Canada imposes $20 billion in counter-tariffs on U.S. goods Sept. 8

Canada will impose retaliatory tariffs — taxes on imports — on $20 billion of U.S. goods starting September 8, 2026, after trade talks collapsed. The countermeasures add duties of 15, 25 and 50 per cent across roughly 700 American products. They respond to 50 per cent U.S. tariffs on Canadian exports imposed when negotiations failed last month.
