Ottawa has given Cleveland-Cliffs five business days to explain how it will honour the employment undertakings it signed to win approval for its $3.4 billion takeover of Stelco. Industry Minister Melanie Joly says the trade war is no defence.
OTTAWA and HAMILTON, Ont., Oct. 8, 2026
The federal government has opened a direct legal confrontation with the American owner of one of Canada’s largest steelmakers, arguing that the tariffs an executive publicly supported cannot now be used as the excuse for breaking a signed commitment to Canadian workers.
Industry Minister Melanie Joly said Wednesday that Stelco Holdings Inc. cannot invoke the Canada United States trade war to justify cutting jobs it promised to keep when Cleveland-Cliffs Inc. acquired the Hamilton steelmaker in 2024. Speaking in Ottawa, Joly noted that Cleveland-Cliffs chief executive Lourenco Goncalves has publicly backed American steel tariffs, and drew the obvious conclusion.
“They cannot say that this is now an act of God or force majeure,” Joly said, according to The Canadian Press. If the company does not produce an acceptable plan, she added, “we will use the full force of the law.” On the status of the undertakings themselves she was unambiguous: “These obligations are binding.”
The minister sent a letter on Monday to Stelco president Paul Simon demanding a plan showing how Cleveland-Cliffs intends to meet all of its commitments to Ottawa, including the retention of more than 1,500 jobs. The company was given five business days to respond. As of Wednesday afternoon, Ottawa said it had received no reply.
The clock is not the only thing running. Stelco’s wind down of its cold rolled and coated operations at Hamilton Works begins Friday.
What Stelco announced
The dispute traces to Sept. 29, when Stelco told employees it would indefinitely idle its cold rolled and coated lines at Hamilton Works, affecting up to 500 employees across its Hamilton and Lake Erie facilities.
A company memo obtained by CBC News, written by vice president of sales Frederic Fafard, framed the move as necessary for Stelco’s survival. The memo cited trade disruptions and described the market for these products as challenging and unsustainable. It reported that demand for cold rolled and galvanized products in the company’s traditional markets fell almost 25 per cent in the second quarter of 2026 compared with the 2024 quarterly average, and said import volumes remain high enough to prevent Stelco from filling the resulting gap. The memo attributed the situation to American tariffs.
Cleveland-Cliffs has described the decision as a consolidation rather than a contraction. Spokesperson Pat Persico said total output will not change because production is moving to Lake Erie Works in Nanticoke, Ont., and that the company expects many affected Hamilton employees to be absorbed there.
The union disputes that arithmetic. Ron Wells, president of United Steelworkers Local 1005, estimates that roughly 350 Hamilton steelworkers will be laid off. He has said the duration of the layoffs is unknown and that the timing, weeks before the holidays, is particularly hard on members. Union officials have said only about 40 laid off Hamilton workers have been offered positions at Nanticoke, a fraction of the number losing work.
Joly has said Ottawa offered Stelco financial support to avoid the cuts and that the company declined. She called the decision to reject those proposals and proceed extremely disappointing. The Ontario government has said separately that Stelco did not pursue provincial tariff relief that was available to it.
The undertakings
The legal question turns on what Cleveland-Cliffs actually signed.
The company acquired Stelco for $3.4 billion in a transaction that closed in November 2024. Because the buyer was foreign, the deal required a net benefit review under the Investment Canada Act. Approval was granted on conditions. A ministerial statement issued in October 2024 recorded the commitment that Cleveland-Cliffs would continue to employ at least the same number of unionized workers for five years, along with most non union positions. Joly has described the covered headcount as more than 1,500 jobs.
In her letter, Joly made the government’s legal theory explicit, writing that the commitments do not cease to apply simply because business strategy or market conditions have changed. That sentence is the heart of the case. Undertakings under the Investment Canada Act are contractual promises to the Crown, not projections, and the statute gives the minister enforcement tools that most Canadian business regulation does not.
If Ottawa is not satisfied with the response, the minister can apply to a superior court. The remedies available are severe. A judge can order the company to comply with its undertakings, impose substantial financial penalties, or in the most extreme case order divestiture of the Canadian business.
Lawyers who practise in the area caution that the path is neither quick nor certain. Sandy Walker of Dentons has noted that Cleveland-Cliffs could argue that factors beyond its control, namely the American tariffs, prevented it from meeting its commitments. That is precisely the defence Joly moved pre-emptively to foreclose with her act of God remark, and the reason she pointed to Goncalves’s public advocacy for the tariffs in question. A company that lobbied for a measure has a harder time characterising that measure as an external shock.
History suggests patience will be required. Ottawa’s last major enforcement action of this kind, against United States Steel Corp. over job and production commitments made when it bought the former Stelco in 2007, ran for roughly two years before settling. That case ended with a negotiated package of additional investment rather than a judicial ruling, which is the outcome most trade lawyers expect here as well.
Reaction
Blair Dickerson, president of the Canadian Steel Producers Association, framed the Stelco announcement as evidence of how difficult the tariff situation has become and how urgently a resolution is needed. The association has spent 2026 pressing Ottawa for faster relief and tighter import controls.
The United Steelworkers have taken a sharper line. Union officials have called the company’s rationale disingenuous and contradictory, pointing to the gap between Cleveland-Cliffs publicly supporting American steel tariffs and then citing those same tariffs as the cause of Canadian job losses. For Local 1005, which has represented Hamilton steelworkers through five decades of restructuring, the practical questions are duration and recall, and neither has an answer.
Hamilton politicians across party lines have pressed for federal intervention. The city’s manufacturing base has absorbed repeated shocks, and the Stelco cuts land less than a year after Algoma Steel announced layoffs affecting more than 1,000 workers in Sault Ste. Marie in December 2025.
Cleveland-Cliffs has not publicly responded to Joly’s ultimatum. The company’s position, as expressed through its spokesperson, remains that consolidation preserves output and that the Canadian footprint is being rationalised rather than reduced.
Economic impact analysis
The macroeconomic numbers explain why Ottawa is willing to escalate.
The Bank of Canada’s April 2026 assessment found that Canadian steel exports had roughly halved under the American tariff regime, a sharper contraction than any other sectoral category it tracked. The central bank also noted the structural reason the damage is politically explosive while being macroeconomically contained: industries facing sectoral American tariffs account for about 1 per cent of Canadian output and employment but roughly 15 per cent of Canadian exports. Steel is a small share of gross domestic product and an enormous share of certain communities.
Federal officials have acknowledged that they do not yet have firm numbers on tariff related steel job losses, with internal estimates running in the high hundreds and thousands of positions described as at immediate risk. Government analysis has pointed to Canadian steel doing extremely limited business with the United States and to exports likely falling by more than a million tonnes across the first two quarters of the year.
Ottawa’s response has been a layered package rather than a single measure. Counter tariffs of 25 per cent apply to American steel imports worth $12.6 billion and aluminum imports worth $3 billion. Tariff rate quotas on steel from non free trade agreement countries have been cut to 20 per cent of 2024 volumes, with free trade partners other than the United States and Mexico set at 75 per cent, and above quota imports facing a 50 per cent tariff. A 25 per cent tariff applies to steel melted and poured in China, and another 25 per cent tariff covers steel derivative products such as wind towers, prefabricated buildings, fasteners and wire.
On the support side, the $5 billion Strategic Response Fund is open to firms across tariff affected sectors, with $150 million reserved for steel producers through the Regional Tariff Response Initiative. A Buy Canadian procurement policy requires federal contracts above $25 million to prioritise Canadian steel and aluminum. Ottawa has committed to work with the railways to cut interprovincial freight rates for steel and lumber by half, and has funded reskilling for up to 50,000 workers, with more than $100 million over two years supporting Work-Sharing employers and training for as many as 26,000 workers.
For the workers at Hamilton Works, the immediately relevant measures are the employment insurance changes announced Aug. 25. Those waive the one week waiting period for another year, allow claims without first exhausting severance or vacation pay, and extend by eight months the additional 20 weeks of benefits available to long tenured workers. Regular benefits replace 55 per cent of average insurable weekly earnings to a maximum of $729 a week in 2026, which for a steelworker earning $90,000 a year covers roughly 42 per cent of gross pay. Ontario has said the Canada Ontario Workforce Tariff Response will fund retraining for 75 Hamilton area workers, a figure the union regards as inadequate to the scale of the layoff.
Under Ontario employment standards, a temporary layoff can run up to 13 weeks in a 20 week period, or up to 35 weeks in 52 where specified conditions are met. Beyond those limits the layoff is treated as a termination, triggering termination and severance entitlements. Unionized workers facing a layoff past 35 weeks under a qualifying collective agreement must generally choose between severance and recall rights rather than holding both.
Implications for importers, exporters and Canadian business
The Stelco case matters well beyond Hamilton, and for reasons that have little to do with steel.
For foreign investors, it is the clearest test in more than a decade of whether Investment Canada Act undertakings mean anything once conditions deteriorate. Every acquirer that has given employment, capital expenditure or head office commitments to secure approval is watching to see whether Ottawa litigates or settles, and on what terms. A negotiated outcome that preserves the headline job number in exchange for investment elsewhere would confirm the pattern set in 2009. A court ordered remedy would change how undertakings are priced into Canadian deals.
For Canadian steel buyers, the immediate concern is supply. The idling of cold rolled and coated capacity at Hamilton Works removes domestic availability of specific product grades at the same moment that tariff rate quotas limit substitution from offshore mills. Fabricators, appliance manufacturers, automotive stampers and construction suppliers who have been sourcing Hamilton material should be confirming grade availability at Nanticoke, testing qualification timelines for alternative mills inside the quota, and modelling the landed cost of above quota imports at the 50 per cent rate before committing to 2027 pricing.
For exporters of steel derivative products, the layered Canadian and American regimes now create genuine classification risk in both directions. Canadian derivative tariffs reach fasteners, wire and prefabricated structures, while the American full value metal tariffs introduced in April apply to the entire entered value of articles and derivatives rather than to metal content alone. A product that was marginal under the old content based calculation can be substantially more expensive under the new one. Firms that have not re-run their duty exposure since the April 6 change are likely working from stale numbers.
For employers in any tariff exposed sector, the Joly letter carries a governance message. Ottawa is signalling that it will test the causal chain between a tariff and a layoff rather than accepting it. Companies that announce trade related restructuring should expect to be asked for the underlying demand data, the alternatives considered, and the government support that was offered and declined. Stelco rejected federal financial assistance and did not pursue Ontario relief, and both facts are now part of the public record of the dispute.
Hamilton and the wider steel map
Hamilton Works is not a marginal asset. The plant is the historic core of Canadian primary steelmaking, and the cold rolled and coated lines being idled produce the flat rolled grades used in appliances, automotive stampings, construction products and the general fabrication trade. When those lines go cold, the affected grades do not simply migrate to another Canadian mill, because finishing capacity is specialised and qualification of a new supplier can take months.
The Nanticoke consolidation is therefore a partial answer at best. Lake Erie Works is a capable integrated facility, and Cleveland-Cliffs is correct that tonnage can shift. What does not shift automatically is product mix, delivery lead time and the customer qualification that sits behind every specification. Buyers who have been told that supply continues should be asking for grade level confirmation rather than tonnage level reassurance.
The broader Canadian steel map has been contracting for a year. Algoma Steel announced layoffs affecting more than 1,000 workers in Sault Ste. Marie in December 2025. Government assessments through 2026 have described Canadian producers as doing extremely limited business with the United States, with most major mills reporting steep declines in American shipments alongside production adjustments and layoffs. The Hamilton decision is the latest entry in that sequence rather than a departure from it.
Aluminum has fared better, for reasons that illustrate what protects a Canadian metals producer in this environment. Federal analysis notes that American smelting capacity can meet only about one third of United States primary aluminum demand even at full utilisation, which has kept Canadian metal flowing despite a 50 per cent duty. Steel enjoys no such structural advantage. American mills can replace Canadian tonnage, which is precisely why the tariff bites harder.
How the enforcement process is likely to unfold
Investment Canada Act enforcement is rare enough that the procedure is unfamiliar to most Canadian executives, and it is worth setting out.
The minister’s first step is the demand letter, which has been sent. The company responds, typically with a plan, a request for variation of the undertakings, or an argument that performance has been excused. The minister then decides whether to accept, negotiate, or apply to a superior court for a compliance order.
Variation is the quiet middle path and the most common resolution. Undertakings can be amended by agreement where circumstances have genuinely changed, and a negotiated amendment that trades a reduced headcount commitment for incremental capital investment, a longer commitment period, or guaranteed Canadian procurement is the outcome that most practitioners would predict. It allows both sides to claim a result.
Litigation is the alternative, and it is slow. The precedent that everyone in the file cites is Ottawa’s action against United States Steel Corp. over the commitments attached to its 2007 purchase of the former Stelco, which ran roughly two years before a settlement that produced additional investment commitments rather than a judicial determination of the law. A second multi year case would do little for the workers whose jobs are at issue this week.
The deterrent value, however, is real. Divestiture is on the statute books as a remedy, and no acquirer wants a Canadian court weighing whether to order the sale of its business. That is the leverage Joly is applying.
What other foreign acquirers should take from this
Any firm that has given undertakings to obtain Investment Canada Act approval should read the Joly letter closely, because the government has now stated its interpretive position in writing: commitments do not cease to apply simply because business strategy or market conditions have changed.
That standard is stricter than many acquirers assumed. It implies that ordinary commercial deterioration, including a tariff shock, does not discharge an undertaking, and that the bar for excuse is closer to genuine impossibility than to commercial hardship. Acquirers negotiating undertakings in the current environment should expect to fight for explicit material adverse change language rather than relying on an implied force majeure.
There is a second lesson in the Goncalves point. Public advocacy by an executive for a policy that later harms the acquired business can be used against the company when it argues that the policy was an external shock. That is an unusual intersection of government relations and investment review compliance, and it is one that boards of multinational acquirers will now need to manage deliberately.
Outlook
Cleveland-Cliffs’s five business days expire shortly, which in practice means early next week. The company has three realistic options. It can produce a plan that preserves the committed headcount, most plausibly by expanding the Nanticoke absorption well beyond the 40 positions the union says have been offered. It can negotiate a substitute package with Ottawa, trading capital investment or a longer commitment horizon for relief on the job number. Or it can refuse, and let the matter go to court.
The third path is the least likely and the most consequential. It would put the enforceability of Investment Canada Act undertakings before a judge for the first time in years, with an American owner arguing that American tariffs its own chief executive championed constitute circumstances beyond its control.
Whatever the company decides, the layoffs at Hamilton Works begin Friday. For the roughly 350 steelworkers the union expects to lose their jobs, the legal question of whether those cuts were permitted will be settled long after the lines have gone cold.
