Property owners are responsible for maintaining their trees. If you notice a tree or branch on a neighbouring property that looks like it might fall, stay away, and tell the property owner right away so they can act. Contacting the City for inspection should only be a last resort.
Municipal Code Chapter 632, Property Vacant or Hazardous regulates trees that are an immediate danger to people or property. An immediate danger means a tree or branch is likely to fail within 30 days under normal weather conditions. Examples include large broken branches or trees that have uprooted or are leaning dangerously. The City can investigate hazardous trees on private property and issue orders to fix the danger.
To report a dangerous tree, contact 311. Urban Forestry staff will investigate your concerns. If they confirm a tree poses an immediate danger, they will notify the property owner and issue an Order to Comply.
Dead, diseased, or damaged trees may not be considered an immediate danger if they are not likely to fail soon. Smaller broken branches or slow developing issues typically do not pose an immediate risk. If a tree is not an immediate danger but still poses a longer-term risk, staff will refer it to Municipal Licensing and Standards under Municipal Code Chapter 629, Property Standards for further action.
The City of Toronto does not regulate tree trimming on private property. Where a tree on private property is protected by the City’s Tree By-laws pruning of the tree is permitted provided the pruning is completed in accordance with good arboricultural standards. Otherwise, a permit is needed to injure or remove the tree. It’s best to hire a qualified expert for any tree work.
