Unifor and General Motors have reached a tentative collective agreement covering approximately 4,600 unionized employees at GM facilities across Ontario, marking a significant breakthrough in labour negotiations. The agreement, announced on Saturday, applies to workers at the Oshawa Assembly Plant, CAMI Assembly in Ingersoll, the St. Catharines Propulsion Plant, and the Woodstock Parts Distribution Centre. The deal must still be ratified by union members before it officially takes effect.
Negotiations between the two sides began on August 10 after Unifor successfully concluded bargaining with Ford Motor Company earlier this summer. Union leaders said the agreement follows the bargaining pattern established during the Ford negotiations and includes improvements in wages, employee benefits, and job security. However, the full details of the contract will remain confidential until union members have an opportunity to review and vote on the proposed agreement.
Unifor National President Lana Payne praised the bargaining committee for securing the tentative agreement during what she described as one of the most challenging periods facing Canada’s automotive industry. She said the proposed contract delivers meaningful gains in income and benefits while addressing the concerns of workers employed at GM’s Ontario operations. The union’s bargaining committee has unanimously recommended that members vote in favour of ratifying the agreement.
General Motors Canada also welcomed the tentative deal, describing it as an important step toward recognizing the contributions of its workforce while supporting the company’s long-term manufacturing operations in Canada. Company officials said additional information about the agreement will be released only after the ratification process is completed, in keeping with Unifor’s internal procedures.
The agreement comes at a crucial time for GM’s Canadian operations. About 30 per cent of the company’s unionized workforce had been on temporary layoff as negotiations began, with uncertainty surrounding production levels at several facilities. Labour analysts say a successful ratification would remove the immediate risk of labour disruptions and provide greater stability for Ontario’s automotive manufacturing sector.
Ratification meetings are expected to take place in the coming days, with union members deciding whether to approve the proposed contract. If accepted, the agreement will help secure labour stability at four major Ontario facilities and strengthen confidence in Canada’s automotive industry as it continues to navigate economic uncertainty and evolving market conditions.
