Ontario Electricity and Natural Gas Utilities - Service Area Map

Natural gas and electricity utilities have to obtain approval from the OEB to operate their systems in a given area (called “service area” or “service territory”). 

When a natural gas utility is approved, the OEB grants a “certificate of public convenience and necessity” (certificate). Electricity utilities, which are licensed by the OEB, receive approval through their licence.

This interactive map provides information about where certificates and licences have been granted in the province.

    Section 8(1) of the Municipal Franchises Act states that a Certificate is necessary before any person can construct works to supply gas in a municipality.

    The Certificate grants the right to construct infrastructure for the purposes of supplying gas to consumers in the service territory specified. The applicant must show that there is public convenience and necessity.
