Stelco plans to idle Hamilton finishing operations as tariffs shrink demand

Stelco announced on September 28 that it intends to indefinitely idle cold-rolled and coated operations at Hamilton Works, with the wind-down expected to begin on or around October 9. CHCH reported that the decision could affect as many as 500 employees. The company tied the move to prolonged market uncertainty and damage to the market for its finished steel products. [1]

In a letter to employees described by CHCH, Stelco said U.S. Section 232 tariffs had sharply reduced demand for its cold-rolled and galvanized products. Demand in the markets it traditionally served was nearly 25% below the 2024 quarterly average in the second quarter of this year, including a 10% decline in Canada. Those figures are the company's account of its market conditions. [1]

Reuters separately reported the decision, citing CBC's account of an internal memo and Stelco's public statement. The company said steel production would be concentrated at its Nanticoke, Ontario facility and Hamilton employees would be offered jobs there. U.S. duties of up to 50% on Canadian steel form the trade-policy backdrop. The number of affected positions therefore should not automatically be treated as the final number of permanent job losses.

For the Canadian steel supply chain, this is a concrete change in where processing work takes place, with a stated timetable and employment consequences. The finishing-operation shutdown is distinct from a general prediction that tariffs might eventually reduce output. Transfer opportunities could change the final workforce outcome, but the announced Hamilton wind-down already provides a material planning signal for workers, suppliers and customers exposed to the affected operations.
