Unifor Members Back Stellantis Strike Mandate as Canada Talks Stall Over Brampton Plant
Unifor members at Stellantis in Canada have voted 97.3% in favor of authorizing strike action, the union said Oct. 19, 2026, after two days of voting on Oct. 17 and 18. The mandate gives the union's bargaining committee the power to call a strike against the Chrysler, Jeep and Dodge maker if talks fail. Negotiations have been stalled for more than a month over the future of the idled Brampton Assembly Plant in Ontario, which Stellantis has said it is considering closing and selling to defense contractor Roshel.
Key developments
- Unifor reported a 97.3% vote in favor of a strike mandate across its Stellantis locals, with balloting held Oct. 17-18 and results released Oct. 19.
- The union said it is not yet in a legal strike position because neither side has requested a "No Board" report, a required step under Canadian labor law before job action.
- Talks covering more than 9,000 workers opened Sept. 1. The previous collective agreement expired at 11:59 p.m. on Sept. 20 without a tentative deal.
- Unifor said Stellantis has tied its offer on the core economic pattern to an agreement to close and sell the Brampton plant, and has signed a memorandum of understanding with Roshel, which has expressed interest in buying the site.
- The vote statement was signed by Unifor National President Lana Payne, Stellantis Master Bargaining Committee Chairperson James Stewart and Vice-Chairperson Vito Beato.
How the dispute reached this point
Unifor bargains with the Detroit Three in sequence. This year it reached a deal with Ford Motor Co. first, which members ratified on July 19, and then with General Motors, ratified on Aug. 30. The union opened talks with Stellantis on Sept. 1, aiming to settle on the same economic pattern. That approach broke down on Sept. 11, when Unifor said 10 days of intensive bargaining had ended in an impasse and paused formal talks.
The sticking point is Brampton. According to Unifor, Stellantis backed away in October 2025 from a commitment to invest in Jeep production at the plant, partly in response to tariffs, and moved Jeep Compass production to the United States. The Canadian Press, as carried by BNN Bloomberg, reported that Compass output went to Illinois and that more than 2,000 workers were laid off when Brampton stopped production in 2023. On Aug. 12, 2026, Stellantis told the union it was seriously considering closing the plant and selling it to a third party.
The Canadian Press also reported that Roshel plans defense manufacturing and automotive production in Brampton involving more than 2,000 jobs. Stellantis has said market and trade conditions undermined the plant's original business case and that it remains committed to bargaining in good faith, according to the same reports.
Industry implications
A strike mandate does not mean a walkout, and Unifor stressed that point in its release, describing strike action as a last resort. The vote still changes the bargaining dynamic. It shows the company that the membership is backing the committee's refusal to accept a settlement without what the union calls a suitable resolution for Local 1285 members at Brampton.
The dispute also tests how far a pattern agreement can stretch when one automaker's footprint plans diverge from its rivals. Ford and GM settled without strike votes. Stellantis is the only Detroit Three company where Unifor says the economic offer has been made conditional on a plant closure. That makes this round less about wages and more about whether Canadian assembly capacity is preserved, repurposed or sold.
The Roshel proposal adds a new element. A defense manufacturer taking over an auto assembly site would keep industrial activity in Brampton but would move the facility out of the vehicle production network that Unifor's contracts are built around.
Competitive and supply chain implications
Windsor Assembly Plant is the most exposed site in any work stoppage. Unifor Local 444 represents more than 6,400 workers there, and the plant builds the Chrysler Pacifica, Chrysler Voyager, Grand Caravan and Dodge Charger, according to The Canadian Press as published by CP24. A halt at Windsor would interrupt output of those models and ripple back to the parts suppliers that feed the plant.
The bargaining unit also includes the Etobicoke Casting Plant and parts distribution centers in Mississauga, Ontario, and Red Deer, Alberta. Unifor said Stellantis has not confirmed forecast plans for Windsor Assembly or Etobicoke Casting. The union is seeking binding protections for Windsor, including its third shift, according to CP24's report. For suppliers, uncertainty over Brampton has lingered since 2023. Unifor's Sept. 16 letter to the federal industry minister said a closure would affect hundreds of supplier firms.
Regional implications
The dispute has drawn in Ottawa. In a Sept. 16 letter to Industry Minister MĂ©lanie Joly, Unifor argued that the Roshel memorandum breaches Stellantis's commitment to the federal government to maintain its full Canadian production footprint. The letter referenced a formal dispute and notice of default served in December 2025 and asked whether the government is a party to the memorandum, whether officials have expressed support for the sale and what other options Stellantis presented. It also said a lobby firm representing Roshel met ministry staff several times in August.
For Ontario, the stakes extend beyond a single plant. Windsor and Brampton are Stellantis's two Canadian assembly plants, and the union has argued there is no economic substitute for auto assembly jobs in Canada. Any settlement that confirms Brampton's exit from vehicle production would leave Stellantis with one Canadian assembly plant.
Credence Research analysis
The 97.3% result is a signal of leverage, not an imminent shutdown. Because no "No Board" report has been requested, a legal strike is still at least one procedural step away, which gives both sides time to return to the table. The union has framed the vote as a tool to reach an agreement, and Stellantis has publicly stated its commitment to continued bargaining. The more consequential variable is the federal government's position on the Brampton sale, because Unifor has tied the labor contract directly to Ottawa's earlier agreements with the automaker.
The broader takeaway for the North American auto sector is that tariff-driven footprint decisions are now flowing directly into labor contracts. Stellantis's 2025 shift of Compass production to the United States is the root of this dispute. Automakers rebalancing production across the border can expect unions and governments to treat investment commitments as enforceable terms rather than intentions, and suppliers tied to Canadian plants face extended planning uncertainty until those commitments are settled.
What comes next
- Resumption of formal bargaining between Unifor and Stellantis, which the union paused in September pending a Brampton resolution.
- Any request by either party for a "No Board" report, which would start the countdown to a legal strike position.
- A federal response to Unifor's questions on the Roshel memorandum and Stellantis's Canadian commitments.
- Stellantis's decision on whether to proceed with the closure and sale of Brampton Assembly Plant.
- Clarity on production plans for Windsor Assembly and Etobicoke Casting under a new contract.
