Unifor and General Motors reached tentative collective agreements covering approximately 4,600 unionized autoworkers across Ontario following 12 days of negotiations. The deals, which secure pattern-setting terms established earlier with Ford Motor Co., address income gains, benefit improvements, and job security amid ongoing tariff uncertainty.
The Bottom Line
- Scope of Impact: The tentative agreements apply to roughly 4,600 workers across the Oshawa Assembly Plant, St. Catharines Propulsion Plant, Woodstock Parts Distribution Centre, and the idled CAMI Assembly Plant in Ingersoll, Ontario.
- Pattern Bargaining: Unifor successfully locked in the wage and benefit framework previously negotiated with Ford Motor Co. on July 11.
- Ratification Timeline: Union members will review details during upcoming ratification meetings scheduled for August 29 and 30, following the expiration of current contracts in September.
Navigating Tariff Pressures and Production Realities
The negotiations concluded under considerable macroeconomic strain. According to Unifor GM Master Bargaining Chairperson Trevor Longpre, negotiators entered the room facing “tariff uncertainty and relentless U.S. trade aggression.” Despite these headwinds, the bargaining committee secured unanimous endorsement for agreements designed to stabilize Canadian manufacturing output.
For General Motors, maintaining labor stability in Ontario is critical to protecting regional supply chains. GM Canada President and Managing Director Jack Uppal noted that the agreements appropriately recognize employee contributions while building on the automaker’s ongoing capital investments in Canadian manufacturing.
The CAMI Assembly Factor and Past Adjustments
A central point of discussion during this bargaining cycle involved the operational status of the CAMI Assembly Plant in Ingersoll, Ontario. Located roughly 140 miles from Detroit, the facility has operated on a separate contract negotiation cadence stemming from its time as a joint venture with Japanese automaker Suzuki.
Production adjustments at CAMI remain a fresh memory for the workforce. In October 2025, GM scaled back production of the electric Chevrolet BrightDrop van due to low demand. That shift resulted in layoffs affecting approximately 1,000 employees—leaving staffing levels at less than half of what the plant employed just over three years prior when it manufactured gas-powered Chevrolet Equinox models. Since its closure, GM Canada has said that CAMI continues to be assessed for future opportunities.
| Facility Location | Operational Focus | Bargaining Status |
|---|---|---|
| Oshawa Assembly Plant | Vehicle Assembly | Tentative Agreement Reached |
| St. Catharines Propulsion Plant | Powertrains and Components | Tentative Agreement Reached |
| Woodstock Parts Distribution Centre | Logistics and Parts | Tentative Agreement Reached |
| CAMI Assembly Plant (Ingersoll) | Electric Commercial Vehicles (BrightDrop) | Separate Contract, Tentative Agreement Reached |
Broader Market Implications and Next Steps
Unifor, Canada’s largest union in the private sector representing 320,000 workers, has now secured two major pattern agreements.
As union members prepare to cast their votes on August 29 and 30, the ultimate test of these agreements will lie in execution.
