FOR IMMEDIATE RELEASE

JANUARY 21, 2003

    PRODUCTION INCREASE OF 53% BOOSTS FINANCIAL PERFORMANCE AT SUNCOR ENERGY
      COMPANY SETS NEW RECORDS, EXCEEDS BILLION DOLLAR MARK FOR CASH FLOW

ALL FINANCIAL FIGURES ARE UNAUDITED AND IN CANADIAN DOLLARS UNLESS NOTED
OTHERWISE. NATURAL GAS CONVERTS TO BARRELS OF OIL EQUIVALENT AT A 6:1 RATIO (SIX
MILLION CUBIC FEET OF NATURAL GAS CONVERTS TO ONE THOUSAND BARRELS OF OIL
EQUIVALENT).

CALGARY, ALBERTA - Suncor Energy Inc. announced today that it boosted production
by 53 per cent in 2002, a key contributor to generating record financial
performance for the company. In 2002 net earnings were $761 million ($1.64 per
common share), compared to the company's previous record of $388 million ($0.79
per common share) in 2001. For the first time in the company's history, cash
flow provided from operations exceeded the billion dollar mark, increasing to
$1.44 billion ($3.11 per common share) in 2002, compared to $831 million ($1.76
per common share) in 2001.

Excluding a non-recurring gain on the sale of the company's retail natural gas
marketing business, a positive future tax revaluation, and the effects of
foreign currency translation on U.S. dollar denominated long-term debt and
preferred securities, 2002 net earnings were $708 million ($1.52 per common
share).

It was Suncor's expanded oil sands operations, buoyed by rising commodity
prices, which enabled record breaking financial performance.

Total company production for the year averaged 239,500 barrels of oil equivalent
(BOE) per day, up from the 156,600 BOE per day average recorded in 2001.
Suncor's oil sands facility generated the largest part of this total, averaging
205,800 barrels per day during 2002, compared to production of 123,200 barrels
per day in 2001.

"We ended the year with strong operational performance. For the first time in
the company's history, we exceeded the billion dollar mark for cash flow,
generating record-setting financial results for our shareholders," said Rick
George, president and chief executive officer. "The goal now is to carry that
momentum into 2003, increasing oil sands production while reducing operating
costs and positioning the company for future growth."

In 2002, cash operating costs at Suncor's oil sands operation averaged $13.20
per barrel (excluding start-up costs). Suncor expects the 2003 average to be
reduced to $12.50 per barrel (excluding start-up costs), which takes into
account a 30-day maintenance shutdown of one of the company's two oil sands
upgraders during the second quarter.

"We're going to be relentless in our drive to bring down costs with a goal of
exiting 2003 with cash operating costs at $10 to $11 per barrel," said George.


                                                                               1


Suncor's total production plan for 2003 is about 250,000 BOE per day. This
represents average production of 215,000 barrels per day from the company's oil
sands operation and about 35,000 BOE per day from Suncor's natural gas business.
Growth projects continue to be a focus for the company, as Suncor's Firebag
In-situ Oil Sands Project and vacuum tower expansion remain on budget and on
schedule. Together, these two projects are expected to increase production at
Suncor's oil sands operation to an average of 260,000 barrels per day in 2005.

"Suncor is going into 2003 with four key priorities. In the next twelve months
we will focus on reducing costs and increasing production from our existing oil
sands assets, while continuing to build the foundation for the next stages of
our oil sands growth strategy," said George. "At the same time, we plan to
continue to direct part of our cash flow to reducing Suncor's net debt."

In 2002, the company paid down more than $450 million of its net debt. As of
December 31, 2002 the company's net debt was $2.7 billion. Suncor is targetting
to reduce that to $2.4 billion by the end of 2003.

FOURTH QUARTER, 2002

Net earnings for the fourth quarter of 2002 were $258 million ($0.56 per common
share), compared to $26 million ($0.04 per common share) in the fourth quarter
of 2001. Suncor's cash flow provided from operations for the fourth quarter was
$460 million ($1.00 per common share), compared with $133 million ($0.27 per
common share) during the same period last year.

Excluding the effects of foreign currency translation on the company's U.S.
dollar denominated long-term debt and preferred securities, 2002 fourth quarter
net earnings were $256 million ($0.55 per common share).

Suncor's production for the fourth quarter of 2002 averaged 261,800 BOE per day,
compared with 186,700 BOE per day during the same period in 2001.

The higher production numbers reflect increased capacity at Suncor's oil sands
business where fourth quarter production exceeded design capacity, averaging
227,600 barrels per day, up from the 153,000 barrels per day the operation
generated during the fourth quarter of 2001. A planned nine-day maintenance
shutdown on one of two sets of hydrotreaters in November did not impact total
production, but did reduce the proportion of higher value sweet crude in
Suncor's sales mix for the quarter.

In the fourth quarter, Suncor realized after-tax crude oil and foreign exchange
hedging losses of approximately $55 million. For 2002, hedging losses were $160
million after-tax, compared to $148 million in 2001.

--------------------------------------------------------------------------------------------------------------------
* Production at Suncor's oil sands operation will be lower than capacity as a
result of a 30-day maintenance shutdown, scheduled to start April 28. The
maintenance work, done every four to five years, will result in the shutdown of
one of the company's two oil sands upgraders. Production at the oil sands
operation is expected to average 110,000 barrels per day during the maintenance
period.
--------------------------------------------------------------------------------------------------------------------


Factors that could potentially impact the first quarter, 2003 include:

/ /  Suncor's future financial performance is closely linked to oil and natural
     gas prices and exchange factors. Volatility may impact results. The
     volatility in natural gas prices can also impact the costs of Suncor's Oil
     Sands and Energy Marketing and Refining segments.

/ /  Extreme cold weather, which can have an impact on oil sands mining,
     upgrading and transportation of products, is possible in the first quarter.

/ /  Refining margins are currently between 5.3 cents per litre (cpl) and 5.5
     cpl, compared to 6.6 cpl in the fourth quarter of 2002. Retail margins are
     currently between 7.0 cpl and 7.2 cpl, compared to 6.5 cpl in the fourth
     quarter of 2002.

/ /  The realization on the crude sales basket can be impacted by Suncor's sales
     mix as well as general market conditions, which can impact differentials.


                                                                               3

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.  ACCOUNTING POLICIES

These interim consolidated financial statements have been prepared in accordance
with Canadian generally accepted accounting principles and 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 of the change in accounting with respect to the translation of Foreign
Currency discussed in note 2.

2.  CHANGE IN ACCOUNTING POLICY

Effective January 1, 2002, the company retroactively adopted the new Canadian
accounting standard for Foreign Currency Translation, and as a result, all prior
periods have been restated. This new standard applies to the company's
foreign-currency denominated preferred securities and long-term debt (see note
4). The impact of this new standard on the consolidated balance sheets and
statements of earnings is as follows:

Common share and earnings per common share amounts in the above table reflect a
two-for-one share split effective May 15, 2002.

(a) For the fourth quarter and year ended December 31, 2001, diluted earnings
per share is the net earnings attributable to common shareholders divided by the
weighted-average number of diluted common shares. Dividends on preferred
securities, the revaluation of US$ preferred securities and the redemption of
preferred securities by the issuance of common shares have an anti-dilutive
impact, therefore they are not included in the calculation of diluted earnings
per share.

(b) Basic earnings per share is the net earnings attributable to common
shareholders divided by the weighted-average number of common shares.

(c) Diluted earnings per share is the net earnings before deducting dividends on
preferred securities and revaluation of US$ preferred securities, divided by the
weighted-average number of diluted common shares.



6.  INCOME TAXES

During 2002, the Alberta government enacted legislation that resulted in a
decrease of 0.5% in the Alberta corporate income tax rate. This reduction,
combined with a deferral in the Ontario corporate income tax rate reduction,
required revaluation of the future tax balances for the company resulting in an
aggregate future income tax recovery of $10 million. (In 2001, Alberta and
Ontario rate changes resulted in an aggregate future income tax recovery of $43
million). The new rates are reflected in the tax provision for the current year.
The income tax rate changes did not affect the company's current cash flow or
liquidity.

7.  STOCK-BASED COMPENSATION

--------------------------------------------------------------------------------
A STOCK OPTION GIVES THE HOLDER THE RIGHT, BUT NOT THE OBLIGATION, TO PURCHASE
COMMON SHARES AT A PREDETERMINED PRICE OVER A SPECIFIED PERIOD OF TIME.

AFTER THE DATE OF GRANT, EMPLOYEES THAT HOLD OPTIONS MUST EARN THE RIGHTS TO
EXERCISE THEM. THIS IS DONE BY THE EMPLOYEE FULFILLING A TIME REQUIREMENT FOR
SERVICE TO THE COMPANY, AND WITH RESPECT TO CERTAIN OPTIONS, IS SUBJECT TO
ACCELERATED VESTING SHOULD THE COMPANY MEET PREDETERMINED PERFORMANCE CRITERIA.
ONCE THIS RIGHT HAS BEEN EARNED, THESE OPTIONS ARE CONSIDERED VESTED. OPTIONS
GRANTED TO NON-EMPLOYEE DIRECTORS VEST AND ARE EXERCISABLE IMMEDIATELY.

THE PREDETERMINED PRICE AT WHICH AN OPTION CAN BE EXERCISED IS EQUAL TO OR
GREATER THAN THE MARKET PRICE OF THE COMMON SHARES ON THE DATE THE OPTIONS ARE
GRANTED.

SEE BELOW FOR MORE TECHNICAL DETAILS AND NUMBERS ON THE COMPANY'S STOCK OPTION
PLANS:
--------------------------------------------------------------------------------

On April 30, 2002, the company granted 8,334,240 options to all eligible
permanent full-time and part-time employees, both executive and non-executive,
under its new employee stock option incentive plan ("SunShare"). Under SunShare,
meeting specified performance targets may accelerate the vesting of some or all
options, such that 20% of outstanding options may vest as early as 2004, up to
an additional 20% of outstanding options may vest as early as 2005 and the
remaining 60% of outstanding options may vest on April 30, 2008. All unvested
options which have not previously expired or been cancelled will automatically
vest on January 1, 2012. During 2002, in addition to the initial grant, 603,752
SunShare options were granted to new employees, of which 262,262 were granted in
the fourth quarter.

Under the company's other plans, 3,450 options were granted in the fourth
quarter of 2002 (1,805,450 options were granted during the year ended December
31, 2002). In 2001, 2,500 options were granted in the fourth quarter (2,180,720
options were granted during the year ended December 31, 2001).



The fair values of all common share options granted during the period are
estimated as at the grant date using the Black-Scholes option-pricing model. The
weighted-average fair values of the options granted during the year and the
weighted-average assumptions used in their determination are as noted below:

------------------------------------------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------------------------------------------


The company does not recognize any compensation expense related to stock options
granted to employees and non-employee directors. Had compensation expense been
determined based on the fair values at the grant dates, the cost of which is
recognized over the estimated vesting periods of the options granted, the
company's net earnings and earnings per share would have been reduced to the
amounts below:

9.  SALE OF THE RETAIL NATURAL GAS MARKETING BUSINESS

Effective May 2, 2002, the company sold its retail natural gas marketing
business in the Energy Marketing and Refining segment for proceeds of $62
million, net of related closing costs and adjustments of $4 million. The pre-tax
earnings impact of the sale was $38 million ($35 million after-tax). Proceeds
from the sale decreased cash used in investing activities.

10. GOODWILL

Effective January 1, 2002, the company adopted the new Canadian accounting
standard for Goodwill and Other Intangible Assets. Accordingly, goodwill is no
longer amortized to earnings but periodically tested for impairment. As at
December 31, 2002, the annual assessment of goodwill impairment has been
completed and no reduction of the carrying value of $14 million was required.
Excluding goodwill amortization from prior period results does not significantly
impact net earnings or earnings per share.
