Zone of Influence Map

Please use the Zone of Influence (ZOI) Map to determine whether your proposed project is subject to Metrolinx coordination and permitting requirements. If the project is identified in the ZOI on the map, additional coordination, review, and potential permitting may be required for one or more existing or planned transit corridors.

Simply enter your municipal property address, and the map will identify highlight whether your site is located within a ZOI associated with GO Transit, UP Express, Light Rail Transit (LRT), or Subway corridors.

If your property is outside of all Metrolinx ZOIs, no further action is required.

For additional information regarding review and permitting requirements, please review the website links or contact the Metrolinx Adjacent Construction Review (ACR) Team directly at ACR@metrolinx.com.
