006, the Paul Indian Band filed a lawsuit in the Court of Queens Bench of Alberta against CN and the Alberta and Canadian governments. The various claims in the lawsuit, totaling $775 million
in the aggregate, are for alleged damages and economic losses suffered as a result of an oil spill from railcars into Wabamun Lake, Alberta, bordering the Paul Band reserve lands, following the derailment of a CN train on August 3, 2005. The
plaintiffs are seeking specific damages of $500 million against CN, including $50 million in punitive damages, with the balance sought from the federal and Alberta governments.

To date, none of the allegations contained in the claim have been proven in court.

|Calvin Shaun Davey Class Action Lawsuit
|---------------------------------------

On February 17, 2006 Calvin Shaun Davey filed a statement of claim, in the Court of Queens Bench of Alberta, on behalf of himself and persons (other than the Paul Indian Band) who owned lands and premises within
a five-kilometer radius of the shores of Wabamun Lake, Alberta at the time of the spill described above. The claim seeks $750 million in general damages and $200 million in punitive damages.

On September 26, 2006, the Alberta Court of Queens Bench granted leave to discontinue the action without prejudice following an unopposed application by the Company.

See pages 24 and 25 of the MD&A for a general discussion of legal claims.

|4.7.2 | Aboriginal Claims
|----- | -----------------

CN and its predecessor companies have acquired lands throughout Canada from the Crown, including certain lands contained in aboriginal reserves. A portion of the Companys network, primarily in British Columbia,
is currently operated on these lands.

The Company believes that it possesses unrestricted and absolute title to lands acquired out of aboriginal reserves but, in recent years, some aboriginal bands have claimed to have a continuing legal interest in such
lands and they allege this interest prohibits the Company from disposing of the lands when they are no longer needed for railway purposes, except by allowing them to revert to the Crown for the benefit of aboriginals. This issue is one which will
ultimately be decided by the courts but, regardless of the outcome, there is no perceived material adverse effect as the right of the Company to continue to occupy and operate over such lands is not being called into question.

As the issues surrounding aboriginal claims are complex and involve not only private interests but fiduciary and other obligations of the Government of Canada, CN has agreed with the Government not to sell or otherwise
dispose of land which is not essential to its rail operations and which is located in, or adjacent to, an aboriginal reserve, unless each of CN and the Government are satisfied that there is no legitimate aboriginal claim with respect to such land.
In addition, CN has agreed to convey to the Government, for no consideration, any land not integral to its rail operations which may be necessary to settle legitimate aboriginal claims with respect to such land, or lands which were formerly reserve
lands and which have become non-rail assets. The Government of Canada, for its part, has agreed that it will provide the necessary compensation for settlement of legitimate aboriginal claims which would otherwise result in CN having to relinquish
land essential to its rail network, unless such claims arise out of, or are substantially based upon, willful, known, negligent or fraudulent acts or omissions of CN which adversely affected the rights or interests of aboriginal people.

|4.7.3 | Risk Factors
|----- | ------------

It is not reasonably possible to itemize all of the factors and specific events that could affect the Company and the railroad industry as a whole. The following factors (in addition to other possible factors not
listed) could affect the Companys actual results. In addition, these factors could cause such results to differ materially from those projected, forecasted, estimated, budgeted or otherwise expressed in forward-looking statements made by or on
behalf of the Company. See section 11.2 for a further discussion of risks associated with forward-looking statements.

Competition

The Company faces significant competition from
a variety of carriers, including CPR which operates the other major rail system
in Canada, serving most of the same industrial and population centers as the
Company; long distance trucking companies; and in many markets, major U.S. railroads
and other Canadian and U.S. railroads. Competition is generally based on the
quality and reliability of services provided, price, and the condition and suitability
of carriers equipment. Competition is particularly intense in eastern Canada
where an extensive highway network and population centers, located relatively
close to one another, have encouraged significant competition  from trucking
companies. In addition, much of the freight carried by the Company consists of
commodity goods that are available from other sources in competitive markets.
Factors affecting the competitive position of suppliers of these commodities,
 including exchange rates, could materially adversely affect the demand for goods
supplied by the sources served by the Company and, therefore, the Companys
volumes, revenues and profit margins.

In addition to trucking competition, and to a
greater degree than other rail carriers, the Companys
subsidiary, ICRR, is vulnerable to barge competition because its main routes
are parallel to the Mississippi River system. The use of barges for some commodities,
particularly coal and grain, often represents a lower cost mode of transportation.
Barge competition and barge rates are affected by navigational interruptions
from

---



ice, floods and droughts, which can cause widely fluctuating barge rates. The ability of ICRR to maintain its market share of the available freight has traditionally been affected by the navigational conditions on the
river.

The significant consolidation of rail systems in the United States has resulted in larger rail systems that are able to offer seamless services in larger market areas and accordingly, compete effectively with the
Company in certain markets. This requires the Company to consider transactions that would similarly enhance its own service. There can be no assurance that the Company will be able to compete effectively against current and future competitors in the
railroad industry and that further consolidation within the railroad industry will not adversely affect the Companys competitive position. No assurance can be given that competitive pressures will not lead to reduced revenues, profit margins
or both.

Environmental Matters

The Companys operations are subject to numerous federal, provincial, state, municipal and local environmental laws and regulations in Canada and the United States concerning, among other things, emissions into
the air; discharges into waters; the generation, handling, storage, transportation, treatment and disposal of waste, hazardous substances and other materials; decommissioning of underground and aboveground storage tanks; and soil and groundwater
contamination.  A risk of environmental liability is inherent in railroad and related transportation operations; real estate ownership, operation or control; and other commercial activities of the Company with respect to both current and past
operations. As a result, the Company incurs significant compliance and capital costs, on an ongoing basis, associated with environmental regulatory compliance and clean-up requirements in its railroad operations and relating to its past and present
ownership, operation or control of real property.

While the Company believes that it has identified the costs likely to be incurred in the next several years, based on known information, for environmental matters, the Companys ongoing efforts to identify
potential environmental concerns that may be associated with its properties may lead to future environmental investigations, which may result in the identification of additional environmental costs and liabilities.

In railroad and related transportation operations, it is possible that derailments, explosions or other accidents may occur that could cause harm to human health or to the environment. In
addition, the Company is also exposed to liability risk, faced by the railroad industry generally, in connection with the transportation of toxic-by-inhalation hazardous materials such as chlorine and anhydrous ammonia, commodities that are
essential to the public health and welfare and that, as a common carrier, the Company has a duty to transport. As a result, the Company may incur costs in the future, which may be material, to address any such harm, including costs relating to the
performance of clean-ups, natural resource damages and compensatory or punitive damages relating to harm to individuals or property.

The ultimate cost of known contaminated sites cannot be definitively established, and the estimated environmental liability for any given site may vary depending on the nature and extent of the contamination, the
available clean-up techniques, the Companys share of the costs and evolving regulatory standards governing environmental liability. Also, additional contaminated sites yet unknown may be discovered or future operations may result in accidental
releases. For these reasons, there can be no assurance that material liabilities or costs related to environmental matters will not be incurred in the future, or will not have a material adverse effect on the Companys financial position or
results of operations in a particular quarter or fiscal year, or that the Companys liquidity will not be adversely impacted by such environmental liabilities or costs.

21

---



Personal Injury and Other Claims

In the normal course of its operations, the Company becomes involved in various legal actions, including claims relating to personal injuries, occupational disease and damage to property. The Company maintains
provisions for such items, which it considers to be adequate for all of its outstanding or pending claims. The final outcome with respect to actions outstanding or pending at December 31, 2006, or with respect to future claims, cannot be predicted
with certainty, and therefore there can be no assurance that their resolution will not have a material adverse effect on the Companys financial position or results of operations in a particular quarter or fiscal year.

Labor Negotiations

|*Canadian
    Workforce*
|------------------------

As at December 31, 2006, CN employed a total of 15,232 employees in Canada, of which 12,183 were unionized employees.

As of February 2007, the Company had in place labor agreements covering its entire Canadian unionized workforce. In September 2006, the Company began bargaining with the two unions whose agreements were to expire on
December 31, 2006; namely the United Transportation Union (UTU), which represents conductors and yard coordinators, and the National Automobile Aerospace Transportation and General Workers Union of Canada (Canadian Auto Workers or CAW), which
represents clerical and intermodal employees in one bargaining unit, shopcraft employees in a separate bargaining unit, as well as owner-operator truck drivers in a third bargaining unit. On January 14, 2007, the Company and the CAW reached
tentative agreements covering all three bargaining units. The CAW completed its ratification process on January 29, 2007, and as a result, the collective agreements have been renewed for a four-year period ending December 31, 2010.

With respect to the UTU negotiations, on November
20, 2006, the Minister of Labour (Canada) appointed two conciliation officers
to assist with negotiations pursuant to a request from the UTU, which CN had
opposed as  being premature. Following a conciliation process and the completion
of required legislated processes, the Union claimed it was in a legal strike
position, and the Company would have been legally permitted to lockout the members
of the UTU bargaining unit or promulgate work rule changes unilaterally on February
9, 2007. On February 6, 2007, the UTU served a 72-hour advance strike
notice to the Company and they commenced work stoppage on February 10, 2007.
The Company is seeking to have the UTU work stoppage declared illegal. The UTU
had also advised the Company that because the UTU-represented employees of the
former BC Rail were legally members of its CN bargaining unit, it intended to
bargain terms and conditions for those employees in conciliation along with its
demands covering all its other members at CN. The Company intends to maintain
its operations notwithstanding the work stoppage by the UTU-represented employees.
Although there can be no assurance to such effect, the Company remains optimistic
that a resolution can be reached quickly and that its operations will return
to normal with minimal adverse effects on the Companys
financial position or results of operations. The Company also has an agreement
with the UTU for its Northern Quebec line, which is set to expire on December
15, 2007.

Following the acquisition of BC Rail, the Company reached implementing agreements in December 2004 for former BC Rail employees with the Council of Trade Unions and its members, representing all unions, regarding the
integration of the various collective agreements. In March 2005, under Section 18 of the Canada Labour Code, the Company had filed a request with the Canada Industrial Relations Board (CIRB) to amend the current bargaining agent certificates at BC
Rail to correspond with those agents representing the same employee groups at CN. On March 9, 2006, the CIRB issued its final decision and granted the Companys request to integrate the former BC Rail

22

---



employees into CNs bargaining unit structures. Subsequently, the CAW union requested that the CIRB reconsider its decision. On April 20, 2006, the CIRB rejected the CAWs application and advised that its
decision was final.

In 2007, CN will begin bargaining with two other national unions whose agreements expire December 31, 2007. These agreements will remain in effect until bargaining and legal processes have been concluded.

There can be no assurance that the Company will be able to renew and have ratified its collective agreements without any strikes or lockouts or that the resolution of these collective bargaining negotiations will not
have a material adverse effect on the Companys financial position or results of operations.

|U.S. Workforce
|--------------

As at December 31, 2006, CN employed a total of 6,579 employees in the United States, of which 5,732 were unionized employees.

As of February 2007, the Company had in place
agreements with bargaining units representing the entire unionized workforce
at GTW; Duluth, Winnipeg and Pacific (DWP); ICRR; CCP Holdings, Inc. (CCP);
DMIR; BLE;
and PCD; and 98% of the unionized workforce
at WC.  Agreements in place have
various moratorium provisions, ranging from 2004 to 2011, which preserve the
status quo in respect of given areas during the terms of such moratoriums. Several
of these agreements are currently under  renegotiation.

The general approach to labor negotiations by U.S. Class I railroads is to bargain on a collective national basis. GTW, DWP, ICRR, CCP, WC, DMIR, BLE and PCD have bargained on a local basis rather than holding
national, industry-wide negotiations because they believe it results in agreements that better address both the employees concerns and preferences, and the railways actual operating environment.  However, local negotiations may not
generate federal intervention in a strike or lockout situation, since a dispute may be localized.  The Company believes the potential mutual benefits of local bargaining outweigh the risks.

Negotiations are ongoing with the bargaining units with which the Company does not have agreements or settlements. Until new agreements are reached or the processes of the Railway Labor Act have been exhausted, the
terms and conditions of existing agreements generally continue to apply.  On July 19, 2006, one of the unions representing 250 GTW employees took a one-day strike action during the mediation process.  However, a U.S. District Court subsequently
determined that the strike action was improper and enjoined employees from further action. The employees returned to work and the Company continues to be in mediation with that union. There can be no assurance that there will not be any work action
by any of the bargaining units with which the Company is currently in negotiations or that the resolution of these negotiations will not have a material adverse effect on the Companys financial position or results of operations.

Regulation

The Companys rail operations in Canada are subject to (i) regulation as to rate setting, level of service and network rationalization by the Canadian Transportation Agency (the Agency) under the Canada
Transportation Act (the CTA), and (ii) safety regulation by the federal Minister of Transport under the Railway Safety Act and certain other statutes. The Companys U.S. rail operations are subject to (i) economic regulation by the Surface
Transportation Board (STB) and (ii) safety regulation by the Federal Railroad Administration (FRA).  As such, various Company business transactions must gain prior regulatory approval, with attendant risks and uncertainties, and the Company is
subject

23

---



to government oversight with respect to rate and service issues. In particular, the STB completed a proceeding on January 26, 2007 in which it reviewed the practice of rail carriers, including the Company and the
majority of other large railroads operating within the U.S., of assessing a fuel surcharge computed as a percentage of the base rate for service.  Following its review, the STB directed carriers to change that practice and adjust their fuel
surcharge programs within 90 days on a basis more closely related to the amount of fuel consumed on individual movements. The Company is evaluating the impact of the STBs decision. The Company is also subject to a variety of health, safety,
security, labor, environmental and other regulations, all of which can affect its competitive position and profitability.

The Companys ownership of the former Great Lakes Transportation vessels is subject to regulation by the U.S. Coast Guard and the Department of Transportation, Maritime Administration, which regulate the ownership
and operation of vessels operating on the Great Lakes and in U.S. coastal waters. While recent Congressional legislation and Coast Guard rulemakings have not adversely affected CNs ownership of these vessels, no assurance can be given that any
future legislative or regulatory initiatives by the U.S. federal government will not materially adversely affect the Companys operations or its competitive and financial position.

With respect to safety, rail safety regulation in Canada is the responsibility of Transport Canada, which administers the Canadian Railway Safety Act, as well as the rail portions of other safety-related statutes. In
the U.S., rail safety regulation is the responsibility of the FRA, which administers the Federal Rail Safety Act, as well as the rail portions of other safety statutes. In addition, safety matters related to security are overseen by the
Transportation Security Administration (TSA), which is part of the U.S. Department of Homeland Security and the Pipeline and Hazardous Materials Safety Administration (PHMSA), which, like the FRA, is part of the U.S. Department of
Transportation.

The federal government carries out a review of Canadian transportation legislation periodically. The latest review resulted in a report to the Minister of Transport, released to the public on July 18, 2001, which
contains numerous recommendations for legislative changes affecting all modes of transportation, including rail. On February 25, 2003, the Canadian Minister of Transport released the policy document Straight Ahead - A Vision for Transportation in
Canada.  On March 24, 2005, the Minister of Transport tabled Bill C-44 entitled An Act to Amend the Canada Transportation Act and the Railway Safety Act, to enact the VIA Rail Canada Act and to make consequential amendments to other Acts. Bill C-44
was terminated when Parliament was dissolved on November 29, 2005 and has since been replaced by two separate pieces of legislation: Bill C-3 entitled International Bridges and Tunnels Act, tabled on April 24, 2006 and Bill C-11 entitled
Transportation Amendment Act, tabled on May 4, 2006, relating to passenger service providers, noise, mergers and other issues. Also, the federal government is currently engaged in a consultative process relating to shipper-railway relationships.  On
December 14, 2006, the federal government announced a full review of the Railway Safety Act. Members of the panel to conduct the review are expected to be appointed in early 2007 and are expected to submit their report in the fall of 2007. No
assurance can be given that any future legislative action by the federal government or other future government initiatives will not materially adversely affect the Company's financial position or results of operations.

The U.S. Congress has had under consideration for several years various pieces of legislation that would increase federal economic regulation of the railroad industry, and additional legislation was introduced in 2006.
In addition, the STB is authorized by statute to commence regulatory proceedings if it deems them to be appropriate.  No assurance can be given that any future regulatory initiatives by the U.S. federal government will not materially adversely
affect the Companys operations, or its competitive and financial position.

The Company is subject to statutory and regulatory directives in the United States addressing homeland security concerns. These include border security arrangements, pursuant to an agreement the Company and CP entered
into with U.S. Customs and Border Protection (CBP) and the Canada Border Services Agency (CBSA).  These requirements include advance electronic transmission of cargo information for U.S.-bound traffic and cargo screening (including gamma ray and
radiation screening), as well as U.S. government-imposed restrictions on the transportation into the United States of certain commodities. These also include participation in CBPs Customs-

24

---



Trade Partnernship Against Terrorism (C-TPAT) program and designation as a low-risk carrier under CBSAs Customs Self-Assessment (CSA) program.  In the fourth quarter of 2003, the CBP issued regulations to extend
advance notification requirements to all modes of transportation and the U.S. Food and Drug Administration promulgated interim final rules requiring advance notification by all modes for certain food imports into the United States. CBSA is also
working on implementation of advance notification requirements for Canadian-bound traffic. Recently, the U.S. Department of Agriculture (USDA) issued a proposed interim rule, which would remove the current exemption from inspection for imported
fruits and vegetables grown in Canada and the exemptions for all transport modes from the agricultural quarantine and inspection (AQI) user fee for traffic entering the U.S. from Canada. The rule was originally scheduled to take effect on November
24, 2006, but the USDA deferred implementation for surface modes until March 1, 2007.

The Company has also worked with the Association of American Railroads to develop and put in place an extensive industry-wide security plan to address terrorism and security-driven efforts by state and local
governments seeking to restrict the routings of certain hazardous materials. If such state and local routing restrictions were to go into force, they would be likely to add to security concerns by foreclosing the Companys most optimal and
secure transportation routes, leading to increased yard handling, longer hauls, and the transfer of traffic to lines less suitable for moving hazardous materials, while also infringing upon the exclusive and uniform federal oversight over railroad
security matters. In addition to recommended security action items for the rail transportation of toxic inhalation hazard (TIH) materials jointly announced by the TSA and the FRA on June 23, 2006 and November 21, 2006, the TSA and the PHMSA also
separately issued, on December 21, 2006, related notices of proposed rulemakings.  Among other things, the TSAs regulations would require rail carriers operating within the U.S. to provide upon request, within one hour, location and shipping
information on cars on their networks containing TIH materials and certain radioactive or explosive materials, and ensure the secure, attended transfer of all such cars to and from shippers, receivers and other carriers. The PHMSAs regulations
would require carriers to report annually the volume and route-specific data for cars containing these commodities; conduct a safety and security risk analysis for each used route; identify a commercially practicable alternative route for each used
route; and select for use the practical route posing the least safety and security risk.

While the Company will continue to work closely with the CBSA, CBP, and other Canadian and U.S. agencies, as described above, no assurance can be given that these and future decisions by the U.S., Canadian, provincial,
state, or local governments on homeland security matters, legislation on security matters enacted by the U.S. Congress, or joint decisions by the industry in response to threats to the North American rail network, will not materially adversely
affect the Companys operations, or its competitive and financial position.

Business Prospects and Other Risks

In any given year, the Company, like other railroads, is susceptible to changes in the economic conditions of the industries and geographic areas that produce and consume the freight it transports or the supplies it
requires to operate. In addition, many of the goods and commodities carried by the Company experience cyclicality in demand. Many of the bulk commodities the Company transports move offshore and are affected more by global rather than North American
economic conditions.  The Companys results of operations can be expected to reflect these conditions because of the significant fixed costs inherent in railroad operations.

Global as well as North American trade conditions, including trade barriers on certain commodities, may interfere with the free circulation of goods across Canada and the United States.

As part of the Security and Prosperity Partnership entered into in 2005 by the Presidents of the United States and Mexico and the Prime Minister of Canada, as a trilateral effort to increase security and enhance
prosperity among Canada, the U.S. and Mexico, a North American Competitiveness Council has been created.  The Council is intended to engage the private sector as partners with the governments of the three countries in finding solutions to

25

---



North American trade and security issues in the context of the Security and Prosperity Partnership.  The Prime Minister has designated the Companys President & Chief Executive Officer as a member of the
Council, and CN will be active in the Councils activities.

The Company, like other railroads, is susceptible to the volatility of fuel prices due to changes in the economy or supply disruptions. Rising fuel prices could materially adversely affect the Companys expenses.
As such, CN has implemented a fuel surcharge program to help mitigate the impact of rising fuel prices. No assurance can be given that continued increases in fuel prices or supply disruptions will not materially adversely affect the Companys
operations or its financial position.

Overall return in the capital markets, and the level of interest rates, affect the funded status of the Company's pension plans as well as the Company's results of operations. Adverse changes with respect to pension
plan returns and the level of interest rates from the date of the last actuarial valuation may increase future pension contributions and could have a material adverse effect on the Companys results of operations. The funding requirements, as
well as the impact on the results of operations, will be determined following the completion of future actuarial valuations.

Potential terrorist actions can have a direct or indirect impact on the transportation infrastructure, including railway infrastructure in North America, and interfere with the free flow of goods. International
conflicts can also have an impact on the Companys markets.

The Company conducts its business in both Canada and the U.S. and as a result, is affected by currency fluctuations. Based on the Companys current operations, the estimated annual impact on net income of a
year-over-year one-cent change in the Canadian dollar relative to the U.S. dollar is approximately $11 million. Changes in the exchange rate between the Canadian dollar and other currencies (including the U.S. dollar) make the goods transported
by the Company more or less competitive in the world marketplace and thereby further affect the Companys revenues and expenses.

Should a significant economic slowdown or recession occur in North America or other key markets, or should major industrial restructuring take place, the volume of rail shipments carried by the Company may be adversely
affected.

In addition to the inherent risks of the business cycle, the Companys operations are occasionally susceptible to severe weather conditions, which can disrupt operations and service for the railroad as well as for
the Companys customers. In recent years, severe drought conditions in western Canada, for instance, significantly reduced bulk commodity revenues, principally grain.

|ITEM 5 | DIVIDENDS
|------ | ---------

The Company has declared dividends in line with
its overall financial performance and cash flow generation. The Board of Directors
makes decisions on dividend payout on a quarterly basis. Consistent with this
practice,  the quarterly rate of $0.0975 per share, starting with the first
quarter of 2004, was increased to $0.125 per share, starting with the first
quarter of 2005; the quarterly dividend was next increased to $0.1625 per
share, starting with  the first quarter of 2006 and to $0.21 per share, starting
with the first quarter of 2007. There can be no assurance as to the amount or
timing of such dividends in the future.

|ITEM 6 | DESCRIPTION OF CAPITAL STRUCTURE

|       |                                      
|6.1    | GENERALDESCRIPTION OFCAPITALSTRUCTURE

The authorized share capital of CN consists of
an unlimited number of common shares, an unlimited number of Class A Preferred
Shares issuable in series and an unlimited number of Class B Preferred Shares
issuable in series, all without par value. As at February 12, 2007, the issued
and outstanding share capital consisted of 511,456,177 common shares.

26

---



Common Shares

The common shares carry and are subject to the following rights, privileges, restrictions and conditions described below:

Voting:Each common share entitles its holder to receive notice of and to attend all general and special meetings of shareholders of CN, other than meetings at which only
the holders of a particular class or series of shares are entitled to vote, and each such common share entitles its holder to one vote.

Dividends:The holders of common shares are, at the discretion of the Directors, entitled to receive, out of any amounts properly applicable to the payment of dividend, and
after the payment of any dividends payable on any Preferred Shares, any dividends declared and payable by CN on the common shares.

Dissolution: The holders of common shares shall be entitled to share equally in any distribution of the assets of CN upon the liquidation, dissolution or winding-up of CN or
other distribution of its assets among its shareholders. Such participation is subject to the rights, privileges, restrictions and conditions attaching to any issued and outstanding Preferred Shares or shares of any other class ranking prior to the
common shares.

Preferred Shares

The Class A Preferred Shares and the Class B Preferred Shares are issuable in series and, subject to CNs Articles, the Board of Directors is authorized to fix, before issuance, the designation, rights,
privileges, restrictions and conditions attaching to the shares of each series. The holders of Class A Preferred Shares or Class B Preferred Shares shall not be entitled to vote at meetings of shareholders otherwise than as provided by law, and
holders of Class A or Class B Preferred Shares shall not be entitled to vote separately as a class except as provided by law.

There are neither any Class A Preferred Shares nor any Class B Preferred Shares currently issued and outstanding.

|6.2 | SHARE OWNERSHIP
            CONSTRAINTS
|--- | ---------------------------------------

CNs Articles provide that where the total number of voting shares held, beneficially owned, or controlled, directly or indirectly, by any one person together with his or her associates exceeds 15%, no person
  shall exercise the voting rights attached to the voting shares held, beneficially owned or controlled, directly or indirectly, by such person or his or her associates. Furthermore, all dividends attributable to the percentage of voting shares held
  by such persons in excess of 15% shall be forfeited, including any cumulative dividend. CNs Articles confer on the Board of Directors all powers necessary to give effect to the ownership restrictions, including the ability to pay dividends or
  to make other distributions which would otherwise be prohibited if the event giving rise to the prohibition was inadvertent or of a technical nature or it would otherwise be inequitable not to pay the dividends or make the distribution. CNs
  Articles provide that the Board of Directors may adopt by-laws concerning the administration of the constrained share provisions described above, including by-laws requiring a shareholder to furnish a declaration indicating whether he or she is the
  beneficial owner of the shares and whether he or she is an associate of any other shareholder. In addition, CN is also authorized to refuse to recognize the ownership rights that would otherwise be attached to any voting shares held, beneficially
  owned or controlled, directly or indirectly, contrary to the share ownership constraint. Finally, CN has the right, for the purpose of enforcing any constraint imposed pursuant to its Articles, to sell, as if it were the owner thereof, any voting
  shares that are owned or that the Directors determine may be owned, by any person or persons contrary to such share ownership constraint.

|6.3 | RATINGS OF
            DEBT SECURITIES
|--- | --------------------------------------

Various classes of CNs outstanding securities have been rated by several rating organizations as described in detail below, as at February 12, 2007.

Dominion Bond Rating Service Limited (DBRS)

| | 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 AA rated securities. While A is
        a respectable rating, entities in this category
        are considered to be more susceptible to adverse economic conditions
        and have greater cyclical tendencies than higher-rated securities. This rating falls
        within the third highest of DBRSs ten long-term debt
        rating categories which range from AAA to D.
        Reference to low denotes a standing in the lower end

| | Commercial paper rated R-1
        (low) is of satisfactory credit quality. The overall strength and outlook
        for key liquidity, debt, and profitability
        ratios is not normally as favourable as with higher rating categories,
        but these considerations 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. This rating
        falls within the third highest
        of DBRSs ten short-term debt rating categories which range from R-1
        (high) to
D.                     

Moodys Investors Service (Moodys)

| | Long-term debt obligations
        rated A are considered upper-medium grade and are subject to low credit
        risk. This rating falls within
        the third highest of Moodys nine generic long-term obligation rating
        categories which range from Aaa to C.
        The modifier 3 indicates a ranking in the lower end of that
    generic rating category.

Standard & Poors (S&P)

| | Long-term debt obligations
        rated A are somewhat more susceptible to the adverse effects of changes
        in circumstances and economic conditions
        than obligations in higher rated categories. The obligors capacity
        to meet its financial commitment
        on the obligations is, however, still strong. This rating falls within
        the third highest of S&Ps

| | Commercial paper rated A-2
        is somewhat more susceptible to the adverse effects of changes in circumstances
        and economic conditions than obligations in higher rating categories.
        However, the obligors capacity
        to meet its financial commitment on the obligation is satisfactory. This
        rating falls within the second highest
        in S&Ps six short-term credit rating categories which range
    form A-1 to D.

      Audit Committee approves all audit and audit-related services, audit engagement
      fees and terms and all non-audit engagements with the independent auditor.
      The Audit Committee pre-approved all the services performed by CNs
      independent auditors for audit-related and non-audit related services for
      the year ended December 31, 2006 that were required to be pre-approved.


A discussion of the nature of the services under each category is described below.

Audit fees

Consists of fees incurred for professional services
rendered by the auditors in relation to the audit of the Companys
consolidated annual financial statements and those of its subsidiaries, and for
2006 only, the first audit relating to the Companys internal control over
financial reporting.

Audit-related fees

Audit-related fees were incurred for professional
services rendered by the auditors in relation to the audit of the financial statements
for the Companys pension plans, and for  attestation services in connection
with reports required by statute or regulation and due diligence and other services,
including comfort letters, in connection with the issuance of securities.

Tax fees

Consists of fees incurred for consultations on cross-border tax implications for employees and tax compliance.

Other fees

In 2005, the entire amounts were incurred for consultations with respect to the U.S. Sarbanes-Oxley Act of 2002, Section 404 Report on Internal Controls.

The mandate of the Audit Committee, attached as
Schedule A to this AIF, provides that the Audit Committee determines which non-audit
services the external auditors are prohibited from providing, approves audit
services  and pre-approves permitted non-audit services to be provided by the
external auditors. CNs Audit Committee and the Board of Directors have
adopted resolutions prohibiting the Company from engaging KPMG LLP to provide
certain non-audit services  to the Company and its subsidiaries, including bookkeeping
or other services related to the accounting records or financial statements,
financial information systems design and implementation, appraisal or valuation
services, fairness opinions, or  contribution in-kind reports, actuarial services,
internal audit outsourcing services, management functions or human resources
functions, broker or dealer, investment adviser, or investment

banking services and legal services and expert services unrelated to the audit. Pursuant to such resolutions, the Company may engage KPMG LLP to provide non-audit services, including tax services, other than the
prohibited services listed above, but only if the services have specifically been pre-approved by the Audit Committee.

|11.2 | FACTORS FOR
            FORWARD-LOOKING INFORMATION
|---- | ---------------------------------------------------

Canadian and U.S. securities laws provide a safe harbor for forward-looking statements to encourage companies to provide prospective information, so long as such information is identified as
  forward-looking and is accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially

from those discussed in the statement. Except for historical information, certain statements contained in this annual information form and annual report filed with Canadian securities authorities and filed on Form 40-F
with the U.S. Securities and Exchange Commission may be forward-looking statements within the meaning of such Canadian and U.S. securities laws. In addition, the Company and its representatives from time to time participate in speeches,
meetings and calls with market analysts, conferences with investors and potential investors in the Companys securities, and other meetings and conferences. Some of the information presented in such speeches, calls, meetings and conferences may
be forward-looking within the meaning of such Canadian and U.S. securities laws. Implicit in these statements, particularly in respect of growth opportunities, is the assumption that the positive economic trends in North America and Asia will
continue. This assumption, although considered reasonable by the Company at the time of preparation, may not materialize. Such forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and
other factors which may cause the outlook, the actual results or performance of the Company or the rail industry to be materially different from any future results or performance implied by such statements. Such factors include the specific risks
set forth below as well as other risks detailed from time to time in reports filed by the Company with securities regulators in Canada and the United States.

In order to take advantage of such safe harbor provisions, the Company identified the important factors set forth below that could affect the Companys actual results and cause such results to differ
materially from those projected, forecasted, estimated, budgeted or otherwise expressed by the Company in forward-looking statements made by or on behalf of the Company. Reference is made to section 4.7.3 for additional discussion of such
factors.

|(1)  | Significant competition may lead to reduced volumes and revenues and narrower profit margins.

|    
|(3)  | The outcome of outstanding or pending legal actions as well as future claims cannot be predicted with certainty.                                                                                                                                             
|    
|(4)  | The outcome of current and future labor negotiations of certain of the Companys labor agreements is uncertain.                                                                                                                                              
|    
|(5)  | New legislative, administrative or judicial actions that constrain market forces may have a material adverse effect on the Companys competitive position and profitability.

|    
|(7)  | Adverse changes with respect to pension plan returns and the level of interest rates from the date of the last actuarial valuation may increase future pension contributions and could have a material adverse effect on
the Companys results of operations.
|    
|(8)  | Substantial ongoing capital expenditures may require the Company to seek additional financing.                                                                                                                                                               
|    
|(9)  | Changes in the exchange rate between the Canadian dollar and other currencies may adversely affect the Companys results of operations.                                                                                                                      
|    
|(10) | Adverse economic conditions in the industries and geographic areas that produce and consume the freight the Company transports or the supplies it requires to operate may affect the Companys results of
operations.                                        
|    
|(11) | International conflicts and potential terrorist actions may impact the Companys results of operations.

|  
|   |                                                  | ensuring that processes are in place to annually evaluate the performance of the Audit Committee.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              

In addition to the above responsibilities, the Audit Committee may discharge the responsibilities of the Finance Committee if no meeting of the Finance Committee is scheduled to be held in the immediate
future.

Because of the Audit Committees demanding
role and responsibilities, the Board chair, together with the Corporate Governance
and Nominating Committee chair, reviews any invitation to Audit Committee members
to  join the audit committee of another entity. Where a member of the Audit Committee
simultaneously serves on the audit committee of more than three public companies,
including CN, the Board determines whether such simultaneous service impairs
the  ability of such member to effectively serve on the Audit Committee and either
requires a correction to the situation or discloses in CNs Information
Circular that there is no such impairment.

As appropriate, the Audit Committee may retain
independent advisors to help it carry out its responsibilities, including fixing
such advisors fees and retention terms, subject to advising the Board chair;
the  Committee makes arrangements for the appropriate funding for payment of
the external auditors and any advisors retained by it. The Board also provides
appropriate funding for all administrative expenses necessary or appropriate
to allow the Audit  Committee to carry out its duties.

The Audit Committee has direct communication channels with the internal and external auditors to discuss and review specific issues, as appropriate. In addition, each must meet separately with the Audit Committee,
without management, twice a year, and more frequently as required; the Audit Committee must also meet separately with management twice a year, and more frequently as required.

The Audit Committee shall report to the Board
regularly on its deliberations and annually on the adequacy of its mandate.

Nothing contained in the above mandate is intended
to assign to the Audit Committee the Boards responsibility to ensure CNs
compliance with applicable laws or regulations or to expand applicable standards
 of liability under statutory or regulatory requirements for the Directors or
the members of the Audit Committee. Even though the Audit Committee has a specific
mandate and its members may have financial experience and expertise, it is not
the duty  of the Audit Committee to plan or conduct audits, or to determine that
the Companys financial statements are complete and accurate and are in
accordance with generally accepted accounting principles. Such matters are the
responsibility of  management, the internal auditors and the external auditors.

Members of the Audit Committee are entitled to rely, absent knowledge to the contrary, on (i) the integrity of the persons and organizations from whom they receive information, (ii) the accuracy and completeness of the
information provided, and (iii) representations made by management as to the non-audit services provided to the Company by the external auditors.

The Audit Committees oversight responsibilities are not established to provide an independent basis to determine that (i) management has maintained appropriate accounting and financial reporting principles or
appropriate internal controls and procedures, or (ii) the Companys financial statements have been prepared and, if applicable, audited in accordance with generally accepted accounting principles or generally accepted auditing
standards.
