Building Near Metrolinx - Guidelines and Permits

Development projects adjacent to Metrolinx rail corridors


Metrolinx is involved with the review of adjacent development projects in order to safeguard the integrity of our rail corridors, ensure that all development proceeds in a safe manner, and confirm that associated construction activities do not interfere with the existing and future operation, maintenance, and expansion of Metrolinx transit services – including GO Transit, UP Express, Light Rail Transit (LRT), Subways, and Priority Transit Projects.

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.

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.
