Based on the latest annual data from the U.S. Census Bureau, energy accounted for $18 billion, or about 6%, of the value of all U.S. exports to Canada. Energy accounted for $73 billion, or about 24%, of the value of all U.S. imports from Canada in 2017, up from 19% in 2016. Canada is the main source of U.S. energy imports and the second-largest destination for U.S. energy exports behind only Mexico.
Crude oil accounts for most U.S. energy imports from Canada, averaging 3.4 million barrels per day (b/d) in 2017. Canada is the largest source of U.S. crude oil imports, providing 43% of total U.S. crude oil imports in 2017. The value of U.S. crude oil imports depends on both volume and price. In 2017, the value of U.S. imports of Canadian crude oil increased, reaching $50 billion, as a result of both an increase in oil prices and an increase in volume. Canadian crude oil imported by the U.S. is largely produced in Alberta and consists mainly of heavy grades shipped primarily to the Midwest and Gulf Coast regions.
