Trump Uses Obscure 1930 Trade Law to Impose 50% Tariffs on Canadian Goods

Trump imposed 50% tariffs — import taxes — on $20 billion in Canadian dairy, autos, and alcohol, invoking Section 338 of the Trade Act of 1930 for the first time on record. The provision has no legal precedent, meaning Canada lacks an established pathway to challenge the move under current trade agreements. The tariffs take effect August 2026.
