Canada will impose new retaliatory tariffs on $27.6 billion of US goods beginning September 8, 2026, at 12:01 a.m. The new measures respond to the United States’ 50% Section 338 tariffs on Canadian goods.

The new Canadian counter-tariffs will apply at rates of 15%, 25%, or 50%, depending on the product. Canada says the measures are designed to match the applicable US tariffs.
