What Stephenson Engineering does

Stephenson Engineering is a Canadian structural consulting firm founded in 1969 and headquartered in North York (Toronto), with additional offices in Ottawa, Calgary, and Vancouver. The firm provides full-service structural engineering for buildings, with a portfolio spanning 8,000+ projects over more than 50 years, and is staffed by approximately 250 registered engineering professionals. Its client base includes large Canadian real estate developers, REITs, institutional investors, and corporate occupiers across real estate, healthcare, government, technology, automotive, and education segments.

The firm has extended beyond pure consulting into proprietary structural systems, including the Mega Delta Frame co-developed with CAST CONNEX and the Intelligent Structural Panel, an instrumented structural product aimed at smart-building applications. Project work has earned industry recognition, including the Schreyer Award, and the firm maintains long-running relationships with marquee developers and institutional clients such as Menkes Developments, Allied Properties REIT, GWL Realty Advisors, HOOPP Realty, Microsoft Canada, and BMW Canada.

Since September 2021, Stephenson has operated as part of the Salas O'Brien platform, a multi-disciplinary engineering organization with 950+ team members, which has materially expanded the firm's cross-discipline capacity and geographic reach. The business model is project-based professional services revenue, with fees tied to the size and complexity of structural scopes on commercial, residential, institutional, and corporate campus developments; the firm monetizes primarily through consulting fees, with incremental upside from participation in differentiated, IP-adjacent structural systems.
