What is a Phase 1 Environmental Site Assessment?

A Phase 1 ESA is a non-intrusive investigation to identify potential environmental contamination risks on a property. No soil sampling or laboratory testing is conducted at this stage.

See our Phase 2 ESA page for more. In Ontario, the CSA Standard applies to real estate due diligence and financing; O.Reg. 153/04 applies to rezoning, building permits, or filing a Record of Site Condition.

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 1 ESA when they change ownership, are refinanced, or are proposed for redevelopment to a more sensitive use such as residential.

How a Phase 1 ESA Is Actually Carried Out

In practice, the site reconnaissance is conducted by a qualified environmental professional who documents visible evidence of contamination, examines drainage patterns and surface staining, and notes the condition of any storage tanks, drums, or waste materials on site.

Interviews are conducted with the current property owner or operator, and where possible with previous owners or long-term employees, to capture institutional knowledge of past spills, storage practices, or waste handling that may not appear in the written record.
