The plant is still open. The Silverados it builds are still being assembled. The shift that employed those 500 people has simply ceased to exist. Meanwhile, GM has added 250 temporary jobs at its Fort Wayne, Indiana facility that also produces the Silverado. Canada is now pursuing millions in public funding it handed GM to keep exactly this from happening.
The Oshawa cuts did not arrive without warning. They came after years of public investment designed to anchor GM's Canadian operations as Trump's tariffs began to reshape the integrated North American auto supply chain. In 2022, the federal and Ontario governments committed up to CA$259 million each to GM's Oshawa plant and its CAMI facility in Ingersoll, a combined public contribution approaching CA$520 million. The expectation embedded in those commitments was production continuity and job security.
In October 2025, GM ended BrightDrop electric van production at the CAMI plant in Ingersoll, eliminating around 1,200 jobs. Three months later it cut Oshawa's third shift. Unifor, the union representing Canadian autoworkers, noted that GM had ramped up Silverado production in Fort Wayne before the Oshawa announcement. GM disputes that production was directly transferred.
Industry Minister Mélanie Joly did not soften her response.
"I had a meeting yesterday with people from GM and I told them that we would be getting our money back. If GM doesn't want to continue to invest more in Canada, we will invest more in other players. We'll fight for these workers and we'll find them jobs."
The clawback amount was described as running into the "millions," with the exact figure still being determined across both the Oshawa and Ingersoll commitments. The federal government confirmed it is also actively courting Hyundai, Volkswagen and Chinese manufacturers to replace the investment GM has pulled back.
Unifor National President Lana Payne was equally direct:
"General Motors has made a clear decision to cave to Donald Trump rather than stand up for its loyal Canadian workforce."
GM's position is that the shift reduction normalises post-pandemic production levels and that the company remains committed to Canada through a separate CA$280 million investment for next-generation full-size pickup production at Oshawa. The company has also noted it has invested more than CA$2.6 billion in Canadian manufacturing over the past five years.
For Stephen Hyde, a worker with decades at the plant, the corporate framing provided limited comfort.
"The unknown is really bad, because there's not a lot of jobs in Ontario. Right now, Ontario is not looking very good at all."

The wider picture
The Oshawa and Ingersoll cuts are not isolated events. They are the most visible indicators of a structural crisis that has been developing across Ontario's automotive sector since Trump's first term and has accelerated sharply since his return. Stellantis idled its Brampton Assembly Plant, which built the Chrysler 300 and Dodge Charger, leaving around 3,200 workers on indefinite layoff after a planned retooling was paused with no new model assigned and no restart date given. Combined with the GM cuts, Ontario has shed well over 5,000 automotive manufacturing jobs in the past twelve months.
Canada's auto sector is particularly vulnerable to US tariff pressure because of how deeply integrated it is with American supply chains under the legacy of the original Auto Pact and its successor CUSMA arrangements. A Silverado built in Oshawa contains components that cross the US-Canada border multiple times during assembly. A 25 per cent tariff on auto imports does not just affect finished vehicles. It adds cost to every border crossing those components make, and the vehicle that emerges from the end of the line arrives in the American market at a price disadvantage against the identical model built in Fort Wayne.
Toyota's recent launch of the new RAV4 at its Cambridge, Ontario plant, which Joly pointedly contrasted with the GM cuts, and Honda's decision to pause EV supply chain investment without reducing its workforce, suggest the problem is not Canadian manufacturing competitiveness per se. It is specifically the choices being made by companies with the option to relocate production south of the border.
Carney's government has responded on two fronts simultaneously. Domestically, it is pursuing the subsidy clawbacks and ramping up support for affected workers, while signalling to new entrants that Canada has facilities, a workforce and minerals supply they need. Internationally, Carney signed a deal with Chinese President Xi Jinping allowing 49,000 Chinese EVs into Canada annually at a reduced tariff rate in exchange for the rolling back of Chinese tariffs on Canadian canola and other agricultural exports. The move is designed to diversify Canada's auto market relationships away from exclusive dependence on American-connected supply chains. It has generated sharp criticism domestically, including from Ontario Premier Doug Ford, whose own government accepted the same subsidy frameworks that are now being used as leverage against GM.
The Oshawa plant is still running. The CA$280 million next-generation truck investment is still on the books. Oshawa's autoworkers, in the words of Unifor Local 222 President Jill Gray, will outlast Trump. Whether GM's remaining Canadian operations outlast the current tariff environment, and whether the clawback mechanism actually recovers meaningful public funds, are the questions the next twelve months will answer.
