UPDATE: GM, Unifor announce investment in Oshawa plant that will save 300 jobs

General Motors Canada says it will invest $170 million dollars in its Oshawa plant to transition the facility from manufacturing vehicles to stamping, sub-assembly and autonomous vehicle testing.

GM Canada President Travis Hester says the move will save 300 of the approximately 2,600 union jobs at the plant.

He made the announcement Wednesday morning in Toronto alongside Unifor national president Jerry Dias.

Dias says it's not perfect and he's still not happy, but this is something that is going to sustain some jobs for the long-term.

GM announced last November it would cease production at the Oshawa plant by the end of 2019.

In March, Unifor suspended a media campaign against GM amid what the union called productive talks with the automaker on the future of the Oshawa plant.

The union said the company had been clear it wouldn't extend vehicle manufacturing at the facility beyond the end of the year, but acknowledged there is potential to transform operations to maintain some jobs.
