Trump Plays Hardball With Canada

President Trump has invoked a Depression-era trade statute to impose sweeping 50% tariffs on Canadian dairy, alcohol, and automobiles, directly challenging Canada's protectionist Supply Management system. The unprecedented use of Section 338 of the Tariff Act of 1930 signals an aggressive push for major concessions on agricultural trade barriers as CUSMA negotiations intensify.
