The clock has run out on Unifor’s collective agreement with Stellantis, but the expiry has not produced an immediate walkout. The contract covering more than 9,000 Stellantis workers in Canada expired at 11:59 p.m. on September 20, 2026, with bargaining still deadlocked over the future of the company’s idled Brampton Assembly Plant.
For roughly 2,200 laid-off Brampton workers, the dispute is about considerably more than wages. Stellantis is pursuing a potential sale of the factory to Canadian armoured-vehicle manufacturer Roshel, while Unifor is demanding a solution that preserves automotive assembly. Despite the contract expiry, the union says it is not yet legally able to strike because Ontario’s mandatory conciliation process has not been completed. That leaves workers, Stellantis and governments in an unusual period of uncertainty: the old agreement has expired, negotiations remain unresolved, but a legal work stoppage is not yet on the table.
Contract Expiry Raises the Pressure Without Automatically Starting a Strike
The September 20 expiry is an important bargaining milestone, but Ontario labour law does not allow unionized workers to strike simply because their collective agreement has ended. Unifor told Stellantis members before the deadline that the union and company remained in conciliation, a mandatory process designed to give both sides another opportunity to reach an agreement. The union therefore would not be in a legal strike position when the agreement expired. That distinction matters for thousands of employees who might otherwise have expected picket lines as soon as the deadline passed.
Ontario’s process contains several additional steps. If conciliation fails, the Ministry of Labour can issue what is commonly called a “no-board” notice. A legal strike or lockout generally cannot begin until the 17th day after that notice is released. The union must also conduct a strike vote, with more than half of participating employees voting in favour. Unifor has said strike votes would be the next step if it decides escalation is necessary. Until those requirements are met, contract expiry increases bargaining pressure without creating an immediate legal walkout.
Brampton Has Become the Central Obstacle to a New Agreement
Brampton Assembly has transformed what might normally be a negotiation over wages, benefits and workplace rules into a much larger argument about whether Stellantis will continue assembling vehicles at the site. Approximately 2,200 Unifor Local 1285 members have been on indefinite layoff after production stopped in December 2023. The factory had been scheduled for extensive retooling ahead of a new generation of Jeep production, giving workers an expectation that the shutdown was temporary rather than the beginning of a permanent exit.
Those expectations changed dramatically. Stellantis paused Brampton retooling work in February 2025 amid uncertainty surrounding its North American product strategy. Later that year, the company announced a major U.S. manufacturing expansion that included reopening its Belvidere, Illinois, plant for Jeep Cherokee and Compass production. By the 2026 bargaining round, Unifor said Stellantis was seriously considering closing and selling Brampton. The union subsequently declared that it would not accept a tentative national agreement unless there was a suitable resolution for the Brampton workforce, making the plant’s future the decisive issue separating the two sides.
The Roshel Deal Changed the Stakes of the Negotiations
The dispute intensified when Stellantis confirmed that it had signed a memorandum of understanding with Roshel covering a potential sale of the Brampton factory. Roshel is a Canadian manufacturer of armoured vehicles and has proposed establishing a defence-manufacturing operation at the site. Stellantis has described the company as a potential path toward restoring sustainable industrial activity in Brampton and avoiding an extended period in which a large manufacturing complex sits unused.
There is an important distinction, however: a memorandum of understanding is not the same as a completed sale. The potential transaction remains the subject of intense opposition from Unifor, which argues that replacing a high-volume auto assembly operation with another type of manufacturing would fundamentally alter the economic role of the plant. Roshel, for its part, has said it is prepared to give laid-off Unifor workers first consideration for jobs and could begin returning some employees to work. That prospect offers one possible future for the facility, but it has not satisfied a union whose bargaining position is centred on preserving automotive assembly in Brampton.
Unifor Is Tying the National Deal Directly to Brampton
Unifor’s position means the Brampton dispute cannot easily be separated from wages and benefits for employees at Stellantis operations elsewhere in Canada. After 10 days of intensive bargaining, the union declared an impasse on September 11 and paused formal talks. It said Stellantis had offered only conditional agreement with the economic pattern established earlier in negotiations with Ford and General Motors, with that position connected to the proposed closure of Brampton.
That pattern is valuable to Stellantis workers because the 2026 Ford and GM agreements include three per cent general wage increases in each year of their three-year contracts, along with cost-of-living provisions, bonuses, pension and benefit improvements and various investment commitments. Under Unifor’s traditional Detroit Three bargaining strategy, terms negotiated with the first automaker become the economic benchmark for the others. But the Stellantis round illustrates why pattern bargaining is not simply a matter of copying wage numbers. For Brampton members facing indefinite layoffs and a possible factory sale, employment security and future product commitments may carry as much weight as the size of the next pay increase.
Laid-Off Brampton Workers Have Been Given an Income-Security Extension
One immediate concern surrounding the contract deadline was what would happen to income protections for Brampton employees who remain laid off. Unifor announced before the expiry that it and Stellantis had agreed to extend existing income-security provisions covering Local 1285 members. Those protections stem from a December 2025 letter of agreement and had become particularly important because the plant remained without normal vehicle production while bargaining approached its deadline.
Under the extension, the provisions remain in place until the parties reach a legal strike or lockout position or until a renewed collective agreement takes effect, whichever comes first. For affected households, that creates at least a temporary bridge through the unusual period between contract expiry and a possible labour confrontation. It also illustrates how different the Brampton situation is from a conventional operating-plant negotiation. Thousands of employees are not deciding whether to leave active assembly lines during a strike. Many are already waiting to learn whether those assembly jobs will return at all, meaning bargaining is taking place against the backdrop of employment uncertainty that began years before the current contract expired.
Workers in Windsor and Etobicoke Also Have a Stake in the Outcome
Brampton dominates the negotiations, but the Stellantis agreement covers more than one Ontario factory. Unifor represents more than 9,000 Stellantis employees across Canada, and the union entered bargaining seeking production certainty at Windsor Assembly and Etobicoke Casting as well as a solution for Brampton. When talks reached an impasse, Unifor said Stellantis had yet to confirm forecast production plans for those operations, adding another layer of uncertainty to the negotiations.
Windsor remains a major Stellantis manufacturing centre, producing vehicles including the Chrysler Pacifica and related models, while Etobicoke supplies cast components used in automotive production. A national Stellantis work stoppage, if one eventually becomes legal and is authorized by members, could therefore reach beyond Brampton and affect active parts of the company’s Canadian manufacturing network. That gives the unresolved dispute broader industrial significance. Employees working regular shifts in Windsor or Etobicoke may have different immediate circumstances from laid-off Brampton members, but they bargain under the same broader framework. The eventual settlement will help determine wages and benefits while also signalling how much future manufacturing certainty Stellantis is prepared to provide at its remaining Canadian operations.
Government Agreements Have Made the Plant’s Future a Public Issue
Brampton’s future is also complicated by years of public support intended to secure automotive manufacturing investment. In 2022, Stellantis announced a $3.6-billion plan to modernize its Windsor and Brampton plants and expand Canadian research and development. Ontario committed up to $513 million toward the broader package, with matching federal support. A later Canada-Ontario agreement connected to Stellantis and LG Energy Solution incentives explicitly stated that Stellantis would uphold existing Canadian commitments, including a production mandate at Brampton.
Those conditions help explain why the potential factory sale has attracted attention far beyond the bargaining table. Federal Industry Minister Mélanie Joly has publicly said the government expects Stellantis to honour its commitments and has raised the possibility of recovering public money if vehicle production is not restored. Ottawa had already taken action in 2025 after Stellantis cancelled its Brampton production plans, reducing the company’s annual tariff-remission quota by 50 per cent. The disagreement therefore touches three overlapping relationships: Stellantis with its workforce, Stellantis with governments that supported Canadian investment, and Canada with an auto industry increasingly shaped by cross-border incentives and trade policy.
Stellantis Says Trade and Market Conditions Changed the Business Case
Stellantis argues that its Brampton decisions cannot be viewed separately from major changes in the North American automotive market. Company officials have pointed to unpredictable trade conditions, regulatory pressures and affordability challenges while explaining why the original Brampton business case changed. The uncertainty became particularly visible in early 2025, when retooling for the next-generation Jeep Compass was paused amid concerns about U.S. tariffs on vehicles and parts imported from Canada and Mexico.
The company’s subsequent U.S. expansion sharpened the contrast. In October 2025, Stellantis announced a $13-billion investment plan intended to increase its U.S. manufacturing footprint and finished-vehicle production. The plan included more than $600 million to reopen Belvidere Assembly in Illinois, with Jeep Cherokee and Compass production expected to create roughly 3,300 jobs. Those decisions are central to Unifor’s frustration because workers in Brampton had previously been preparing to build the Compass themselves. From Stellantis’s perspective, production allocations respond to rapidly changing commercial conditions. From the union’s perspective, those same decisions demonstrate why binding product commitments have become essential to employment security in Canadian auto bargaining.
The Next Deadline Will Matter More Than the One That Just Passed
With the collective agreement now expired, attention shifts from September 20 to the labour-law process that could eventually produce a real strike deadline. Conciliation can still result in a negotiated settlement. If it does not, the release of a no-board notice would begin Ontario’s statutory countdown toward a possible legal work stoppage. Unifor would also need to conduct strike votes and receive majority support among those voting before members could legally strike.
That means the situation can change quickly without changing immediately. A tentative agreement could still emerge before a strike becomes legal, particularly if Stellantis, Unifor and governments find a formula for dealing with Brampton. Alternatively, completion of conciliation and successful strike votes would substantially increase pressure on both sides. For now, the most important fact is that contract expiry and legal strike status are two different events. More than 9,000 Stellantis workers are technically past their old agreement’s expiry date, but the labour dispute remains in a procedural holding period. The central question is no longer whether the September 20 deadline passed without a deal. It is whether there is any compromise capable of resolving Brampton before the next deadline carries the possibility of shutting down Stellantis operations in Canada.
