In September 2025, U.S. President Donald Trump imposed new tariffs and bans on Canadian imports as part of an escalating trade war between the two nations. The measures included a 50% tariff on goods like metal and paper products, representing about 0.6% of total U.S. imports from Canada, while lifting tariffs on items such as salt, cement, and toilet paper. Trump also banned Canadian alcoholic drinks, whey, molasses, furniture, and other products effective September 29. In retaliation for these actions, Canada imposed its own tariffs on about $20 billion worth of American goods in October. These moves have prompted China to court Canada more closely, with Prime Minister Mark Carney making state visits to China and India to diversify trade relations. The legal validity of Trump's tariff measures under Section 338 is being challenged based on the major questions doctrine, which limits executive overreach without clear statutory authorization.
