What is a Phase 1 Environmental Site Assessment?

A Phase 1 ESA is a non-intrusive investigation to identify potential environmental contamination risks on a property. No soil sampling or laboratory testing is conducted at this stage.

See our Phase 2 ESA page for more. In Ontario, the CSA Standard applies to real estate due diligence and financing; O.Reg. 153/04 applies to rezoning, building permits, or filing a Record of Site Condition.

Industrial and Commercial Context in Peterborough

Peterborough's industrial base runs along the Technology Drive and Lansdowne Street corridors, alongside established manufacturing lands near the Otonabee River reflecting the city's long industrial history.

Multi-Residential Development in Peterborough

Multi-residential development is concentrated near downtown and along Lansdowne Street, with several mid-rise apartment buildings serving the city's Trent University and Fleming College populations. Properties near these commercial and industrial corridors are the ones most likely to require environmental due diligence before financing, redevelopment, or a change of use.

Why This Matters for Properties in Peterborough

As with any Ontario municipality with an established industrial base, properties near Peterborough's commercial and industrial corridors are more likely to require a Phase 1 ESA when they change ownership, are refinanced, or are proposed for redevelopment to a more sensitive use such as residential.

How a Phase 1 ESA Is Actually Carried Out

In practice, the site reconnaissance is conducted by a qualified environmental professional who documents visible evidence of contamination, examines drainage patterns and surface staining, and notes the condition of any storage tanks, drums, or waste materials on site.

The historical records review typically draws on fire insurance plans, aerial photographs spanning several decades, and prior environmental reports where available, cross-referenced against the property's chain of title to identify past uses that might not be apparent from a site visit alone.
