Overview
- Late Friday, negotiations between Ottawa and Washington collapsed and the White House imposed 50% tariffs under Section 338 of the Tariff Act of 1930 that took effect at midnight on roughly $20–28 billion of Canadian goods.
- Prime Minister Mark Carney suspended talks, ordered Canadian negotiators home and vowed to match U.S. duties dollar for dollar while preparing financial support for affected firms and workers.
- The new levies target a wide range of products — including wine, dairy, clothing, cement, hockey equipment and some industrial inputs — and add to earlier U.S. tariffs on steel, aluminum, autos and lumber.
- The use of Section 338, a seldom‑used Depression‑era authority, makes court challenges likely and raises short‑term risks to tightly integrated North American supply chains and to cooperation under the USMCA framework.
- A key flash point was provincial bans on U.S. alcohol sales that Ottawa cannot unilaterally remove, and premiers are split on concessions, which complicates any quick deal and pushes Canada to seek market diversification over time.
