Stelco to idle Hamilton plant and lay off up to 500 workers

Stelco Holdings Inc. has announced it will indefinitely idle its cold-rolled and coated steel operations at its Hamilton Works plant in Ontario, effective October 9. The company, a subsidiary of the U.S.-based Cleveland-Cliffs Inc., cited a shrinking market and weak demand as primary drivers for the decision. Stelco expects the move to affect up to 500 workers, though United Steelworkers Local 1005 president Ron Wells estimates the immediate layoffs will be around 350.

The company plans to concentrate its production at the Lake Erie Works facility in Nanticoke, Ontario, stating that overall steel tonnage will remain unchanged. Cleveland-Cliffs indicated that a significant number of the displaced Hamilton workers could be absorbed by the Nanticoke plant.

Canadian Prime Minister Mark Carney has condemned the move, accusing Cleveland-Cliffs of “betraying” Canadian workers. Carney noted that the company has binding employment obligations stemming from its C$3.4 billion acquisition of Stelco in 2024. He threatened legal action to ensure these obligations are met. The layoffs are being viewed by industry experts as a direct consequence of the escalating trade war, specifically the 50% U.S. tariffs on Canadian steel and aluminum, which have severely impacted the manufacturing supply chain.
