What Leroux+Cyr does

Leroux+Cyr is a Montréal-based civil engineering firm founded in 2014 that provides building structure engineering services. The practice is led by its two co-founders, Guillaume Leroux and Charles-Etienne Cyr, both associate engineers, and operates with a headcount in the 11-50 range, placing it firmly in the small-firm segment of the Quebec structural engineering market.

The company's product surface is professional engineering services rather than a packaged software or product line. Its underlying work consists of structural analysis and design for buildings — load calculations, member sizing, connection detailing, and production of construction documents — delivered to clients such as architects, developers, general contractors, and property owners. The firmographic profile indicates it is a for-profit private company with no disclosed subsidiaries, funding rounds, or parent organization.

The business model is project-based fee-for-service engineering, which is standard for the sector. No pricing model, contract structure, marketing channels, or customer segmentation is documented in the available data, and the firm's website returned only a verification loading page during data collection, limiting visibility into recent activity, client roster, and revenue mechanics.

Broad incumbents

• Stantec: Major Canadian engineering, architecture, and environmental services firm with structural engineering practices across Canada. Overlaps with Leroux+Cyr on building structure work but offers a much wider multidisciplinary portfolio and international footprint.
• AECOM: Global infrastructure consulting firm with significant structural engineering practices serving building, transportation, and water projects. A broad incumbent whose Canadian operations compete with boutique firms like Leroux+Cyr on larger institutional work.
• WSP Global: Canadian-headquartered global engineering consultancy with extensive structural and building services capabilities. Competes with Leroux+Cyr on Quebec institutional and commercial projects but at significantly larger scale and broader scope.
• AtkinsRéalis: Formerly SNC-Lavalin, a large Quebec-based engineering and project management firm with substantial building and infrastructure structural engineering capabilities. A broad incumbent competing for both private and public-sector structural mandates.
• CIMA+: One of Canada's largest privately held engineering consulting firms with a strong Quebec base across structural, civil, and multidisciplinary work. Operates as a larger incumbent offering broader service lines than Leroux+Cyr but competes for the same structural engineering mandates.
• EXP: Canadian-headquartered multidisciplinary engineering and architecture firm with structural engineering services across buildings and infrastructure. A larger incumbent with overlapping service lines but broader geographic and disciplinary reach.
• Arup: Internationally recognized engineering consultancy with deep structural engineering expertise in complex buildings. A broad incumbent whose high-profile structural work and technical brand set the benchmark Leroux+Cyr would be measured against.

Direct peers

• Bouthillette Parizeau: Montreal-based engineering firm specializing in structural and MEP design for buildings. Comparable to Leroux+Cyr by virtue of shared Quebec geography, structural-engineering focus, and similar boutique scale serving institutional and commercial clients.
