President Trump on Tuesday imposed new retaliatory tariffs on Canada and insisted the only solution was for the country to join the U.S. — but then reversed his decision after Ontario agreed not to levy electricity exports.
Why it matters: The pullback was the latest example of the on-again, off-again volatility that has disrupted financial markets.
The latest: A 25% tariff on all steel and aluminum imported into the U.S. that economists warn could hurt Americans took effect Wednesday morning.
The big picture: Close allies less than two months ago, relations between the U.S. and Canada have now frayed to the point that diplomacy is being conducted by furious TV appearances and social media name-calling.
Catch up quick: Trump, in a Truth Social post Tuesday morning, said steel and aluminum tariffs on Canada, already scheduled for Wednesday, would now be 50% instead of 25%.
Between the lines: Ontario Premier Doug Ford posted to X that he would meet with Commerce Secretary Howard Lutnick on Thursday to discuss trade issues, and in the meantime would suspend a tariff on electricity coming into the U.S.
Canada is by far the largest source of U.S. electricity imports, per EIA data, though those imports account for less than 1% of U.S. consumption.
What they're saying: Canada's incoming prime minister, former central bank head Mark Carney, promised a response that maximized the impact on the U.S.
