General Motors secures three-year Canada labor deal, pledges over C$1 billion investment

General Motors' Canadian workforce ratified two new three-year labor agreements with Unifor on August 30, 2026, following a tentative deal reached August 22. Members at the automaker's Oshawa, St. Catharines, and Woodstock plants (the GMCC agreement) voted 80.5% in favor, while workers at the separate CAMI assembly plant in Ingersoll ratified their own contract by a wider 96.5% margin.

The dual ratifications land as GM works to secure a stable Canadian manufacturing base amid ongoing US tariff pressure on the auto sector. Locking in labor peace for three years reduces the near-term risk of a work stoppage and gives the automaker a clearer path to plan capital spending in Ontario.

Alongside the new contracts, GM confirmed plans to invest C$1.1 billion (US$791 million) across its Canadian operations. The spending is allocated by plant: C$144 million for next-generation heavy-duty GMC Sierra production at Oshawa, C$215 million for next-generation transmission assembly in St. Catharines, C$691 million for sixth-generation V8 engine production also in St. Catharines, and C$63 million for stamping and CCA upgrades at Oshawa. The agreements also raise wages 3% annually for three years, lifting full-rate pay to $50.20 an hour and skilled trades pay to $62.71 an hour, renew a cost-of-living allowance, and add a $10,000 productivity bonus plus a $2,000 December bonus for eligible members.

Analysts will watch how GM phases the plant-by-plant spending, particularly the St. Catharines transmission line targeted for late 2029, and whether the deals translate into steadier production through the contract term. The ratified agreements reduce strike risk for now, offering a clearer near-term outlook for investors and suppliers tied to GM's Ontario operations.
