What began as a dispute over production at a century-old Ontario steelmaker has become a test of how far Ottawa is willing to go when a foreign buyer is accused of breaking promises made to win approval for a takeover. On October 22, Industry Minister Mélanie Joly gave Cleveland-Cliffs 15 days to address alleged violations tied to its 2024 purchase of Stelco, including employment commitments, after the company moved ahead with layoffs affecting up to 500 workers in Hamilton and Nanticoke. Cleveland-Cliffs insists the cuts are a response to a steel market reshaped by U.S. tariffs and heavy imports into Canada. Ottawa says the commitments remain binding. With court action, daily penalties and even a forced sale now on the table, the Stelco fight has moved from a labour dispute into a broader confrontation over tariffs, foreign investment and Canadian industrial policy.
Ottawa Turns a Warning Into a Formal 15-Day Demand
Ottawa’s latest move is more serious than its first warning to Cleveland-Cliffs. Earlier in October, Joly gave the company five business days to explain how it would comply with the undertakings attached to the Stelco acquisition. Cleveland-Cliffs responded by defending the layoffs and rejecting the government’s interpretation. The October 22 letter escalates the dispute into a formal 15-day demand under the Investment Canada Act, with Joly alleging failures involving six binding commitments. The government is no longer simply asking why the layoffs are happening; it is demanding that the company remedy alleged breaches, demonstrate that it remains compliant or justify any non-compliance.
That distinction matters because a demand under the Act can become the bridge to court enforcement. Ottawa has accused Cleveland-Cliffs of continuing with steps that could affect up to 500 employees even after repeated warnings. Cleveland-Cliffs, meanwhile, has not accepted the premise that temporary or indefinite layoffs automatically violate the agreement. The next stage therefore turns on evidence: employment levels, the wording of the undertakings, the company’s market justification and whether Ottawa can convince a court that the commitments are being broken rather than merely strained by changing conditions.
The Takeover Came With Specific Employment Floors
The employment promises at the centre of the confrontation were made when Cleveland-Cliffs bought Stelco in a deal valued at roughly C$3.4 billion. Ottawa approved the transaction in October 2024 after an Investment Canada Act review, subject to five-year undertakings. At the time, the government publicly said Cleveland-Cliffs would continue to employ at least the same number of unionized workers and the vast majority of non-union workers. The more precise numbers were not disclosed publicly until the new dispute: the annual average of unionized full-time-equivalent employment is to be no lower than 1,766, while salaried employment is to average at least 603.
Those figures are crucial because they make the case more complicated than a simple “no layoffs” promise. The commitments are expressed as annual-average employment floors, not a requirement that staffing remain identical every day. Stelco has seized on that wording, arguing that layoffs do not necessarily mean it will fail the annual test. Ottawa says Cleveland-Cliffs has already failed to comply or has made decisions that will inevitably put it offside. That disagreement is likely to become one of the core legal questions if the dispute reaches court.
The 500-Job Fight Is Really About Two Different Stelco Operations
The headline number is up to 500 affected workers, but the operational story is split between two very different Stelco sites. Hamilton Works is the company’s finishing hub, where steel is cold-rolled and coated, including galvanized products used in automobiles, appliances, agriculture and construction. Lake Erie Works in Nanticoke produces hot-rolled steel and remains the centre of Stelco’s primary steelmaking. Cleveland-Cliffs announced in late September that it would indefinitely idle cold-rolled and coated operations in Hamilton and concentrate more activity at Lake Erie Works, with the wind-down beginning in October.
For workers, the corporate language translates into a much more immediate question: whether a transfer, recall or long period without normal wages follows a layoff notice. The union representing Hamilton workers initially estimated roughly 350 jobs there would be affected, while additional reductions were expected at Lake Erie Works. Cleveland-Cliffs has said job opportunities would be offered to some Hamilton employees in Nanticoke and that total Stelco production tonnage would be maintained. The union has been far less confident that enough positions exist to absorb everyone, leaving families to navigate uncertainty even as the company describes the restructuring as temporary and reversible if market conditions improve.
Cleveland-Cliffs Says the Market for Hamilton Steel Has Collapsed
Cleveland-Cliffs has built its defence around a sharp deterioration in the market for the products made on the idled Hamilton lines. In an October response to Joly, Stelco president Paul Simon said Canadian exports of cold-rolled and coated steel to the United States had fallen 58 per cent from pre-trade-war levels. He put the decline at about 226,000 tonnes in the second quarter of 2026 compared with the 2024 quarterly average. The company also said imports still held roughly 45 per cent of the Canadian market for those products, despite government efforts to limit trade diversion.
The company’s argument is that the problem is not simply lower sales to the United States. It says weaker Canadian demand and continued foreign imports have combined to remove more than one million tonnes of annual market opportunity for the types of steel processed in Hamilton—roughly twice the plant’s historical annual output of cold-rolled and coated steel. Earlier employee communications said demand in Stelco’s traditional markets was nearly 25 per cent below the 2024 quarterly average in the second quarter of 2026, including a 10 per cent decline in Canada. Cleveland-Cliffs therefore wants tighter import protection, arguing that financial assistance alone cannot create customers for galvanized steel.
Ottawa Says Cleveland-Cliffs Helped Create the Tariff Problem It Now Blames
Ottawa’s sharpest rebuttal is that Cleveland-Cliffs cannot comfortably portray U.S. tariffs as an uncontrollable shock while its own chief executive publicly supported protectionist policies. President Donald Trump raised U.S. Section 232 tariffs on many steel and aluminum imports from 25 per cent to 50 per cent in June 2025, while subsequent 2026 changes kept steel-related duties as high as 50 per cent. Those measures hit Canadian producers that had long relied heavily on access to the American market. Cleveland-Cliffs says that trade rupture fundamentally changed the assumptions behind its 2024 purchase of Stelco.
Joly argues the company’s own advocacy weakens that defence. In written testimony to a U.S. congressional steel caucus in January 2026, Cleveland-Cliffs CEO Lourenco Goncalves said his company had blocked Stelco from selling steel into the U.S. market and welcomed the prospect of a breakdown in the North American trade framework. His message was explicit: “We need manufacturing in the United States. Not in Canada; not in Mexico.” Ottawa says that stance conflicts with Cleveland-Cliffs’ commitment to support policies benefiting the Canadian steel business. Cleveland-Cliffs disputes that its advocacy or the layoffs amount to a breach, setting up a politically charged argument over what counts as a circumstance beyond an investor’s control.
A Forced Sale Is Possible, but Ottawa Cannot Simply Order One
The threat of a forced sale sounds dramatic, but it is not something Ottawa can impose by declaration. The Investment Canada Act lays out a staged enforcement process. When the minister believes a foreign investor has failed to honour a written undertaking, Section 39 allows the government to issue a demand requiring the investor to stop the alleged contravention, remedy the default, show that no breach exists or justify non-compliance. Joly’s 15-day letter is significant because it places the Stelco dispute squarely inside that enforcement framework rather than leaving it as political pressure.
If Cleveland-Cliffs does not satisfy the demand, the government may apply to a superior court under Section 40. A judge would then have to decide whether the minister was justified in issuing the demand and whether the company failed to comply with it. The court can order compliance with undertakings, direct divestiture of control of the Canadian business, restrict voting rights, require disposition of assets or impose a penalty of up to C$10,000 for each day of contravention under the provision Ottawa has cited. In other words, a forced sale is legally possible, but only after a court process; it is not the automatic result of missing the 15-day deadline.
Strong Earnings Complicate the Argument Over What Stelco Can Afford
The dispute is especially striking because Cleveland-Cliffs is not presenting Stelco as a business collapsing across the board. Three days before Joly’s latest demand, the parent company reported third-quarter revenue of US$5.6 billion, GAAP net income of US$165 million and adjusted EBITDA of US$612 million. Cleveland-Cliffs called the quarter its strongest in three years. Goncalves also said Stelco itself had recorded its strongest quarter since the 2024 acquisition, helped by an improved Canadian market for hot-rolled steel that made the subsidiary a positive contributor to EBITDA.
That does not eliminate the company’s argument about galvanized steel, but it narrows it. Cleveland-Cliffs says the hot-rolled side of Stelco is improving while the market for galvanized products remains oversupplied and commercially unsustainable. Management has said total Stelco tonnage can be maintained by focusing on products with demand and that roughly 2,000 Canadian jobs are being preserved. For laid-off workers, however, the distinction between a profitable parent, a stronger hot-rolled business and a weak finishing market offers little immediate comfort. It also gives Ottawa a powerful political line: the disagreement is not simply about whether Stelco can survive, but about which operations and jobs a foreign owner is obligated to maintain after making binding commitments to Canada.
The Stelco Clash Is Now Part of a Multibillion-Dollar Canadian Steel Strategy
The Stelco ultimatum landed one day after Ottawa and Ontario unveiled a C$8.7-billion package aimed at industries facing U.S. trade pressure, making the confrontation part of a much larger steel strategy. The plan includes a Joint Steel Action Fund with C$3.55 billion committed by the federal government and C$1.67 billion by Ontario over five years. Governments say the money will help mills upgrade equipment, make more of the specialized steel Canadian industries need, diversify into non-U.S. markets and supply major infrastructure, defence, manufacturing and energy projects.
The strategy also leans on Buy Canadian and Buy Ontario procurement rules, stronger enforcement against dumping and a federal-provincial steel task force. Ottawa says Canada’s steel industry supports more than 23,000 direct jobs and is connected to roughly 172,000 jobs in fabricated metals. Prime Minister Mark Carney has also noted that Canada imports more than 6.5 million tonnes of steel a year, arguing domestic mills should capture more of that demand. Against that backdrop, the Stelco fight becomes a test of whether public money, procurement policy and import restrictions can stabilize the sector while Ottawa simultaneously enforces promises made by a foreign owner.
Stelco’s History Shows Why the 15-Day Deadline May Only Be the Beginning
Stelco has been here before, under a different American owner. U.S. Steel acquired Stelco in 2007 and made Investment Canada Act commitments involving production and employment. After layoffs and shutdowns during the global financial crisis, Ottawa issued a formal demand in May 2009 and went to Federal Court that July, alleging the company had failed to meet its undertakings. The litigation did not produce a quick courtroom verdict. Instead, the government and U.S. Steel reached an out-of-court settlement in December 2011 with new commitments, including continued Canadian steel production, operation of the Hamilton and Lake Erie plants until 2015 and at least C$50 million in additional capital investment.
That history is both precedent and warning. It shows Ottawa can use the Investment Canada Act against a steelmaker over job and production promises, and the Federal Court upheld the legitimacy of the Act’s enforcement machinery during that earlier fight. But it also shows how slowly legal remedies can move compared with a worker’s paycheque. The current government has compressed the early stages by issuing repeated demands within weeks of the 2026 layoffs. Whether that pressure produces recalled workers, a negotiated restructuring or another long court battle will determine whether the 15-day ultimatum is remembered as a turning point or simply the opening move in a much longer contest.
