Canada Invokes CUSMA Retaliation Clause with $51 Billion in Countervailing Tariffs

Canadian Prime Minister Mark Carney formally invokes the retaliation clause of the Canada-United States-Mexico Agreement in response to U.S. tariffs, announcing $51 billion Canadian dollars in countervailing tariffs on American goods. The move marks the most significant trade escalation between the two countries since CUSMA was enacted. Targeted sectors include American steel, aluminum, and agricultural products, threatening jobs in U.S. manufacturing and farm states.
