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 Oakville

Oakville's industrial lands are concentrated along Speers Road and the Ford Drive corridor near the Ford of Canada assembly plant, one of the area's largest employers.

Multi-Residential Development in Oakville

Downtown Oakville and the Kerr Village and Uptown Core areas carry the highest concentration of mid-rise condominium buildings, supplemented by newer development near the Oakville GO corridor. 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 Oakville

The redevelopment pressure on Oakville'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.

Where groundwater is encountered, monitoring wells are installed to allow repeat sampling over time, since a single groundwater sample can be misleading if contaminant concentrations vary seasonally.
