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 Barrie

Barrie's industrial base runs along Bayview Drive, Welham Road, and King Street in the city's north end, with newer distribution and flex buildings continuing to fill in along the Highway 400 corridor.

Multi-Residential Development in Barrie

The city's downtown core along Dunlop Street and the Kempenfelt Bay waterfront has seen a wave of mid- and high-rise condominium construction, while the southern end of Barrie mixes single-family housing with commercial plazas and light-industrial units. 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 Barrie

Barrie's downtown and waterfront redevelopment pipeline, including new business parks and mixed-use projects replacing older commercial buildings, has increased demand for environmental due diligence ahead of rezoning and building permit applications.

How a Phase 1 ESA Is Actually Carried Out

The final Phase 1 report presents the assessor's professional opinion on whether Recognized Environmental Conditions exist, and if so, provides a clear recommendation on whether further investigation — a Phase 2 ESA — is warranted before the transaction, financing, or approval proceeds.

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.
