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 Cambridge

Cambridge's industrial heritage runs through Preston and Hespeler along the Grand and Speed Rivers, where former textile and manufacturing sites continue to be redeveloped, alongside active manufacturing areas near Franklin Boulevard and Eagle Street.

Multi-Residential Development in Cambridge

The Hespeler Road corridor is the city's dominant commercial and multi-residential spine, anchored by Cambridge Centre, with apartment and condominium buildings concentrated in Preston Centre, Galt City Centre, and Hespeler Village. 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 Cambridge

A proposal to rezone a former Hespeler furniture factory site at 130 Guelph Avenue for a six-storey, 112-unit apartment building illustrates the pattern in Cambridge: aging industrial sites in Preston and Hespeler being converted to residential use, a process that required a two-phase environmental assessment and remediation plan for roughly 200 tonnes of contaminated soil.

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.
