Unifor reached tentative agreements with General Motors (NYSE: GM) on Saturday covering more than 4,600 workers in Ontario. That is a bigger number than the union's last GM contract carried — but only because an idled fourth plant was folded into the master agreement this time.
Unifor is the union that bargains for autoworkers at the Detroit Three's Canadian plants. Its Saturday announcement covers four Ontario sites: Oshawa Assembly, the CAMI plant in Ingersoll, St. Catharines Propulsion and the Woodstock parts depot. The union's last GM contract covered only three of them. CAMI was not in that deal. It is in this one.
The arithmetic is where the headline count comes apart. The Associated Press reported that Unifor's October 2023 tentative agreement with GM covered about 4,300 workers at those same three sites. The union's own bargaining release of August 10, published the day talks opened, gave a plant-by-plant headcount for the unit now at the table:
- Oshawa Assembly (Local 222) — 2,750
- CAMI Assembly, Ingersoll, idled (Local 88) — 1,050
- St. Catharines Propulsion (Local 199) — 700
- Woodstock Parts Distribution Centre (Local 636) — 110
The three plants carried in the last contract now hold 3,560 people. They held about 4,300 then. The gap is about 740 jobs, a decline of roughly 17% in under three years.
CAMI covers that difference on paper and nothing at all in practice. Adding it lifts the headline above the last contract's total while adding no working shifts. So the unit did not grow. It absorbed a plant with no product to build, and the sites that do have product employ fewer people than they did at the last contract.
Why it matters
That is the backdrop worth holding while reading the headline count. Wage terms settle what GM pays each worker. They do not settle how many workers there are.
A labour agreement is usually read as a cost event. This one reads better as a disclosure about footprint. The union and the company have now agreed on what an hour of work is worth in Ontario. Neither has said how many of those hours GM intends to buy. For a manufacturer, that second question is the one that moves plants, suppliers and towns.
The pattern also sets the floor for the tables that follow. Whatever GM did or did not put in writing becomes the starting point for the next automaker, and then for the supplier contracts underneath it. So the thing to watch here is not the raise. It is what a shrinking bargaining unit says about where the work itself is going.
What is actually in the deal
On terms, Unifor's release is thin by design. GM Master Bargaining Chairperson Trevor Longpre said the committee "emerged with a deal that secures the pattern set by our union with Ford." National President Lana Payne said the agreements "deliver strong income and benefit gains, amid some of the most challenging times in our history." Details go to members at ratification meetings on August 29 and 30. The Globe and Mail reported on Saturday that the deal carries 3% annual pay increases and renews the no-closure agreement.
The Ford terms are public, and they are the template here. This is pattern bargaining: the union settles with one automaker, then presses the same package on the others. Unifor said its members at Ford ratified on July 19, with the master unit voting 74% in favour. That agreement covers 5,150 workers and, according to the union's July release, contains:
- 3% general wage increases in each of three years, plus renewed cost-of-living adjustments — automatic raises tied to inflation
- A top production rate of C$50.20 an hour by the end of the deal (US$36.48 at the Bank of Canada's August 21 daily rate of 0.7267 U.S. dollars per Canadian dollar)
- A top skilled-trades rate of C$62.71 (US$45.57 at the same rate)
- A C$10,000 (US$7,267) productivity and quality bonus and a C$2,000 (US$1,453) December bonus in the first year
- A term running from September 21, 2026 to September 19, 2029
Pattern bargaining works because the second and third companies have little room to argue. Ford set the shape, and GM's committee says it secured the same shape. What varies between companies is rarely the wage line. It is what each one puts on the table about plants and products.
The escalator itself has changed since the last round. The 2023 agreement paid 10% in the first year, then 2%, then 3%, according to Unifor's own summary of that contract.
Compounded, the old schedule lifted base rates about 15.6% over three years. Three straight 3% raises compound to about 9.3%. That is roughly 60% of the previous pace, before cost-of-living adjustments. Neither figure appears in either union release; both are arithmetic performed on the published schedules.
That is not a knock on the bargaining committee. The last round was negotiated into a post-pandemic price spike, and the large first-year number was catch-up for a stretch when inflation ran ahead of contracts. Inflation has since cooled, and the industry's problem has shifted from shortage to trade policy. A smaller escalator in that environment is what a pattern is supposed to produce.
What it costs GM
For GM, the wage bill here is small enough to be hard to see. Take the whole unit at the Ford pattern's top production rate for a full working year. That works out to roughly US$350 million of annual hourly wages. A 3% raise on that base is about US$10 million a year. The estimate is deliberately crude — it overstates the bill because Unifor said about 30% of the unit was on layoff when talks opened, and understates it because it excludes benefits, pension and payroll taxes.
Set that against the scale of the company. GM guided in July to full-year adjusted EBIT — operating profit before interest and tax, stripped of one-off items — of US$14 billion to US$16 billion. It guided separately to gross tariff costs of US$2.5 billion to US$3.5 billion. On those figures, the Canadian wage increase is under 0.1% of the low end of the EBIT range.
Which is precisely why the wage line is not the story. Investors watching this file are not watching the hourly rate. They are watching whether GM keeps building things in Ontario.
The commitment that is not in the release
On August 10, Longpre said members expected the Ford pattern respected and wanted the talks to "give certainty about the future of their facilities." On August 22, his quote covered the pattern and stopped there. Unifor's announcement names no product award and no plant investment. Jack Uppal, president and managing director of GM Canada, told The Globe and Mail the deal builds on GM's investments in Canadian manufacturing, and said more would follow after ratification.
The Ford settlement did name specifics. Unifor's July release credited that deal with $500 million for Windsor operations and $400 million for the Oakville Assembly Complex, both stated in U.S. dollars and tied to Super Duty production. The GM release announces wages and a unanimous committee endorsement. That is a real difference between two contracts the union itself calls the same pattern.
A pattern deal transfers money. It does not by itself transfer confidence. For workers at an idle plant, an hourly rate is theoretical until there is something to build. That gap — between what the agreement pays and what the union said it went in to get — is the part of this story the wage percentage does not carry.
CAMI is where the gap sits. Unifor said GM told it on October 21, 2025 that the company would stop building the BrightDrop electric delivery van there, ending the commercial van line GM had positioned as its fleet-EV business. The union said more than 1,000 of its members at the plant were on layoff at that point, and that GM had made no commitment about what comes next. The plant is now inside the master agreement and still has no announced replacement product.
The renewed no-closure agreement reported by The Globe and Mail is worth reading precisely. A commitment not to close a plant is not a commitment to run it. CAMI has spent most of the period since its idling in exactly that state — open on paper, silent in practice. The clause protects the address, not the shift schedule.
Oshawa is the same story with a product
GM cut a shift at Oshawa earlier this year, on February 2, ending about 500 direct jobs. Unifor put the supply-chain loss at more than 500 further positions. The company cited market conditions and the trade environment. The union said roughly 50,000 units of annual output shifted to Fort Wayne, Indiana, where GM was adding temporary workers.
Oshawa builds light- and heavy-duty Chevrolet Silverado pickups. Fort Wayne builds the GMC Sierra and the light-duty Silverado. So CAMI and Oshawa tell one story from opposite ends. CAMI lost work because a product did not sell. Oshawa lost work to a U.S. plant building the same truck, in a shift GM itself tied to market conditions and trade policy. A three-year wage schedule addresses neither cause. What it buys is quiet while those causes play out.
The previous round ended differently. The Associated Press reported that Unifor struck GM's Canadian plants early on October 10, 2023, and had a tentative agreement by that afternoon. That was a work stoppage measured in hours rather than days, and members ratified it. This time, The Globe and Mail reported that no strike occurred.
None of this makes the agreement a poor one for members. Holding a pattern at a company that has been shrinking its local footprint is itself a result. But the question a shareholder asks is not the question a member asks. The member asks what the rate is. The shareholder asks how many rates GM will still be paying in Ontario when this contract expires.
