Trump Plans Additional 10% Tariff on Canadian Imports Over Ontario Anti-Tariff Ad

President Donald Trump announced a plan to increase tariffs on Canadian imports by an additional 10% in response to an anti-tariff television advertisement aired by Ontario, which used quotes from former President Ronald Reagan to criticize U.S. tariffs. Trump accused the Ontario government of serious misrepresentation and a hostile act, expressing frustration that the ad was not removed immediately and aired during the World Series. Ontario Premier Doug Ford stated the ad would be pulled after the weekend, but Trump declared an end to trade discussions with Canada and said he had no intention of meeting Canadian Prime Minister Mark Carney at the upcoming ASEAN summit in Malaysia. Existing tariffs have already impacted Canada's economy significantly, with some products facing rates as high as 50%, while others remain exempt under the US-Canada-Mexico Agreement, which is under review. The timing and scope of the new 10% tariff increase remain unclear, adding further uncertainty to the strained trade relations between the U.S. and Canada.
