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 Windsor

Windsor's industrial base is dominated by automotive manufacturing along Walker Road and the Ojibway Parkway corridor, reflecting the city's century-long role as a cross-border auto manufacturing hub.

Multi-Residential Development in Windsor

Multi-residential development is concentrated in the downtown core and along Ouellette Avenue, with a mix of established and newer mid-rise apartment buildings throughout the city. 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 Windsor

The redevelopment pressure on Windsor'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.
