Non-potable requests for brownfield development

Where to send notice of intention has changed

A brownfield is an industrial or commercial property that is – or could be – contaminated. Common brownfields are former factories, gas stations, dry cleaners, and land where a chemical spill took place.

A brownfield might need to be cleaned up before it can be redeveloped.

Ontario Ministry non-potable site condition standards

The Ontario Ministry of the Environment and Climate Change (MECP) has developed non-potable site condition standards for brownfield redevelopment.

These standards are for properties where a municipal supply of drinking water is available and there are no wells in the area. Submitting a request ensures that applying non-potable site condition standards will not put local water supplies at risk.

Sending notice of intention for brownfield redevelopment

When a brownfield is being redeveloped for a more sensitive use, such as residential development, the property owner must, under Ontario Regulation 153/04, notify regional municipalities of their intent to use non-potable site condition standards.

In keeping with O.Reg. 407/19 (Amending O.Reg. 153/04)s.13, as of July 1, 2020, the type of municipality to send notice of intention to apply the non-potable groundwater site conditions standards has been revised:

  • If the property is in a single tier municipality, send the notice of intention to the single tier municipality.
  • If the property is in a two tier municipality, send the notice of intention to whichever municipality has authority under the Municipal Act, 2001 to pass bylaws respecting water production, treatment, and storage.
