Canadian Vickers Limited was an aircraft and shipbuilding company that operated in Canada during the early part of the 20th century until 1944. A subsidiary of the UK parent, it built its own aircraft designs as well as others under licence. Canadair absorbed the Canadian Vickers Ltd. aircraft operations in November 1944.
British ship building and weapons manufacturing conglomerate Vickers Sons & Maxim was invited by the Government of Canada in 1911 to establish a Canadian division to manufacture vessels for the nascent Royal Canadian Navy. Vickers Sons & Maxim established Canadian Vickers Ltd. and constructed Maisonville Shipyard at Viauville (Mercier–Hochelaga-Maisonneuve) in the east end of Montreal near Boulevard Viau and rue Notre-Dame Est.
Today the old shipyard buildings are gone replaced by silos and port facilities now owned by the Port of Montreal.
During World War I the yard built the Holland 602 type submarine for the British and the Italian Navy. They were known as the British H Class submarine in the Royal Navy
