The US already gets the majority of its oil imports from Canada (52.5%).
(And the US also exports oil to Canada.)
I imagine there will be an adjustment in imports/exports as each country needs more of its own oil.
Of the 7.86 million barrels per day the U.S. imported in 2020, the majority came from its North American neighbors: Canada, with 4.13 million barrels (52.5%), and Mexico, with 750,000 (9.6%).
But imports coming from outside North America are significant. Russia, with 540,000 barrels a day (6.6%), was the top non-continental contributor. Roughly 11% of the imports came collectively from OPEC countries, including 520,000 from Saudi Arabia.
But the U.S. exports petroleum, too – and in 2020, for the first time
since 1949, the U.S. exported more than it imported – 635,000 barrels per day more.
Of the 8.5 million barrels per day exported in 2020, Mexico and Canada reappear as the largest partners again, each receiving about a million barrels per day from the U.S. China was the third-largest recipient, with 720,000 barrels a day. Japan and India round out the top five, receiving about half a million barrels per day each.
