The National Post reports in its Thursday edition that since April 9, 2025, Canada has imposed a 25-per-cent tariff on non-USMCA-compliant U.S.-made vehicles. The Post's guest columnist Peter Navarro writes that even qualifying vehicles are taxed on the value of components not originating in Canada or Mexico. No comparable tariff applies to vehicles from Japan, Korea, Germany or other competitors. Comparing April, 2025, through March, 2026, with the preceding year, U.S. vehicle exports to Canada fell about 22 per cent, from roughly $25.9-billion to $20.3-billion. Canadian imports from Mexico rose 23.6 per cent, while imports from Japan, Korea, and Germany also increased. That is industrial discrimination: penalize the American vehicle, reward the foreign substitute. Ottawa will claim these actions retaliated against U.S. tariffs, but that overlooks legal and economic aspects. U.S. Section 232 auto tariffs are based on national security and favour American content, while Canada's system discriminates against U.S. commerce and favours other foreign trade. Section 338 was written for such conduct. Free trade cannot mean Canada is free to sell while America is forbidden to compete. The era of one-way concessions is over.
