Newly built cars sit in a shipping lot near General Motors Car assembly plant in Oshawa, June 1, 2012. General Motors Co said on Friday it expects to close one of the two lines at its Oshawa, Ontario, assembly plant by June 1, 2013. The consolidated assembly line, which employs about 2,000 workers, was originally expected to cease production in 2008, GM said in November 2005. But production was extended due to market demand for the Chevrolet Impala and Chevrolet Equinox crossover, GM said. REUTERS/Mark Blinch (CANADA - Tags: TRANSPORT BUSINESS EMPLOYMENT)
