President Donald Trump said Thursday that he was terminating trade talks with Canada, effective immediately.

Trump accused Canada of trying to interfere with an upcoming Supreme Court case about the legality of his "reciprocal" tariffs.

Trump made the announcement on Truth Social after the Canadian province of Ontario began running a television advertisement in the United States featuring a speech from former President Ronald Reagan.

“They only did this to interfere with the decision of the U.S. Supreme Court, and other courts,” Trump wrote, referring to the high court’s scheduled Nov. 5 oral arguments on legal challenges to a significant part of Trump’s tariffs. They include the country-specific rates at the heart of both his foreign policy and economic agendas.

Canadian Prime Minister Mark Carney told reporters Friday that his government stands ready to advance previously fruitful trade talks and "build on that progress when the Americans are ready to have those discussions."

The ad, which Ontario's premier, Doug Ford, posted on X, begins with Reagan saying, "When someone says, 'Let’s impose tariffs on foreign imports,' it looks like they’re doing the patriotic thing by protecting American products and jobs, and sometimes for a short while it works, but only for a short time."
