Trump’s rhetoric on Canada, such as calling for it to become a U.S. state, had softened after Prime Minister Mark Carney replaced Justin Trudeau in an election last April. But it’s ramped up again since October, when Ontario Premier Doug Ford ran ads in the U.S. quoting former President Ronald Reagan against tariffs. Trump terminated trade talks as a result, leaving in place large tariffs on key Canadian exports to the U.S. like aluminum, steel and autos, as well as a 35 per cent tariff on the small amount of trade not covered by USMCA.
