Stellantis is expected to formally shut and sell its idled assembly plant in Brampton, Ontario, this weekend, eliminating roughly 3,000 jobs, according to Unifor, the union representing workers there. The automaker gave notice of the plan on Wednesday.

The plant has sat idle since early 2024, when Stellantis paused a retooling project intended to build next-generation Jeep models. Stellantis had previously committed to reopening the site.

The closure reflects mounting pressure on North American vehicle manufacturing from US tariffs on imported cars and parts. Stellantis has warned repeatedly that trade barriers have complicated production planning across its Canadian and Mexican operations. Chief Executive Antonio Filosa said the company is reviewing its global manufacturing footprint to protect margins.

Unifor National President Lana Payne condemned the move and called on the Canadian government to hold Stellantis to earlier investment pledges. Ontario Premier Doug Ford's office has previously pressed the automaker over provincial support tied to the retooling.

The closure marks one of the most significant blows to Canadian auto employment in years. Stellantis employs tens of thousands of workers across Ontario and has faced falling sales and profit declines in North America through 2026. Analysts at BMO Capital Markets have noted that tariff costs and weak demand have forced legacy automakers to consolidate underused capacity across the continent.
