Diemaco was a Canadian defence company based in Kitchener, Ontario, that manufactured the C7 family of rifles under a licence from Colt.

History

The company was formed in 1974 under Devtek Corporation, effectively replacing the arms supply from government owned Canadian Arsenal Limited.

In 2000, it was acquired by Héroux-Devtek Inc.

On May 20, 2005, it was acquired by Colt Defense for $18.2 million. As a result, Héroux-Devtek revamped the Aerospace and Defense division to the Aerospace division.

Colt Canada relaunched the brand in 2014.
