Cambium

What Cambium does

Cambium Inc. is a privately held Canadian consulting and engineering firm founded in 2006 in Peterborough, Ontario, and acquired by Englobe's Canadian engineering platform in June 2025. The firm operates as a multi-disciplinary professional services platform, delivering integrated engineering, environmental, and building science services rather than packaged software or products. Core service lines include Hydrogeological/Water/Wastewater Treatment, Site Assessment/Risk/Remediation, Construction Testing & Inspection, Waste Resources Management, Building Sciences, Air & Acoustics, Natural Sciences, Geotechnical services, Source Water Protection, and a CCIL-certified materials testing laboratory. Services are delivered through approximately 200 employees across five Ontario offices (Barrie, Kingston, Ottawa, Peterborough, Whitby), with customers spanning municipal governments, industrial and manufacturing operators, commercial real estate developers, mining operators, and institutional clients.

The firm's underlying technology is a CCIL-certified materials testing laboratory for aggregates, asphalt, concrete, mortar, grout, and soils, combined with deep Ontario-specific regulatory expertise across the Environmental Assessment Act, O.Reg. 153/04, O.Reg. 406/19, and Tarion requirements. Revenue is generated through project-based professional consulting fees structured as hourly engagements, fixed-fee contracts, and multi-year service relationships, with no publicly disclosed standard pricing. Go-to-market is sales-led and relationship-based, targeting enterprise and municipal clients primarily through direct engagement, RFP processes, and project-based referrals rather than digital channels. Customer concentration is moderate, spread across multiple verticals but geographically constrained to Ontario. Cambium has appeared on the Globe and Mail's Top Growing Companies list for six consecutive years, reporting 50% three-year growth in 2024 and 94% in 2025.
