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 Pickering

Pickering's industrial lands are concentrated in the Brock Industrial Park in the city's north end, along with distribution facilities near Highway 401 and Brock Road.

Multi-Residential Development in Pickering

The Kingston Road and Brock Road corridors carry an expanding cluster of mid-rise and high-rise condominium development, alongside established apartment buildings near the Pickering waterfront and GO station. 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 Pickering

The redevelopment pressure on Pickering's older commercial and industrial land — a pattern seen across much of Ontario as municipalities intensify around transit and existing infrastructure — means environmental due diligence is an increasingly routine step in local development approvals.

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.

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.
