Imposes new 50% tariffs on $20 billion worth of Canadian products

President Donald Trump announced new 50% tariffs on imports from Canada on Monday, framing the move as retaliation for what the U.S. administration called discriminatory treatment of U.S.-made cars, alcohol, and dairy. Using Section 338 of the Tariff Act of 1930, the White House said the measure allows punitive duties of up to 50% against trading partners deemed to discriminate. The tariffs, set to start in 30 days, would cover roughly $20 billion of Canadian imports, about 5.2% of the $382 billion the U.S. bought from Canada in 2025. Canada’s Prime Minister Mark Carney said the government has proposals to resolve disputes and argued the tariffs violated the North American trade pact. U.S. Trade Representative Jamieson Greer said Canada retaliates in national-security sensitive sectors and noted ongoing talks under USMCA in Mexico City.
