11:59 pm ET on September 20 was the expiry Unifor’s September 11 statement put on the record, and it passed without a deal, an extension of the agreement or a strike notice. Formal talks have been paused since the September 11 impasse, when Stellantis offered the Detroit Three pattern on one condition, the closure of Brampton Assembly.
Conciliation is why the calendar did not produce a walkout. Unifor’s September 16 membership update said the union “will not be in a legal strike position as of September 20,” because conciliation under the Ontario Labour Relations Act “must be completed before Unifor or Stellantis can be in a legal strike / lockout position,” and that the next step for members, if the union goes there, is a strike vote. Ontario’s own collective bargaining guide sets the arithmetic: a legal strike or lockout may begin on the 17th day after the labour minister releases a no-board notice, and more than 50 per cent of those voting must vote to strike. The union says it is still assessing “the timing for setting a legal strike deadline, if that becomes necessary.”
2,200 Brampton members on indefinite layoff are the people the expiry touched first. Bargaining opened on September 1 for more than 9,000 workers at Stellantis Canada, about 2,200 of them laid off at Brampton since the plant built its last Charger, Challenger and 300 in December 2023. Those three nameplates sold 134,049 vehicles in the United States in 2023 and 7,715 in Canada, by GCBC’s count, within one unit per model of Stellantis’ own year-end table. The September 16 update extended the income-security provisions covering those members until the parties reach a legal strike or lockout position or a renewal agreement takes effect, whichever comes first.
Stellantis, in a letter to employees reported on September 21 by Buffalo Toronto Public Media, said market and trade conditions had “impacted the original business case for Brampton” and that no options had emerged to support a continued business case. The Roshel memorandum, the C$4.9 billion light utility vehicle contract Roshel’s plan depends on and has not won, and the default notice Ottawa served in December 2025 all stand where they stood on Friday.
Three things would count as news from here: a no-board notice, which starts the 17-day count; strike vote dates from the locals; or a tentative agreement inside conciliation, which would settle wages without answering whether selling Brampton satisfies the December notice. The surprise would be a definitive sale agreement before the industry minister answers Unifor’s five questions.
