What Blackwell does

Blackwell Structural Engineers is a Toronto-headquartered structural engineering consulting firm founded in 1987, serving architects, developers, government agencies, institutions, and private clients across Canada and selectively in the United States. The firm delivers full-scope structural services spanning schematic design, design development, contract documentation, shop drawings, contract administration, feasibility studies, peer reviews, and site visits, using timber, steel, concrete, masonry, and tensile/fabric structural systems. It operates from offices in Toronto, Waterloo, Halifax, Windsor, and Victoria, with a staff of 51–100 that includes licensed P.Eng. principals and BIM technologists.

Blackwell's commercial differentiation rests on three specialty practices: mass timber design (CLT, DLT, NLT, GLT) including the first mass timber project to clear Toronto approvals and the longest manufactured CLT panels in Canada; fabric and tensile structures using SolidWorks-based 3D modeling with PVC, PTFE, ETFE, and HDPE fabrics; and heritage building rehabilitation, materially deepened by the June 2024 acquisition of Ojdrovic Engineering, which brought Parliament Hill West/East Block, Supreme Court of Canada, and Province House into the portfolio. Sustainability is positioned through an SE2050 Program commitment, embodied carbon analysis using BIM and Environmental Product Declarations, and BubbleDeck concrete-volume reductions of up to 35%.

The firm operates as a project-based professional services business with no published pricing; fees are negotiated per scope. Revenue derives from architectural firm partnerships (the dominant referral channel), direct developer and institutional engagements, and government procurement for heritage work. Marketing is largely portfolio- and award-driven, with consistent recognition across Wood Design & Building Awards, RAIC Governor General's Medals, OAA Design Excellence Awards, CISC steel awards, and the Holcim Foundation. Brooke Guzar, appointed inaugural CEO in March 2023, leads the firm.
