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 Orillia

Orillia's industrial and commercial base runs along West Street and Highway 11, serving the city's role as a service centre between Lake Simcoe and Lake Couchiching.

Multi-Residential Development in Orillia

Multi-residential development is concentrated near the downtown waterfront and along the West Street corridor, with several mid-rise apartment buildings serving the city's year-round and seasonal population. 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 Orillia

In Orillia, as in most established Ontario communities, a Phase 2 ESA is most often triggered by a property's proximity to active or former industrial, automotive, or fuel-handling uses, or by a proposed change to a more sensitive land use.

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.

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.
