Hazardous or Dangerous Trees 

A tree is considered hazardous if all or part of the tree is in danger of falling and causing damage to property or injury to people. 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.

For private trees, an assessment needs to be done by a qualified arborist to determine if a tree is hazardous.

Maintenance or Removal of Fallen, Hazardous or Dangerous Trees  

Concerns about a City-owned tree that presents an immediate danger can be reported by contacting 311 to submit a Service Request. Reasons to report include:

  • If a tree or large tree branches have fallen or are posing a hazard or immediate danger.
  • If a tree or large tree branches have fallen on, are obstructing, or are posing a hazard or immediate danger to pedestrian or vehicular traffic.

For dangerous trees located on private property, the responsibility lies with the property owner. Concerns about a privately-owned tree that presents an immediate danger can be reported by contacting 311 to submit a Service Request. This will create a bylaw enforcement investigation by City staff.
