November 2025: Canada tightens steel quotas and taxes derivatives

Dated entry. This covers 30 November 2025 and has not been updated since. Tariff rules change constantly and some of this will have been superseded — check the official sources before acting on it.

On 26 November 2025 Canada announced a package of steel measures, all effective 26 December 2025.

Tariff-rate quotas for non-FTA countries were cut from 50% to 20% of 2024 volumes. Quotas for FTA countries dropped from 100% to 75%. Over-quota volumes in both cases faced a 50% surtax. Canada kept its existing CUSMA carve-out.

A new 25% tariff on roughly C$10 billion of steel derivative products from all countries was added, covering doors and windows, wires, fasteners, bridge components and wind towers.

Remission rules split: relief for steel used in manufacturing, processing, food and beverage packaging and agriculture was set to expire 31 January 2026, while relief for steel used in autos, auto parts and aerospace, and for all aluminum, continued.
