U.S. Imposes 50% Tariffs on Canadian Goods as Canada Vows Dollar-for-Dollar Retaliation

The measures took effect Saturday, threatening integrated auto and metals supply chains, higher consumer prices, legal fights, longer-term strain in the U.S.-Canada trade relationship.

Overview

  • The United States put 50% duties on roughly $20 billion of Canadian exports that took effect Saturday under Section 338 of the Tariff Act of 1930, a rarely used presidential authority that allows immediate duties up to 50 percent.
  • Canada has pledged dollar-for-dollar retaliatory tariffs that Ottawa says will begin on Sept. 8 and is preparing domestic aid for affected workers and businesses.
  • President Trump announced a further threat to raise tariffs on cars, trucks, auto parts and steel to 50% starting Jan. 1, 2027, and the administration has paused immediate new talks with Canada.
  • Reporting from people familiar with the negotiations says U.S. Commerce Secretary Howard Lutnick applied last-minute pressure for tougher terms, which Canadian officials say helped collapse the deal and both sides publicly blame the other for the breakdown.
  • Governors and lawmakers in both countries warn the levies will raise costs for consumers and disrupt cross-border supply chains, while officials on each side prepare legal challenges and efforts to diversify trade links beyond the other country.
