General Motors of Canada Ltd.
Walkerville, 1918

GM of Canada Ltd., was incorporated in Nov., 1918 and began production in Oshawa, Ontario. Its Walkerville subsidiary, Canadian Products Ltd., was built in 1919 and began producing motors, axles and transmissions for the McLaughin-Buick, Chevrolet FB, Chevrolet 490 and the Oakland 6 automobiles. 

General Motors eventually took over the plant and turned it to the production of trucks and a new six-cylinder Chevrolet engine. Passenger cars were assembled in Windsor for a brief period spanning 1928-29. 

GMC trucks and buses were assembled at the Fisher Body plant from 1930 to 1932, prior to the formation of the General Motors Truck Division in Pontiac, Michigan. Various components have been made continuously since then with a transmission plant and trim plant currently in operation.
