What is the Toronto Ravine and Natural Feature Protection By-law, and does it affect my lot?
Answered by AskBaily Editorial · Updated
Short answer
By-law 407-2012 protects Toronto's ravine system — the Don, Humber, Rouge, Highland Creek, Mimico Creek, and smaller tributaries plus their tabletop lands. Any major renovation on a ravine-adjacent parcel (Hoggs Hollow, Rosedale ravines, High Park edges, Bayview Village) requires a separate Ravine Protection permit through Urban Forestry. Typical ravine permit adds 8-20 weeks and can require arborist, geotechnical, and natural-heritage reports.
