U.S. President Donald Trump has abruptly canceled all ongoing and future trade talks with Canada, citing a recent advertisement that featured former President Ronald Reagan criticizing tariffs. Trump announced the decision on Truth Social, calling Canada’s actions “disgraceful.” The move marks a sharp escalation in tensions between the two nations, which are major trading partners. During his previous term, Trump had imposed a 35% tariff on Canadian imports, with exemptions for products under the USMCA—his landmark free trade deal with Mexico and Canada. He also levied 50% tariffs on metals and 25% on automobiles imported from Canada. This latest decision threatens to destabilize North American trade relations and could have significant economic repercussions for both sides if maintained in the long term.
