We review York Region properties under a Phase 1 Environmental Site Assessment through document review, a site walk and interviews — non-intrusive, with no sampling done. Because our Vaughan head office is 11 km or so away, getting to site doesn't add cost or delay.
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 York Region.
