Stelco's U.S. owner has defended the decision to idle operations at its Hamilton steel plant, despite recent layoffs and legal threats from the Canadian Prime Minister. The CEO of Stelco stated that no amount of money would have prevented the slowdown and job losses, further escalating tensions between the U.S. and Canada over trade and industrial policy. The Canadian Prime Minister has vowed legal action against the shutdown, while Stelco's owner maintains the decision was necessary. The dispute highlights ongoing trade and industrial policy conflicts between the two nations.
