In 2025, Canada imported 19.1 million metric tons of crude oil from the United States, which was the largest quantity Canada imported from any country. The U.S. is also Canada's most important trading partner when it comes to exporting its domestically produced crude. 

Canadian crude oil

In 1858, the first oil deposit in North America was found in Ontario, Canada. Today, however, Canada’s largest crude oil production sites are in Alberta. Although Canada is a net exporter of crude oil, Canada also imports crude oil, as the majority of its crude production is heavy, bitumous oil. 

History of crude oil and its uses

The beginning of the developed oil industry can be traced back to 1837 in Baku, Azerbaijan, where the first oil refinery was created. Seven years later, came the first modern oil well. This oil well accounted for more than 90 percent of the world’s oil production. More commercial oil wells were gradually developed in Poland, Romania, Canada, and the United States. The first major oil company was the Standard Oil Company, created by John. D. Rockefeller. Crude oil is refined into petroleum products, which are then used as transportation fuels, to heat homes, and produce other chemical products such as plastics.
