The St. Michael’s Hospital and the Hospital for Sick Children, each have helipads that provide vital critical and trauma care service to the City of Toronto and surrounding areas. The protection of the flight paths for these helipads from intrusions caused by development is necessary to ensure their continued and effective operation.

On December 5, 2017, pursuant to an agreement entered into under section 5.81 of the Aeronautics Act (Canada), City Council enacted by-law 1432-2017 to regulate the use of lands in the vicinity of St. Michael’s Hospital and the Hospital for Sick Children. By-laws made by a municipality under an agreement entered into under section 5.8.1 of the Aeronautics Act (Canada) are applicable law for the purposes of issuing a building permit. This means that a building permit will not be issued for a development within lands within the vicinity of St. Michael’s Hospital and the Hospital for Sick Children unless the development complies with by-law 1432-2017 (and other applicable law).

The following are the minimum submission requirements to demonstrate compliance with by-law 1432-2017.

    2. An overlay map showing where the building is in relation to the flight path;
    3. A review of the construction methodology including crane swings and analysis and confirmation that that crane will not breach the Obstacle Limitation Surfaces;
    4. Where a crane is not proposed for the construction of upper storeys of the building due to proximity to the Obstacle Limitation Surfaces, confirmation of alternative construction method must be provided;
    5. Confirmation that maintenance and use of the building including any equipment to be used for maintenance of the building (i.e. window washing equipment, lighting, etc) may be undertaken without breaching the OLS;
