Oil Sands

Suncor’s Oil Sands business, with assets located in the Athabasca oil sands of northeast Alberta, recovers bitumen from mining and in situ operations. Bitumen is either upgraded into synthetic crude oil (SCO) for refinery feedstock and diesel fuel or blended with diluent for direct sale to market through the company’s midstream infrastructure and its marketing activities.

Exploration and Production

Suncor’s Exploration and Production (E&P) segment consists of offshore operations located off the east coast of Canada as well as in the North Sea (the U.K. and Norway), and onshore assets in Libya and Syria. Due to political unrest, production in Libya remains partially shut-in and operations in Syria have been suspended indefinitely.

Refining and Marketing

The Refining and Marketing segment consists of two primary operations, the Refining and Logistics (R&L) and marketing operations, as well as the infrastructure supporting the marketing and supply of refined products, crude oil, natural gas, power and byproducts. R&L operations refine crude oil and intermediate feedstock into a wide range of petroleum and petrochemical products at our four refineries located in Edmonton, Alta.; Sarnia, Ont.; Montreal, Que. and Commerce City, Colo.

Marketing operations sell refined petroleum products to retail, commercial and industrial customers through the more than 1,850 Petro-Canada™ branded retail and wholesale sites in Canada and other non-branded retail stations in the U.S. The Canadian network is supported by a nationwide commercial road transportation network and bulk sales channel.


Wind power

Renewable energy includes interests in four wind farm operations in Ontario and Western Canada.

Our wind power facilities located in Alberta, Saskatchewan and Ontario have a gross generating capacity of 111 megawatts (MW), enough to power about 52,000 homes and to avoid approximately 179,000 tonnes of CO2 per year.

Adelaide Wind Power Project

In support of Suncor’s social goal, we continue to create additional economic opportunities for Indigenous groups through both service provision and equity partnership opportunities. The jointly-owned Adelaide Wind Power Project in southern Ontario has contributed to a positive working relationship between Suncor and Aamjiwnaang First Nation.

St. Clair ethanol plant

Suncor operates Canada's largest ethanol facility – the St. Clair ethanol plant in the Sarnia-Lambton region of Ontario. The St. Clair ethanol plant has a current production capacity of 400 million litres per year. The ethanol produced here is blended into Petro-Canada™ gasoline.

The plant currently uses 40 million bushels of corn annually, approximately 20% of Ontario's annual corn crop. The type of corn used as feedstock has traditionally been used to feed livestock. Once the starches are extracted from the corn to make ethanol, the remaining elements are used to make premium cattle feed.
