The recent doubling of U.S. tariffs on steel imports-from 25% to 50% since June 2025-has raised alarms in Canada's steel industry about potential exclusion from the U.S. market. The tariffs were imposed amid ongoing trade tensions, targeting steel and aluminum from various countries including Canada. In response, Canada has introduced its own tariff-rate quotas and 50% surtaxes on steel imports beyond set limits from non-free trade partners to protect domestic producers. While some Canadian steel companies are concerned about lost market access, others express confidence that they will adjust by seeking new markets and increasing efficiency. The Canadian government also plans to bolster the use of Canadian steel in domestic projects, including housing and defense, to offset challenges. Despite the uncertainty, industry leaders emphasize collaboration with the government to navigate the evolving trade landscape and safeguard jobs and production in Canada's steel sector. Steel industry leaders warn that steel dumping-selling ultra-low-priced steel into Canada-is worsening market conditions despite tariffs. Algoma Steel CEO Michael Garcia says existing tariffs harm revenue, and doubling them threatens U.S. business viability. Zekelman Industries' CEO accuses China of rerouting cheap steel through Asian countries to avoid tariffs.
