Unifor Sets a Stellantis Strike Vote for October 17-18

TLDR: Unifor said on October 6, 2026 that it will hold strike authorization votes at Stellantis Canada on October 17 and 18, with results announced October 19, because talks remain at an impasse over the Brampton Assembly Plant. A yes vote gives the bargaining committee the power to call a strike. Under Ontario law a legal strike can begin only on the 17th day after the labour minister releases a no-board notice, and none has been announced.

October 17 and 18 are the voting days in the union’s October 6 release, with the result due October 19. A strike authorization, the release says, “gives the bargaining committee the authority to call a strike if necessary” and “does not automatically mean a strike will take place.”

Ford and GM reached agreements with Unifor this round without a strike vote, and the union says it set out to do the same at Stellantis. What stopped it, in the release’s words, is an impasse over “the future of the Brampton Assembly Plant and the core economic pattern being conditional on an agreement to close and sell the plant.” The union adds that the open issues “extend well beyond” Brampton, to the job security of all members and the future of Stellantis Canada operations.

September 24 is the last time the union described the state of play. Its update to members said the parties were in mandatory conciliation under the Ontario Labour Relations Act, that Unifor was not in a legal strike position and that no strike votes had been scheduled. It also said the pattern terms for members at Windsor, Etobicoke, Mississauga and Red Deer stayed conditional on agreeing to close Brampton and sell it to Roshel, a defence contractor, the condition GCBC reported on September 15.

17 days after a no-board notice is the earliest a legal strike or lockout can begin under Ontario’s bargaining rules, whatever the vote says. The labour minister releases that notice when conciliation ends, and more than 50 per cent of those voting must back a strike for one to be legal. No notice has been announced. A notice released on October 19, the day the result is due, would make November 5 the first legal strike day.

2,200 or so laid-off Brampton members have the most riding on that count. Their income-security provisions were extended in September until a legal strike or lockout position or a new agreement, whichever comes first, as GCBC reported when the contract expired. A no-board notice would start the clock on that protection as well as on any walkout.

October 19 is the next date to check. Three things would count as news after it: a no-board notice, which starts the 17-day count; a return to formal talks; or a tentative agreement that sets wages without settling Brampton. A vote short of a majority would be the surprise.
