Third Party Projects Review

Building near a Metrolinx transit corridor

If you are a property owner who plans to build on or develop lands that are near one of Metrolinx’s existing or planned transit corridors, you may need to get approvals or a Corridor Development Permit from Metrolinx to do so. These corridors include:

GO Transit / UP Express rail

Light Rail Transit (LRT)

Subways

Metrolinx will help you ensure that your plans follow all necessary guidelines, requirements and standards, and that you have all the necessary permits in place to safely proceed with construction in a way that does not interfere with nearby transit plans.

The benefits to you

Submitting your plans to Metrolinx for approval helps avoid conflicts with nearby transit projects, ensuring work is done safely and reducing the likelihood that you might have to stop or redo your work in the future.

Metrolinx is committed to working with you to ensure all necessary safeguards are in place before any work is started so that you can have greater certainty and predictability over your plans.
