Collingwood Shipbuilding was a major Canadian shipbuilder of the late 19th and 20th centuries. The facility was located in the Great Lakes and saw its business peak during the Second World War. The shipyard primarily constructed lake freighters for service on the Great Lakes but also constructed warships during the Second World War and government ships postwar. The shipyard was closed permanently in 1986 and the land was redeveloped into a new housing community.
