In an effort to supply repeatedly requested information, the Task Force is preparing a series of brief documents/brochures to address these concerns. Back to brochure list.
What we can and cannot do with trees on our properties
Property owners often think that they can do whatever they want on their properties. WRONG! Most know already that they have to obtain permits to build additions to their homes, add an extra bathroom or alter their electrical systems. Trees on private property are protected under two by-laws in the City of Toronto. Note that owners may plant native trees and shrubs and smaller plants as well without permits and are encouraged to do so. Private property may also be subject to the regulations of the Toronto and Region Conservation Authority.
Toronto's Ravine and Natural Feature Protection By-law
The Ravine Protection By-law controls much more than removing or injuring trees. It controls what can be done on any property located within or partially within a ravine protection area. Property owners are required to obtain a permit to take any action to alter the vegetation, place or remove fill or alter the grade in any way, including any type of construction.This by-law protects trees of any size and any species, not just those over a certain size.
Full details to determine if this by-law applies to any property and the application process for any changes property owners wish to make.
Toronto's Private Tree By-law
The City's Private Tree By-law protects trees on private property, outside of ravine protected areas, from injury or destruction. A permit is required to injure or destroy a private tree that has a diameter of 30 cm or greater measured at 1.4 m above ground. A permit is not required to remove dead, terminally diseased or imminently hazardous trees. Pruning private trees using proper arboricultural standards is recommended and does not require a permit. Full details.
Under both by-laws:
- Trees requiring removal because they are deemed to be dead, terminally diseased or imminently hazardous are exempt from the above noted tree by-laws; however, confirmation from Urban Forestry is required prior to proceeding with removal.
- Applications to remove or injure trees must be accompanied by an Arborist Report prepared by a licensed arborist or other professional accepted by Urban Forestry.
- Permits issued to remove or injure trees will be subject to conditions, including tree replacement.
- Convictions under the tree by-laws are subject to hefty fines.
Toronto and Region Conservation Authority
In addition to the City by-laws, a permit may also be required from the Toronto and Region Conservation Authority (TRCA). TRCA is a provincial agency established to regulate the floodplains in its jurisdiction. Under Ontario Regulation 166/06 "Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation" TRCA regulates and may prohibit work taking place within valley and stream corridors, wetlands and associated areas of interference and the Lake Ontario waterfront.
