GM next-generation V8 engine production confirmed for Canada as ICE strategy continues

On January 30, 2026, GM confirmed that its GM next-generation V8 engine will be manufactured at the St. Catharines Propulsion facility in Ontario, Canada, underscoring the company’s continued focus on internal combustion engine programs. The announcement came as GM Canada shared multiple updates related to its manufacturing footprint and propulsion investments.

GM Canada manufacturing footprint and propulsion strategy

The decision to localize the GM next-generation V8 engine in Canada reflects long-term planning around propulsion systems. GM Canada highlighted ongoing investments aimed at maintaining operational strength across its Canadian facilities while supporting future powertrain requirements. The St. Catharines Propulsion plant already plays a critical role in GM’s engine supply chain. It currently produces Gen 5 V8 engines, including the 5.3L L84 and 6.2L L87 units, making it a logical base for transitioning to the next generation of V8 technology.

Oshawa Assembly updates and workforce adjustments

GM also confirmed changes at Oshawa Assembly as part of the broader operational realignment. The plant is scheduled to return to two shifts starting February 2, a move that will result in more than 500 employees being placed on layoff.

Role of Oshawa in GM’s truck strategy

Despite the workforce impact, GM emphasized that Oshawa Assembly remains a cornerstone of its full-size truck production strategy. Preparations are ongoing to support future ICE-powered pickups, backed by a CAD 280 million investment focused on tooling, flexibility, and manufacturing readiness. Oshawa holds a unique position within GM’s North American network, as it is the only facility producing both light-duty and heavy-duty Chevrolet Silverado models on a single assembly line.

Next-generation pickups and V8 engine roadmap

General Motors is preparing to introduce the 2027 Chevrolet Silverado 1500 and 2027 GMC Sierra 1500, both expected to feature the new Gen 6 Small Block V8 engine. This GM next-generation V8 engine is anticipated to be offered in multiple displacements, including 5.7 liters and 6.7 liters. The Gen 6 V8 lineup is expected to replace the current Gen 5 V8 engines, aligning updated combustion technology with GM’s evolving performance, efficiency, and regulatory requirements. By anchoring production in Canada, GM reinforces its confidence in ICE demand for full-size trucks well into the next decade.
