Trump Increases Canada Tariffs 10% Over Anti-Tariff Reagan Ad Dispute

President Donald Trump has escalated trade tensions with Canada by announcing a 10% increase in tariffs on Canadian imports following a controversial Ontario provincial ad campaign. The ad used selective audio from former President Ronald Reagan's 1987 radio address to criticize tariffs, which Trump claimed misrepresented Reagan's stance and was created using artificial intelligence without permission. Despite Ontario Premier Doug Ford's decision to pull the ad after the weekend, it aired during the World Series, further angering Trump. Trump accused Canada of a "fraudulent advertisement" intended to influence U.S. Supreme Court decisions on tariffs and justified the tariff hike as a defense against "high and overbearing Canadian Tariffs." The tariff increase comes after Trump abruptly ended trade negotiations with Canada, signaling a significant deterioration in U.S.-Canada trade relations amid ongoing disputes over tariffs. The situation remains tense as Canadian officials attempt to negotiate, with Canada heavily reliant on the U.S. market for exports and already facing substantial tariffs on various goods.
