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. 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.
