Canada announced retaliatory tariffs on US imports starting September 8 after trade talks between Ottawa and Washington collapsed and President Donald Trump imposed 50 percent duties on $20 billion worth of Canadian products.
Prime Minister Mark Carney said from Parliament Hill that Canada would match the US tariffs dollar for dollar on US steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. The move came just hours after the Trump administration began enforcing its new tariffs under Section 338 of the Tariff Act of 1930, a law no president had previously invoked.
Trade Talks Collapse Over New 50 Percent Levies
Trump tariffs target wine, furniture, dairy, cement, clothing, fishing rods and hockey equipment, covering roughly 5 percent of Canadas total exports to the US. The levies apply to both USMCA-compliant and non-compliant goods, a departure from earlier rounds of tariffs that exempted products meeting the trade agreements rules of origin.
Carney called the tariffs a miscalculation and said Canada had agreed to drop most of its own retaliatory duties on US goods just weeks earlier as a goodwill gesture to restart stalled negotiations. That concession, which took effect August 1, removed tariffs on thousands of American products while keeping 25 percent duties on US steel, aluminum and automobiles.
Canada will match those tariffs dollar for dollar, Carney said from Ottawas Parliament building. This is a miscalculation by the US administration.
Impact on Key Sectors
Trade experts warned that the new US tariffs could expose vulnerable Canadian industries, particularly softwood lumber and wine, to severe damage and trigger job losses and business closures. The tariffs represent the most significant escalation since Trump imposed blanket 25 percent duties on all Canadian goods in February 2025.
The collapse of talks also raises uncertainty around the broader USMCA review process, which is scheduled to begin in 2026. Canada had been positioning itself for the review by demonstrating willingness to negotiate, including scrapping a proposed digital services tax on US tech companies in June and delaying additional retaliatory measures.
Broader Trade War Fallout
The dispute adds to a growing list of US trade conflicts. Washington has also imposed 50 percent tariffs on Chinese goods and raised duties on imports from dozens of other countries. Canadas retaliatory measures, while narrower in scope than its earlier 155 billion dollar tariff package, signal that Ottawa is prepared for a prolonged confrontation.
Canadian finance officials said they are monitoring the situation and considering further non-tariff measures in coordination with provincial governments.
