ITEM 3  GENERAL DEVELOPMENT OF THE BUSINESS

---

Corporate Overview

Prior to July 1991, the Government of Canada owned 100 per cent of the issued and outstanding common shares of the Corporation. The Corporation completed
its initial public offering of common shares in July 1991. The Government of Canada's interest in the outstanding shares of the Corporation has been further reduced through a series of treasury
and government secondary common share offerings. As of December 31, 2002, the Government of Canada's interest in the outstanding shares of the Corporation was 18.74 per cent. The
following is a recent history of major Company events.

In
1998, Petro-Canada began development of the Terra Nova project. We sold several non-core properties in Western Canada for gross proceeds of approximately
$230 million, sold ICG Propane Inc. for gross proceeds of $177 million and sold our 50 per cent interest in Petro-Canada Centre, our head office complex
in Calgary, Alberta for gross proceeds of $200 million.

In
1999, to enhance opportunities for future profitable growth in Canadian natural gas and Grand Banks oil production, we acquired acreage in the Mackenzie Delta, located in the
Northwest Territories, the Flemish Pass, located offshore Newfoundland, and the Scotian Slope, located offshore Nova Scotia. Construction continued on the Terra Nova project.

In
2000, to sharpen the focus on our core businesses, we sold our natural gas liquids business, non-core oil and gas properties and other assets for proceeds totalling
$722 million. Our ownership interests in two Grand Banks properties, Terra Nova and White Rose, were increased through a property swap. Development of Terra Nova continued with delivery of the
floating production, storage and offloading (FPSO) vessel. Construction commenced on Petro-Canada's firstin situoil sands commercial
development at MacKay River in northeastern Alberta.

In
2001, Petro-Canada commissioned the offshore facilities for the Terra Nova oil field, allowing production start-up to occur in January 2002. In Oil
Sands, we participated in the launch of Phase 3 of the Syncrude expansion, advanced the construction of our MacKay River bitumen production facility and articulated a growth strategy linking
staged development ofin-situbitumen production with conversion of our Edmonton refinery. In our North American Natural Gas business we
drilled the first well in the Mackenzie Delta in a decade and expanded our exploration focus with the acquisition of exploratory acreage in Alaska. Internationally, we expanded our
presence in North Africa with the acquisition of an interest in

the En Naga block in Libya's Sirte basin for $121 million. In the Downstream, improved plant reliability, a strong performance from Lubricants, and the continued growth in non-petroleum
revenue produced strong results in a weaker business environment. We repurchased approximately 13 million common shares at a cost of $496 million during the term of a
12-month Normal Course Issuer Bid that expired on October 31, 2001, and we repaid $475 million of long-term debt.

In
2002, Petro-Canada acquired most of the upstream oil and gas businesses of Veba Oil & Gas GmbH for $2 234 million, establishing
International as a new core business. In Canada, strong operating performance at Hibernia combined with an exceptional start-up year at Terra Nova to raise Petro-Canada's share
of East Coast crude oil production to 71 900 barrels of oil per day (b/d). Development commenced at White Rose, which will be the third producing oil field on the Grand Banks. The
MacKay River bitumen production facility was completed on schedule and on budget and started production in November 2002. Regulatory applications for the 80 000 b/d Meadow
Creekin situproject and Edmonton refinery feed conversion advanced under government review. A natural gas discovery at the Tuk
M-18 well in the Mackenzie Delta tested at restricted rates up to 30 million cubic feet per day (mmcf/d). Petro-Canada won the 2002 Convenience
Store Chain of the Year Award from leading U.S. trade publication Convenience Store Decisions. We repaid $465 million of debt in 2002, followed by an additional repayment of
$100 million in January 2003.

Significant Acquisitions and Dispositions in 2002

International

On
May 2, 2002, Petro-Canada acquired the shares of companies holding the majority of the international upstream oil and gas businesses of Veba Oil & Gas GmbH (Veba)
and on December 10, 2002, Petro-Canada acquired from Veba a 50 per cent
working interest in the La Ceiba block in western Venezuela which had been subject to rights of first refusal. The total acquisition cost, consisting of a cash consideration and acquisition
costs, totalled $2 234 million. Rights of first refusal were exercised by third parties with respect to assets in Norway and Egypt. A remaining right of first refusal concerning
Veba's Cerro Negro heavy oil operations in Venezuela remained pending resolution at year-end. The Veba acquisition established Petro-Canada's international operations as a
fifth core business with operations focused on three major hydrocarbon regions: Northwest Europe, North Africa/Near East and Northern Latin America. (Additional information regarding this acquisition
can be found at Note 3 of the Notes to Consolidated Financial Statements and in Management's Discussion & Analysis, in the Financing Activities section and under International in the
Upstream Review and Outlook section.)

ITEM 4  DESCRIPTION OF THE BUSINESS

---

Business of Petro-Canada

The following business description should be read in conjunction with Petro-Canada's Management's Discussion and Analysis ("MD&A") (See
"Item 6  Management's Discussion and Analysis").

Petro-Canada
is an integrated oil and gas company with a portfolio of businesses spanning both the upstream and downstream of the industry. In the Upstream,
Petro-Canada explores for, develops, produces and markets crude oil and natural gas. Our Downstream business refines crude oil and other feedstocks and markets and distributes petroleum
products and related goods and services. For reporting purposes, Petro-Canada operates in three business segments: Upstream Canada, which includes three of the Company's core businesses,
namely North American Natural Gas, Oil Sands and East Coast Oil; Upstream International; and Downstream.

The
chart below outlines the various businesses of Petro-Canada as at December 31, 2002.

Upstream Canada

Petro-Canada is a major participant in Canada's upstream oil and gas industry and is active in the exploration for and development of oil and
natural gas reserves in Canada and exploration for natural gas in Alaska. On the Grand Banks, offshore Newfoundland, Petro-Canada has a 20 per cent interest in the Hibernia
oil field, a 34 per cent share of production from the Terra Nova oil field and a 27.5 per cent interest in the White Rose oil field, which is currently under development.
Our East Coast growth strategy envisions extending plateau production through field extensions at Hibernia and Terra Nova. The Company has major oil sands interests including its 12 per cent
participation in the Syncrude joint venture and 100 per cent ownership of the recently completed MacKay Riverin situdevelopment, both
located in northeastern Alberta. A secondin situdevelopment is planned at Meadow Creek (Petro-Canada working
interest  75 per cent). Application for the Meadow Creek development is under regulatory review. Start-up at Meadow Creek will be
coordinated with the first phase of a planned conversion at the Edmonton refinery to allow the refinery to replace its existing feedstock with bitumen. Petro-Canada is one of the largest
producers of natural gas in Western Canada and, for longer-term growth, we are pursuing exploration opportunities in such high potential areas as the Mackenzie Delta, the Scotian Slope and
Alaska.

The
following table shows our estimates of Petro-Canada's Canadian proved crude oil reserves (including synthetic crude oil and bitumen) before royalties and average daily
production of crude oil before royalties by major fields.

East Coast Oil

Petro-Canada
has crude oil and natural gas interests off Canada's East Coast located principally on the Grand Banks area east of Newfoundland. To date, our focus has been directed,
primarily, towards our major Grand Banks oil field developments, Hibernia, Terra Nova and White Rose. We expect that the experience, technology and infrastructure developed for these projects will
form the basis for potential development of other discoveries on the Grand Banks.

Hibernia

The
Hibernia oil field lies 315 kilometres east-southeast of St. John's, Newfoundland in 80 metres of water. Petro-Canada has a 20 per cent interest in the field.
Petro-Canada's share of Hibernia production averaged 36 100 b/d in 2002, compared to 29 700 b/d in 2001. The Hibernia field is estimated to
have a remaining production life of 18 to 20 years.

At
December 31, 2002, there were 14 producing oil wells, seven water injection wells and five gas injection wells in operation in the Hibernia formation.
As well, the Ben Nevis Avalon formation had three wells capable of production and two water injection wells in operation. Hibernia crude oil is transported by shuttle tanker to a
transshipment terminal on the Avalon Peninsula at Whiffen Head, Newfoundland or directly to market, if tanker schedules permit. Crude oil delivered to the transshipment facility is transferred to
storage tanks and loaded onto tankers for transport to market. Petro-Canada has a 14 per cent ownership interest in the transshipment facility.

The
royalty regime for the Hibernia project has three tiers: gross royalty, net royalty and supplementary royalty. An initial gross royalty of one per cent of gross field revenue
increased to two per cent on September 1, 1999, to three per cent on March 1, 2001 and to four per cent on June 1, 2002. The one per cent increments
occur at the earlier of 18-month intervals or the attainment of specified cumulative production amounts. The gross royalty will continue to increase by increments of one per cent to
a maximum of five per cent of gross field revenue. The gross royalty is indexed to crude oil prices under certain conditions. Upon achieving payout, including a specified return allowance, the
net royalty payable becomes the greater of

8    Petro-Canada Annual Information Form

---

30 per cent of net revenue or five per cent of gross revenue. After a further level of payout is reached, which includes an additional return allowance, a supplementary royalty
of 12.5 per cent of net revenue also becomes payable. Hibernia royalties averaged $0.70 per barrel in 2002.

Terra Nova

The
Terra Nova oil field, which lies 350 kilometres east-southeast of St. John's, Newfoundland in 95 metres of water, was discovered by Petro-Canada in 1984. Petro-Canada is
operator of the field and holds a 34 per cent working interest in the development. The Terra Nova field is estimated to have a production life of approximately 12 to 14 years.

Development
of the Terra Nova field, including final commissioning of the floating production, storage and offloading (FPSO) vessel, was completed in early January 2002. Following
start-up on January 20, 2002, field production was steadily ramped up to regulatory allowable levels. In December 2002, the Canada-Newfoundland Offshore Petroleum Board
approved an increase in the allowable average annual production rate to 150 000 b/d. Annual production levels are affected by a number of factors including weather and sea states,
sea ice and iceberg conditions, well and reservoir performance and maintenance programs. Production in 2002 averaged 105 400 b/d (35 800 b/d net to
Petro-Canada). At 2002 year-end, six producing oil wells, three water injection wells and one gas injector were in operation. Terra Nova utilizes the
system of shuttle tankers and transshipment terminal that is used for Hibernia.

The
Terra Nova royalty regime has three tiers. The royalty consists of a sliding scale basic royalty payable throughout the project's life with two additional tiers of net royalties
payable upon the achievement of specified levels of profitability. The basic royalty is payable as a per cent of gross field revenue, with an initial rate of one per cent, and rises to
10 per cent depending on cumulative production levels and the occurrence of simple payout. After tier 1 payout, including a specified return allowance, has been reached, net royalty will
become the greater of the basic royalty or 30 per cent of net revenue. An additional net royalty equal to 12.5 per cent of net revenue will be payable once a further level
of payout, including an additional return allowance, is attained. In 2002, Terra Nova royalties averaged $0.40 per barrel.

White Rose

In
March 2002, Petro-Canada and Husky Oil Operations Limited, the operator, agreed to proceed with development of the White Rose oil field (Petro-Canada's ownership
interest  27.5 per cent). Development includes construction of an FPSO vessel with a production capacity of 100 000 barrels of
oil per day and a subsea production system. Field development plans anticipate 19 to 21 wells to recover an estimated 200 to 250 million barrels of oil over a 10- to
12-year time frame. Steel cutting for the hull of the FPSO commenced in the late fall in South Korea. Engineering and fabrication of the FPSO's topsides is underway in Marystown,
Newfoundland. Experience gained at Terra Nova has been incorporated into White Rose planning, which will greatly reduce project risks and uncertainties. First oil from the project is expected by
year-end 2005. Peak production at an anticipated 90 000 b/d (24 700 b/d net to Petro-Canada) is expected to be sustained for a period of
about four years. Two chartered tankers will ship White Rose production directly to markets. Petro-Canada's estimate of total project cost to first oil, including the cost of the first
10 wells, is $2.3 billion.

Other Offshore Exploration and Development

In
addition to current East Coast developments, Petro-Canada holds interests in the Hebron/Ben Nevis oil field discoveries, where our interest is 23.9 per cent. After
two years of comprehensive study, development work on the Hebron/Ben Nevis discoveries has been suspended. The potential for further advances in technology to lower development costs and
improve project economics will be monitored.

Elsewhere
offshore Newfoundland, Petro-Canada holds significant acreage interests in a number of unexplored or lightly explored areas, particularly in the Flemish Pass
and Salar basins, where the focus is on oil discovery. In February 2003, drilling began on the first of two deep water exploration wells in the Flemish Pass region.

Generic Offshore Newfoundland Royalty Regime

In
1996, the Government of Newfoundland and Labrador announced the main features of a royalty regime that will apply to the development of petroleum resources in offshore areas other than Hibernia and
Terra Nova. The generic offshore royalty regime consists of a sliding scale basic royalty payable throughout a project's life, and a two-tier net royalty payable upon the achievement of
specified levels of profitability. The basic royalty is calculated as a percentage of gross field revenue commencing at one per cent and rising to 7.5 per cent depending on
cumulative production levels and the achievement of simple payout. Upon reaching tier 1 payout, including a return allowance, the net royalty is calculated as the greater of the basic royalty
or 20 per cent of net revenue. An additional 10 per cent net royalty rate is payable once a higher level of return on investment is attained.

Oil Sands

Oil
Sands, one of Petro-Canada's core businesses, comprises our ownership position in Syncrude, the development of our extensivein situoil
sands properties, including MacKay River, and the potential to further integrate oil sands production with processing at our Edmonton refinery.

Syncrude

Petro-Canada
has a 12 per cent interest in Syncrude, the world's largest oil sands mining operation. Located north of Fort McMurray, Alberta, Syncrude is a joint venture
formed to mine shallow deposits of oil sands, and to extract and upgrade bitumen to produce synthetic crude oil. Syncrude has an estimated reserve life in excess of 35 years. Three mines are
currently in operation at Syncrude: the Base mine where operations are carried out using drag lines, bucket wheel reclaimers and belt conveyors; and the North mine and Aurora mine, where truck, shovel
and hydro-transport systems are in use. An extraction process recovers about 91 per cent of the crude bitumen contained in the mined sands. Refining processes upgrade the bitumen into
high quality, light (32 degree API) sweet synthetic crude oil.

In
1997, the Syncrude owners approved a staged growth strategy for the next decade. To date, plant expansions have increased Syncrude's annual production capacity from
200 000 b/d in 1996 to 260 000 b/d. The third stage expansion, currently underway, will increase the annual production capacity to
360 000 b/d by late 2005.

During
2001, Syncrude completed the transition from a project-specific contractual royalty to the Province of Alberta oil sands generic royalty. Effective January 2002, the
royalty payable by Syncrude to the Province of Alberta has been set at the greater of one per cent of gross revenue or 25 per cent of net revenue. The net revenue is determined by
subtracting allowed operating and capital costs from gross revenue. In 2002, the royalty paid was one per cent of gross revenue.

In Situ Oil Sands

In
September 2002, Petro-Canada successfully completed construction of its 100 per cent owned,in situbitumen
production facility at MacKay River. Following an initial reservoir steaming process, bitumen production commenced in November. Production at MacKay River in December averaged
9 400 b/d. Production will be ramped up steadily during 2003 to approximately 30 000 b/d, a level that MacKay River reserves can sustain for 25 years.
Bitumen is recoveredin situwhere oil sands are too deep to be mined economically. Our bitumen extraction process utilizes steam-assisted gravity
drainage (SAGD), a technology that Petro-Canada helped to develop. SAGD combines horizontal drilling with thermal steam injection. Steam is injected into the reservoir through the top well
of a horizontal well pair to mobilize the bitumen, which flows to the lower producing well. This technology can economically recover over 60 per cent of the bitumen in
place. The initial development phase at MacKay River includes two initial well pads of 12 and 13 horizontal well pairs. Well pairs are about 700 - 750 metres in
length and are expected to produce about 1 200 barrels of bitumen per day. On average, wells are expected to have a six- to eight-year life.
New well pads will be built and drilling will continue as necessary throughout the life of the field.

All
the water used in the steaming process will come from underground sources, with more than 90 per cent recycled  a key feature of
the environmental efficiency of the MacKay River facility. The bitumen production from the project is currently

10    Petro-Canada Annual Information Form

---

being transported to the Athabasca Pipeline Terminal via a lateral insulated pipeline leased from Enbridge. To enable onward shipment through major North American pipelines, the bitumen is diluted
with synthetic crude oil, provided under a long-term supply arrangement with Suncor Energy Marketing Inc. Through our long experience with a SAGD pilot project at an adjacent test
facility, operating technical risks at MacKay River have been minimized, resulting in high capital efficiency, lower operating costs and high reservoir confidence. Capital expenditures for the MacKay
River development came in at $274 million.

TransCanada
Energy Limited is currently constructing a co-generation facility that will provide MacKay River with a long-term assured supply of
low-cost power and steam and reduce greenhouse gas emissions by about 50 per cent when compared to the equivalent steam and electricity produced without
co-generation. The co-generation plant, which has a planned late 2003 start-up, will be owned by TransCanada Energy but operated as part of the MacKay River
project.

The
MacKay River operation is subject to the 1997 Alberta Oil Sands Royalty Regulation. Prior to royalty payout, which includes a specified return allowance, the royalty is calculated as
one per cent of gross revenue. After royalty payout, the royalty is based on the greater of one per cent of gross revenue or 25 per cent of net revenue. The net revenue is
determined by subtracting allowed operating and capital costs from gross revenue.

Late
in 2001, Petro-Canada filed a commercial application with the Alberta Energy and Utilities Board and Alberta Environment for the construction of an
80 000 b/d (60 000 b/d net to Petro-Canada) production facility at Meadow Creek, the selected site for our nextin
situdevelopment. Following public consultation and regulatory approval, we will make a decision on proceeding with Meadow Creek based on economic evaluations, our experience
at MacKay River, and clarification of requirements related to the Kyoto Protocol.

Our
longer-term plans include linking our bitumen production with processing at our Edmonton refinery. As a first step, in 2001, Petro-Canada filed an application
with regulatory bodies for approval to undertake a major refinery conversion program that would enable the Edmonton refinery to replace its existing light crude oil feedstock with bitumen, while
producing low-sulphur refined products. (Additional information regarding these plans can be found under Oil Sands within the Upstream Review and Outlook section of the MD&A.)

North American Natural Gas

Western Canada

Petro-Canada's
primary operating regions are Alberta and British Columbia where we are a major holder of developed and undeveloped natural gas rights. The Company also holds a number of
developed and undeveloped oil rights.

In
2002, we participated in 378 gross (225 net) wells, including 347 gross (202 net) gas and 4 gross (4 net) oil wells, for an
overall success rate of 93 per cent. Reserves extensions, discoveries, revisions and improved recovery added 207 billion cubic feet (bcf) of natural gas and
eight million barrels of conventional crude oil and natural gas liquids to proved reserves before royalties. Petro-Canada's finding and development costs for natural gas and associated
liquids averaged $1.56 per thousand cubic feet of gas equivalent (mcfe), compared with $1.52 in 2001. Our three-year average finding and development costs for natural gas and
associated liquids were $1.39/mcfe. (For comparison purposes, Petro-Canada converts 6 000 cubic feet of natural gas to one barrel of oil.) Property acquisitions
added 14 bcf of natural gas to reserves. Sales of producing properties with gross reserves totalling five bcf of natural gas were completed in the year. Annual production before
royalties totalled 263 bcf of natural gas and seven million barrels of conventional crude oil and natural gas liquids.

The
royalty regime is a significant factor in the profitability of crude oil and natural gas production. Royalties on conventional crude oil and natural gas owned by provincial
governments are determined by regulation and may be amended from time to time. Royalties are generally calculated as a percentage of production and vary depending upon factors such as well
production volumes, selling prices, method of recovery, location of production and date of discovery. Royalties payable on production of privately owned crude oil and natural gas are negotiated with
the mineral rights owner. In 2002, Petro-Canada's average royalty rates in Western Canada were 16 per cent for conventional crude oil and 23 per cent for
natural gas.

Petro-Canada's
natural gas program in Western Canada is focused on maintaining a concentrated, profitable production base. Our areas of concentration, particularly the
Alberta Foothills and northeast British Columbia, are characterized by large reserves, complex geology and a high level of infrastructure ownership by Petro-Canada. A key objective is to
add proved reserves at economic finding and development costs that at least replace produced volumes. With the increasing maturity of the Western Canada Sedimentary Basin, this objective is becoming
more challenging.

Petro-Canada
operates 12 natural gas field processing plants with total gross processing capacity of approximately 1.2 bcf of natural gas per day, of which our share
is approximately 693 mmcf/d. The key plants we operate are at Hanlan, Ferrier, Wildcat Hills and Brazeau in Alberta and Boundary Lake near the Alberta/British Columbia border. We also have
varying working interests in other natural gas processing plants and field gathering facilities operated by other oil and gas companies of which our share is approximately 239 mmcf/d of design
capacity.

We
market natural gas produced by other companies in addition to our own production. In 2002, we sold 926 mmcf/d, up three per cent from 900 mmcf/d in 2001. To
achieve better control over sales volumes, prices and transportation-related costs, we focus on direct sales to end users, distribution companies, wholesale marketers and natural gas spot markets. Our
marketing effort includes management of the gas portfolio, gas supply, pipeline commitments and customer relationships. The following table shows the market distribution of Petro-Canada's natural gas
sales.

Mackenzie Delta, Northwest Territories

With
interests in six blocks, covering approximately one million gross undeveloped acres (0.6 million net acres), Petro-Canada is one of the largest leaseholders in
the Mackenzie Delta. Petro-Canada's holdings comprise four exploration licences and two Inuvialuit land concessions. We are the operator of the four licences. Our net work commitments on
the four licences total

approximately $140 million over five years and are guaranteed by performance bonds totalling approximately $35 million. Work commitments on the Inuvialuit land concessions include
seismic acquisition and drilling a total of three wells. In 2002, a natural gas discovery at the Tuk M-18 well tested at restricted rates up to 30 mmcf/d.

Alaska

Our
focus in Alaska is the foothills area north of the Brooks mountain range. A field geological study has confirmed that the geology and prospectivity of the area is similar to the Alberta Foothills,
where Petro-Canada has developed considerable expertise and has had significant success finding natural gas. While it is unlikely the region will be serviced by a pipeline for some time,
Petro-Canada's acreage is close to a proposed pipeline route to southern markets. To comply with the State of Alaska regulations, late in 2002 Petro-Canada relinquished
a portion of our acreage to reduce our holdings below the maximum allowable of 500 000 acres. As a result, our landholdings at year-end totalled
410 500 acres (gross and net).

Future Commitments

The
Company has future commitments to sell and transport natural gas associated with normal operations. Under future fixed-price commitments entered into during the 1990's, approximately
four per cent of our estimated 2003 natural gas production has been sold at an average plant gate netback price of $2.73 per thousand cubic feet (mcf). In 2004, the volume of
natural gas sold under these fixed-price contracts will be about 40 per cent less than in 2003.

We believe that the reserve quantities are reasonable estimates consistent with current knowledge of the characteristics and extent of the
productive formations, but such estimates are subject to upward or downward revisions as additional information regarding producing fields becomes available, as technology improves and as economic
conditions change. Additional proved reserves are expected to be booked for Hibernia, Terra Nova, White Rose and MacKay River during the course of continuing development.

Petro-Canada's capital expenditure budget for Upstream Canada investments in 2003 is approximately $1 500 million.
Planned investments in our North American Natural Gas business total $455 million and include the drilling of at least one exploration well in the Mackenzie Delta. Spending plans for
Canada's East Coast include $140 million for ongoing Hibernia and Terra Nova drilling and development programs, $170 million for development of the White Rose project, and
$40 million for two exploratory wells in the Flemish Pass. Anticipated investments in oil sands include about $255 million for the Company's share of Syncrude's planned
expenditures and an estimated $415 million for other oil sands opportunities, including the proposed bitumen feed conversion project at the Edmonton refinery and the development of our planned
Meadow Creek bitumen project. Final decisions on whether or not to go ahead with the feed conversion at the Edmonton refinery and the Meadow Creek project will remain pending until regulatory approval
is received and until the implications of the Kyoto Protocol on project economics are made clear.

Upstream International

Following the acquisition of international oil and gas interests in 2002, Petro-Canada established international operations as a core business unit.
International operations are focused on three exploration and production regions: Northwest Europe, principally the North Sea; North Africa/Near East, where our previously modest positions in Algeria,
Tunisia and Libya have been significantly expanded through the addition of new exploratory and producing interests in Syria, Libya and Kazakhstan; and Northern Latin America where we have interests in
a major gas producing operation in Trinidad and a prospective development in Venezuela. Integration of the new oil and gas businesses acquired from Veba was essentially completed prior to
2002 year-end. Rights of first refusal were exercised by third parties with respect to Veba's assets in Norway and Egypt and a remaining right of first refusal with respect to
Veba's heavy oil assets at Cerro Negro in Venezuela was unresolved at year-end.

The
following table shows our estimates of Petro-Canada's international proved crude oil reserves before royalties and average daily production of crude oil before royalties
by major fields.

Northwest Europe

In
Northwest Europe, all of Petro-Canada's production comes from the United Kingdom and the Netherlands sectors of the North Sea. Exploration programs extend into Denmark and the Faroe
Islands. Our major focus is the North Sea, where extensive development has taken place since the early 1970's. While the basin is now a mature play, moderate-size fields continue to be
developed and exploited.

In
the U.K. sector, Petro-Canada has interests in three operated and 14 non-operated licences. We are focused on two areas: the Outer Moray Firth
and Central North Sea. In the Outer Moray Firth, we hold a 20.6 per cent working interest in the Scott oil field and production platform and a 9.4 per cent working interest
in the Telford oil field, a subsea tieback to the Scott platform. High quality crude oil from Scott and Telford is exported to shore via the Forties Pipeline System; associated gas is exported via the
SAGE gas pipeline system. In Central North Sea, our interests are centered on the Triton development area. This is a joint development of the Petro-Canada operated Guillemot West and
Northwest fields (Petro-Canada working interest  80 per cent) and Bittern field (Petro-Canada working
interest  4.6 per cent). The development combines subsea technology with a central FPSO vessel. The fields are tied back to the Triton FPSO
(Petro-Canada working interest  30 per cent). The tie-back of the western extension of the Guillemot Northwest field was
completed in 2002. Seven oilwells and one gas producer are currently in operation at the Guillemot West and Northwest fields. The high quality crude oil is shipped via shuttle tanker, while gas is
exported through the SEGAL system. The Clapham field, with peak production of about 15 000 b/d, is expected to come on-stream in 2004.

In
the Netherlands sector, we have interests in three operated and 20 non-operated licences. This portfolio encompasses interests in 17 producing gas fields
spread out over eight offshore and two onshore production licences. The major source of gas production is from blocks L8b and L5c (Petro-Canada working
interests  25 per cent and 30 per cent, respectively). Petro-Canada also holds a 12 per cent interest in
the BP-operated onshore Bergen gas storage facility. Petro-Canada's oil production from the Netherlands sector is primarily from the Petro-Canada operated Hanze
field (Petro-Canada working interest  45 per cent). At 2002 year end, development was underway on a gas discovery on
block L5b (Petro-Canada working interest  30 per cent). Project production will be from two wells to be connected to the
existing production platform on the L8-P4 field (Petro-Canada working interest  28.3 per cent). Production is
expected to be on-stream in the first quarter of 2004.

In
the U.K. and Netherlands sectors of the North Sea, our strategy is infrastructure-centred with the focus on low-risk drilling prospects and undeveloped discoveries that
can be brought into production rapidly. In Danish waters we hold interests in four non-operated licences. In the Faroe/West Shetlands area we have interests in two non-operated
licences.

North Africa/Near East

Combining
North Africa, Syria and Kazakhstan, this core region provides a substantial portion of Petro-Canada's international production. Improved oil recovery opportunities in Libya (the
Amal and Ghani/Zenad Farrud fields) and Syria (over 30 fields) exist, in addition to exploration opportunities.

In
Syria, Petro-Canada's interests are consolidated under production sharing contracts with Syria Shell Petroleum Development and the Syrian Petroleum Company. The joint
venture, under the name Al Furat Petroleum Company (AFPC), produces about 55 per cent of Syrian production. AFPC produces oil and gas from 36 fields with 220 wells over
three concession areas. Petro-Canada's working interests range from 33 to 37 per cent. The near term goal of AFPC is to sustain gross production at the
300 000 b/d level for the next few years through improved recovery from existing fields. Oil produced by the joint venture is exported via the Scot pipeline to the Banias terminal.
The natural gas production is sold into the Syrian domestic system.

In
Libya, Petro-Canada is one of the country's largest producers. Our major interest in Libya is a 49 per cent participating interest in a joint venture with
the National Oil Corporation of Libya (NOC). Operation of the joint venture encompasses our exploration and producing interests in eight concessions, covering 25 190 square
kilometres. Petro-Canada also has equity interests in the Ras Lanuf export terminal and various pipelines. Most of the concessions are onshore in the Sirte basin. Currently, production
from the joint venture is from the combined operations of more than 20 fields.

Under
a separate Exploration and Production Sharing Agreement (EPSA) with NOC, Petro-Canada also holds an interest in the 2.4 million-acre En Naga
block, which is also located in Sirte basin and contains the En Naga North and En Naga West oil fields, as well as exploration acreage. Development of the two fields,
including construction of a related 96-kilometre pipeline to the Samah field, was nearing completion at 2002 year-end. Initial production from the project (Petro-Canada
working interest  50 per cent) is expected to come on-stream at a rate of 6 800 b/d (3 400 b/d
net to Petro-Canada) in 2003. Libyan production is high quality, low sulphur (sweet) crude oil. The country is a major oil exporter, particularly to Europe. Libya is a member country in
the Organization of the Petroleum Exporting Countries (OPEC). As such, production in that country may be constrained from time to time by OPEC quotas.

In
Algeria, Petro-Canada and Sonatrach, the Algerian national oil company, are parties to a production sharing agreement for the exploration and development of the Tinrhert
block, located over 1,000 kilometres southeast of Algiers. Petro-Canada acts as the operator of this project. We have a 70 per cent interest in the Tamadanet oil field,
located on the Tinrhert block, with Sonatrach holding the remaining 30 per cent. In 2002, our total share of production before royalty and the sharing of profit oil averaged
1 600 b/d, down from 2 300 b/d in 2001 due to natural decline. An exploration well that was drilled and abandoned in 2002 completed our drilling
obligations under the second phase of the production sharing contract.

In
Tunisia we have an agreement with the Tunisian national oil company, ETAP, to explore jointly on the 1.8 million acre Tataouine Block in south central Tunisia. In 2000,
we elected to proceed with the exploration licence phase of the agreement. Our drilling plans are pending the results of ongoing seismic evaluation.

In
Kazakhstan, we have a 40 per cent working interest in the Temir production sharing contract, with modest production from temporary facilities in the Saigak oil field
operated by Maersk Oil Kazakhstan. On completion of a central production facility early in 2003, we expect production from the Saigak field to increase to 12 000 b/d
(4 800 b/d net to Petro-Canada).

Northern Latin America

In
Northern Latin America, Petro-Canada's operations are focused on Trinidad where we hold a 17.3 per cent working interest in the North Coast Marine Area-1 gas
project in partnership with the operator, British Gas. Our participation is governed by a production-sharing contract. The current program includes development of three gas
fields  Hibiscus, Poinsettia and Chaconia. Commissioning of the Hibiscus production platform was completed in August. Natural gas production came on stream in
the third quarter of 2002, with our share averaging 32 mmcf/d over the remaining months of the year. Project production is being delivered by pipeline to the Atlantic LNG facility at Point
Fortin for liquefaction and subsequent sale into United States markets. Atlantic LNG is currently building an additional production train, which is expected to be on stream in mid 2003. As a result of
this expansion we expect our share of production to increase to 60 mmcf/d.

Late
in 2002, Petro-Canada completed the acquisition from Veba of a 50 per cent working interest in the La Ceiba block that straddles the eastern shores of Lake
Maracaibo in western Venezuela. While a 30 per cent interest in this block formed part

of the original Veba acquisition, the asset was excluded pending resolution of pre-emptive rights. In the interim, Veba, with Petro-Canada's consent, acquired an additional
20 per cent interest from a third party. Commercial development of hydrocarbon resources discovered on the block continues to be evaluated. A remaining right of first refusal concerning
Veba's Cerro Negro heavy oil operations in Venezuela was unresolved at year-end.

Edmonton Refinery

The
Edmonton refinery is Petro-Canada's largest and most efficient refinery, producing a high yield of light oils. The Edmonton refinery can use synthetic crude oil for up to
40 per cent of its feedstock. Synthetic crude oil produces a higher yield of gasoline and middle distillates than conventional crude oil. All of the Edmonton refinery's feedstock is
domestic crude oil.

Our
longer-term plans include linking our expanding bitumen production in Alberta with processing at our Edmonton refinery. (Additional information on these plans is provided
under Oil Sands in the Upstream Review and Outlook section of Management's Discussion and Analysis)

Montreal Refinery

The
Montreal refinery, supplied with imported crude oil primarily through the Portland-Montreal pipeline, has a flexible configuration allowing it to process a variety of crude oils, including heavy
grades, and intermediate feedstocks. The refinery produces gasolines, distillates, asphalts, petrochemicals, lubricant feedstocks and solvents.

Oakville Refinery

The
Oakville refinery is supplied with both domestic and imported crude oil. A variety of domestic crude oil types are supplied through the Enbridge pipeline system. Since May 1999, offshore
light crude oil is supplied via the Portland-Montreal pipeline, through Montreal and the Enbridge Line 9. The refinery produces a wide range of products including gasolines, distillates, asphalts and
lubricant feedstocks for Petro-Canada's lubricants plant.

Supply

Petro-Canada
purchases crude oil and other refinery feedstocks from Canadian and international sources under a number of different contractual arrangements. The Downstream is responsible
for arranging domestic and foreign crude supply for our refineries. There is a well-developed infrastructure for third party supply of both domestic and imported crudes to markets
in North America. Purchases are generally through short-term renewable contracts. Petro-Canada is not dependent on any single source of supply for conventional crude oil and does not
anticipate any difficulty in obtaining an adequate supply in the foreseeable future.

Distribution

Petro-Canada
operates an extensive distribution network, utilizing pipeline, road, rail and marine transportation, to deliver refined products to retail outlets, and commercial and
industrial customers. We hold interests in two refined product pipelines and operate 12 major refined product terminals across Canada.

Distribution
efficiencies are achieved through refined product exchange, purchase, sale and short-term storage arrangements with other petroleum companies. These arrangements
reduce capital and transportation costs, assist in the maintenance of supply to customers and enable us to participate in geographical areas without the need to invest capital in distribution
facilities. Applicable agreements contain appropriate provisions for consistent product quality to be maintained for our customers.

Sales and Marketing

Petro-Canada
is the second largest marketer of petroleum products in Canada. In 2002 Petro-Canada's petroleum product sales represented approximately 17 per cent
of total petroleum products sold in Canada. Petro-Canada markets a full range of petroleum products including gasolines, diesel oils, heating oils, aviation fuels, heavy fuel oils,
asphalts, lubricants, petrochemical feedstocks and liquefied petroleum gases. Petro-Canada also generates non-petroleum revenue from convenience stores, car washes and
automotive repair and maintenance services.

The
following table shows the approximate average daily volumes of petroleum products sold during the years indicated.

Retail

At
December 31, 2002, Petro-Canada's network of retail sites consisted of 1 537 outlets across Canada, of which 903 are Company-controlled with the others operated by
third parties. Independent dealers and agents operate virtually all of the outlets.

Wholesale and Refinery Sales

Petro-Canada
sells petroleum products into the farm, home heating, paving, small industrial, commercial and truck markets. This category accounts for approximately
65 per cent of total Downstream sales volumes. Petro-Canada has the largest network of fueling centres to serve the trucking market in Canada, with 208 Petro-Pass
sites.

We
also sell large volumes of petroleum products directly to large industrial and commercial customers and independent marketers. Asphalt, a key product for Petro-Canada,
allows us to leverage our heavy crude capability at our Oakville and Montreal refineries. Asphalt total sales volume in 2002 was approximately 1.6 billion litres.

Lubricants

The
Lubricants Centre, located in Mississauga, Ontario, produces specialty lubricants and waxes that we market in Canada and internationally. Petro-Canada is the largest producer of lube
base stocks in Canada with annual base oil production capacity in excess of 700 million litres, and the largest producer of white oils in the world.

The
lubricants plant utilizes a two-stage hydro-treating process, which is unique in Canada. This process enables Petro-Canada to refine gas oils produced from a
wide range of crude feedstocks into lubricating oil base stocks with the highest level of purity of any base stocks in Canada. Advancing lubricant technology and environmental concerns continue to
increase the demand for high purity, hydro-treated base stocks for many lubricant applications, and Petro-Canada is well positioned to meet this growing demand.

Our
strategy is focused on leveraging technological and quality advantages by growing volume in high-margin channels. Products in this high-margin category include pharmaceutical grade
white oils, high viscosity index oils for use in high-end industrial applications, next-generation engine oils and transmission fluids. In 2002, high-margin sales accounted for over 60 per cent
of total lubricant sales. Petro-Canada currently sells over two-thirds of its manufactured lubricants outside of Canada, and the growing global demand for these higher quality products offers
significant opportunity for long-term growth.

|                           |  |                         

Petro-Canada's 2003 capital expenditures budget for downstream operations amounts to approximately $500 million. The major portion of 2002 expenditures
and those planned for 2003 are focused on investments to comply with federal requirements for the reduction of sulphur levels in gasoline and on the accelerated roll-out of our
new-image retail sites.

---

Research and Development

Petro-Canada owns a research facility at Sheridan Park in Mississauga, Ontario, where we conduct research on lubricants. In 2002,
Petro-Canada's expenditures on research and development activities were approximately $6 million.

As
global advancements in fuel cell technology continue to occur, the Fuelling a Cleaner Canada Association (Petro-Canada, Ballard Power Systems and Methanex Corporation) has
focused its efforts on working with various government agencies, such as the Canadian Transportation Fuel Cell Alliance (CTFCA), in an effort to ensure appropriate funding and the optimization of
independent activities directed towards the implementation of fuel cell pilot demonstrations. In addition, through the CTFCA, knowledge from other pilot projects such as the California Fuel Cell
Partnership can be shared, thereby assisting in the advancement of Canadian demonstrations.

---

Human Resources

At December 31, 2002, Petro-Canada and its wholly owned subsidiaries had 4 470 employees, compared with
4 178 employees at December 31, 2001. At year-end, Upstream Canada employed 1 019, Upstream International 261 and the Downstream 2 501,
with the remaining 689 being corporate support staff. Approximately 25 per cent of Petro-Canada's employees are covered by collective bargaining agreements. Approximately
96 per cent of our unionized employees are members of the Communications Energy and Paperworkers Union (CEPU) that represents refinery, marketing and gas plant workers. Current
three-year collective bargaining agreements with the CEPU run until February 1, 2004.

Industry Conditions

Oil prices are subject to international supply and demand. Political developments, especially in the Middle East, can affect world oil supply and oil prices.
Natural gas prices are primarily affected by supply and demand in North America and, to a lesser extent, by prices of alternate sources of energy. Petro-Canada expects continued volatility
and uncertainty in oil and natural gas prices.

Crude
oil prices are generally set in U.S. dollars, while sales of refined petroleum products are primarily in Canadian dollars. Fluctuations in exchange rates between the U.S.
and Canadian dollar may therefore give rise to foreign currency exposure.

The
Canadian and international petroleum industry is highly competitive in all aspects, including the exploration for and development of new sources of supply, the construction and
operation of pipelines and the refining, distribution and marketing of petroleum products. The Company competes in virtually every aspect of its business with other large integrated oil and gas
companies. In export markets, the Company encounters active competition from other Canadian producers and foreign producers. The petroleum industry also competes with other industries in supplying
energy, fuel and related products to consumers.

Exploration,
production and refining require high levels of investment and have particular economic risks and opportunities. They are subject to hazards such as fire, explosion, blowouts
and oil spills that can cause personal injury, damage to property, equipment and the environment and resulting interruption of operations.

The
petroleum industry is also subject to regulation and intervention by governments in such matters as the award of exploration and production rights, the imposition of specific
drilling obligations, environmental protection controls, control over the development and abandonment of fields (including restrictions on production) and, possibly, expropriation or cancellation of
contract rights.

Risks
attaching to foreign operations include, but are not limited to: international unrest and conflict; changes in laws affecting foreign ownership, fiscal regimes, exchange controls
and the repatriation of funds; and foreign exchange rates.

Share Ownership

At December 31, 2002, the directors and officers of Petro-Canada, as a group, beneficially owned or exercised control over
155 356 common shares or less than one per cent of the common shares of the Corporation outstanding as of such date.

ITEM 9  ADDITIONAL INFORMATION

---

Relationship with the Government of Canada

The following is a summary of certain agreements entered into by Petro-Canada with its principal shareholder, the Government of Canada, at the time
of Petro-Canada's initial public offering of shares in July, 1991, and certain charter restrictions applicable to Petro-Canada.

---

Government of Canada Shareholding

The Government of Canada owned 18.74 per cent of the 263,594,977 common shares issued and outstanding as of December 31, 2002. The
Government of Canada has stated that it will deal with its shares as an investor and not as a manager and that, in order to reflect the rights of other shareholders, it does not intend to exercise the
right to vote at meetings of shareholders although it reserves the right to do so. So long as the Government of Canada holds 10 per cent or more of the outstanding voting shares it will
have the right to designate one nominee for election to a board comprising between nine and 13 directors. The Government's current nominee is John F. Cordeau.

Pursuant
to an agreement dated May 9, 1991 (the "Petro-Canada Privatization Agreement"), Petro-Canada and the Government of Canada have agreed that the
Government will have the right to participate up to the extent of its percentage ownership in any proposed equity offerings by Petro-Canada so long as it remains the registered holder of
10 per cent or more of the outstanding common shares. So long as the Government of Canada remains the holder of 10 per cent or more of the outstanding common shares,
Petro-Canada will not have the right to participate in any offering of Petro-Canada shares by the Government, unless the Government agrees.

---

Ownership, Voting and Other Charter Restrictions

ThePetro-Canada Public Participation Actrequires that the Articles of Petro-Canada
include certain restrictions on the ownership and voting of voting shares of the Corporation. The common shares of Petro-Canada are voting shares.

No
person, together with associates of that person, may subscribe for, have transferred to that person, hold, beneficially own or control, otherwise than by way of security only, or
vote, in the aggregate, voting shares of Petro-Canada to which are attached more than 20 per cent of the votes attached to all outstanding voting shares of
Petro-Canada other than voting shares held by the Government of Canada.

As
required by thePetro-Canada Public Participation Act, Petro-Canada's Articles contain provisions for the enforcement of
these restrictions, including provisions for suspension of voting rights, forfeiture of dividends, prohibitions against share
transfer, compulsory sale of shares, redemption and suspension of other shareholder rights. The board of directors of Petro-Canada may at any time require holders of or subscribers for
voting shares and certain other persons to furnish statutory declarations as to residence, ownership of voting shares and certain other matters relevant to the enforcement of the

44    Petro-Canada Annual Information Form

---

restrictions. Petro-Canada is prohibited from accepting any subscription for, issuing or registering a transfer of any voting shares if a contravention of the individual or
non-resident ownership restrictions result.

Petro-Canada's
Articles also include provisions requiring Petro-Canada to maintain its head office in Calgary, Alberta; prohibiting Petro-Canada from
selling, transferring or otherwise disposing of all or substantially all of its assets in one transaction or several related transactions, to any one person or group of associated persons or to
non-residents, otherwise than by way of security only in connection with the financing of Petro-Canada; and requiring Petro-Canada to ensure (and to adopt, from
time to time, policies describing the manner in which Petro-Canada will fulfil the requirement to ensure) that any member of the public can, in either official language of Canada (English
and French), communicate with and obtain available services from Petro-Canada's head office and any other facilities where Petro-Canada determines there is significant demand
for communications with and services from that facility in that language.
