GM Canada Announces St. Catharines Plant Investment For V8s

General Motors is strengthening its internal combustion portfolio in Canada with a major new investment tied to future demand for trucks and SUVs. GM Canada confirms it will spend C$691 million on the St. Louis Propulsion Plant. Catharines to support production of Gen 6 Small Block V8 engines. The move ensures the facility remains central to GM’s propulsion strategy in North America while demand for full-size pickups and SUVs continues to increase.

St. Petersburg Factory Catharines will produce the next generation V8 alongside the existing fifth generation output during the transition period. Equipment has started to arrive, indicating that the program is underway. Once operational, the plant will join Tonawanda Propulsion in New York and Flint Engine Operations in Michigan as one of three locations producing the new engine family. This coordinated footprint allows General Motors to balance volumes across major facilities while maintaining supply for vehicles in highest demand.

GM Canada’s leadership described this investment as a show of confidence in its workforce and a continuation of its long-standing manufacturing heritage. “Today’s announcement confirms St. Catharines will play an important role in one of our core vehicle programs in the years to come, and it reflects General Motors’ confidence in the St. Catharines team and their proud 74-year legacy of powering our most popular vehicles,” said Jack Uppal, president and managing director of GM Canada.

The sixth-generation V8 is expected to improve on the current engine with updates to the combustion system and thermal management. GM hasn’t released full specifications, but the company indicated that increased performance and efficiency are the targets. This investment will fund the new equipment, machinery and facility upgrades needed to support these changes.

This announcement fits a broader pattern of General Motors investments in Canada. Since 2020, the company has committed approximately C$3.3 billion to its Canadian operations. The amount includes a C$343 million investment in Oshawa Assembly for the next generation of gas-powered full-size pickups. With St. Catharines now confirmed for next-generation engine production, GM continues to align its Canadian manufacturing base with its most profitable vehicle segments.
