Canada-U.S. Trade War: Talks collapsed and the U.S. moved first, imposing 50% tariffs on about $20B of Canadian goods, including hockey gear and liquor, with Canada’s PM Mark Carney calling it an “attack” and ordering “dollar-for-dollar” retaliation starting Sept. 8. Retaliation Targets: Ottawa says its counter-tariffs will hit U.S. sectors such as steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics, while Washington escalated rhetoric by claiming Canada wants “the benefits of being a State, without being one.” Political Pressure in Canada: Conservatives are demanding the federal government release the full text of the U.S. offer that Canada walked away from, arguing Canadians and Parliament deserve specifics. Business Fallout: Canadian firms and small businesses are already recalculating costs and suppliers, and economists warn the longer the fight lasts, the more jobs and inflation pressure could follow. Regional Response: Eastern premiers renewed “buy local” calls as the tariff fight ramps up. Broader Context: The breakdown also raised questions about how far U.S. leverage can go in shaping Canada’s trade deals with other countries.
