Hundreds of Canadian steelworkers are facing an uncertain future as a dispute over layoffs at Stelco escalates into a political and legal confrontation between Ottawa and one of America’s largest steel producers.

On October 9, 2026, Conservative Leader Pierre Poilievre demanded that Prime Minister Mark Carney’s government take immediate legal action against Cleveland-Cliffs, the U.S. company that acquired Stelco in 2024.

The dispute centres on plans to lay off up to 500 workers at the company’s Ontario facilities, despite employment commitments made during the takeover.

Industry Minister Mélanie Joly has already threatened enforcement action, while Cleveland-Cliffs argues that American tariffs and insufficient Canadian demand have made the affected operations commercially unsustainable.

With layoff notices underway and a government deadline approaching, the confrontation could determine not only the fate of hundreds of jobs but also how firmly Canada enforces promises made by foreign investors.

Poilievre Demands Immediate Legal Action Against Cleveland-Cliffs

Conservative Leader Pierre Poilievre delivered his challenge to the federal government on October 9 from LaSalle Park Marina in Burlington, Ontario. Standing across Hamilton Harbour from Stelco’s industrial operations, he announced a five-point plan intended to protect Canadian steelworkers and rebuild domestic manufacturing. His most immediate demand was that Ottawa sue Cleveland-Cliffs, the Ohio-based company that purchased Stelco in 2024. Poilievre argued that the company should be held accountable for employment commitments made when federal regulators approved the acquisition.

The Conservative leader wants legal proceedings aimed at restoring jobs and restarting production at the affected facilities. He also suggested that the courts could force Cleveland-Cliffs to sell Stelco to a Canadian owner willing to maintain operations. Poilievre urged the government to begin legal action as early as Monday, October 12, rather than continue exchanging warnings with company executives. His position adds political pressure to an already escalating dispute, although any court-ordered remedy would ultimately depend on the evidence and Canada’s investment laws.

The 500-Job Warning Is Already Becoming a Reality

The potential layoffs are no longer merely a distant possibility. Stelco began issuing individual notices to employees at its Hamilton operations during the week of October 5, following an announcement that as many as 500 workers could be affected across its Hamilton and Lake Erie facilities. United Steelworkers Local 1005 president Ron Wells said approximately 90 Hamilton workers were expected to receive notices during the first week. Initial layoffs were scheduled to take effect on Sunday, October 11, with approximately 330 Hamilton employees potentially affected over the subsequent three weeks.

Additional reductions are expected at Lake Erie Works in Nanticoke, Ontario, where union representatives have warned that between 40 and 50 workers could face layoffs as early as October 24. Other positions, including co-op placements, could also be affected. The 500 figure represents the upper end of the company’s announced reductions, not a confirmed count of employees already dismissed. Stelco plans to idle cold-rolled and galvanized steel operations in Hamilton, while reducing activity on steel pickling lines at Lake Erie Works. For affected employees, those operational decisions carry immediate consequences for household income and employment security.

Cleveland-Cliffs Made Five-Year Employment Promises When It Bought Stelco

The federal government’s legal concerns originate in the conditions attached to Cleveland-Cliffs’ acquisition of Stelco. The American company announced the transaction in July 2024, valuing Stelco at approximately US$2.5 billion, or C$3.4 billion, including debt. Ottawa approved the purchase in October 2024 following a review under the Investment Canada Act. That approval was conditional on a series of legally binding commitments intended to ensure that the foreign takeover would benefit Canadian workers and the economy.

Among those commitments was a requirement to maintain at least the same number of unionized employees and the vast majority of non-unionized workers employed when the acquisition was announced. These undertakings were set to remain in place for five years. Cleveland-Cliffs also agreed to preserve Stelco’s Hamilton headquarters, honour existing collective agreements and pension commitments, and undertake capital and research investments. The conditions were not simply promotional assurances made during a corporate announcement. They formed part of the federal government’s approval of the acquisition. Whether the proposed layoffs constitute a legal breach is now the central question confronting Ottawa, the company, and potentially the courts.

Industry Minister Mélanie Joly Has Already Issued an Ultimatum

Poilievre’s demand follows several days of increasingly forceful action by the federal government. On October 5, Industry Minister Mélanie Joly sent a letter to Stelco president Paul Simon expressing serious concern about the planned job reductions. She demanded that Cleveland-Cliffs explain how it would honour all the undertakings made during the acquisition, particularly its employment obligations. The company was given five business days to provide a compliance plan, placing the deadline on Tuesday, October 13, because Monday is Thanksgiving.

Joly has publicly rejected the suggestion that changing market conditions automatically release Cleveland-Cliffs from its obligations. She has also emphasized that the company’s chief executive previously supported the American tariffs now being cited as a cause of the restructuring. According to the minister, Ottawa is prepared to use its legal enforcement powers if the company fails to comply. Cleveland-Cliffs chief executive Lourenco Goncalves has said the company intends to respond by the Tuesday deadline, including through a confidential submission containing commercially sensitive information. As of Poilievre’s October 9 announcement, the government’s public position remained a threat of legal action rather than confirmation that proceedings had begun.

Canadian Law Could Allow Ottawa to Seek a Forced Sale

The Investment Canada Act provides the federal government with significant enforcement powers when foreign investors fail to honour binding commitments. Under Section 39, the responsible minister can issue a formal demand requiring an investor to remedy an alleged default, explain why no violation has occurred, or justify non-compliance. If the company does not satisfy the demand, Section 40 allows the government to seek a court order. Potential remedies include requiring compliance with previous undertakings, imposing financial penalties, or ordering divestiture of the Canadian business.

Those powers help explain why Poilievre believes Ottawa can pursue more than a written apology or another corporate assurance. However, forcing Cleveland-Cliffs to sell Stelco would not be automatic. A court would need to determine whether the statutory requirements were satisfied and whether the requested remedy was appropriate. The government could also pursue negotiated commitments designed to preserve employment. Even if a sale were ordered, identifying a financially capable buyer willing to operate the mills would present a separate challenge. The law gives Ottawa meaningful leverage, but it does not guarantee that every affected worker will immediately return to the job.

Stelco Has Been at the Centre of a Similar Court Battle Before

The present dispute carries uncomfortable historical echoes for Hamilton steelworkers. In 2007, U.S. Steel acquired Stelco and made commitments involving employment, production, and investment. Following the global financial crisis, the American company reduced Canadian operations and announced substantial layoffs. Ottawa subsequently concluded that U.S. Steel had failed to satisfy its commitments. In May 2009, then-industry minister Tony Clement issued a formal demand under the Investment Canada Act, and the government initiated court proceedings that July.

The legal dispute continued until December 2011, when Ottawa announced an out-of-court settlement based on new and enhanced commitments. U.S. Steel agreed to continue producing steel in Canada, operate its Hamilton and Lake Erie facilities through 2015, and make at least $50 million in additional capital investments beyond earlier obligations. The company also committed $3 million toward community and educational programs. However, the broader business continued experiencing financial difficulties, and Stelco entered creditor protection in 2014. The history demonstrates that Ottawa has previously pursued legal remedies against a foreign steel owner. It also illustrates that even successful enforcement cannot eliminate every economic challenge confronting an industrial employer.

Cleveland-Cliffs Says Canadian Demand Cannot Support Its Operations

Cleveland-Cliffs presents a different explanation for the restructuring. Chief executive Lourenco Goncalves argues that Canada’s domestic market does not generate enough demand to support the existing supply of galvanized steel. He has pointed to competition from imports and other Canadian producers, including ArcelorMittal Dofasco. According to Goncalves, some operations have been running at approximately 50% to 55% of capacity, making profitable production difficult. The company maintains that idling certain operations is a commercial decision rather than an attempt to abandon Canada.

In comments reported October 9, Goncalves described the layoffs as temporary and said affected employees would be recalled if Canada and the United States reached a steel trade agreement restoring viable market access. He also argued that the reductions were intended to preserve more than 2,000 other jobs. However, the executive’s support for American steel tariffs has intensified criticism from Canadian politicians and unions. Goncalves has defended Section 232 tariffs as successful American trade policy while advocating stronger Canadian protections against foreign steel. His position highlights the central contradiction facing the company: tariffs he supports may benefit its American operations while undermining its Canadian production network.

Trump’s Steel Tariffs Have Deepened Canada’s Manufacturing Crisis

The current dispute cannot be separated from the Trump administration’s steel policies. Washington imposed a 25% tariff on steel imports in 2025 and increased the rate to 50% on June 4 of that year. The restrictions were introduced under Section 232 of American trade law, which allows import measures justified on national security grounds. Subsequent changes to the U.S. metals tariff regime have maintained substantial duties on many steel products, including Canadian exports. These restrictions have weakened access to a market that has historically absorbed most Canadian steel shipments.

The Bank of Canada’s April 2026 economic analysis estimated that Canadian steel exports had fallen by approximately half following the introduction of American trade restrictions. For a producer operating large industrial facilities, that kind of decline creates immediate pressure on production volumes, equipment utilization, and employment. Steel mills require substantial fixed investment, and their operating costs do not fall proportionately when orders disappear. Canadian steel also competes with products from countries facing different trade barriers and production costs. Although tariffs are not the only explanation for Stelco’s difficulties, they have significantly altered the commercial environment in which its new owner must operate.

Steelworkers Say Their Jobs Have Become Political Bargaining Chips

The United Steelworkers has been among the most outspoken critics of the proposed layoffs. In an October 1 statement, Locals 1005 and 8782 condemned Cleveland-Cliffs’ decision and argued that the company was failing to honour its acquisition commitments. The unions also questioned the company’s reliance on trade disruptions as justification, pointing to its chief executive’s public support for Trump’s tariffs. Both locals urged Prime Minister Carney and Industry Minister Joly to enforce the obligations attached to the foreign takeover.

For workers in Hamilton and Nanticoke, the controversy is about more than negotiations between governments and corporate executives. Ron Wells, who has worked at the Hamilton steel mill for 47 years, has expressed concern that employees are being caught between competing political and commercial interests. At Lake Erie Works, Local 8782 president John McElroy has warned that many affected employees are primary household earners and that comparable well-paying jobs can be difficult to find locally. His union has been exploring reassignment opportunities for workers who might otherwise be laid off. These efforts may provide relief for some employees, but uncertainty remains over how many positions can be preserved and for how long.

Poilievre’s Five-Point Plan Extends Beyond the Stelco Lawsuit

The proposed lawsuit is only the first component of Poilievre’s broader steel strategy. His plan also calls for stronger measures against unfairly traded Chinese steel, eliminating Canada’s industrial carbon pricing system, accelerating liquefied natural gas projects, and negotiating an agreement with Washington that removes American steel tariffs. Poilievre argues that these measures would protect existing steel production while creating additional demand for Canadian materials. He also appointed Conservative MP Michael Guglielmin, who has more than two decades of steel industry experience, to chair a new Conservative steel caucus.

Each proposal addresses a different part of the industry’s difficulties. Anti-dumping enforcement targets steel sold under unfair trade conditions, while faster LNG development could generate demand for construction materials and industrial equipment. Removing industrial carbon pricing could reduce certain costs for producers, although it would also change Canada’s approach to industrial emissions. The proposal concerns industrial carbon pricing, not the federal consumer fuel charge, which was eliminated in April 2025. A negotiated tariff agreement could provide more direct relief to Canadian steel exporters, but its timing and terms would depend on Washington. The measures therefore represent proposed policy responses rather than established solutions to Stelco’s immediate employment crisis.

Ottawa Has Already Introduced Measures to Protect Canadian Steel

The Carney government has not relied exclusively on threats against Cleveland-Cliffs. Ottawa has introduced tariffs, import quotas, procurement requirements, and financing programs intended to protect domestic steel production. Under measures that took effect in December 2025, covered steel imports from countries without a Canadian free trade agreement face stricter tariff-rate quotas based on 20% of their 2024 import volumes. Covered products from other non-CUSMA free trade partners face quotas based on 75% of earlier volumes. Imports exceeding those limits generally face a 50% surtax.

The federal Buy Canadian framework also requires domestically produced steel, aluminum, and wood products in qualifying federal construction and defence contracts valued at $25 million or more, provided the materials involved meet the $250,000 threshold and Canadian supply is available. Ottawa has also provided access to major financing initiatives, including a $5-billion Strategic Response Fund and a $1-billion Business Development Bank of Canada program for metal manufacturers and exporters. These policies could support Canadian producers over time. However, they do not automatically create enough orders for every existing mill. Cleveland-Cliffs argues that protections remain insufficient for galvanized steel, while the federal government maintains that companies must still honour their legally binding employment commitments.

The Next Deadline Comes as Canada’s Labour Market Weakens

The Stelco dispute is unfolding against a difficult national employment backdrop. Statistics Canada reported on October 9 that employment declined by approximately 68,000 positions in September, following a loss of 42,000 in August. Manufacturing employment fell by about 13,000 during September, while the national unemployment rate increased to 6.5%. These figures do not establish that every lost job resulted from American tariffs, but they show why another round of manufacturing layoffs has attracted political attention.

The immediate deadline is October 13, when Cleveland-Cliffs is expected to provide Ottawa with its plan for honouring the 2024 acquisition commitments. Poilievre wants court action sooner, while the Carney government has indicated that enforcement proceedings could follow if the response is unsatisfactory. Beyond that deadline, the industry’s outlook will depend partly on broader Canada-U.S. negotiations. Washington declined to renew the existing USMCA arrangement during its July 2026 joint review, although the agreement remains in force while discussions continue. For Stelco workers, the decisive measure will not be which politician delivers the strongest warning. It will be whether legal enforcement, renewed steel orders, or a negotiated trade agreement can keep production running and restore reliable employment in Hamilton and Nanticoke.
