Overview
- President Trump signed three proclamations on Monday to impose tariffs of up to 50 percent on many Canadian goods, with the duties scheduled to take effect in 30 days.
- The administration invoked Section 338 of the Tariff Act of 1930 as the legal basis for the measures, a rarely used authority that legal experts say is untested and likely to prompt litigation.
- U.S. officials estimate the tariffs will apply to about $20 billion of Canadian imports, roughly 5.2 percent of 2025 U.S. imports from Canada, while exempting energy, potash, fish and critical minerals.
- Canadian Prime Minister Mark Carney said Ottawa is ready to negotiate but indicated Canada could pursue countermeasures if talks do not resolve the dispute.
- Analysts and business groups warn the duties could raise consumer prices, disrupt supply chains across North America and complicate ongoing USMCA trade talks.
