In the Greater Toronto Area, our Phase 1 ESA work covers combining a records review, on-site observation and interviews, with no soil or water sampling at this stage. We attend from our Vaughan head office, based in the Greater Toronto Area itself — close enough that a site visit is never the bottleneck.
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 the Greater Toronto Area.
