Brampton Assembly built the Challenger SRT Demon. Today the plant’s own fact sheet doesn’t name a vehicle at all, an armoured-vehicle maker wants to buy it, and more than 9,000 Canadian Stellantis workers have given their union permission to walk out over it.
Unifor announced on Oct. 19 that 97.3% of members voting on Oct. 17 and 18 backed strike action if needed. That’s a big number, but it isn’t a strike yet. Under Ontario’s Labour Relations Act, a legal walkout requires more than a majority vote. A “no board” report also has to be issued, followed by a waiting period. The union says neither side has requested that report. So the vote is pressure, not a date on the calendar.
How talks broke down
The timeline is in Unifor’s own Sept. 11 statement. After 10 days of bargaining, the union declared an impasse and paused talks. According to Unifor, Stellantis had said in August that it was “seriously considering the closure and sale” of Brampton Assembly, and it had since signed a memorandum of understanding with Roshel, a defence supplier.

Unifor says Stellantis will match the pay pattern already settled at Ford and GM, on one condition: Brampton closes. Put plainly, Brampton’s workers would pay for everyone else’s raise. Unifor’s answer was that there will be no deal “without a suitable resolution for Local 1285 members at Brampton.” The contract expired Sept. 20 at 11:59 p.m.
Why Windsor matters just as much
The same statement flagged Windsor: Stellantis “has yet to confirm forecasted plans” for Windsor Assembly and the Etobicoke Casting Plant.
According to Stellantis’s Windsor fact sheet, that plant builds the Chrysler Pacifica, the Grand Caravan and Voyager, and the Dodge Charger Daytona. It’s a 4.4-million-square-foot building that produces both Stellantis’s minivans and the new Charger. A strike there would stop the Charger at the very moment Dodge is trying to persuade buyers that a muscle car without a Hemi can still sell.
Which is where the union’s real leverage sits. Stellantis wants out of Brampton, but it can’t easily lose Windsor.
A muscle-car factory with no cars to build
Stellantis’s Brampton fact sheet is short. The plant has 2.95 million square feet on 269 acres and is represented by Unifor Local 1285. It was built in 1986 and became Chrysler’s when it bought American Motors. The “Products” line no longer names a vehicle and just says the facility is undergoing retooling.
For a plant that once built Demons, that’s grim reading. In 2007, Chrysler spent $151 million so the reborn Challenger could share a line with the 300 and Charger. That flexible line went on to build some of the most outrageous production cars ever sold to the public, including the 2018 Challenger SRT Demon, which Stellantis’s own blog notes came off the line in Brampton.
The buyer is no stranger. Roshel already makes armoured vehicles in Brampton. In 2024, the city announced the company was investing more than $65 million in a new headquarters and production facility there.
Governments in the middle
On Oct. 21, Unifor welcomed a $2.5 billion federal-Ontario auto support package and used the moment to press its demands. It wants both governments to “stop the closure and sale of Brampton Assembly plant” and to attach enforceable production guarantees to public money.

Ottawa and Ontario just put $2.5 billion on the table, and Unifor wants every dollar tied to cars actually coming off a line. A buyer that builds armoured trucks may bring jobs, but it isn’t vehicle assembly, and the union argues that defence work can’t replace the supplier network a high-volume car plant supports.
What a strike would mean for owners and buyers
Most drivers won’t feel it for weeks. Dealers have stock, and parts for vehicles already on the road come from distribution networks, not the assembly line. If you want a new Pacifica or Charger in a specific configuration, a long shutdown means slower deliveries and less room to haggle.
There’s precedent for a short, sharp walkout. In the 2023 round, Unifor struck Stellantis’s Canadian plants briefly before reaching a tentative agreement. The difference now is that the main dispute isn’t about wages. It’s about whether a plant that once built Hellcats builds cars at all.
A 97.3% vote buys leverage, not a picket line. The date to watch is whenever someone files for a no-board report, because that starts the clock, and Windsor’s Charger line is where it would bite first. If you’re waiting on a Pacifica or a Charger, do you order now or sit tight until you see how this goes?
