Marine Industries

Marine Industries Limited (MIL) was a Canadian ship building company, in Sorel-Tracy, Quebec, with a shipyard located on the Richelieu river about 1 km from the St. Lawrence River. It employed up to 10,000 people during the post WWII boom.

Opened in 1937, the yard saw many contracts during its early years for vessels used on the Great Lakes and Canada's Atlantic coast. In 1986 the federal government asked Quebec to rationalize its shipyards, which saw MIL merge with Davie Shipbuilding in Lauzon; the Sorel shipyard was called M.I.L. Tracy (for Tracy, Quebec) and the Lauzon shipyard was called M.I.L. Lauzon.

Shortly after the merger, the new company, MIL Davie Shipbuilding closed the Sorel shipyard along with the Versatile Vickers shipyard in Montreal, resulting in a total loss of 1,700 jobs.

Ships built
MIL's Sorel shipyard was responsible for numerous Royal Canadian Navy, Canadian Coast Guard and CN Marine vessels.
