Stelco Holdings Inc. is preparing to indefinitely idle some of its operations at its Hamilton Works facility, putting up to 500 jobs at risk as the Canadian steel industry continues to face pressure from U.S. tariffs, imports and weaker market demand. The company said Monday that it will wind down its cold-rolled and coated steel operations at the Hamilton facility beginning around October 9. The decision is part of a plan to concentrate more of its steel production at the company’s Lake Erie Works facility in Nanticoke, Ontario. Stelco said the decision was difficult but necessary because of prolonged market uncertainty and challenging conditions affecting its cold-rolled and galvanized steel businesses. The company said demand for these products in the markets traditionally served by Stelco fell by almost 25 per cent in the second quarter of 2026, compared with the quarterly average in 2024. Demand in Canada alone declined by about 10 per cent during the same comparison period. Stelco has pointed to the broader trade dispute between Canada and the United States as one of the major factors affecting its business. U.S. tariffs on Canadian steel have made conditions more difficult for Canadian producers, while imports into Canada have also remained a concern for the company. The United Steelworkers union, which represents workers at the Hamilton facility, said the company indicated that hundreds of production positions could be affected. Union president Ron Wells estimated that about 350 workers could ultimately lose their jobs, although the company has indicated that the number could be closer to 500. The exact number of layoffs will depend on how the shutdown and workforce transition are implemented. Stelco said the move will not eliminate its overall ability to produce steel. Instead, the company plans to change its product mix and concentrate production at its Lake Erie Works facility. The company expects a significant number of employees affected by the Hamilton shutdown to be offered employment opportunities at the Nanticoke operation. Workers who are offered positions there would, however, face a change in workplace location.
For Hamilton workers and their families, the announcement has created uncertainty about employment, commuting and the future of steel production in the city. The Hamilton facility has been an important part of the city’s industrial history for generations, and the steel sector remains closely connected to the local economy through direct employment, suppliers, contractors and other businesses. The latest layoffs are also part of a broader period of uncertainty for Canada’s steel industry.
Other Canadian steel producers have announced significant job reductions and operational changes over the past year as they deal with tariffs, weaker demand and changing market conditions. Stelco’s parent company, Cleveland-Cliffs Inc., acquired the Canadian steelmaker in 2024. Cleveland-Cliffs has said the company will continue producing steel in Canada, with the Nanticoke facility becoming more central to its operations. The company said it will continue monitoring market conditions and will evaluate the status of the Hamilton operations if conditions improve. The federal government has introduced measures aimed at protecting Canada’s steel industry, including tariffs and import controls. However, steel producers and unions have continued to argue that stronger measures may be needed to protect domestic production and jobs. The situation is particularly sensitive because Canadian steel producers operate within an integrated North American market. Steel produced in Canada is used by manufacturers in construction, automotive production, appliances, infrastructure and other industries.
Changes in tariffs can therefore affect not only steelmakers but also companies that purchase, process and manufacture products using Canadian steel. The trade dispute has also created uncertainty for Canadian manufacturers that rely on exports to the United States. Higher tariffs can make Canadian products more expensive in the American market and can affect demand for particular types of steel. For Stelco, the immediate focus will be on winding down the affected Hamilton finishing operations and determining which employees can transition to Lake Erie Works. The company says it is working with union representatives to meet its obligations under existing collective agreements as the changes are implemented. The future of the Hamilton operations could ultimately depend on changes in market conditions, trade policies and demand for cold-rolled and coated steel.
For now, the company has described the idling as indefinite, rather than a permanent closure, leaving open the possibility that operations could be reassessed if market conditions improve. The announcement nevertheless represents a significant blow to Hamilton’s steel workforce, with hundreds of employees facing layoffs or potential relocation at a time when Canada’s steel industry is already dealing with substantial trade and market pressures.
