On July 20, 2026, President Trump announced 50% tariffs on a wide range of Canadian goods under Section 338 of the Trade Act of 1930. The measures target Canadian barriers on automobiles, alcohol, and dairy while exempting energy, potash, fish, and critical minerals, and apply to items previously covered by the expired USMCA. Canada had previously retaliated against earlier U.S. tariffs, and the administration is also examining tariffs linked to Canadian wildfires.
