What's really happening at GM plants in Canada
General Motors currently operates a small but strategically focused manufacturing footprint in Canada, centered on three core facilities: the **Oshawa Assembly** plant in Ontario, the **CAMI Assembly** plant in Ingersoll, Ontario, and the **St. Catharines Propulsion** plant in St. Catharines, Ontario. These **GM manufacturing plants in Canada** collectively anchor the company's North American supply chain for both internal-combustion and next-generation electric propulsion systems, while also housing a growing cluster of software and engineering operations.Current GM manufacturing footprint in Canada
As of 2026, GM maintains three principal manufacturing facilities in Canada, down from a larger network in previous decades. The **Oshawa Assembly** plant in Oshawa, Ontario, is the only active vehicle assembly plant for GM in the country and produces the **Chevrolet Silverado** light-duty and heavy-duty trucks. The **CAMI Assembly** facility in Ingersoll, Ontario, has transitioned from conventional vehicle production to become Canada's first full-scale commercial electric-vehicle manufacturing hub, having assembled the BrightDrop Zevo 600 electric van through roughly 2025. Nearby, the **St. Catharines Propulsion** plant manufactures gasoline engines and is being retooled to produce Ultium electric-drive motors, reflecting GM's broader pivot toward electrification.
These three facilities form the backbone of GM's **Canadian manufacturing footprint**, representing a mix of vehicle assembly, propulsion, and future-facing EV technology. Each site is embedded in Ontario's established automotive corridor, taking advantage of regional supplier networks and a highly skilled workforce. Together they account for the majority of GM's localized production and investment in Canada, even as the company consolidates certain product lines and shifts volumes to other North American plants.
Key operating GM plants and their roles
- Oshawa Assembly in Oshawa, Ontario: Produces the Chevrolet Silverado light-duty and heavy-duty trucks and is GM's only vehicle assembly plant currently operating in Canada. The facility has been heavily modernized since 2020, with more than C$1.5 billion invested in tooling, stamping, and assembly lines to support the latest generation of full-size trucks.
- CAMI Assembly in Ingersoll, Ontario: Converted into Canada's first full-scale commercial EV manufacturing hub, CAMI built the BrightDrop Zevo 600 electric delivery van before shifting production out of Canada in 2025. The plant remains a key test bed for flexible EV manufacturing within GM's broader North American strategy.
- St. Catharines Propulsion in St. Catharines, Ontario: Manufactures V-8 and V-6 engines today but is being transformed into a hybrid propulsion facility that will also produce Ultium electric drive motors. GM has committed roughly C$691 million there in 2026 to support the next generation of GM V-8 engines while preparing the plant for a longer-term EV-focused mission.
These three plants illustrate how GM is balancing legacy demand for internal-combustion powertrains with the structural shift toward electrification. The **Oshawa Assembly** site, for example, continues to focus on full-size pickups, which remain a core profit center for GM across North America. Meanwhile, **CAMI Assembly** and **St. Catharines Propulsion** are being repositioned around battery-electric drivetrains, even as some existing vehicle programs are phased out or moved to other regions.
Recent investments and production shifts
GM has plowed more than C$2 billion into its Canadian operations since 2020, with the lion's share directed at the **Oshawa Assembly** and **St. Catharines Propulsion** plants. In February 2026, GM announced a C$63 million investment to upgrade stamping operations at the Oshawa facility, extending its role as the sole Canadian truck assembly site despite the recent elimination of a third shift and associated workforce reductions. The company has also committed C$280 million in earlier funding to support next-generation internal-combustion full-size trucks, reinforcing Oshawa's strategic importance.
At **St. Catharines Propulsion**, the C$691 million investment in 2026 targets the sixth generation of GM's V-8 engine platform while simultaneously preparing the plant for high-volume Ultium drive-motor production. GM executives estimate that the facility will eventually manufacture about 400,000 electric motors per year as part of the company's broader goal of producing 20 million EVs globally by the late 2020s. This dual-track strategy lets GM meet continuing demand for **full-size trucks and SUVs** in Canada and the U.S. while laying the groundwork for a largely electric propulsion portfolio.
Workforce and community impact
Each of these **GM manufacturing plants in Canada** supports thousands of direct and indirect jobs, making them critical anchors for regional economies in Ontario. The Oshawa complex, including assembly and ancillary operations such as stamping and sub-assembly, is estimated to support roughly 2,500-3,000 direct employees, with many more working at supplier parks and logistics hubs nearby. CAMI Assembly in Ingersoll has historically supported several hundred line-production workers, although those numbers have fluctuated as production of the Zevo 600 was phased out.
GM has also expanded its **engineering and software footprint** in Canada, committing to hire up to 1,000 software engineers focused on connected, autonomous, and electrified vehicle technologies. Many of these roles are centered in Ontario, with major hubs in **Oshawa, Markham, and Waterloo**, reinforcing the idea that Canadian operations are not just about metal-bending but also about digital innovation. The company has likewise invested in cold-weather testing and advanced technology infrastructure at sites such as the **Kapuskasing Proving Ground**, which underpins reliability testing for vehicles sold across Canada and the northern U.S.
Illustrative GM Canada plant overview (2026)
The table below summarizes the main active GM manufacturing plants in Canada, their current product focus, and approximate investment levels since 2020. Data are rounded for readability and educational illustration rather than as audited financial figures.
| Plant | Location | Primary Output (2026) | Recent Investment (C$) | Workforce Estimate |
|---|---|---|---|---|
| Oshawa Assembly | Oshawa, Ontario | Chevrolet Silverado LD & HD | ~C$1.5 billion (2020-2026) | ~2,700 direct |
| CAMI Assembly | Ingersoll, Ontario | BrightDrop Zevo 600 (EV van, pre-2025) | ~C$1.0 billion (2020-2025) | ~450-600 during peak EV production |
| St. Catharines Propulsion | St. Catharines, Ontario | V-8/V-6 engines + Ultium drive motors | ~C$691 million (announced 2026) | ~1,200 direct |
This structure makes clear that GM's **Canadian manufacturing** strategy is concentrated, capital-intensive, and heavily oriented toward high-margin trucks and flexible propulsion systems. The Oshawa, CAMI, and St. Catharines plants also serve as integration nodes for supplier networks, logistics, and R&D capacity across southern Ontario.
Future trajectory and electrification plans
GM's long-term roadmap for Canada hinges on reshaping the **St. Catharines Propulsion** and **CAMI Assembly** sites as electrification-centric facilities, even as the **Oshawa Assembly** plant continues to focus on internal-combustion full-size trucks for the foreseeable future. Company statements indicate that Ultium drive-motor output at St. Catharines will gradually increase between 2026 and the end of the decade, with the intent that EV propulsion will eventually "squeeze out" legacy V-8 and V-6 engine production. That transition is expected to coincide with broader GM targets of producing millions of EVs across North America by 2030.
While CAMI's current electric-van program has been shifted out of Canada, GM executives have emphasized that the Ingersoll plant remains an option for future EV or flexible-platform projects if market conditions and product strategies shift. That flexibility is part of a larger "flexible manufacturing" narrative GM is using to justify keeping its Canadian footprint lean yet highly adaptable. Over the next five years, stakeholders in Canada can expect additional announcements tied to battery-adjacent technologies, software development, and testing infrastructure, even if the overall number of assembly plants does not materially increase.
How GM Canada fits into the broader North American strategy
GM's **Canadian manufacturing plants** represent a relatively small share of the company's global factory count but play an outsized role in North American full-size truck and propulsion supply. The Oshawa Assembly plant, for example, is the only facility in Canada building GM's flagship pickups, which dominate domestic sales and export patterns into the U.S. and other markets. St. Catharines Propulsion similarly feeds engine and motor lines that supply multiple North American assembly plants, effectively turning the Canadian site into a regional propulsion hub.
Policy and trade dynamics also shape GM's calculations in Canada. The company must navigate supply-chain rules under the **USMCA trade agreement**, regional incentives for clean-energy manufacturing, and federal and provincial climate targets that favor electrification. These factors help explain why recent investments are tilted toward hybrid-capable propulsion at St. Catharines and toward flexible, modernized stamping and assembly at Oshawa rather than a broad expansion of green-field plants. As a result, GM is using its existing **Canadian manufacturing footprint** to straddle the ICE-to-EV transition, rather than betting on a wholesale plant-building spree.
Supply chain and parts-distribution infrastructure
Beyond the three core plants, GM operates a network of **parts-distribution centers** and logistics nodes across Canada that are essential to the functioning of its Canadian operations. These include major facilities in Langley, British Columbia; Edmonton, Alberta; Woodstock, Ontario; and Point-Claire, Quebec, which handle service parts, aftermarket components, and materials for manufacturing plants. The integration of these distribution centers with the **Oshawa Assembly** and **St. Catharines Propulsion** plants helps minimize inventory costs and supports just-in-time manufacturing practices.
GM has also integrated its Canadian operations into broader North American logistics corridors, linking **Ontario plants** with major U.S. assembly and battery sites. This cross-border integration is critical for transporting components such as Ultium drive motors, engine blocks, and assembled trucks across the Great Lakes region. As GM scales up EV production, the company will likely invest further in digital supply-chain tools and regional warehousing around these Canadian hubs to manage the added complexity of battery-pack and electric-motor logistics.
Environmental and industrial policy context
GM's strategy for **Canadian manufacturing plants** is shaped heavily by Canada's evolving industrial and climate policies, including federal and provincial programs aimed at decarbonizing the transportation sector. The Canadian government has paired incentives for zero-emission vehicles with support for clean-technology manufacturing, which aligns with GM's plans to expand Ultium drive-motor output at **St. Catharines Propulsion**. Meanwhile, Ontario's focus on maintaining its position as North America's vehicle manufacturing heartland has led to tailored support for projects like the Oshawa truck-assembly upgrades.
Independent analysts estimate that the Canadian automotive sector accounts for roughly 10-12% of national manufacturing GDP, underscoring why **GM's Canadian operations** are closely watched by policymakers. As GM shifts more of its Canadian capacity toward electric propulsion and software-driven vehicles, the company is positioning itself to benefit from both federal climate-aligned incentives and provincial job-retention strategies. That policy environment helps explain why GM continues to invest heavily in existing plants rather than shuttering the Canadian footprint entirely.
Summary of major current GM plants in Canada
As of 2026, GM's active manufacturing presence in Canada is anchored by three principal sites: the **Oshawa Assembly** plant, the **CAMI Assembly** plant, and the **St. Catharines Propulsion** plant. Oshawa remains the sole Canadian vehicle assembly location, producing the Chevrolet Silverado light-duty and heavy-duty trucks with more than C$1.5 billion invested between 2020 and 2026. CAMI Assembly transitioned to be Canada's first full-scale commercial EV manufacturing hub, having built the BrightDrop Zevo 600 until production was phased out in 2025.
The **St. Catharines Propulsion** plant illustrates GM's hybrid strategy, currently producing gasoline V-8 and V-6 engines while also ramping up Ultium electric drive-motor output. With a planned C$691 million investment in 2026, St. Catharines is expected to eventually become a largely electric-propulsion facility, feeding multiple GM EV platforms. Together these three plants encapsulate what is really happening at GM plants in Canada: a leaner, capital-intensive, and electrification-oriented footprint that remains tightly integrated with North American demand for trucks and high-performance vehicles.
Key concerns and solutions for Gm Plants In Canada Are Busier Than You Think
Are there any other GM plants besides Oshawa, CAMI, and St. Catharines in Canada?
As of 2026, GM's primary manufacturing activity in Canada is concentrated in the three main plants: the **Oshawa Assembly** plant in Oshawa, Ontario; the **CAMI Assembly** plant in Ingersoll, Ontario; and the **St. Catharines Propulsion** plant in St. Catharines, Ontario. While GM maintains administrative offices, engineering centers, and proving grounds across Canada-such as its Canadian headquarters in Oshawa and facilities in Markham and Kapuskasing-these are not classified as vehicle manufacturing plants. The company's public Canadian operations profile lists only those three manufacturing facilities as its core industrial sites.
What vehicles are currently built in Canada?
The only vehicles currently assembled in Canada at a GM plant are the **Chevrolet Silverado** light-duty and heavy-duty pickups, which are produced at the **Oshawa Assembly** plant. In recent years, the **CAMI Assembly** facility in Ingersoll assembled the BrightDrop Zevo 600 electric delivery van, but that program has been shifted out of Canada and production there is no longer active as of 2026. All other GM vehicles sold in Canada are imported from various U.S. and Mexican plants, underscoring the relatively narrow but high-value focus of GM's current Canadian manufacturing portfolio.
Is GM planning to build more electric vehicles in Canada?
GM has not yet announced another EV assembly program to replace the BrightDrop Zevo 600 at **CAMI Assembly**, but the company is actively positioning its Canadian plants to play a larger role in electrification. The **St. Catharines Propulsion** plant is already being retooled to produce Ultium electric drive motors, with executives indicating that EV propulsion will eventually dominate the site's output over legacy gasoline engines. GM Canada leadership has also stated that it sees Canada as a potential hub for future EV or flexible-platform projects, meaning that additional announcements about electric-vehicle production in Canada are possible if market and policy conditions evolve.
How many people do GM plants in Canada employ?
Exact employment figures change over time, but GM's Canadian operations are estimated to support several thousand direct manufacturing jobs across the **Oshawa Assembly**, **CAMI Assembly**, and **St. Catharines Propulsion** plants. The Oshawa complex alone is often cited in the range of roughly 2,500-3,000 direct employees, when including assembly and related operations such as stamping and sub-assembly. St. Catharines Propulsion supports on the order of about 1,200 direct positions, while CAMI's workforce has fluctuated depending on the specific production program, peaking around 450-600 workers during the BrightDrop Zevo 600 run.
Why did GM cut a shift at the Oshawa plant?
In January 2026, GM eliminated the third shift at the **Oshawa Assembly** plant, a move that resulted in around 500 direct layoffs and affected additional jobs at supplier companies tied to that shift. The decision followed a broader reassessment of demand for full-size trucks and a desire to align production schedules with actual North American sales volumes, rather than maintaining excess capacity. At the same time, GM emphasized that it would continue to invest in the plant-announcing a C$63 million stamping upgrade later that year-signaling that Oshawa remains strategically important despite the shift reduction.
What is the timeline for electrification at St. Catharines?
GM expects the **St. Catharines Propulsion** plant to operate as a hybrid facility for several years, producing both gasoline V-8 and V-6 engines and Ultium electric drive motors in parallel. Company statements indicate that EV motor output will gradually increase through the late 2020s, with the long-term goal of transitioning the plant into a predominantly Ultium-focused propulsion site. The C$691 million investment announced in 2026 is designed to support the sixth-generation V-8 engine through much of the decade while also enabling the ramp-up of electric-drive production, effectively stretching the crossover window between internal-combustion legacy and EV future.
How will GM's Canadian plants affect the local economy?
Each of the three main **GM manufacturing plants in Canada** supports a dense network of suppliers, logistics providers, and service businesses, meaning that every direct job at Oshawa, CAMI, or St. Catharines typically translates into several additional indirect jobs in the region. Municipal and provincial governments in Ontario have long treated GM's presence as a cornerstone of their industrial policy, given the importance of **automotive manufacturing** to regional GDP and employment. As GM shifts more of its Canadian operations toward electrification and software-driven vehicles, local economies are likely to see a mix of legacy ICE-related activity and new high-skilled roles in advanced manufacturing and engineering.
Are any GM plants in Canada at risk of closure?
GM has not announced plans to permanently close any of its current **Canadian manufacturing plants** as of 2026, even though the company has scaled back certain product lines and shifts. The elimination of the Zevo 600 program at **CAMI Assembly** and the loss of a third shift at **Oshawa Assembly** have reduced activity at those sites, but both plants remain active within GM's broader North American network. Executives have repeatedly emphasized that their substantial investments in Oshawa and St. Catharines-totaling billions of dollars since 2020-signal a long-term commitment to Canadian manufacturing, even as the portfolio evolves toward electric propulsion.
