General Motors Co. plans to respond by Jan. 7, 2019, to Canadian labor union Unifor's proposals to keep an auto assembly plant in Ontario open, Reuters reported Dec. 21, citing union head Jerry Dias.

The site in the city of Oshawa is expected to close in December 2019, but Dias reportedly said there are several solutions to prevent the closure. A spokesperson for General Motors in Canada described the latest meeting as "constructive," according to Reuters.

The Oshawa plant employs about 2,973 workers, the report said.

The plant closure is part of General Motors' restructuring plan, under which the carmaker plans to shut five other North American factories and cut about 15,000 jobs.
