Suncor Energy Inc. is Canada’s Wal-Mart Stores: the country’s biggest corporation by revenue. Founded in 1919 as a subsidiary of what eventually became Sunoco Inc., Suncor is probably the most responsible and environmentally friendly company developing the Athabasca tar sands, anarea of crude oil deposits in northern Alberta the size of New York State. Athabasca potentially holds trillions of barrels of petroleum and that could supply black gold for centuries.
Suncor also has upstream, midstream, and downstream oil operations, with four high-capacity refineries and over 1’500 petrol stations across Canada under the Petro-Canada brand. The economic value of the Suncor’s mining and is estimated at tens of billions of dollars, which should keep the company at or near the top of this list of top Canadian oil companies for the next few decades.
