What is a Phase 2 Environmental Site Assessment?

A Phase 2 ESA is an intrusive investigation involving borehole drilling, soil and groundwater sampling, and laboratory analysis, typically conducted after a Phase 1 ESA identifies Recognized Environmental Conditions.

See our Phase 1 ESA overview for more. In Ontario, Phase 2 ESAs may follow CSA Z769 (financing, due diligence) or O.Reg. 153/04 (RSC filing, rezoning, MECP applications).

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 2 ESA Is Actually Carried Out

Laboratory results are compared against the applicable Ministry of the Environment, Conservation and Parks site condition standards for the property's actual and intended use, and any exceedances are clearly flagged in the final report along with recommended next steps.

Soil samples are collected at multiple depths from each borehole and screened in the field before being sent to an accredited laboratory, allowing the assessor to prioritize which samples warrant full laboratory analysis.
