Union members have been voting on whether to ratify the tentative agreements over the weekend.

Unifor National President Lana Payne previously said the agreements deliver strong wage and benefit increases for those working in GM’s Oshawa assembly plant, the CAMI facility in Ingersoll, as well as operations in St. Catharines and Woodstock.

Talks between the union and automaker started earlier this month after Unifor reached an agreement with Ford.

That agreement included three per cent annual pay increases and a renewal of a no-closure agreement.
