Unifor began contract negotiations with Stellantis on September 1, 2026, in Toronto. This marks the final stage of the union's bargaining cycle with the Detroit Three automakers.

The Ford and General Motors benchmarks for 19,000 workers

Unifor is utilizing a strategy known as pattern bargaining to secure terms for its nealy 19,000 Canadian auto workers .. According to The Canadian Press, the union has already ratified collective agreements with Ford Motor Co. and General Motors this summer, which now serve as the baseline for the Stellantis talks.

By establishing these benchmarks, Unifor National President Lana Payne and the union leadership aim to ensure that wages, benefits, and job protections remain consistent across the Detroit Three. This approach typically streamlines negotiations, as the union seeks to replicate the successes of previous deals within the same bargaining round.

The fight to save the idled Brampton assembly plant

A primary point of contention in these talks is the future of the Brampton, Ontario, assembly plant. As reported by The Canadian Press , the facility has been idled since 2023, and Unifor recently received notice that Stellantis is considering selling or closing the site entirely.

The instability at the Brampton plant follows a shift in corporate strategy. While the facility was originally intended to be retooled for Jeep production, Stellantis paused those plans in early 2025 and subsequently moved the production of the Jeep Compass to the United States. This leaves the Ontario plant without a confirmed product, creating a precarious situation for the local workforce and the surrounding community.

Trump's threatened 50 per cent tariff hike on January 1

The negotiations are taking place against a backdrop of extreme trade volatility. Currently, a 25 per cent levy applies to all cars and trucks not built in the United States, though vehicles complying with the Canada-United States-Mexico Agreement are exempt. However, U.S. President Donald Trump recently threatened via social media to increase tariffs on all Canadian vehicles, auto parts, and steel to 50 per cent starting January 1.

These potential tariffs could fundamentally alter the leverage at the bargaining table. If the 50 per cent levy is implemented, the resulting cost pressures on Stellantis and other automakers may lead the company to push for concessions or accelerate the shift of production to the U.S. to avoid the tax . Unifor is consequently seeking stronger protections for Canadian jobs to insulate workers from these cross-border trade shocks.

What Stellantis is proposing for the Brampton workforce

Despite the urgency of the situation, several critical details remain obscured.. While Unifor has made its goals clear, the union leadership has not yet disclosed what specific proposals Stellantis has put forward regarding the Brampton plant's future in the new contract.

Furthermore, it remains unclear how Stellantis intends to balance the union's demand for "pattern" wages with the financial strain of the current 25 per cent U.S. tariffs. The report from The Canadian Press provides the union's perspective and the external trade threats, but it does not include a direct response or a counter-proposal from Stellantis management.
