Defence Industries Limited

DIL set up facilities in St. Paul l'Hermite and Ste Thérèse, Quebec, to fill shells with explosives.

[6] By the end of the war, the workers had filled more than 40 million percussion caps, detonators, bombs, anti-tank mines, armour-piercing and anti-aircraft shells.

[7][8] Although the houses built for the DIL employees were intended to be temporary, after the war the occupants petitioned to buy them, and, after permanent foundations were built, the homes became part of a new town, which was named Ajax after HMS Ajax (22), a light cruiser of the Royal Navy during World War II.

DIL was contracted by the federal government to co-ordinate the construction and operation of Chalk River Laboratories, a pilot plant for the production of plutonium using heavy water as a moderator, which was being built in northern Ontario as part of the Manhattan Project.

[10] In 1947, operation of the partially completed facility was taken over by the National Research Council; a number of DIL employees were hired by the NRC to provide continuity in the process.
