Commitments and Future Work

Following the TPAP phase, the proposed layover will move into detailed design and construction phases. During these phases, all applicable regulations, permits, approvals and best practices will be adhered to. A few of the key preliminary commitments include:

  • A range of municipal permits and approvals may be required for the Project. Metrolinx will obtain all required permits and approvals. However, Metrolinx as a Crown Agency of the Province of Ontario is exempt from certain municipal processes and requirements.
    • In these instances, Metrolinx will continue to engage with the municipalities to incorporate municipal requirements as a best practice, where practical, and may obtain associated permits and approvals.
  • Metrolinx will continue to communicate and engage with impacted municipalities, utilities and services and property owners throughout detailed design and prior to construction, where necessary.
  • An Environmental Mitigation and Monitoring Plan will be developed and adhered to during construction.
  • Surrounding property owners will be informed of anticipated upcoming construction.
  • Field activities, including Stage 3 Archaeological Assessment, Plant Survey, Fish and Fish Habitat Survey and Tree Inventory will be completed in advance of construction.
