What is an arborist report?
An arborist report describes in detail the physical attributes of one or more trees on a property. Information required in an arborist report includes the location, size, condition, structural integrity and vigour of a tree, as well as the presence of any diseases and/or infestations by pests.
In general, an arborist report will document the overall health of a tree and recommend ways to best preserve it during construction activities or, conversely, provide evidence to justify its removal.
Types of arborist reports available in Toronto
Arborist reports can be divided into two streams: construction related, and non-construction related.
Non-construction related arborist reports are typically used to support the injury or removal of a protected tree. A homeowner may wish to remove a tree that is structurally unsound, hazardous, messy, or that is interfering with an existing building or deck.
Construction related arborist reports are used to both recommend ways to protect desirable trees on a property, and also support the removal of trees during construction activities. The goal of a construction related arborist report is to balance tree preservation and homeowner satisfaction in accordance with current Toronto Forestry Guidelines. Construction related arborist reports are more detailed than non-construction arborist reports.
The cost of an arborist report in Toronto depends on the scope of the project.

An arborist report should be completed by an arborist certified through the International Society of Arboriculture (ISA Certified Arborist), or through the Ontario College of Trades.

When is an arborist report needed?
Within the GTA, certain trees are protected under the Tree Protection By-law, including:
- Street trees of any size
- Private trees with a diameter of 30cm or more at 1.4m from the ground
- Any vegetation and any tree located in an area regulated under Ravine and Natural Feature Protection By-law
A permit from Toronto Forestry is needed for any activity that could result in injury or removal of a protected tree. An arborist report is a required part of the permit application.
