What ASI | Providing Archaeological & Cultural Heritage Services does
ASI Heritage (legal name Archaeological Services Inc.) is a Canadian-owned archaeological and cultural heritage consulting firm headquartered at 528 Bathurst Street in Toronto, with a second office in Burlington, Ontario. Founded in 1980 by Dr. Ron Williamson, ASI delivers pre-development archaeological assessments, Stage 4 mitigative excavations, built heritage and cultural landscape conservation, archaeological management plans, geomatics and remote sensing, marine archaeology, Indigenous engagement, policy development, and litigation support services. The firm self-identifies as the largest archaeological and cultural heritage consultancy in Ontario, with a permanent staff of more than 50 plus up to approximately 50 seasonal field technicians, and a track record of more than 5,000 completed projects across the province. Client work spans high-profile infrastructure (Ontario Ministry of Transportation's Highway 407 and Seaton Lands), municipal management plans (City of Toronto, City of Windsor, City of London, Town of Caledon), private development (Concord Adex's CityPlace), and historical archaeology on over 400 provincially significant properties under the Ontario Heritage Trust.
The firm operates as a project-based professional services consultancy. Revenue is generated through quote-based, project-specific engagements with three primary customer groups: provincial and municipal government agencies, private developers, and Indigenous communities. Pricing is not publicly disclosed; contracts are procured via direct sales, professional reputation, RFP-style municipal procurement, and engagement through partnerships (e.g., the 2020 Yändata' framework with the Huron-Wendat Nation). Go-to-market leverages a professional website, active social channels (LinkedIn, Instagram, YouTube, Facebook, X), participation in conferences such as the Ontario Archaeological Society Symposium and Society for American Archaeology, and brand-building through documentary film productions. Core technical capabilities center on provincially licensed archaeological expertise, GIS-based geomatics and remote sensing, and domain specialization in Stage 4 mitigative excavations and Indigenous consultation protocols.
ASI is led by Managing Partner Robert I. MacDonald, who succeeded founder Dr. Ron Williamson on October 1, 2016, alongside five new partners (Katherine Hull, Lisa Merritt, Andrew Riddle, David Robertson, Rebecca Sciarra). Ownership remains private under a partnership structure typical of professional consultancies; the company has no public ticker, no parent, no subsidiaries, no funding rounds, and no M&A activity disclosed. The firm's recognition includes the 2016 Archaeological Institute of America Conservation and Heritage Management Award for the Toronto Archaeological Management Plan, the 2019 Heritage Toronto Special Achievement Award, multiple Ontario Archaeological Society recognitions, and the 2024 Thomas Symons Award for Dr. Williamson.
