FOR IMMEDIATE RELEASE


FIRST QUARTER 2001

SUNCOR ENERGY REPORTS RECORD QUARTERLY EARNINGS AND CASH FLOW

COMMODITY PRICES, IMPROVED REFINING MARGINS, CONTRIBUTE TO EARNINGS IMPROVEMENT


FIRST QUARTER SUMMARY

(ALL FINANCIAL FIGURES ARE IN CANADIAN DOLLARS UNLESS NOTED OTHERWISE.)

-    First quarter earnings for 2001 rose to a record $125 million, up from $105
     million in the first quarter of 2000.

-    Cash flow from operations was a record $275 million, compared with $269
     million during the same period last year.

-    Total daily production for Suncor averaged 135,100 barrels of oil
     equivalent(1) (BOE), a decrease over the first quarter daily average in
     2000 of 148,600 BOE.

-    Oil Sands production averaged 113,400 barrels per day in the quarter,
     compared with 114,800 barrels per day in the first quarter of 2000. Sales
     in the quarter were 106,500 barrels per day, down from 117,900 barrels per
     day in the first quarter of 2000.

-    Due to lower sales volume and higher energy costs, Oil Sands base plant
     cash operating costs increased to $12.65 per barrel compared with $11.10
     per barrel in the first quarter of 2000.

-    Project Millennium reached the 80 per cent completion mark. Project costs
     spent to date are $2.65 billion.

-    Suncor's Natural Gas business produced an average of 21,700 BOE per day
     compared with 33,800 BOE per day during the first quarter last year.
     Production during the quarter consisted of 177 million cubic feet per day
     of natural gas; 2,300 barrels per day of natural gas liquids; and 1,700
     barrels per day of crude oil.

-    Refining margins for Sunoco improved almost 15 per cent, averaging 6.2
     cents per litre (cpl) compared with 5.4 cpl in the first quarter of 2000.
     Retail gasoline margins for Sunoco's branded retail outlets were 6.1 cpl
     compared to 6.8 cpl in the first quarter of 2000.

</TABLE>

Earnings for the first quarter of 2001 rose to a quarterly record of $125
million ($0.53 per common share), up from $105 million ($0.45 per common share)
in the first quarter of 2000. The improvement was primarily a result of
increased commodity prices (including the impact of a weaker Canadian dollar
versus the U.S. dollar), higher downstream refining margins and a lower crude
oil hedging loss. These favourable factors were partially offset by lower sales
volumes, a higher light/heavy crude oil differential, higher interest expenses,
start-up costs associated with Project Millennium, and Stuart Oil Shale Project
costs.

During the first quarter, cash flow from operations was a record $275 million
($1.19 per common share), compared with $269 million ($1.16 per common share) in
the first quarter of 2000. Revenue was $1 billion compared with $779 million
during the same period in 2000.

"Continued strong crude oil prices, higher natural gas prices and improved
downstream refining margins gave Suncor a strong start to the year," said Rick
George, president and chief executive officer. "To sustain these record returns
Suncor will continue to focus on improving operational reliability and reducing
operating costs an effort aimed at driving higher returns through production
growth, not commodity prices."

During the quarter Suncor recorded a $45 million hedging loss from its crude oil
hedging program, compared to a loss of $51 million in the first quarter of 2000.

Total production of crude oil, natural gas and natural gas liquids averaged
135,100 BOE per day, a decrease from the 2000 first quarter average of 148,600
BOE per day. The decrease reflects lower production from the Natural Gas
business primarily due to last year's property divestments.

OIL SANDS PRODUCTION STEADY

Oil Sands recorded earnings of $69 million in the first quarter, compared with
$90 million in the same quarter of 2000. Cash flow from operations declined to
$140 million, down from $199 million in the first quarter of 2000.

Oil Sands production in the quarter averaged 113,400 barrels per day, compared
with 114,800 barrels per day in the first quarter of 2000, mainly due to ore
quality variability in February. A maintenance shutdown in early April, which
allowed for repairs to the 5C9 fractionating tower, is expected to improve
production rates during the remainder of the year. Oil Sands original production
target of 130,000 barrels per day for 2001 includes the estimated impact of this
maintenance.

Sales volumes for the quarter declined to 106,500 barrels per day from 117,900
barrels per day in the first quarter of 2000. The decline occurred as Suncor
built back inventory to normal operational levels. Inventory had declined to
help meet customer requirements during the 5C9 maintenance shutdown.

Cash operating costs increased to $12.65 per barrel compared with $11.10 per
barrel in the first quarter of 2000. The increase was due to the lower sales
volume and higher energy costs. The first quarter costs for 2001 increase to
$15.40 per barrel when Project Millennium start-up costs are included.

</TABLE>

Several milestones for advancing Project Millennium were met during the quarter,
including successfully testing improved extraction technology that is expected
to operate at a lower cost and be easier to maintain than the existing method;
and completion of a continuous water recycling system that should contribute to
energy efficiency by recycling waste heat and reducing water use. Construction
was also completed on TransAlta's co-generation facility, where a portion of the
output will help meet Suncor's long-term needs for electricity and steam.

"We're making significant progress and expect to complete Project Millennium on
schedule," said George. "We are on track to deliver on our commitments for
growth and see our average daily oil production capacity increase to 225,000
barrels per day by year-end."

By the end of the quarter, Project Millennium had reached the 80 per cent
completion mark with engineering, equipment and material purchases all
essentially complete. Project expenditures at the end of the first quarter were
$2.65 billion. Suncor's current $2.8 billion estimate remains unchanged,
however, construction cost pressures continue to challenge the project.
Construction productivity in the second quarter will be important. Suncor
expects to provide a final cost estimate early in the third quarter when the
project is expected to be over 90 per cent complete.

NATURAL GAS SETS RECORD FOR EARNINGS AND CASH FLOW

Natural Gas earnings increased to $53 million in the first quarter, up from $8
million in first quarter of 2000. Cash flow from operations for the quarter was
$127 million compared with $48 million for the first quarter 2000.

Production averaged 21,700 BOE per day compared with 33,800 BOE per day during
the first quarter last year. Natural gas production in the quarter averaged 177
million cubic feet (mmcf) per day down from 222 mmcf per day in the first
quarter of 2000. The decrease primarily reflects property divestments that
occurred last year and natural reservoir decline.

"One year after unveiling its new strategy, Natural Gas has made progress in
building and sustaining a profitable business," said George.


SUNOCO EARNINGS DRIVEN BY REFINING MARGINS

Sunoco's first quarter earnings were $23 million, compared with $19 million in
the first quarter of 2000. Cash flow from operations was $50 million for the
quarter compared with $46 million in the same quarter in 2000.

In the first quarter, refining margins improved almost 15 per cent, averaging
6.2 cents per litre (cpl) compared with 5.4 cpl in the first quarter of 2000.
Strong demand for gasoline and distillates in North America accompanied by low
inventories contributed to the improved margins. Sales volumes increased by more
than four per cent over the same quarter last year.

In January, operational problems associated with the Sarnia Refinery's catalytic
cracker increased maintenance costs and resulted in Sunoco making product
purchases to ensure customer requirements were met. The cat cracker returned to
full production later that same month.

Retail gasoline margins for Sunoco's branded retail outlets were 6.1 cpl
compared to 6.8 cpl in the first quarter of 2000. The decline is primarily due
to competitive market pressures and price related costs for Sunoco's customer
loyalty program. A three per cent improvement in retail gasoline sales volumes
at Sunoco's branded retail sites partially offset the margin decline.


STUART OIL SHALE

Subsequent to the end of the quarter, Suncor sold its interest in the Stuart Oil
Shale Project to Southern Pacific Petroleum and Central Pacific Minerals
(SPP/CPM) and will record a write off in the second quarter of $3 million.

"While we think the Project has potential for the future, we had to make a
choice among competing growth priorities," said George. "For Suncor, it makes
sense to focus our people and resources on growing our core businesses in
Canada."


PROGRESS ON SUSTAINABLE DEVELOPMENT

Suncor's plan to establish an alternative and renewable energy business was
advanced during the quarter with the company acquiring a $3 million minority
equity interest in Northern Power Systems - a Vermont based firm that
specializes in wind and solar energy. The two companies have also signed a
non-binding letter of intent to form a joint venture to develop large-scale wind
power generation and other renewable energy projects in Canada.

Suncor Energy is an integrated Canadian energy company. Its Oil Sands business
mines and upgrades oil sand and markets custom-blended refinery feedstock and
diesel fuel. Suncor is also a conventional natural gas and oil producer in
Western Canada and operates a refining and

marketing business in Ontario under the Sunoco brand. At the same time as Suncor
meets today's energy needs, the company is also investing in alternative and
renewable energy for the future. Suncor Energy common shares (symbol SU) and
preferred securities are listed for trading on the Toronto and New York Stock
exchanges.

SUNCOR ENERGY INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1.    ACCOUNTING POLICIES

These financial statements follow the same accounting policies and methods of
computation as, and should be read in conjunction with, the most recent
annual financial statements, with the exception to the elimination of
intercompany sales as discussed in note 2.

2.    ELIMINATION OF INTERCOMPANY SALES

During the first quarter of 2001, the company changed the methodology of
accounting for sales from its upstream operations (Oil Sands and Natural Gas)
to its downstream operations (Sunoco) from a deeming concept to the actual
tracking of product shipped. This change was made to better reflect the
current operational activities within the company. This prospective change
will equally increase sales and other operating revenues and purchases of
crude oil and products by $96 million and will have no impact on consolidated
and segmented net earnings in the accompanying financial statements.

3.    START-UP EXPENSES

Start-up expenses represent pre-operating costs incurred in the commissioning
of the company's Oil Sands Project Millenium.

5.    SUBSEQUENT EVENT - OIL SHALE PROJECT

Effective April 5, 2001, the company sold its interest in the Stuart Oil
Shale Project to its partners in the joint venture Southern Pacific Petroleum
and Central Pacific Minerals (SPP/CPM). In consideration, the company will
retain a 5% royalty interest in Stage 1 of the project and each party will
retain its world wide rights to the technology. The company will make total
payments as part of the transaction in the amount of AUD$7 million, which
SPP/CPM will use to fund Stage 1 operating, capital and transition costs. The
company will receive 2.5 million SPP shares and 0.926 million CPM shares in
consideration. SPP/CPM will issue the company 12.5 million SPP share options
and 4.6 million CPM share options, exercisable over five years at a strike
price of AUD$1.25 per SPP share and AUD$3.38 per CPM share.

During the second quarter of 2001, the company will write off the carrying
value of the capital assets, surrender its partly paid Restricted Class
shares and extinguish the long term borrowings and accrued interest. The
resulting after tax charge of the divestment will be $3 million.
