What Dillon Consulting does

Dillon Consulting Limited is a Canadian employee-owned professional consulting firm founded in 1946 and headquartered in Toronto, Ontario, providing planning, engineering, environmental science, and architecture services to government and private sector clients. The firm operates through 25+ offices across all 10 Canadian provinces and territories with 1,100+ employees, delivering eight integrated service lines: Architecture, Community Planning & Infrastructure, Contaminated Sites Management, Environmental Management, Facilities, Land Development, Transportation, and Waste Management.

The company generates revenue through project-based professional services contracts, typically won via competitive government RFPs and direct client negotiations, with multi-year contract cadence on major infrastructure programs. Its 100% employee-ownership model, with over 60% of staff holding shares, is a defining structural feature established by the founders. Service delivery has been expanded through a programmatic M&A strategy, including Counterpoint Engineering (2021) for land development, Internat Energy Solutions Canada (2023) for energy and decarbonization, and FBM Architecture (2025) for in-house architectural design and Atlantic Canada presence.

Dillon's primary customer base consists of municipal, provincial, and federal government agencies (e.g., City of London, City of Guelph, Manitoba Transportation and Infrastructure) and Indigenous communities across Canada (e.g., God's Lake First Nation, Weenusk First Nation, Nahanni Butte Dene Band), with a smaller private sector segment. The firm has sustained Canada's Best Managed Companies Platinum Club status from 2006 through 2025, ranks on Engineering News-Record's Top 200 Environmental Firms, and has been recognized across consecutive Best Workplaces categories by Great Place to Work.
