What Is an Arborist Report
An arborist report is a professional written assessment of one or more trees on a property. It documents tree health, structure, risk, and clear recommendations. Think of it like a “report card” for your trees, except the teacher is wearing a hard hat and measuring tape.
These reports are commonly used for city permit applications, construction and development planning, insurance documentation, and tree preservation decisions. The consulting arborists we connect you with prepare reports aligned with common municipal expectations and industry best practices, including guidance and frameworks published by the International Society of Arboriculture (ISA).
When You May Need an Arborist Report in Toronto
- Tree removal permits and protected tree bylaws
- Development, additions, or projects near trees (driveways, pools, underpinning, basements, additions)
- Tree risk and safety concerns (leaning trees, cracks, decay, storm damage)
- Insurance documentation after a tree failure or impact
- Neighbour or property disputes (boundary trees, alleged damage, shared responsibility)
- Tree preservation, mitigation, and replacement planning
Types of Arborist Reports and Inspections We Can Help With
Not all “arborist reports” are the same. Toronto and GTA projects often need a specific format or scope depending on the reason you need documentation. Below are the common report types we can match you with.
1) Arborist Inspections and Tree Reports
This is the general category most people mean when they say “arborist report.” It typically includes tree identification (species), measurements (like diameter at breast height), health and structural observations, target assessment (what could get hit), photos when required, and professional recommendations.
2) ISA Tree Risk Assessments (TRAQ-style approach)
When safety is the concern, arborists often use a structured approach that considers likelihood of failure, likelihood of impact, and consequences. The goal is simple: replace guesswork with a defendable plan (prune, reduce weight, monitor, cable/brace, or remove when necessary). This can be especially useful after storms, when a tree “looks fine” but has hidden defects that love surprises.
3) Tree Appraisal Reports
A tree appraisal estimates the value of a tree. This can be useful for insurance, disputes, or documenting tree value before and after damage. Appraisals can consider factors like species, size, condition, and contribution to the site. If you are dealing with a claim or conflict, having a professional valuation can turn a loud argument into a document everyone can actually read.
4) Butternut Health Expert Reports (when required)
Some sites involve regulated or protected species considerations. Butternut trees can require specialized assessment depending on project context and applicable rules. If your project or permit process calls for a butternut-focused evaluation, we can connect you with the appropriate qualified professional to assess health indicators and provide supporting documentation.
5) Remedial Work Reports for an Order to Comply
If you have received an Order to Comply or a notice that a tree condition must be addressed, a consulting arborist can document current conditions and outline practical remedial steps. This may include pruning specifications, risk reduction steps, monitoring schedules, or other mitigation options designed to satisfy compliance expectations without overdoing it.
6) Exploratory Dig and Exploratory Root Excavation
Roots are where many projects go sideways. Exploratory root excavation can help confirm root location, depth, conflicts with construction, and the real story behind heaving walkways or foundation concerns. This kind of assessment is often used to support development planning, engineering coordination, and tree protection strategies.
7) Tree Protection Plans, Tree Preservation Plans, and Tree Protection Fencing
If you are building near trees, documentation often needs to address how trees will be protected during construction. A consulting arborist can outline tree protection zones, fencing requirements, access routes, material storage rules, and mitigation steps. For Toronto-area projects, this is often paired with clear site notes so contractors do not “accidentally” park a skid steer on a root zone.

Our Arborist Report Process
Step 1) Confirm what you actually need
Permits, insurance, safety concerns, development, compliance, appraisal, or preservation planning all have different documentation needs. We start by identifying the purpose so you do not pay for the wrong report (or submit the right report in the wrong format).
Step 2) Site visit and assessment
The consulting arborist visits the property to inspect tree health, structure, defects, and site context. They note targets like buildings, fences, driveways, sidewalks, and overhead utilities. Measurements, photos, and tree IDs are gathered as required.
Step 3) Report preparation
You receive a clear written report suitable for the intended use. Depending on scope, it may include an inventory table, risk ratings, recommendations, and supporting photos or sketches.
Step 4) Next steps support
If the report recommends follow-up actions (pruning, removal, preservation fencing, monitoring), you can use it to plan next steps. If storm damage is involved, you may also want:

Toronto Permits and Tree Bylaws (Helpful Resources)
Tree rules vary by municipality and tree size. If you are working in Toronto, review official guidance here:
City of Toronto Tree Protection. For broader provincial information, see:
Ontario Trees and Forests. For industry standards and education resources:
International Society of Arboriculture (ISA).
How Much Does an Arborist Report Cost
Pricing depends on the scope. A single-tree risk assessment is different from a full site inventory or a protection plan supporting construction. Common factors include number of trees, site complexity, access, required drawings/tables, municipality expectations, and turnaround time.
Tip: If your project involves multiple report needs (example: inventory + protection fencing + risk notes), bundling scopes can be more efficient than ordering everything separately.

Frequently Asked Questions
What does Toronto usually want to see in an arborist report
Most permit or planning contexts expect clear tree identification, measurements, condition notes, risk considerations (where relevant), and specific recommendations. If a protection plan is needed, clear protection zones and fencing notes are often required.
How do arborists measure a tree
A common measurement is diameter at breast height (DBH), taken around 1.4 m above ground. This is used in many bylaws and planning documents, alongside species and condition notes.
Can a report help me avoid removing a tree
Yes. Many reports recommend mitigation like pruning, weight reduction, structural support (where appropriate), or monitoring rather than removal. The goal is safety and practicality, not “cut everything down and call it a day.”
Do you offer tree appraisal for insurance or disputes
Yes, we can connect you with professionals who prepare tree appraisal documentation when valuation is required for claims, disputes, or property documentation.
What is exploratory root excavation and why would I do it
It helps confirm where roots actually are, which can be crucial before digging, building, or diagnosing root-related damage. It can also support tree protection planning and reduce construction surprises.
How fast can I get an arborist report
Turnaround depends on scope and season. Single-tree assessments can sometimes be scheduled quickly, while multi-tree inventories and construction-related documents may take longer due to formatting and coordination needs.
