Before booking any Toronto tree service, confirm four things: an ISA Certified Arborist on staff, a valid WSIB clearance certificate, liability insurance of at least $2 million, and a written fixed-price scope of work. Without all four, you carry risks you may not realize exist. Tree work is one of the most dangerous trades in Ontario. When something goes wrong on an uninsured or unqualified job, the consequences land on the homeowner.
The ISA Certified Arborist designation is the professional standard for tree care in North America. Earning it requires documented field experience in arboriculture, a written examination covering tree biology, diagnosis, pruning standards, rigging and safety, and ongoing continuing education to maintain the credential. You can verify any arborist's certification number and good standing at the ISA website.
Not every crew member on a job site needs to hold the credential. Groundspeople and climbers work under the supervision of the arborist of record. What matters is that the company has at least one ISA Certified Arborist who plans the work, assesses the trees, and ensures everything is done to professional standards. If a company cannot name an ISA arborist or provide a certification number when asked, find another company.
The Workplace Safety and Insurance Board covers workers injured on the job in Ontario. If a tree service crew member is injured on your property and the company is not registered with WSIB, you as the property owner can be held financially liable for the costs. This is not a hypothetical. It happens to Toronto homeowners every year.
Request a WSIB clearance certificate before signing anything. The company can pull one from the WSIB website in under two minutes. A legitimate company has it ready. A company that pushes back, makes excuses, or promises to send it later is telling you something you need to hear before you hire them.
Ask for proof of commercial general liability insurance with a minimum $2 million per occurrence. This covers damage to your property and adjacent properties during the work: branch falls, vehicle damage, fence and structure impacts, and anything else that goes wrong. A company working on your property without adequate insurance means any damage comes out of your own home insurance policy and your deductible.
Ask for the actual certificate of insurance, not just a verbal assurance. The certificate names the insured, the insurer, the policy number, the coverage amount, and the expiry date. Check that it is current. Some companies carry minimum coverage that lapses between renewal dates.
What to confirm before booking any Toronto tree service:
A written quote from a professional tree service specifies the species and approximate size of each tree being worked on, the exact scope (full removal, crown pruning, deadwood removal, with or without stump grinding), what debris and cleanup is included, access provisions, whether permit work is included in the quote price or billed separately, and a fixed total. Vague quotes that say tree removal for $X without specifying what the X covers are not quotes. They are starting points for disputes.
Get at least two written quotes for any job over $1,500. The comparison is valuable not just for price but for scope. If one company is proposing something meaningfully different from another, you need to understand why. Sometimes the cheaper quote is cheaper because it excludes stump grinding, debris haul-away, or permit work that the higher quote includes. Sometimes it is cheaper because the company does not carry adequate insurance.
Topping is the practice of cutting the tops of trees at an arbitrary height rather than making proper pruning cuts at branch unions. It is recognized by the ISA and every credible arboricultural body as harmful, unprofessional practice. It creates large wounds that do not close properly, leads to weak water sprout regrowth, and ultimately accelerates the decline of the tree. If a company recommends topping, stop the conversation and find someone else.
Door-to-door solicitation after a storm is a pattern associated with storm chasers: transient operators who move into an area after weather events, offer discounted prices, take a deposit, do poor work, and may disappear before completing the job. A company showing up at your door the day after a storm is not a company you know anything about. Take the time to verify credentials before agreeing to anything.
Pressure to sign quickly, same-day offers that expire, or reluctance to put anything in writing are all signals that a company is managing your decision rather than serving your interest. A legitimate tree service is comfortable with you taking a day to review a written quote and make a considered decision.
If the tree you want removed or significantly pruned measures 30cm DBH or more on private property in Toronto, a Chapter 813 permit is required. A qualified tree service identifies this at the time of assessment. A company that assures you no permit is needed without measuring the tree, or that suggests working around the permit requirement to save time, is not giving you sound advice and is potentially exposing you to fines that can reach $100,000 per tree.
Ask specifically whether the quote includes the permit arborist report and application management, or whether that is extra. Some companies handle permits as part of their full-service offering. Others quote the removal only and leave the permit process to the owner. Either model is fine, as long as the expectation is clear in writing from the start. For full details on the permit process, see our Toronto tree removal permit guide.

A professional crew arrives on time with a clearly marked truck, sets up visible work zone markers, and walks you through the day's plan before any cutting begins. The arborist confirms the scope, identifies the drop zone, and checks for underground utilities, nearby structures, or any site conditions that need specific management. Work proceeds in a coordinated way with clear communication between the climber and the ground crew.
Cleanup is part of the service. All wood, brush, and chips leave the site. The stump is at the agreed height or ground to below grade if that was in the scope. Before the crew leaves, someone walks the work area with you to confirm the job is complete to your satisfaction. If you are not happy with something, raise it before the truck leaves.
Does a tree service in Toronto need to be licensed?
Ontario does not have a provincial tree service license. The most important credential is the ISA Certified Arborist designation, which requires documented field experience, a written examination, and ongoing education. Always verify the arborist's ISA number at isa-arbor.com and ask for a WSIB clearance certificate and proof of liability insurance before any work begins.
What should a written tree removal quote include?
A proper written quote should specify: the species and approximate size of each tree, the exact scope (full removal, pruning, with or without stump grinding), what debris removal and cleanup is included, access requirements, whether permit work is included or excluded, and a fixed total price. Avoid any quote given verbally only or one that is vague about what is and is not covered.
Someone knocked on my door offering cheap tree work. Is this a red flag?
Yes, treat it with caution. Legitimate tree services rarely solicit door to door. Unsolicited offers after storms are a pattern associated with uninsured contractors who take deposits, do poor quality work, and may leave before the job is complete. Ask immediately for their WSIB clearance certificate number and insurance certificate. If they cannot provide either on the spot, do not hire them.
How much should tree removal cost in Toronto in 2026?
Most residential tree removals in Toronto cost between $800 and $3,500 depending on tree size, location, access constraints, and whether stump grinding is included. Very large trees in tight spaces with difficult access can exceed $5,000. A quote significantly below this range from an unknown company is a signal to ask hard questions about insurance and qualifications before signing anything.
