Simex Defence

What Simex Defence does

Simex Defence Inc. is a Canadian-owned, founder-controlled defence procurement and sourcing company headquartered in Pointe-Claire, Quebec, founded in 1994 by Sam Mouallem. The company operates as an intermediary between global defence OEMs and Canadian government buyers, specializing in the sourcing of hard-to-find and legacy defence parts, NSN-based procurement, on-demand manufacturing using an in-house technical drawing database, warehouse-based inventory management in Montreal, kitting and assembly, and repair and overhaul services including Racal acoustics systems. Its core technology is a proprietary database of over 100,000 National Stock Numbers previously supplied to the Department of National Defence and major Prime Defence Contractors, augmented by exclusive OEM distribution agreements and Controlled Goods plus ISO 9001:2015 certifications.

Simex generates revenue through one-time transactional purchases rather than subscriptions, with pricing set via a formal Request-for-Quote process. The company executes approximately 1,000 defence contracts annually, with recent individual contract wins disclosed at over 5 million CAD (military armoured vehicle communications), over 2.4 million CAD (DND radios), and a multi-million standing offer for AN/PVS-14 night vision spares. Customers are heavily concentrated in the Canadian federal government (DND, Canadian Armed Forces, Public Services and Procurement Canada, Transport Canada, Canadian Coast Guard) with secondary exposure to NATO/NSPA, the US Defense Logistics Agency, and major defence primes including L3 HARRIS MAS as an approved vendor.

The business operates a sales-led, relationship-driven go-to-market with approximately 25-40 staff, supported by a public NSN Catalog search platform, participation in Canadian defence trade shows such as CANSEC and DEFSEC, and a direct RFQ-based sales channel. Family ownership is concentrated among the Mouallem and Dagher families across President, Operations, Finance, and Business Support functions, with no disclosed institutional investors or external funding.
