To best preserve our cultural heritage legacy in any planning and development context

ASI is a Canadian-owned company that was founded in 1980 in response to increasing public awareness of the importance of the province's heritage. With offices in Toronto and Burlington, we are the largest archaeological and cultural heritage consulting firm in Ontario.

Pre-Development Assessments

Our team of provincially licensed archaeologists and cultural heritage specialists provide expert archaeological and cultural heritage evaluations.

Archaeological Excavations

When protection of sites isn't possible, our archaeologists call on their unparalleled expertise to conduct Stage 4 mitigative excavations throughout Ontario.

Heritage Planning

Our cultural heritage specialists offer a range of consulting services in built heritage and cultural landscape conservation, planning and management.

Policy Development

ASI are industry leaders in the development of archaeological and cultural heritage landscape policy and guidelines for municipal, regional and provincial clients.

The Authority of Experience

We have completed over 5,000 projects throughout Ontario, and with a full time, permanent, staff of over 50 individuals and an additional seasonal staff of up to approximately 50 field technicians, we have the logistical and human resources necessary to bring any cultural heritage management project to fruition.

Feature Film

Hangman’s Graveyard

ASI was retained to find, exhume and rebury those men who had been hanged at Toronto’s Don Jail as part of the Bridgepoint Hospital redevelopment project. Our work was followed by Ballinrun Productions film crew, under the direction of Mick Grogan, and the film shows ASI archaeologists in both the field and the lab.
