Canada Shields Steel and Lumber Industries From Tariffs

Canada is rolling out a fresh layer of industrial protection as steel and lumber producers absorb the shock of steep US tariffs that have redefined cross-border trade flows. 

Ottawa will cut steel import quotas from non-free-trade partners to 20% of 2024 volumes, down from 50%, while countries with trade agreements will see limits reduced to 75% from full 2024 access. The US and Mexico remain exempt under the USMCA framework.

The new policy also introduces a 25% global tariff on selected steel-derivative products and tighter border controls aimed at curbing dumping. The steel sector alone contributes more than C$4 billion to Canadian GDP and directly employs over 23,000 workers, making it one of the hardest hit by Washington’s 50% tariff on Canadian steel. Softwood lumber faces even heavier pressure, now taxed at roughly 45% following the latest US increase.

Canada’s export exposure remains deeply concentrated, with over 75% of total exports destined for the US, and roughly 90% of lumber, aluminium, and steel shipments tied to a single market. That dependency is now being actively unwound.

What Does This Mean for Me?

Canada will offer support to target workforce retention, balance-sheet stress, and corporate restructuring for firms caught in the tariff crossfire, alongside incentives to prioritise Canadian materials in residential construction. 

The shift comes as trade talks between Ottawa and Washington remain frozen, even as US firms count the rising cost of tariff escalation.
