The US just lobbed a $20 billion tariff grenade at Canada, and so far, Ottawa is choosing not to throw one back.
What exactly happened
US Trade Representative Jamieson Greer invoked Section 338 of the Tariff Act of 1930 to justify new 50% levies on Canadian imports, citing what he called ongoing discriminatory practices by Canada. The specific grievances are colorful: Canadian provinces pulling US alcohol from store shelves, and preferential treatment for European dairy imports over American ones. The tariffs cover roughly $20 billion in Canadian goods across motor vehicles, alcoholic beverages, and dairy products, and will take effect 30 days from the July 20, 2026 announcement.
The US has apparently been asking Canada to roll back its own retaliatory measures for over a year. Greer framed these tariffs not as an opening salvo but as a response to Canadian actions that the US considers unfair within the context of the ongoing USMCA renegotiations. Canada has not indicated any plans to retaliate.
