“the U.S. is heavily reliant on Canadian crude oil to make liquid fuels and other petroleum products. Most U.S. refineries were built in the 1970s to accommodate heavy oil from the Middle East and Canada. This was well before the American shale boom, which brought lighter-grade oil to the market. In 2023, nearly 60 percent of crude imports came from Canada and July 2024 saw a record 4.3 million barrels of oil per day imported from the country.
“Canada is by far our largest supplier, and we build refineries specifically to refine heavier Canadian crude,” explains Nick Loris, the executive vice president of policy at C3 Solutions, a free market energy think tank. “Depending on the tariff rate and how long they’re in place, gas prices could rise anywhere from 10-30 cents per gallon, with the Midwest and the Rocky Mountain Region getting hit the hardest,” Loris tells Reason.”

“tariffs could also harm American nuclear power. Despite generating the most nuclear energy in the world, the U.S. relies on other nations for uranium to fuel its fleet. Canada is the largest supplier of raw uranium (27 percent of imports in 2022), followed by Kazakhstan (25 percent) and Russia (12 percent), the latter of which the U.S. depends on for roughly a quarter of its uranium enrichment needs.
With last year’s passage of a bill to ban imports of Russian uranium signed into law, Canada is primed to play an increasingly important role in America’s uranium supply. Tariffs would threaten this and could increase fuel costs for American nuclear power producers”
