Canada is a main source of crude oil imports and industrial supplies like steel for the United States. More than 71% of U.S. crude oil imports were supplied by Canada and Mexico in 2023, according to a new report from the Congressional Budget Office (CBO). Of that share, 60% of oil came from Canada.

The leader of Ontario said he will be calling an election next week because he needs a mandate to fight Trump's threatened tariffs.

Trump said in an Oval Office signing ceremony on Monday that his administration will impose a 25% tax on goods from Canada and Mexico that may come as soon as February 1 – a move that could raise prices for American consumers.
