Suncor Energy is a Canadian integrated energy company based in Calgary, Alberta. It specializes in production of synthetic crude from oil sands.

In the 2020 Forbes Global 2000, Suncor Energy was ranked as the 252nd-largest public company in the world.

Until 2010, Suncor marketed products and services to retail customers in Ontario through a downstream network of 280 company-owned, and 200 customer-operated retail and Diesel fuel sites, primarily in Ontario under the Sunoco brand (owing to Suncor having originally been established as a subsidiary of Sunoco).

In 2009, Suncor acquired the former Crown corporation Petro-Canada, which replaced the Sunoco brand across its existing outlets. Suncor also markets through a retail network of Shell and ExxonMobil branded outlets in Colorado.
