CSA Z768-01 tends to serve financing and transaction needs, while O. Reg. 153/04 governs filings such as a Record of Site Condition or a permit application.
Phase 1 ESAs in London are prepared here using records review, a site visit and interviews to flag potential contamination, with no sampling involved at this stage. We work from our Vaughan head office, roughly 173 km away, so site attendance is straightforward rather than an added cost.
For the complete process and report structure, see the Phase 1 ESA page.
A Phase 2 ESA follows when a concern is identified — see our Phase 2 ESA page for London.
