Canada announced retaliatory tariffs on approximately 20 billion dollars worth of US goods on Tuesday, matching President Donald Trump’s new 50% import duties dollar for dollar in the sharpest escalation of the North American trade war to date.
Finance Minister Francois-Philippe Champagne confirmed the countermeasures from Ottawa, saying Canada would impose tariffs of 15%, 25%, and 50% on products across categories targeted by US Section 338 and Section 232 tariffs. The tariffs take effect September 8 and cover more than 700 American products.
Steel and aluminum face the steepest 50% rate. Appliances, dairy products including cheese, fish and seafood, and certain steel derivatives carry a 25% duty. Other goods fall under a 15% rate. The categories named include steel, dairy, agricultural equipment, farm machinery, pulp and paper, and electronics.
How We Got Here
The trade battle accelerated on July 20 when Trump signed three proclamations invoking Section 338 of the Tariff Act of 1930, a rarely used statute that allows the President to impose duties of up to 50% on goods from a country found to discriminate against US commerce. No president had used Section 338 this way before.
The tariffs targeted Canadian automobiles, alcohol, and dairy products, citing provincial liquor board restrictions and Canada’s supply-management dairy system. A three-day pause was granted on August 19 while negotiators tried to reach a broader deal. Those talks collapsed, Prime Minister Mark Carney recalled Canada’s negotiating team, and the 50% tariff took effect as scheduled at 12:01 a.m. ET on August 22.
Trump’s tariffs apply to covered Canadian goods regardless of whether they qualify for USMCA preferential treatment, a detail that has caught many importers off guard. Energy products, potash, fish, and critical minerals are excluded.
What It Means for Businesses
Canada also announced 7.5 billion Canadian dollars in support for workers and businesses affected by the tariffs. The package includes measures for industries hit hardest by the trade disruption, though specific program details were still being finalized.
Ontario Premier Doug Ford backed Carney’s response. On the US side, economists have warned the tariffs could rattle economies in states with key Senate races ahead of the 2026 midterms. The US had already imposed a 50% tariff on 27.6 billion dollars of Canadian goods effective August 22, and the two countries now face mutual high tariffs on a broad range of bilateral trade.
