About Groupe DCM
Groupe DCM supplies aircraft structural parts and assemblies, electrical test tooling, maintenance tooling and aerospace repair services. Its Canadian operations combine several specialist manufacturing businesses acquired into a broader aerospace group.
Operating context
DCM’s range spans production hardware and the tooling used to manufacture or maintain aircraft. The group’s site records Koss Aerospace and Brampton Processing acquisitions in 2024 and Metcor in 2025, making the responsible operating site an important purchasing distinction.
Canadian footprint
The corporate contact is in Saint-Bruno, Québec. DCM lists aerospace operations in Montréal, Saint-Bruno, Blainville, Brampton and Toronto, plus Metcor’s Québec heat-treatment operations; Toulouse is a separate French location.
