Maintenance of privately owned trees is the responsibility of the property owner. If you believe a tree or part of a tree, situated on a neighbouring property is at risk of falling, you should stay away from the area and immediately advise the property owner so that they may take the required action to address the situation. Contacting the City for inspection should be considered as a last resort to address hazardous situations.

Municipal Code Chapter 632, Property Vacant or Hazardous is intended to address hazardous situations where a property owner fails or refuses to eliminate a hazard. Chapter 632 enables City staff to investigate reported hazardous trees on private property and to issue orders for compliance where a hazardous situation has been identified. Contact 311 to submit a service request. Urban Forestry staff will investigate concerns of dangerous trees or branches on private property. Where staff confirm that a tree poses a danger to persons or property, the property owner and occupant will be advised and an Order to Comply to correct the contravention will be issued.

The City of Toronto does not regulate the trimming of trees on private property. Where a tree on private property is protected under provisions of the Private Tree Bylaw or Ravine and Natural Feature Protection Bylaw, pruning of the tree is permitted provided the pruning is in accordance with good arboricultural standards. Otherwise a permit would be required to injure or destroy the tree. A qualified tree expert should always be retained to carry out tree pruning.
