Sonaca Montreal

Sonaca Montréal is a specialist manufacturer in the aerostructures segment, primarily focused on the production of large-scale wing components and complex integrated assemblies. As a key tier-one and tier-two supplier within the global aerospace value chain, the organisation occupies a specific niche in high-precision machining and the assembly of wing stringers and spars for narrow-body and regional aircraft. The company serves as a critical partner to major original equipment manufacturers, most notably providing structural components for the Airbus A220 programme (formerly the Bombardier CSeries). Its customer base extends to other global airframe manufacturers including Boeing and Embraer, supporting commercial, business, and regional jet platforms. The facility operates as the North American strategic hub for its European parent organisation, facilitating local supply chain integration for transatlantic projects. Prospective buyers should verify the organisation’s specific NADCAP certifications for special processes and their current capacity for high-velocity machining of long-bed aluminium components. It is essential to confirm the status of their quality management systems regarding AS9100 standards and their specific logistical capabilities for transporting oversized aerostructures to final assembly lines across North America.
