Yes. Canada’s retaliatory tariffs on a range of U.S. goods took effect on Tuesday, Sept. 8, 2026, covering nearly C$28 billion (about $20 billion) of American products at rates as high as 50%.
The “dollar-for-dollar” counter-tariffs apply to hundreds of items, including 50% duties on products such as U.S. milk, steel, aluminum, and some clothing, and 25% on cheese, toilet paper, and certain household appliances. Fresh fish and lobster were later dropped from the list after pushback from Canada’s seafood industry. Trade talks with the U.S. collapsed in late August, and neither side has resumed negotiations.
