U.S. Tariffs on Canada

As of August 1, 2025, the United States (U.S.) imposed tariffs of up to 35 per cent on Canadian goods that do not comply with the Canada–United States–Mexico Agreement (CUSMA). Tariffs of approximately 10 per cent apply to certain energy and potash products, while steel and aluminum remain subject to significantly higher U.S. tariffs.

Canada’s counter-tariffs on steel, aluminum and automobiles remain in effect. However, in recognition of the U.S. approach to allow most Canadian goods to enter the U.S. tariff-free under CUSMA, Canada removed most counter-tariffs that were introduced in March 2025 on U.S. imports, effective September 1, 2025.

Today, the vast majority of Canadian exports continue to enter the U.S. market tariff-free when they meet CUSMA requirements.
