U.S. and Canada impose 50% tariffs as trade talks collapse
After negotiations fell apart, the United States and Canada each announced 50% tariffs on $20 billion worth of each other's goods, reviving a rarely used provision of the 1930 Smoot-Hawley Act.
The United States and Canada entered a reciprocal tariff regime on Aug. 25-26, 2026, after trade talks stalled. Washington imposed a 50% duty on $20 billion of Canadian exports, including auto parts, forestry products, furniture, textiles, whiskey and hockey equipment, invoking Section 338 of the Tariff Act of 1930. Canada responded with matching tariffs of up to 50% on a comparable $20 billion of U.S. imports such as Wisconsin cheese, Maine seafood and Kentucky appliances.
The move marks the first use of the Smoot-Hawley provision that allows the president to levy unilateral tariffs when a foreign country is deemed to discriminate against U.S. goods. Economists note that the original 1930 tariffs deepened the Great Depression by triggering retaliatory measures.
Negotiations had focused on reducing U.S. duties on Canadian steel, aluminum and automobiles. According to sources, U.S. Commerce Secretary Howard Lutnick, under pressure from domestic metal producers, rejected proposed cuts, prompting Canada to withdraw its offer to reopen the Keystone oil pipeline agreement and to abandon a request that Canada reverse provincial bans on U.S. liquor.
"Canada is one of the worst countries in the world to deal with," President Donald Trump said after the tariffs were announced.
Prime Minister Mark Carney accused Trump of trying to "destroy" Canada's auto industry.
Both governments argue the tariffs are a response to perceived unfair treatment, but analysts warn that the 50% duties will raise prices for U.S. consumers and businesses that rely on cross-border supply chains, particularly in border states such as Michigan, New York, Pennsylvania, Ohio, Wisconsin and Maine. The tariffs also risk influencing upcoming midterm elections in swing states that are sensitive to trade-related price changes.
While the overall impact on U.S. inflation may be limited, the combined duties could significantly affect sectors with high bilateral trade volumes, including automotive parts, seafood, and agricultural products. The dispute revives a trade tool designed to prevent, not provoke, trade wars, raising concerns about a broader escalation.
