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 Simcoe County

Simcoe County's industrial base is distributed across its member municipalities, with concentrations in Barrie, Collingwood, and Bradford, reflecting a mix of manufacturing, agriculture-support, and tourism-related industry.

Multi-Residential Development in Simcoe County

Multi-residential development varies significantly by municipality within the county, with the largest concentrations of apartment and condominium buildings found in Barrie and Orillia. 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 Simcoe County

Properties located near or formerly used for industrial or automotive purposes in Simcoe County are the ones most commonly flagged for further environmental investigation during a real estate transaction, rezoning application, or building permit review.

How a Phase 1 ESA Is Actually Carried Out

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.

Interviews are conducted with the current property owner or operator, and where possible with previous owners or long-term employees, to capture institutional knowledge of past spills, storage practices, or waste handling that may not appear in the written record.
