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 Peel Region

Peel Region — comprising Mississauga, Brampton, and Caledon — contains one of the largest concentrations of industrial and logistics space in Canada, anchored by the lands surrounding Toronto Pearson International Airport.

Multi-Residential Development in Peel Region

Multi-residential development across the region is concentrated in Mississauga's City Centre, Brampton's downtown and Bramalea nodes, and emerging mixed-use centres near planned transit expansions. 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 Peel Region

The redevelopment pressure on Peel Region'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.
