What construction supervision covers
Work near protected roots
We attend excavation, grading, demolition, and other approved work inside or beside a tree protection zone.
Permit condition review
We work from the approved arborist report, tree protection plan, and municipal conditions that apply to the activity.
On-site direction
The arborist can identify roots, direct approved tree-sensitive methods, and record conditions as the work proceeds.
Visit documentation
We document the work and findings required by the agreed scope. Municipal review and clearance remain the municipality's decision.

Coordinate milestone visits and recurring monitoring around the approved tree protection plan and construction schedule.
Excavation & demolition crews
Get tree-related direction on site while the approved work proceeds near protected trunks and roots.
This service is the right fit when:
- Your permit is issued and a city condition requires arborist inspections at defined construction milestones
- A city arborist has flagged potential non-compliance and you need a documented response
- You want independent confirmation that your contractor is keeping tree protection measures intact
- A storm or site incident damaged trees and you need a formal condition assessment on record
This is not what you need when:
- You are at the permit application stage and need a tree preservation and protection plan (see Construction Reports)
- You need a permit letter to remove a tree (see Tree Removal Reports)
- No construction is happening and you want a general tree health opinion with no municipal submission
Supervision starts at $145 per hour
Every booking has a three-hour minimum. We confirm the expected site time and documentation scope before approval.
Activity and work area
Send the excavation, demolition, grading, or root-work scope and its location relative to protected trees.
Approved documents
Include the arborist report, tree protection plan, permit conditions, and any municipal direction.
Site timing
Provide the requested start time, expected duration, and site contact who will meet the arborist.

Arborist Site Inspection FAQ
Common questions about site inspections for tree permits and construction projects
What is an arborist site inspection?
Arborist supervision is an on-site service for construction work near protected trees. An ISA Certified Arborist observes the approved work, directs tree-sensitive methods where required, and documents the visit for your project record or municipality.
When is arborist supervision required?
Your permit, arborist report, or municipal direction may require supervision during excavation, demolition, grading, root pruning, fencing changes, or other work inside a tree protection zone. Check the approved documents before scheduling trades.
What does an arborist site inspection include?
The scope can include review of approved documents, observation of the scheduled work, tree and barrier condition checks, photographs, arborist direction, and a written visit record. We confirm the required deliverables before the booking.
What does arborist supervision cost?
Construction supervision starts at $145 per hour with a three-hour minimum. We confirm the scope and quote before the visit.
Can you provide inspection reports during active construction?
Yes. We can attend a single construction activity or schedule visits at the milestones listed in your permit, arborist report, or tree protection plan.
What happens if issues are found during inspection?
We document the condition, explain the tree-related corrective work, and identify any municipal follow-up that may be required. If an order is already in place, use our Stop Work Order service.
Do you liaise with the municipality after the inspection?
Yes. We regularly communicate with municipal urban forestry departments across the GTA. We can submit inspection reports directly to the city, respond to city arborist queries, and provide supplementary information to support your project's permit compliance.
What municipalities do you serve?
We serve the entire Greater Toronto Area including Toronto, Mississauga, Oakville, Markham, Vaughan, Richmond Hill, Brampton, Burlington, Hamilton, Pickering, Caledon, King, Durham Region, and York Region.
