Canadian Steelmakers Turn to Domestic Demand After U.S. Tariffs
Canada's steel sector is redirecting more production toward its domestic market after U.S. tariffs sharply reduced cross-border shipments, with mining, energy and AI infrastructure projects, tighter import controls and federal procurement policies providing support. The recovery, however, remains uneven across producers and regions.
- U.S. tariffs: Section 232 steel tariffs were increased from 25% to 50% effective June 4, 2025.
- Export impact: Canadian steel shipments to the U.S. fell about 60% in 2025, according to the Canadian Steel Producers Association.
- Domestic share: United Steelworkers calculates that Canadian-made steel's share of Canadian consumption rose from 41% in 2024 to 51% in 2025.
- Demand outlook: OECD estimates Canadian steel demand grew about 2.7% in 2025 and projects another 0.9% increase in 2026.
- Government measures: Canada is using steel import quotas, financing programs and Buy Canadian procurement requirements to support domestic producers.
- Regional split: Western Canadian projects are providing new opportunities while Stelco's Hamilton operations face production cuts and hundreds of potential layoffs.
Canada's steel adjustment is best understood as a shift in market destination rather than a full recovery from the U.S. tariff shock. Domestic producers are capturing a larger share of Canadian demand while federal policy is limiting some foreign competition and directing public procurement toward Canadian steel. New infrastructure projects provide additional demand potential, but the 60% collapse in U.S.-bound shipments and continuing layoffs show that domestic substitution has not replaced the scale or economics of the former U.S. export market.
TORONTO, Oct. 16 (Reuters): Canada's steel industry is showing early signs of adapting to sharply reduced U.S. market access as producers compete more aggressively for domestic orders and major Canadian infrastructure projects generate new demand.
The shift follows the U.S. decision to increase Section 232 tariffs on imported steel and aluminum from 25% to 50%, effective June 4, 2025.
Canada had historically sent more than 90% of its steel exports to the United States, making the industry particularly exposed to the tariff increase.
According to the Canadian Steel Producers Association (CSPA), shipments to the U.S. subsequently fell by approximately 60% in 2025.
Canadian Steel Producers Shift Toward the Home Market
The loss of U.S. export access has pushed Canadian producers to compete more aggressively for domestic customers.
United Steelworkers (USW) estimates that Canadian-produced steel accounted for 51% of steel consumed in Canada in 2025, up from 41% in 2024.
Over the same period, the calculated share supplied by imports fell from 59% to 49%.
USW economic researcher Guio Jacinto told Reuters that the union derived the figures from world steel data and Canadian import statistics.
David Fritz of Alberta-based fabricated-steel producer Supreme Steel told Reuters that more Canadian companies are now competing for domestic business, leaving less room for overseas suppliers.
“I feel optimistic for the outlook of fabricated steel market in Canada.”
Fritz said the number of projects in the development pipeline is sufficient to support the fabricated-steel sector.
Canadian Steel Demand Is Forecast to Grow 0.9% in 2026
The domestic demand environment is providing some support for the shift.
The OECD estimates that Canadian steel demand increased approximately 2.7% in 2025 and projects further growth of around 0.9% in 2026.
| Canada Steel Demand | Change | Status |
|---|---|---|
| 2025 | +2.7% | OECD estimate |
| 2026 | +0.9% | OECD projection |
Western Canada Projects Provide New Steel Demand
Reuters identified mining, energy and AI infrastructure as important areas of emerging Canadian steel demand, particularly in Western Canada.
One of the largest projects is Bell Canada's planned AI data-centre expansion in Saskatchewan.
In September, Bell announced plans to increase the project's capacity to 1.2 gigawatts.
The federal and Saskatchewan governments said the development could represent more than C$50 billion in capital investment.
Large data-centre projects can create demand for structural steel, electrical infrastructure, transmission equipment and related construction materials, although the amount of Canadian steel ultimately used will depend on project procurement and design specifications.
Pacific Link Pipeline Could Add Major Canadian Steel Demand
The energy sector is another potential source of domestic steel demand.
On October 1, Prime Minister Mark Carney formally listed Canada's proposed Pacific Link oil pipeline as a project of national interest under the Building Canada Act.
The planned pipeline is intended to increase Canada's oil-export capacity to Asian markets by approximately one million barrels per day, reducing dependence on the United States.
The federal government has explicitly said it intends to give preference to Canadian-made materials and Canadian steel for the project.
Canada Uses Steel Import Quotas to Support Domestic Producers
The industry's domestic pivot is also being reinforced by federal trade measures.
Canada introduced tariff-rate quotas on steel mill products in 2025 to reduce the risk that material displaced by U.S. tariffs and global excess capacity would be redirected into the Canadian market.
The current TRQ structure applies to covered imports from non-CUSMA countries.
| Supplier Category | Current Quota Basis | Above-Quota Tariff |
|---|---|---|
| Non-FTA partners | 20% of 2024 volumes | 50% |
| Non-CUSMA FTA partners | 75% of 2024 volumes | 50% |
Canada announced in June that the TRQ system would be extended for another year, with the current regime intended to continue to June 27, 2027, subject to the applicable government approvals and administration.
Buy Canadian Rules Direct Federal Demand Toward Domestic Steel
Federal procurement policy is another part of Canada's strategy.
The government's Buy Canadian framework took effect in December 2025 and requires Canadian-produced steel, aluminum and wood in qualifying large federal defence and construction projects where Canadian supply is available.
For the Canadian-material requirement, the policy applies to federal defence and construction contracts worth at least C$25 million where the relevant materials requirement is at least C$250,000.
Separately, the threshold for strategic federal procurements receiving Canadian supplier and content preferences was lowered from C$25 million to C$5 million effective June 15, 2026.
Ottawa Provides C$1 Billion Financing Program
The federal government has also introduced direct financing support for industries affected by U.S. tariffs.
In May 2026, Ottawa announced a C$1 billion Business Development Bank of Canada financing program for manufacturers and exporters affected by tariffs and working with products containing steel, aluminum or copper.
The program was designed to provide working capital and other financing as companies adjust to disrupted trade conditions.
Canada's broader steel support also includes the Strategic Response Fund, regional tariff-response programs and procurement measures.
Recovery Remains Uneven as Stelco Cuts Hamilton Operations
The stronger domestic outlook has not prevented substantial disruption in Ontario.
Cleveland-Cliffs' Stelco subsidiary moved to indefinitely idle its cold-rolled and coated steel operations at Hamilton Works beginning in October.
The changes could affect up to 500 employees.
Stelco has said it will concentrate steel production at its Nanticoke operation and has attributed the restructuring to unsustainable market conditions linked to trade disruption and continued import pressure.
The federal government has challenged the job reductions because Cleveland-Cliffs made employment-related undertakings when its Stelco acquisition was approved under the Investment Canada Act.
Ottawa has threatened legal action if it concludes the company has breached those commitments. Cleveland-Cliffs and Stelco dispute that the planned changes violate the undertakings.

Has Canada's Steel Industry Recovered From U.S. Tariffs?
The evidence supports a partial adjustment rather than a complete recovery.
Canada is using more domestically produced steel, overall steel demand is still growing modestly, and major energy, mining and digital-infrastructure projects are creating new opportunities for producers and fabricators.
Federal import restrictions and procurement policies are also improving the competitive position of Canadian mills in their home market.
However, U.S.-bound steel shipments remain dramatically below pre-tariff levels, hundreds of workers have been affected by production reductions, and the Canadian market alone has not replaced the scale of the industry's former U.S. customer base.
