Should Building Heights Near Toronto Hospitals Be Changed for 636 Bay St. Development?
Official title: Request for an amendment to Minister’s Zoning Order, Ontario Regulation 10/24, City of Toronto
Property owners at 636 Bay St., 70 and 100 Edward St. in downtown Toronto want to build taller than current rules allow. The catch? Those rules exist to protect air ambulance flight paths for St. Michael's Hospital and SickKids. The Minister is asking whether to grant an exception.
Why This Matters
Live or work near Bay and Dundas? This could change your skyline. More importantly, air ambulances fly patients to these hospitals in emergencies. Any building changes need to keep those flight paths safe. If you've ever needed emergency care downtown, you know why this matters.
What Could Change
If approved, the zoning map would be amended to allow taller buildings at these specific addresses. The current regulation caps heights to protect helicopter landing paths. An exception here could set precedent for other downtown sites seeking similar amendments.
