Metrolinx Corridor Development Permit Guideline for Adjacent Development

Depending on your project parameters, Metrolinx development agreements may be required to specify technical requirements, roles, and responsibilities. Agreements may be required, for example, to address general Adjacent Development matters, Crane Swing activity, and/or Shoring/Tieback installations. Applicability and content will vary depending on the nature of the development activity in question.

Metrolinx staff will assist with document refinement, and this process can begin at any time during the planning process, although it should be noted that these agreements must make reference to final project plans and, as such, finalization of the documents usually occurs in the latter stages of planning approvals.

Metrolinx Legal typically requires six (6) weeks for review of the final document, although this may vary depending on the complexity of the issues contemplated. Revisions to the Metrolinx template documents are discouraged to expedite the review process.

Metrolinx’s fees and agreement requirements have been updated and will be effective as of September 1, 2023. For more information regarding key considerations, fees, and insurance requirements associated with each type of development agreement, please review the Additional Information for Development Agreements.
