Trump wants to impose tariffs on Canada in retaliation for wildfire smoke

President Donald Trump on Friday threatened to impose tariffs on Canada in retaliation for wildfire smoke, but it was not clear that he has the legal authority to impose such a levy.

The White House did not respond to questions about what legal mechanism he would use to impose the tariffs or how the administration would calculate the rate of the levies. Trump wrote in a Truth Social post that the cost of the pollution was “incalculable.”
