Request for an Amendment to Minister’s Zoning Order, Ontario Regulation 10/24, City of Toronto

A Minister’s Zoning Order (MZO), made pursuant to clause 47(1)(a) of the Planning Act, regulates the use of land and the erection, location and use of any building or structure on the land.

Ontario Regulation (O. Reg.) 10/24 protects public health and safety by regulating building heights to ensure the safe operation of air ambulance services provided in relation to St. Michael's Hospital and The Hospital for Sick Children. The zoning order prohibits any building, structure or naturally growing object from penetrating into the obstacle limitation surfaces for the St. Michael's Hospital Heliport and The Hospital for Sick Children Heliport, subject to the exceptions listed in the order.

O. Reg. 10/24 applies to those lands subject to the obstacle limitation surfaces for the St. Michael's Hospital Heliport and those lands subject to the obstacle limitation surfaces for The Hospital for Sick Children Heliport, as shown on the existing maps referenced in the regulation, identified below.

The Minister is considering a request from the Minister of Health to amend Ontario Regulation 10/24. If made, the amendment to the MZO would:

• Remove section 5 of the order that requires that O. Reg. 10/24 be revoked on May 30, 2025

This amendment request is related to ERO proposal 025-0348 in respect of requests for site-specific amendments and minor technical amendments to Map Nos. 345 and 346 that form part of O. Reg. 10/24.

To help ensure decisions are made in a transparent manner and support government priorities, the Ministry is seeking feedback on whether this request should be considered and any additional information that may help inform a decision. This consultation is limited in scope to the proposed removal of the expiry date, and submissions related to further amendments to the MZO will need to be submitted per the ministry’s Zoning Order Framework.
