Canada’s Unifor union and GM reach tentative deals

• Agreements cover workers at GM's Oshawa Assembly Plant, CAMI Assembly Plant in Ingersoll, and facilities in St. Catharines and Woodstock

• The tentative agreements follow Unifor's ratified deal with Ford that included 3% wage gains in each year of a three-year contract

Summary: Canada's Unifor Union and GM Reach Tentative Deals

Key Facts:

Canadian union Unifor announced Saturday it reached tentative labor agreements with General Motors (GM) affecting 4,600 union members across Ontario facilities.

Coverage and Locations:

The agreements encompass workers at four GM sites:

• Oshawa Assembly Plant
• CAMI Assembly Plant in Ingersoll
• Worksites in St. Catharines and Woodstock

Contract Details:

Unifor National President Lana Payne stated the agreements deliver "strong income and benefit gains," though specific percentage increases were not disclosed. The deals follow a pattern established earlier this month when Unifor ratified an agreement with Ford featuring 3% annual wage increases over a three-year contract period.

Timeline:

• Negotiations with GM began earlier in August 2026
• Ratification meetings scheduled for August 29-30, 2026
• Members will vote on whether to approve the tentative agreements

Market Implications:

The GM deal continues the trend set by the Ford agreement, suggesting consistency in labor cost increases across major automakers in Canada. The 3% annual wage increases at Ford likely served as a benchmark for GM negotiations. Pending member ratification, these agreements would provide labor stability for GM's Ontario operations through 2029, potentially affecting the company's North American production costs and competitiveness.

The successful negotiations may set expectations for future labor deals in Canada's automotive sector, with wage growth patterns now established across multiple manufacturers.
