Hundreds of Canadian steelworkers are facing an uncertain future as Ottawa escalates its confrontation with one of America’s largest steel producers. Prime Minister Mark Carney’s government is threatening legal action that could force Cleveland-Cliffs to sell its Canadian assets after the company announced plans to eliminate up to 500 jobs at Stelco’s Ontario operations.
Industry Minister Mélanie Joly intensified the warning on October 16, saying the American company must honour employment commitments made when it acquired Stelco in 2024. Those promises were conditions of federal approval and are supposed to remain in effect for five years.
Cleveland-Cliffs maintains that deteriorating market conditions and American tariffs justify its decisions and disputes the government’s allegations.
With layoffs already underway in Hamilton, the disagreement has become a major test of Canada’s ability to protect industrial jobs, enforce foreign-investment agreements and preserve domestic steel production.
Ottawa Is Threatening to Force Stelco’s American Owner to Sell
The dispute reached a new level on October 16 when Industry Minister Mélanie Joly warned Cleveland-Cliffs that failing to protect Canadian employment could lead to the forced sale of its domestic assets. Speaking at the Canadian Club in Toronto, Joly accused the company of breaking commitments tied to its acquisition of Stelco. She said the federal government was prepared to use its legal powers to preserve Canadian steelmaking capacity and protect workers facing layoffs.
The warning followed an October 5 letter to Stelco president Paul Simon demanding a plan demonstrating how the company would meet its original obligations. Ottawa initially gave Cleveland-Cliffs five business days to respond. The company subsequently rejected the government’s interpretation and proceeded with layoffs. Joly said government lawyers were reviewing the dispute and suggested further action could come within days. However, no court-ordered sale had been announced. The possibility remains a legal option rather than a completed government intervention.
Cleveland-Cliffs Promised to Protect Canadian Jobs for Five Years
The controversy centres on conditions attached to Cleveland-Cliffs’ 2024 takeover of Stelco. The Ohio-based steel producer agreed to acquire the Canadian company in a transaction valued at approximately US$2.5 billion, or C$3.4 billion, including debt. Federal authorities approved the acquisition in October 2024 after reviewing whether the investment would provide a net economic benefit to Canada. The transaction was completed on November 1 of that year.
Approval came with legally binding commitments extending over five years. Cleveland-Cliffs agreed to maintain at least the same number of unionized employees as existed when the transaction was announced, retain the vast majority of non-union employees and honour existing collective agreements, benefits and pensions. The company also committed to maintaining Stelco’s Hamilton headquarters and making significant capital and research investments. Ottawa argues those promises cannot simply disappear when business conditions become difficult. Cleveland-Cliffs disputes that its planned temporary layoffs violate the agreement. The precise legal interpretation has not yet been settled by a court.
Up to 500 Jobs Are Affected Across Two Ontario Facilities
Stelco announced on September 28 that it would indefinitely idle cold-rolled and coated steel operations at Hamilton Works. Those facilities produce steel used in automobiles, appliances and construction materials, including corrosion-resistant galvanized products. The shutdown process began in October, with the company indicating that weak demand, trade disruptions and continuing pressure from foreign imports had made the affected operations increasingly difficult to sustain.
The company’s announcement identified up to 500 affected positions across Hamilton Works and Lake Erie Works in Nanticoke. United Steelworkers initially estimated approximately 350 layoffs in Hamilton and another 40 at Lake Erie, although the company’s broader potential impact figure remained higher. Production at Lake Erie Works was not being shut down completely, and Cleveland-Cliffs said it intended to concentrate more of its Canadian steelmaking activity there. The company also indicated that some Hamilton workers could pursue available positions at the Nanticoke facility. Those opportunities would not necessarily replace every position affected by the restructuring.
Workers Have Already Started Receiving Layoff Notices
For Stelco employees, the consequences have moved beyond company announcements and political statements. Workers began receiving individual layoff notices during the week of October 5, with some reportedly told not to return for their next scheduled shift. United Steelworkers Local 1005 president Ron Wells said approximately 90 employees were expected to receive notices during the initial week, with the first layoffs taking effect on October 11.
Wells indicated the reductions would unfold over roughly three weeks as equipment was gradually shut down and prepared for an extended period without production. The company describes the layoffs as indefinite, while the union has characterized them as temporary under its collective agreement. That distinction provides little immediate certainty for families managing mortgages, groceries and other regular expenses. Hamilton’s steelworkers also have a long-established connection to the community: Local 1005 traces its history to 1942 and its successful union-recognition strike in 1946. The union has been directing affected workers toward employment and retraining assistance, including an information session held on October 14.
The Investment Canada Act Could Allow a Court-Ordered Sale
The federal government’s strongest potential weapon is the Investment Canada Act, which governs significant foreign investments and includes mechanisms for enforcing commitments made by international investors. Under Section 39, the industry minister can demand that a company address an alleged breach or explain why its actions comply with the law. Section 40 provides a path to court if the company does not satisfy the statutory demand.
A superior court can order an investor to meet its commitments, impose financial penalties or require divestiture of its Canadian business or assets. That last possibility is what makes Ottawa’s warning unusually serious. However, the government cannot simply announce that Cleveland-Cliffs no longer owns Stelco and transfer the company to another buyer. Judicial enforcement requires legal proceedings and a determination that the relevant requirements have been met. Cleveland-Cliffs would have an opportunity to defend its position, and court decisions can be appealed. A forced sale is legally possible, but it is not an automatic consequence of layoffs or government dissatisfaction.
Cleveland-Cliffs Says Tariffs and Imports Have Made Operations Unsustainable
Stelco has presented a sharply different explanation for its decision. In an October 9 letter to Industry Minister Joly, company president Paul Simon argued that Canadian exports of cold-rolled and coated steel to the United States had fallen 58% compared with pre-trade-war levels. He said exports of those products declined by approximately 226,000 tonnes in the second quarter of 2026 compared with the quarterly average recorded in 2024.
Simon also pointed to foreign imports accounting for approximately 45% of the Canadian market for those products. According to the company, declining exports, weaker domestic demand and continued competition have reduced the potential market for Hamilton-produced steel by more than one million tonnes annually. Cleveland-Cliffs maintains that operating the affected finishing facilities under those circumstances would generate unsustainable losses. Its position is that the five-year employment commitments do not prohibit temporary layoffs at every point during the agreement. The company has indicated it is prepared to defend that interpretation in court rather than abandon its restructuring plans.
Trump’s 50% Steel Tariffs Have Created a Complicated Conflict
The dispute is unfolding against a major deterioration in cross-border steel trade. President Donald Trump’s administration raised tariffs on imported steel to 50% in June 2025, sharply increasing the cost of Canadian products entering the American market. Canadian Steel Producers Association figures cited by Reuters indicate shipments to the United States fell approximately 60% during 2025. The decline forced manufacturers to reconsider their customers, production schedules and reliance on exports.
What makes Cleveland-Cliffs’ position particularly controversial is its chief executive’s support for those American tariffs. Lourenco Goncalves has publicly defended the measures as necessary to protect U.S. steelmaking. Canadian union leaders argue it is contradictory for a company to support tariffs that damage its Canadian operations and then cite those tariffs as justification for job reductions. Joly has echoed that criticism. However, the broader economic pressure is real, and Cleveland-Cliffs argues the company cannot continue losing money indefinitely. That leaves Ottawa confronting two overlapping questions: whether the employment commitments have been breached and whether the underlying operations remain commercially viable.
Stelco’s Troubled Ownership History Is Raising Familiar Fears
Hamilton has experienced a remarkably similar confrontation before. Stelco was founded in 1910 and became a major part of Canada’s industrial economy. In 2007, Pittsburgh-based U.S. Steel acquired the company, but the relationship deteriorated after the global financial crisis. Ottawa launched legal proceedings in 2009, alleging that U.S. Steel had failed to honour employment and production commitments attached to its takeover.
That dispute eventually ended in an out-of-court settlement in December 2011. U.S. Steel accepted additional obligations, including maintaining Canadian production, operating both major Ontario facilities until 2015 and investing at least $50 million beyond its original capital commitment. The company’s Canadian business later entered creditor protection in 2014 before emerging under Bedrock Industries in 2017. Cleveland-Cliffs’ takeover in 2024 began another chapter of American ownership. For workers who experienced earlier shutdowns, restructuring and pension uncertainty, the current confrontation has a particularly familiar character. The earlier lawsuit demonstrates that Ottawa can enforce foreign-investment undertakings, although it also shows that litigation may end in negotiated commitments rather than an immediate reversal of job losses.
Opposition Parties Are Demanding Different Forms of Intervention
The threat to Stelco has generated pressure across Canada’s political spectrum, although parties disagree over the best response. Conservative Leader Pierre Poilievre has urged Ottawa to sue Cleveland-Cliffs over its employment commitments. He has also called for stronger measures against unfair steel imports, greater domestic industrial competitiveness and renewed negotiations to remove American tariffs. His criticism focuses heavily on the government’s handling of the wider Canada-U.S. trade relationship.
New Democratic Party Leader Avi Lewis and Ontario NDP Leader Marit Stiles have called for public ownership of Stelco, arguing that nationalization would provide a more direct way to protect production and employment. Joly has separately discussed the possibility of federal equity investments in strategically important industries, including support through government financing. She has not announced a specific plan to purchase Stelco. These distinctions matter. Forcing Cleveland-Cliffs to sell to another private buyer, having Ottawa acquire a stake and nationalizing the entire company are different approaches with different financial consequences. None guarantees that demand for Canadian steel will immediately recover.
Ottawa’s Next Decision Could Shape Canada’s Steel Industry
The immediate question is whether Ottawa will turn its legal warning into formal proceedings or secure a negotiated agreement with Cleveland-Cliffs. On October 16, Joly said the government had retained lawyers and was reviewing available enforcement measures. Cleveland-Cliffs, meanwhile, has maintained its intention to reduce operations while leaving open the possibility of restoring jobs if market conditions improve. The company’s next quarterly financial results, scheduled for October 19, may provide additional insight into the economic pressures affecting its Canadian business.
The conflict also arrives as Canada’s wider steel industry searches for new customers. Reuters reported that domestic demand from mining, energy, construction and data-centre projects is helping some producers offset lost American sales. Ottawa has offered C$1 billion in loans across the steel, aluminum and copper industries and strengthened import restrictions to support domestic producers. Nevertheless, Stelco’s future depends on more than government assistance. The outcome will test whether Canada can enforce promises made by foreign investors while keeping strategically important manufacturing economically sustainable. For hundreds of Ontario workers, that outcome could determine whether a temporary interruption becomes a lasting loss of employment.
