In a post on X, formerly Twitter, following Trump's announcement Ontario Premier Ford wrote: "A 25 per cent tariff would be devastating to workers and jobs in both Canada and the U.S. The federal government needs to take the situation at our border seriously."

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.

Mexico and Canada are the United States’ top two trading partners, accounting for nearly 30% of trade volumes.
