Canada to Seek One-Year Extension of Steel and Aluminum Tariff Measures

Ottawa moves to maintain tariff-rate quotas and U.S. relief as it pursues CUSMA renewal talks

By Leila Farooq

The Canadian government has signaled its plan to extend central steel and aluminum tariff measures for an additional year to protect domestic producers from global trade distortions. Subject to formal approval, the move would prolong tariff-rate quotas for non-CUSMA partners until June 27, 2027, and continue horizontal tariff relief for eligible U.S. steel and aluminum products until June 30, 2027. Imports above quota thresholds would remain liable for a 50% tariff, while the United States and Mexico would remain exempt from the quota limits.

Canada to Seek One-Year Extension of Steel and Aluminum Tariff Measures

Key Points

  • Tariff-rate quotas for non-CUSMA partners would be extended to June 27, 2027.
  • Horizontal tariff relief for eligible U.S. steel and aluminum products would be extended to June 30, 2027.
  • Imports exceeding quota thresholds would continue to face a 50% tariff while the United States and Mexico remain exempt from those quota limits.

Canada announced on Wednesday its intent to extend a set of steel and aluminum trade measures by one year, a policy aimed at insulating domestic manufacturers and workers from what the government described as global trade distortions and non-market practices.

Pending formal approval, the extension would keep in place the country's steel tariff-rate quotas that apply to non-CUSMA partners through June 27, 2027. At the same time, horizontal tariff relief for qualifying U.S. steel and aluminum shipments would be extended to June 30, 2027.

Under the proposed regime, imports that exceed the established quota thresholds would continue to face a 50% tariff penalty. Ottawa will maintain an exemption for its continental CUSMA partners - the United States and Mexico - from those specific quota limits.

"Supporting Canada’s steel and aluminum industry means strengthening our regional economies and the future of shared prosperity," said François-Philippe Champagne, Minister of Finance and National Revenue. He noted that the one-year extension provides the clarity businesses need while protecting jobs from global excess capacity.

The tariff actions come as Canada has formally notified the United States and Mexico that it seeks a renewal of the CUSMA free trade agreement ahead of a scheduled July 1 review. Canada-U.S. Trade Minister Dominic LeBlanc traveled to Washington on Tuesday to meet with U.S. Trade Representative Jamieson Greer, accompanied by Chief Negotiator Janice Charette.

Officials described the high-level engagement as a key resumption of direct communications after President Donald Trump abruptly scrapped bilateral trade talks in October. Mexico has also urged a prompt CUSMA renewal following two days of formal bilateral discussions with U.S. officials held last week.

The government's stated objective with the one-year measure is to give businesses the policy clarity they require while guarding jobs against the effects of global excess capacity. The proposed schedule fixes precise cutoff dates for the tariff arrangements and retains the 50% penalty for over-quota shipments, while preserving the exemption for CUSMA partners.


Summary: The Canadian government plans a one-year extension of steel tariff-rate quotas for non-CUSMA partners through June 27, 2027, and extends horizontal tariff relief for eligible U.S. steel and aluminum products to June 30, 2027. Imports above quotas would be subject to a 50% tariff, and the United States and Mexico remain exempt from the quota limits. The move accompanies formal steps toward renewing the CUSMA agreement and renewed bilateral engagement in Washington.

Key points:

  • Tariff-rate quotas for non-CUSMA partners extended to June 27, 2027.
  • Horizontal tariff relief for eligible U.S. steel and aluminum products extended to June 30, 2027.
  • Imports above quota thresholds will incur a 50% tariff; the United States and Mexico remain exempt from those quota limits.

Risks and uncertainties:

  • The extension is subject to formal approval - final adoption is not guaranteed.
  • Ongoing negotiations and the CUSMA renewal process could affect the timeline or scope of trade measures as discussions continue.
  • Resumption of direct talks does not ensure immediate resolution of underlying trade differences highlighted by prior cancellations of negotiations.

Risks

  • The proposed extension is subject to official approval and could still be altered or rejected.
  • Ongoing CUSMA renewal talks and bilateral negotiations may change the timing or details of the measures.
  • Resumption of direct communications does not eliminate the uncertainty stemming from previously aborted talks, which could affect outcomes.
