According to Steel World Review, steelmaker Stelco plans to halt operations at its cold-rolling and coating lines at its Hamilton, Ontario, plant from October 9. Citing Reuters, the decision could affect up to 500 workers. Stelco, which is owned by U.S.-based Cleveland-Cliffs, said it will concentrate its production at its Nanticoke facility and will consider job opportunities for Hamilton employees at that unit.
he company identified U.S. tariffs and market pressures as factors contributing to the decision. Tariffs imposed by the Trump administration on imports of certain steel and aluminum products from Canada, according to Reuters, reach as high as 50%. However, the company has not yet characterized the shutdown of the lines as a definitive reduction in overall Canadian steel production and has instead announced a shift in its production focus to Nanticoke.
In response to the potential layoffs, the Canadian government has given Cleveland-Cliffs five business days to submit a plan to preserve jobs. Mélanie Joly, Canada’s Minister of Industry, says that when the government approved the acquisition of Stelco in 2024, maintaining the number of unionized employees and the majority of non-unionized positions was a condition of the transaction.According to her, changing market conditions or business strategy does not automatically cancel these commitments, and Ottawa will consider legal action if necessary.
The dispute has brought the consequences of trade tariffs beyond cross-border trade and into production and employment decisions at a steel plant. At the same time, the Canadian government’s position represents a test of the enforcement of employment commitments associated with the acquisition of an industrial company by a foreign owner. The shutdown of the Hamilton lines could alter the location and composition of rolled-product production, although the final number of job losses and the impact of this shift on Canadian production remain unclear.
What remains unclear: Cleveland-Cliffs’ final response to the government’s deadline, the exact number of employees affected, and Ottawa’s decision regarding legal action have not been announced. The attribution of tariffs as a cause is the company’s explanation for the production decision and should be reported as such.
