Phase 1 Environmental Site Assessments in Toronto
Phase 1 ESAs for Toronto properties are matched to CSA Z768-01 or O. Reg. 153/04 depending on what the report is for.
Phase 1 Environmental Site Assessments in Toronto
CSA Z768-01 is typical for financing and transactions; O. Reg. 153/04 applies where the outcome feeds a Record of Site Condition, a rezoning, or a municipal application.
We review Toronto properties under a Phase 1 Environmental Site Assessment through document review, a site walk and interviews — non-intrusive, with no sampling done. Site attendance is routine rather than a special trip, with our Vaughan head office 11 km or so away.
The Phase 1 ESA page explains the process and the report in full.
A Phase 2 ESA follows when a concern is identified — see our Phase 2 ESA page for Toronto.
