Canada Unveils Retaliatory Tariffs on US$20 Billion of U.S. Goods

Canada will strike back against newly imposed U.S. duties, Prime Minister Mark Carney said, announcing retaliatory tariffs designed to mirror the 50% levies Washington has placed on roughly US$20 billion of Canadian exports. Carney called the U.S. demands an assault on Canadian sovereignty. The U.S. tariffs took effect Aug. 22 and apply to Canadian wine, furniture and dairy products. Canada's countermeasures will begin Sept. 8 and target U.S. steel, home appliances and additional categories, giving companies about two weeks to prepare. The escalation follows a breakdown in trade talks between Ottawa and Washington. Carney said U.S. proposals were fundamentally incompatible with Canadian sovereignty and regional cultural interests. The Canadian exports affected by the U.S. action account for about 5.5% of Canada's total exports to the United States. Carney said the government will outline support for impacted workers and businesses in the coming week, and indicated the relief package could span several years. Washington cited Canadian practices in dairy, alcohol and motor vehicles to justify the tariffs. Canada's dairy supply-management system—built on quotas and high import barriers to protect domestic farmers—has long been a source of friction in bilateral trade relations. The latest round of tensions traces back to 2025, when the Trump administration imposed tariffs citing trade deficits and what it described as unfair Canadian practices. Canada responded with retaliatory measures, including 25% tariffs on US$30 billion of U.S. imports. Ottawa has also sought to reduce reliance on the U.S. market, signing more than 20 new trade and security agreements since 2025. Nearly 70% of Canadian exports still go to the United States.
