President Donald Trump on Monday (August 24, 2026) threatened to impose a 50% tariff on Canadian automobiles, car parts, and steel starting next year as the trade rift with Ottawa continued to deepen.

The announcement comes after trade talks between otherwise allies and reliable trading partners collapsed last week.

Long-planned U.S. tariffs on various Canadian goods went into effect after the talks broke off, and Canada has vowed to retaliate.

“Canada has been ripping off the United States of America for years,” Mr. Trump wrote on social media on Monday (August 24) morning.

Criticising Canada’s “ridiculously high tariffs” on American farmers, Mr. Trump wrote: “Not sustainable, and NOT ANYMORE!”
