The Globe and Mail reports in its Thursday edition that the ripple effects from the strike at the General Motors assembly plant in Ingersoll, Ont., are expected to spread by Monday to its transmission-making factory in St. Catharines, Ont., and likely an engine plant in Spring Hill, Tenn., that makes the engines for Chevrolet Equinox models. The Globe's Greg Keenan writes that between 300 and 400 Unifor members in St. Catharines make transmissions for Cami Automotive. Suppliers such as Magna International are also affected. Magna's Qualtech plant in London, Ont., supplies the seats for the Equinox, but 300 employees are being told to stay home while the strike is on. Two of Magna's Cosma International metal-stamping plants in St. Thomas, Ont., have also stopped shipping parts to Cami. The strike began Sunday when Unifor and GM negotiators could not agree on job-security language in a new contract, specifically that Cami be designated as the lead plant for the next redesign of the Equinox. As the lead plant, it would be the first to receive hundreds of millions of dollars in new investment when the vehicle is redesigned in the mid-2020s. No official negotiations are scheduled.
