The Government of Canada has announced a new round of counter-tariffs in response to recent U.S. Section 338 tariff measures on Canadian exports.

Effective September 8, 2026, Canada will impose additional tariffs of 15%, 25%, and 50% on selected U.S.-origin goods representing approximately $27.6 billion in imports. Affected product categories include steel, dairy products, appliances, agricultural equipment, pulp and paper products, electronics, and other commodities.

The tariffs will apply only to goods that qualify as U.S.-origin under Canada-United States-Mexico Agreement (CUSMA) marking rules. Goods that are already in transit to Canada before September 8, 2026, will not be subject to the new tariffs.

Companies importing affected U.S. products could be eligible for support through programs administered by the Canadian Department of Finance, including the Regional Tariff Response Initiative, the Canada Strong Diversification Fund, or several other relief and remission measures.
