Canada retaliatory tariffs: matches US 50% duties on $20B exports

Canada’s Prime Minister Mark Carney announced retaliatory tariffs after the US imposed 50% duties on about $20 billion of Canadian exports. The US tariffs took effect on August 22 and target Canadian wine, furniture, and dairy. Canada’s response is dollar-for-dollar retaliation. It will impose matching tariffs on US steel, appliances, and other sectors starting September 8, giving businesses roughly two weeks to prepare. Carney said the US demands amount to an assault on Canadian sovereignty. The tariff escalation follows the collapse of trade negotiations between Ottawa and Washington. Carney argued that US proposals are incompatible with Canadian sovereignty and regional cultural interests, not just trade calculations. The affected Canadian exports account for about 5.5% of total Canadian exports to the US. Carney also said the government will announce support measures for workers and businesses in the coming week, with relief potentially lasting for several years. The US cited Canadian policies in dairy, alcohol, and motor vehicles. In dairy, Canada’s supply management system uses quotas and high import barriers, a long-running irritant in bilateral trade. This dispute has deep roots. The current round traces back to 2025 when the Trump administration imposed tariffs over trade deficits and alleged unfair Canadian practices. Canada retaliated with 25% tariffs on $30 billion of US imports. Ottawa has since signed more than 20 trade and security deals since 2025 to reduce dependence on the US, and nearly 70% of Canadian exports still flow to the border.
