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 Burlington

Established industrial space runs along Appleby Line and the QEW corridor in the city's east end, though large sections of this employment land — including at Appleby Line and Fairview Street — are being redesignated for mixed-use redevelopment.

Multi-Residential Development in Burlington

Burlington's Uptown area at Appleby Line and Upper Middle Road has become a major condominium node, with projects such as 1989 Appleby Line (two towers, roughly 462 units) and 1900 Appleby Line (three towers, roughly 560 units) among several multi-storey developments reshaping former industrial and commercial land along the 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 Burlington

The proposed redevelopment at Appleby Line and Fairview Street — converting former industrial land and a plaza into a multi-tower community that could house up to 25,000 residents — is a clear example of the kind of large-scale industrial-to-residential conversion that requires a full ESA process before rezoning can proceed.

How a Phase 2 ESA Is Actually Carried Out

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.

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.
