Canada to extend steel and aluminum tariff measures to support workers and businesses

On June 3, 2026, The Canada Border Services Agency (CBSA) has issued a new trade advisory announcing that the government of Canada will be extending key steel and aluminum tariff measures for one year.

Subject to approval by the Governor in Council, Canada will extend its steel tariff-rate quotas (TRQ) regime for imports from non-CUSMA partners, and the existing horizontal tariff relief for eligible steel and aluminum products from the United States (U.S.), and additionally, for eligible steel products subject to derivative tariffs. These measures would be extended to June 27 and June 30, 2027, respectively.

This proposed one-year extension is part of Canada’s commitment to defend steel workers and industry against steel trade diversion and non-market policies and practices that drive global excess capacity. It will provide producers and importers with greater business predictability and longer-term certainty.

Following the planned extension of steel TRQs, the government intends to initiate efforts towards the inclusion of an allocations-based approach for the administration of quota for certain product classes. Stakeholders, including producers and importers, will be offered the opportunity to share their views on the approach, reflecting the government’s ongoing commitment to review and improve the TRQ framework.

Current quota levels for the TRQs would continue to be based on 20% of 2024 volumes for partners without a free trade agreement with Canada, and 75% for partners with a free trade agreement in force with Canada. Imports exceeding quota limits will continue to be subject to a 50% tariff. Canada will also continue to exempt its CUSMA partners, the United States and Mexico, from the TRQs.
