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 Milton

Milton's industrial base has expanded rapidly along the Derry Road corridor and Highway 401 interchange, anchored by large-format distribution centres serving the western GTA.

Multi-Residential Development in Milton

New multi-residential and townhouse development is concentrated in the Milton Education Village and Sherwood/Ford Drive areas, reflecting the town's status as one of Canada's fastest-growing municipalities. 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 Milton

As with any Ontario municipality with an established industrial base, properties near Milton's commercial and industrial corridors are more likely to require a Phase 2 ESA when they change ownership, are refinanced, or are proposed for redevelopment to a more sensitive use such as residential.

How a Phase 2 ESA Is Actually Carried Out

Borehole locations are selected based on the Phase 1 findings, typically targeting areas of suspected historical spills, former tank locations, or drainage points where contaminants would be expected to accumulate.

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.
