The news: Unifor’s 9,000 Stellantis workers in Canada voted 97.3% to authorize a strike, and under Ontario law the earliest walkout would fall in November, around when Windsor Assembly comes back from a layoff.
Implications:
Restart: Windsor is idle through the week of Nov. 2 and due back the week of Nov. 9, the same stretch in which a strike could first become legal.
Cash timing: Automakers pay for parts a month and a half to two months after shipment, so a November stoppage would show up in supplier payments around the new year.
Built-ahead parts: Parts built for a restart can pile up if a strike follows, as at a Stellantis plant in 2023 that laid off workers once it “reached maximum inventory level.”
The News
Unifor members at Stellantis voted 97.3% in favor of a strike mandate in votes held Oct. 17 and 18. A strike would cover Windsor Assembly, which builds the Chrysler Pacifica minivan and the Dodge Charger, and the Etobicoke casting plant in Toronto.
Talks broke off Sept. 11 over Stellantis’ plan to close the idled Brampton plant and sell it to armoured vehicle maker Roshel, and the contract expired Sept. 20. Unifor says there will be no deal without a fix for its Brampton members, and it also wants production commitments for Windsor and Etobicoke.
“Strike action is always a last resort, but we will not back down,” said James Stewart, who chairs Unifor’s Stellantis bargaining committee. Stellantis said it “remains committed to bargaining in good faith.”
Why It Matters
Under Ontario law, a strike can’t begin until 16 days have passed after the province issues a “no board” notice, and Unifor says neither side has asked for one. Even if a notice came this week, the earliest walkout would fall in November, the same weeks Windsor restarts, so parts built and shipped for the restart could arrive at a line that stops again.
Zoom In
The November restart would be Windsor’s second this fall. The plant was idle the weeks of Sept. 21 and Sept. 28, came back Oct. 5, and is now on a three-week layoff covering the weeks of Oct. 19, Oct. 26 and Nov. 2. Windsor’s mayor said the feeder plants that supply the line have been down with it.
Dealers hold about 10,000 Pacificas, roughly three months of supply, so Stellantis has minivans to sell through a stoppage.
Last Time
In the 2023 US strikes, most suppliers held up at first because automakers pay for parts a month and a half to two months after shipment, so the cash from earlier work kept coming in. Even so, Ford said its strike alone led to more than 13,000 layoffs at nearly 90 supplier sites.
A stoppage that starts in November would show up in supplier payments around the new year.
Who’s Exposed
Windsor feeder plants: They have run on Windsor’s stop-start schedule since September, and a strike after the restart would extend the pause that began Oct. 19.
Etobicoke’s customers: The Toronto plant makes aluminum die castings for a range of Chrysler, Jeep, Dodge and Ram vehicles, so a strike there reaches beyond the minivan line.
US plants shipping north: US plants shipped $14.5 billion of vehicle parts to Canada in 2025 and bought $10.8 billion from it, according to Census trade data.
More parts cross into Canada from US plants than come back, so a stoppage in Ontario cuts orders on the US side too.

Week of Nov. 9: Windsor Assembly is due back from its layoff.
Once the province issues a no-board notice: the 16-day countdown to a legal strike starts. Unifor posts updates at autotalks.ca.
