Thousands of Canadian autoworkers have delivered an unmistakable message to Stellantis: protecting jobs and securing the future of Ontario’s automotive industry must remain central to contract negotiations.
On October 19, Unifor announced that 97.3% of participating Stellantis workers had voted to authorize strike action if necessary, following weeks of stalled negotiations. The overwhelming result comes as uncertainty deepens around the automaker’s Brampton Assembly Plant, while additional production shutdowns threaten employment stability in Windsor.
The vote does not mean workers are immediately walking off the job. However, it significantly strengthens the union’s bargaining position during an increasingly difficult period for Canadian automotive manufacturing.
With more than 9,000 unionized Stellantis employees covered by negotiations, the outcome could have consequences extending well beyond factory gates, affecting suppliers, local businesses and communities dependent on automotive production.
Stellantis Workers Deliver an Overwhelming 97.3% Strike Mandate
Unifor members employed by Stellantis voted overwhelmingly in favour of authorizing potential strike action, with 97.3% of participating workers supporting the measure. The vote took place on October 17 and 18, with results announced the following day. According to Unifor’s 2026 bargaining information, the union represents approximately 9,140 Stellantis members across Canada, including workers in vehicle assembly, casting, distribution and related operations. The 97.3% figure represents those who participated in the ballot, rather than every employee represented by the union.
The result gives Unifor’s bargaining committee substantial support as negotiations with Stellantis remain unresolved. National president Lana Payne said members were demonstrating their determination to secure an agreement protecting Canadian automotive jobs. The union’s Stellantis master bargaining chairperson, James Stewart, also emphasized that workers were prepared to defend the company’s Canadian manufacturing footprint. Although the vote demonstrates considerable solidarity, it does not guarantee a work stoppage. Instead, it gives union leadership additional bargaining leverage while both sides consider whether a negotiated settlement remains possible.
A Strike Authorization Does Not Mean Workers Are Walking Out Immediately
Despite the decisive vote, Stellantis employees are not currently in a legal position to strike. Unifor confirmed on October 19 that neither the union nor the company had requested a no-board report, a necessary step in Ontario’s collective bargaining process. The previous collective agreement expired on September 20, but its expiration does not automatically permit a strike. Ontario labour law also requires conciliation procedures and a waiting period before a legal work stoppage can begin.
Under the province’s Labour Relations Act, a strike can generally begin on the 17th day after the minister releases a no-board notice, provided the other legal requirements have been satisfied. The union must also secure majority support through a valid strike vote, a condition Stellantis members have now met. Consequently, there is no confirmed strike date, and negotiations could resume before workers become eligible to walk out. The distinction matters for employees, suppliers and customers because a strike authorization signals a potentially serious labour dispute without establishing that production will necessarily stop because of job action.
Brampton Assembly Plant Becomes the Biggest Obstacle in Negotiations
At the centre of the dispute is Stellantis’ long-idled Brampton Assembly Plant, where approximately 2,200 Unifor members remain on indefinite layoff. The facility stopped producing vehicles in late 2023 and was expected to undergo extensive modernization before returning to production. Retooling began in 2024, but the company subsequently paused the project as its North American manufacturing strategy changed. Workers who expected the shutdown to lead to new vehicle production have instead faced an extended period of uncertainty.
The situation became considerably more contentious after Stellantis announced plans in October 2025 to shift future Jeep Compass production from Brampton to its Belvidere facility in Illinois. That decision undermined expectations that Brampton would resume manufacturing under a new vehicle program. Unifor argues that Stellantis made commitments to workers and governments that should not be abandoned because of changing commercial priorities. The company has pointed to difficult market conditions and tariffs when explaining its North American investment decisions. For affected Brampton employees, the central concern remains whether their automotive careers will have a future at the facility.
Proposed Sale to Roshel Raises Questions About Thousands of Jobs
Negotiations deteriorated further after Stellantis confirmed on September 11 that it had signed a memorandum of understanding with Canadian armoured-vehicle manufacturer Roshel concerning a potential sale of the Brampton factory. Stellantis Canada president Trevor Longley presented the arrangement as a possible way to restore sustainable manufacturing activity at the idle facility. Roshel has proposed developing a defence manufacturing centre and says its plans could eventually bring more than 2,000 jobs to the site, including opportunities for workers previously employed by Stellantis.
However, the proposed sale remains fundamentally different from restoring automotive assembly operations under Stellantis. Roshel has indicated that laid-off Unifor workers would receive first consideration for certain positions, but such commitments do not guarantee that all former employees will return at comparable wages, benefits or seniority. The company’s expansion ambitions also depend partly on future business opportunities, including government defence procurement. Unifor has rejected the idea that defence manufacturing automatically provides an equivalent replacement for vehicle assembly. The dispute therefore concerns more than whether an industrial building remains occupied: it involves the type, stability and long-term economic value of the employment created there.
Windsor Assembly Workers Face Three More Weeks of Production Shutdowns
While Brampton’s future dominates negotiations, Stellantis employees in Windsor are dealing with another immediate challenge. The automaker announced that production at Windsor Assembly would be suspended during the weeks of October 19, October 26 and November 2. Unifor Local 444 said the company cited tariffs and production volumes as reasons for the additional downtime. The shutdowns follow earlier interruptions at the plant, which manufactures vehicles including the Chrysler Pacifica, other Chrysler minivans and the Dodge Charger.
Unifor’s bargaining figures list approximately 6,400 members associated with Windsor Assembly, including related transportation operations. For workers affected by temporary shutdowns, even a scheduled interruption can make household financial planning more difficult. Income arrangements vary according to individual circumstances and applicable agreements, while uncertainty over future production complicates longer-term decisions. The shutdowns are separate from the strike authorization vote and should not be confused with union-initiated job action. Nevertheless, they reinforce concerns about whether Stellantis can maintain consistent production levels in Canada while adjusting its North American operations to consumer demand and trade restrictions.
Etobicoke and Parts Distribution Workers Are Also Watching Closely
The negotiations extend beyond Stellantis’ two best-known Ontario assembly plants. Unifor’s 2026 bargaining figures identify approximately 240 members at the Etobicoke Casting Plant, which produces cast components used across Stellantis’ North American manufacturing operations. The union also represents workers at parts distribution facilities, including approximately 100 members in Mississauga and 30 in Red Deer, Alberta. These employees perform different jobs from vehicle assemblers, but their employment prospects remain tied to Stellantis’ broader manufacturing and parts-distribution network.
This interconnected structure explains why the union has insisted that negotiations address more than Brampton. Components manufactured at one location can support production elsewhere, while distribution centres depend on continued demand for vehicle parts and service products. Changes in assembly volumes may therefore create uncertainty throughout the organization, even at facilities not directly targeted for closure. In September, Unifor said Stellantis had not adequately confirmed future production plans for Windsor Assembly and Etobicoke Casting. For these workers, a satisfactory collective agreement must offer more than improvements to current compensation. It also needs to provide credible reasons to believe their facilities will continue receiving work.
Ford and GM Agreements Put Additional Pressure on Stellantis
Stellantis is the final member of Detroit’s three major automakers to complete this year’s Canadian labour negotiations. Unifor already negotiated and ratified agreements with Ford and General Motors, establishing an economic framework it expects Stellantis to follow. Ford workers approved a three-year agreement in July that provides annual wage increases of 3%, improved pension and benefit provisions, renewed cost-of-living protections and additional job-security measures. Eligible employees will also receive a C$10,000 productivity and quality bonus.
General Motors workers ratified their agreements in August, securing similar wage improvements alongside manufacturing investment commitments exceeding C$1 billion. Those arrangements include future production plans for Oshawa and St. Catharines, although challenges remain at GM’s idled CAMI facility in Ingersoll. Unifor has accused Stellantis of making its acceptance of the established economic pattern conditional on closing and selling Brampton. That position has created a major obstacle because the union wants compensation improvements and job security addressed together. The existing Ford and GM settlements demonstrate that agreements are possible during difficult industry conditions, but Stellantis’ unresolved plant commitments make its negotiations more complicated.
U.S. Tariffs Are Making Canadian Auto Production Harder to Protect
The dispute is unfolding during a prolonged period of uncertainty in Canada-U.S. automotive trade. Canada’s federal government estimates that more than 90% of Canadian-made vehicles and approximately 60% of domestically manufactured automotive parts are exported to the United States. Since April 2025, Canadian-produced vehicles have faced a 25% U.S. tariff on applicable non-U.S. content, although qualifying American content receives different treatment under the trade rules. Those policies have complicated manufacturers’ decisions about where to locate production and how to manage cross-border supply chains.
Stellantis’ latest operating figures illustrate the wider pressure. On October 13, the company reported that North American vehicle shipments had declined 12% year over year during the third quarter of 2026, falling to approximately 357,000 units. The manufacturer attributed much of that decline to planned production shutdowns affecting Jeep models, including the Grand Cherokee and Compass. The figures do not establish that tariffs alone caused the reduction, but they demonstrate the operational challenges facing the company. Meanwhile, European shipments increased 10%, highlighting the different conditions influencing Stellantis’ regional strategies. For Canadian workers, those decisions have significant implications for future vehicle allocations and employment security.
Government Funding Makes Brampton’s Future a Public Accountability Issue
The proposed Brampton sale has also renewed questions about taxpayer-supported automotive investments. In May 2022, Stellantis announced a C$3.6 billion investment program intended to modernize its Windsor and Brampton facilities and support electrified vehicle production. The federal government committed up to C$529 million toward the initiative, while Ontario pledged up to C$513 million. These were announced funding commitments subject to applicable conditions, not evidence that every dollar was disbursed. At the time, the investments were presented as a way to secure manufacturing jobs and strengthen Canada’s automotive future.
The relocation of planned Jeep production to Illinois, followed by the proposed sale of Brampton, has intensified scrutiny of those earlier promises. In September, Unifor president Lana Payne wrote to federal Industry Minister Mélanie Joly requesting clarification about Ottawa’s involvement in the Roshel discussions and whether a sale would satisfy Stellantis’ contractual obligations. Joly has publicly pressed the automaker to establish another vehicle program in Brampton and warned that Ottawa could pursue repayment if commitments are not honoured. Whether specific contractual remedies apply depends on the agreement’s terms and government enforcement decisions. For taxpayers and workers alike, the dispute raises a significant question about how public investment commitments should be enforced when corporate manufacturing plans change.
Ontario Communities Could Feel the Effects Beyond Factory Gates
Automotive manufacturing supports considerably more employment than the workers assembling vehicles. Federal industry data indicates that Canada’s automotive sector contributed approximately C$16.8 billion to national GDP in 2024, directly employed more than 125,000 people and supported over 427,000 indirect jobs. The wider industry includes hundreds of parts manufacturers alongside transportation providers, engineering businesses, maintenance contractors and other services. Although these are national figures rather than estimates of jobs specifically threatened by Stellantis, they demonstrate why assembly decisions can have consequences throughout the industrial economy.
In communities such as Brampton and Windsor, automotive employment also supports spending at neighbourhood businesses and creates demand for specialized skills. A worker on indefinite layoff may delay purchasing a vehicle or renovating a home, while a supplier facing unpredictable orders may postpone hiring or equipment investment. These are potential economic consequences rather than measured losses directly attributable to the current strike vote. Their importance helps explain why municipal leaders, provincial officials and Ottawa have become involved in the dispute. The outcome could influence not only individual Stellantis employees but also confidence in Ontario’s long-term ability to attract and retain major automotive investments.
The Next Steps Will Determine Whether Stellantis Can Avoid a Strike
Despite the overwhelming authorization vote, both sides continue to leave open the possibility of a negotiated settlement. Unifor has said strike action would be a last resort and maintains that an acceptable agreement is possible if Stellantis honours its commitments to Canadian workers. The automaker has likewise stated that it is prepared to return to bargaining in good faith while seeking an agreement compatible with the long-term competitiveness of its Canadian operations. As of the October 19 announcement, neither side had initiated the no-board process needed to advance toward a legal strike.
The most important developments will involve whether bargaining resumes, how Stellantis addresses the proposed Brampton sale and what commitments emerge concerning future production at Windsor and Etobicoke. Ottawa’s response to the company’s investment obligations could also shape the negotiations. A strike mandate gives workers leverage, but it cannot by itself secure new vehicle programs or guarantee employment for those already laid off. For thousands of Canadian families, the larger objective remains straightforward: a stable agreement that provides both fair working conditions today and credible opportunities to keep building vehicles and automotive products in Canada tomorrow.
