Key Facts
General Motors has reached a preliminary agreement with Unifor, the union representing roughly 4,600 GM employees across Ontario, involving a C$1.1 billion ($791 million) capital commitment spanning manufacturing sites in Oshawa, St. Catharines, and Ingersoll.
The allocation includes funding for production of the upcoming GMC Sierra heavy-duty truck at Oshawa and a next-generation transmission line scheduled to begin operations in late 2029.
U.S. tariffs on Canadian automotive products currently stand at 25%, with plans to raise them to 50% effective January 1, 2027.
GM shares opened Friday's session at $86.31, while Wall Street analysts maintain a consensus price target of $101.41 with a "Moderate Buy" rating.
The National Highway Traffic Safety Administration has opened an engineering review covering nearly one million GM trucks and SUVs over possible L87 V-8 engine failures.
Investment Breakdown
General Motors is committing C$1.1 billion to its Canadian manufacturing footprint following the preliminary labor contract with Unifor. The agreement covers three production facilities and comes amid escalating tariff pressure on Canada's automotive sector. Full-size pickups are among GM's highest-volume and most profitable product lines, making the location of heavy-duty truck assembly a significant production decision for the automaker.
The Oshawa manufacturing complex will receive C$144 million to support production of the next heavy-duty GMC Sierra pickup generation, part of GM's strategy to keep truck assembly operations in Canada.
A previously announced C$691 million pledge will fund production of advanced V8 powertrains across Ontario facilities. An additional C$215 million has been earmarked for GM's St. Catharines plant to build next-generation transmission systems, with operations projected to start in late 2029.
GM has also committed not to close or divest its CAMI assembly operation in Ingersoll while it evaluates alternative production strategies. The facility is considered a leading candidate if GM secures a Canadian Armed Forces defense manufacturing contract.
Unifor members will vote on the proposed agreement on Saturday and Sunday. The tentative deal follows Unifor's established pattern-bargaining approach, in which an agreement with one major automaker typically sets the template for negotiations with the others, meaning the terms reached with GM may shape upcoming talks across Canada's auto sector.
Tariff Backdrop
The investment arrives as Canadian automakers face 25% U.S. tariffs on finished vehicles. President Trump has announced plans to raise tariffs on Canadian automobiles, trucks, components, and steel to 50% beginning January 1, 2027.
Diplomatic negotiations between Washington and Ottawa collapsed last week without a resolution. Tariffs on medium- and heavy-duty vehicle categories remained among the contested issues. The Canadian and U.S. auto industries have long operated as a deeply integrated North American supply chain, with vehicles and components frequently crossing the border multiple times during production, which is why tariff levels on Canadian-built vehicles and parts carry weight for automakers' production and pricing decisions on both sides of the border.

An engineering analysis is a mid-stage step in NHTSA's defect investigation process, typically following a preliminary evaluation and, if warranted, preceding a potential safety recall determination.
