Unifor, GM Reach Tentative Deal for 4,600 Ontario Autoworkers

TORONTO — Canada's largest private-sector union has reached a tentative agreement with General Motors, covering roughly 4,600 autoworkers across four Ontario facilities, just as a new wave of punishing U.S. tariffs takes effect at the border. The deal, announced Saturday morning by Unifor, comes after negotiations that began Aug. 10 and concluded one day past the union's self-imposed Aug. 21 target deadline.

Unifor national president Lana Payne said the bargaining committee worked "diligently to reach these agreements, which deliver strong income and benefit gains, amid some of the most challenging times in our history." The tentative agreement covers workers at GM's assembly plant in Oshawa, the CAMI assembly plant in Ingersoll, the Propulsion plant in St. Catharines, and the Parts Distribution Centre in Woodstock.

The deal still requires ratification by union members, though Unifor's bargaining committee said it is unanimously endorsing the agreement. Terms of the deal were not immediately available as of Saturday afternoon, but the union has signalled it expects the agreement to follow the pattern established in its recent contract with Ford Motor Company.

What's at Stake: Four Plants, Thousands of Jobs

The tentative agreement touches communities across southern Ontario that have long depended on the auto sector for stable, well-paying manufacturing work. Unifor represents 2,750 members at the GM plant in Oshawa, 1,050 at the idled CAMI plant in Ingersoll, 700 at the St. Catharines Propulsion plant, and 110 at the Parts Distribution Centre in Woodstock — roughly 4,610 workers in total.

As talks opened in early August, approximately 30 per cent of Unifor members at GM in Canada were on layoff, a figure that underscores the fragility of the current moment for the industry. Trevor Longpre, chairperson of the Unifor General Motors Master Bargaining Committee, said members expect the Ford pattern to be respected and want "certainty about the future of their facilities."

The Oshawa plant, once slated for closure, has been revitalised in recent years and now builds pickup trucks for the North American market. The St. Catharines facility produces engines and other propulsion components. The Woodstock parts centre serves as a key logistics hub for GM's Canadian operations. Each facility represents not just jobs, but the economic anchor of its surrounding community.

The Ford Pattern: A Template for These Talks

Unifor's approach to bargaining with the Detroit Three has long relied on pattern bargaining — negotiating a template agreement with one automaker, then pressing the others to match it. This year, Ford was the pattern-setter. In July, Unifor members ratified a new three-year contract with Ford by a 74 per cent margin, covering roughly 5,100 to 5,600 hourly workers.

The Ford deal included three per cent annual pay increases — about nine per cent over the life of the contract — and brings full-rate production workers' wages to approximately $50.20 per hour by the final year. It also includes a renewal of a no-closure agreement and program commitments at all Ford facilities, including a third shift at its engine plant in Essex, Ont., forecast for 2029.

Ford committed roughly US$500-million at the Essex engine factory and US$400-million at the Oakville pickup assembly plant — about $1.25 billion in planned investment across its Canadian operations. The contract takes effect Sept. 21.

When negotiations with GM opened Aug. 10, Payne said the union was "entering this next round of negotiations with the solid foundation established by the pattern agreement with Ford." Jack Uppal, president and managing director of GM Canada, said the company was entering talks with "profound respect for the collective bargaining process."

The CAMI Ingersoll Problem: An Idled Plant at the Centre of Talks

The most pressing issue in these negotiations is the CAMI assembly plant in Ingersoll, which currently sits idle with workers laid off. The plant had been building BrightDrop electric commercial delivery vans, but GM ended that production amid lower-than-expected EV demand and rising costs from regulatory changes and imports.

The CAMI plant employs approximately 1,200 workers and has faced retooling disruptions, rotating layoffs, and extended idling. Unifor Local 88 CAMI plant chair Mike Van Boekel has described the slowdown as "devastating" for the community. Ingersoll, a town of roughly 12,000 people in southwestern Ontario, has felt the economic ripple effects acutely.

The future of CAMI is likely to be a central issue in the ratification vote. Workers there will want to know whether the tentative agreement includes commitments to restart production, retool the facility for new products, or provide meaningful income support during any continued downtime. The union has not yet released the specific terms regarding CAMI's future.

A Brutal Backdrop: 50 Per Cent Tariffs Take Effect

The tentative agreement lands on the same day that 50 per cent U.S. tariffs on billions of dollars of Canadian goods took effect, after Canada-U.S. trade talks collapsed Friday night. Prime Minister Mark Carney said Canada was "walking away from a bad deal" and recalled the negotiating team to Ottawa. Canada has vowed a dollar-for-dollar response and suspended trade talks with Washington.

U.S. President Donald Trump had delayed the 50 per cent tariffs by three days, citing progress in trade talks and claiming "we have a deal" with Canada. That claim proved premature. The auto sector has been repeatedly targeted by U.S. tariffs since 2025, creating immense uncertainty for Canadian manufacturers and workers alike.

The tariff backdrop is not abstract for the workers covered by this tentative agreement. Stellantis's Windsor Assembly Plant and Brampton Assembly Plant have faced temporary closures and pauses amid the tariff turmoil. GM's Canadian operations have not been immune to the broader instability, even before this latest escalation.

For Unifor, negotiating a contract that delivers wage gains and job security while the industry faces an unpredictable trade environment is a delicate balancing act. The union's leadership has been clear that the Ford pattern must be respected, but the economic realities of tariffs, shifting consumer demand, and the transition to electric vehicles complicate matters.

What Happens Next: Ratification and the Road Ahead

The tentative agreement now moves to ratification votes by Unifor members at the four GM facilities. The union's bargaining committee has unanimously endorsed the deal, which is a strong signal to members, but ratification is never a foregone conclusion. Workers will scrutinise the terms carefully, particularly those at CAMI who have borne the brunt of layoffs and uncertainty.

If ratified, the contract will take effect following the same timeline as the Ford agreement, with the pattern deal's terms serving as the baseline. The three per cent annual raises and the top production wage of approximately $50.20 per hour would apply to GM workers as well, assuming the pattern holds.

Beyond ratification, the bigger question is what happens next for GM's Canadian operations. The company has pointed to its investment record — $3.3 billion in Canadian manufacturing plants since 2020 — as evidence of its commitment. Uppal said the goal is "to reach a mutually beneficial agreement that supports our employees while keeping GM Canada competitive for the long term."

But the tariff situation remains unresolved, and the federal government's response is still taking shape. Carney's decision to walk away from trade talks and recall negotiators to Ottawa signals a harder line, but the consequences for the auto sector could be severe if the tariffs persist.

For the 4,600 workers covered by this tentative agreement, the immediate priority is ratification. The longer-term challenge — securing the future of their plants in an era of tariffs, electrification, and shifting global supply chains — will require sustained attention from the union, the company, and governments at all levels.

The tentative agreement is a significant milestone, but it is not the finish line. It is a foundation upon which the next three years of labour relations at GM Canada will be built. Whether that foundation holds will depend on the votes of the workers themselves, and on the broader economic forces that none of the parties fully control.
