• Canada applies its steel measures in a fixed order and charges only one of them on a good: "Canada maintains a non-stackable policy for the following tariffs on steel and aluminum." The order is: first the over-quota (TRQ) surtax, then the US or China surtaxes, then the steel derivative surtax. Source: canada.ca (as of 2026-09-24)
• Tariff-rate quota (TRQ) means a set volume of imports that can enter without the surtax. Above that volume the surtax applies. "In both cases, imports exceeding the tariff rate quota volumes are subject to a 50% surtax." Source: canada.ca (as of 2026-09-24)
• Since December 26, 2025, quotas have been set at "20% of 2024 import levels for countries that do not have a free trade agreement in force with Canada" and "75% of 2024 import levels for countries that have a free trade agreement in force with Canada." Source: canada.ca (as of 2026-09-24)
• The over-quota surtax does not apply to Canadian, US or Mexican steel: "Imports of subject steel products originating in Canada, the United States, and Mexico are exempted from this measure." The goods covered are listed by tariff classification number in Schedules 1 and 2 of the Order Imposing a Surtax on the Importation of Certain Steel Goods (SOR/2025-148).

Several steel surtaxes now overlap, and since 2025 they have changed on fixed dates. A 25% surtax on US steel started March 13, 2025, and went to 50% for steel goods in a new Schedule 2.1 on September 8, 2026 (cbsa-asfc.gc.ca). An over-quota surtax of 50% on non-CUSMA steel started June 27, 2025, its quotas were cut on December 26, 2025, and it was extended to June 27, 2027 (cbsa-asfc.gc.ca). A 25% surtax on 61 steel derivative tariff items from all countries started December 26, 2025 (canada.ca, canada.ca). Only one measure applies per good, in a set order of precedence, so the rate on a shipment depends on its origin, its tariff item and how much of the quota is left (canada.ca).
