West GTA Utility Corridors

Exploring hydro corridors is a key cornerstone of Metroscapes. The western Greater Toronto Area (GTA) is notable in that, in addition to hydro corridors, many pipelines cross-cross the region. While many major hydro corridors usually share space with pipelines, there are 11 pipeline corridors that exist in their own protected right-of-way. This is in addition to 17 corridors that exist with electrical transmission lines being the primary utility.

Mapping and tabulation of the corridors is laid out below. This will be flushed out with greater detail once I explore them more, and I catch up with mapping the metroscapes of the broader GTA that I expanded into during 2024.

Notes and Disclaimers

This data was created with the support of roadway, administrative boundary, and web map service data from Open Data Portals of lower- and upper-tier municipalities of Halton and Peel Regions. This is interpretive and not based on official property ownership or rights information from any utility or government entities. Therefore 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 outside of the City of Mississauga, 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.
