Catenaa, Friday, October 24, 2025- US President Donald Trump has halted all trade negotiations with Canada after a Canadian advertisement against his tariff plan.
“TARIFFS ARE VERY IMPORTANT TO THE NATIONAL SECURITY, AND ECONOMY, OF THE U.S.A.,” Trump wrote on his Truth Social platform. “Based on their egregious behavior, ALL TRADE NEGOTIATIONS WITH CANADA ARE HEREBY TERMINATED.”
The ad in question comprises excerpts from an address former President Ronald Reagan gave in 1987 in which he defended the principles of free trade and slammed tariffs as an outdated idea that stifles innovation, drives up prices, and hurts US workers.
Funded by the government of Ontario, the ad seeks to sow doubt among Republican voters by using one of the party’s most iconic voices.
Trump, however, said the move appears timed to interfere with a looming Supreme Court case challenging the legality of much of his signature foreign economic policy.
Trump has warned of disaster if the high court overturns his country-based tariffs, including forcing the government to refund companies billions of dollars in already-paid duties.
The court is scheduled to hear oral arguments in the case on November 5.
Trump’s anger over the ad continued into Friday morning with a new series of Truth Social posts. “Canada is trying to illegally influence the United States Supreme Court in one of the most important rulings in the history of our Country,” he wrote in one.
Canada’s economy has been badly damaged by Trump’s tariffs, as about three-quarters of its exported goods went to the US last year.
Ontario, which has about 16 million people, has been at the center of the trade war because it’s the heart of Canada’s steel and automotive industries, two sectors in which Trump has hit foreign producers. Canada is the second-largest trading partner for the US.
