East GTA Utility

Utility corridors in the East Greater Toronto Area are defined by the fact that two of Canada’s four nuclear power plants are here. These plants feed into a 500 kilovolt electrical transmission (“hydro”) corridor that acts as a backbone to Ontario’s electricity system. Coupled with lower voltage hydro to serve the east GTA cities, as well as some oil and gas pipelines, these form corridors totalling 225 kilometres in length, and covering over 2,000 hectares.

The corridors are listed below.

Notes and Disclaimers

• This is interpretive and not based on official property ownership or rights information from any utility or government entities. This data is provided ‘as is’; please refer to the licenses and additional disclaimers at the Open Data page.
• Some utility corridors are not plainly defined by property boundaries, and may cross or abut private property, roadways and railways. Some interpretive liberties were taken. Furthermore, corridors were drawn in an estimated manner, as parcel data is not publicly available.
• Pipelines are often found within hydro corridors. These are identified primarily as hydro corridors, while pipeline corridors are identified as corridors where hydro lines are not present. Identifying a hydro corridor does not confirm the presence or absence of pipelines.
• While this page advocates for greater public access, utility corridors are private property and this page does not suggest they are all publicly accessible. Please observe all signage respecting access and activities permitted within these corridors. Remember that high voltage power lines and high pressure pipelines can be dangerous to you and the environment.
