Call 311 or dial 647-558-1366 for a private ISA-certified arborist if the city’s queue is too slow. Toronto manages over 600,000 street trees and handles thousands of tree-related service requests every year — but knowing which requests go to 311, which go to Urban Forestry directly, and which require a licensed arborist on your own dime is the question that stumps most GTA homeowners. This guide untangles it all.
The 60-Second Decision: 311, Private Arborist, or Toronto Hydro?
Before anything else, use this routing guide. Pick the situation that matches yours and go straight to the right contact — don’t waste time filing a 311 request for something the city won’t act on.

| City tree needs pruning (non-urgent) | 311 — Routine Request | 311 or online SR form |
| Private tree (on your property) fallen or hazardous | Private ISA-certified arborist | 647-558-1366 |
| Private tree ≥30 cm DBH you want to remove | Chapter 813 permit first, then private arborist | toronto.ca/trees + 647-558-1366 |
| Tree touching or near hydro lines | Toronto Hydro | 416-542-8000 (press 1) |
| Neighbour’s tree threatening your property | Neighbour first; 311 as last resort; lawyer for damage claims | 311 → 647-558-1366 for arborist report |
| Tree blocking Bell/Rogers cable lines | Bell or Rogers (call each carrier) | Bell: 1-866-310-2355 |
| You want to plant a tree on city boulevard | 311 — Tree Planting Request | 311 or toronto.ca/trees/planting |

All 311 Tree-Related Service Request Categories
When you call 311 or visit toronto.ca/311 and navigate to Trees, Grass, Leaves & Weeds, you’ll find these service request types. Knowing the exact category gets your request routed faster and avoids redirection loops.
SR Category 1 — City Street Tree or Park Tree Maintenance
Use this for a city-owned tree (on the boulevard between road and your property line, or inside a park) that needs pruning, inspection, or non-emergency care. The City’s Area Street Tree Maintenance (ASTM) program cycles through neighbourhoods roughly every 7 years. If your street is between cycles and the tree is genuinely concerning, a 311 request jumps it to the inspection queue. Service standard: inspection within 5–10 business days for non-hazardous requests.
SR Category 2 — Emergency Tree Clean-Up (Storm Damage)
A city-owned tree that has fallen, is blocking traffic, or poses an immediate hazard to pedestrians gets priority routing — service standard for imminent hazards is a maximum of 3 days, though in a major storm event (like an ice storm or derecho), that can stretch. Submit online at: Emergency Tree Clean-Up SR. You’ll receive an SR number for tracking.
SR Category 3 — Dangerous Private Tree Complaint
If your neighbour’s tree is rotting, leaning, or has hanging dead limbs that threaten your property, and the neighbour won’t act, 311 can trigger a City inspection. Important: the City treats this as a last resort. City staff will issue an Order to Comply if the tree is confirmed as an immediate danger — but they won’t do the work themselves. The property owner bears the cost. For this SR, expect a response in 5 business days. Use the SR linked to “Dangerous Private Tree” in the 311 portal.
SR Category 4 — Tree Ownership Enquiry
Not sure if that street tree is yours or the city’s? Call 311. They’ll cross-reference your address against City property data maps. If the base of the tree trunk is more than 50% on the City road allowance, it’s a City tree — their problem. More than 50% on your side of the property line? It’s yours. Boundary cases require a certified survey.
SR Category 5 — Request to Remove a City Tree (Application to Injure or Destroy)
If you want a healthy city tree removed — say it’s heaving your driveway or blocking your solar panels — you can submit an Application to Injure or Destroy Trees. Be prepared: the City will deny removal if it doesn’t meet by-law criteria. There are fees for the application. The City only removes trees when they are dead, structurally hazardous, or no longer viable to maintain safely.
SR Category 6 — Request for Tree Planting (Boulevard)
Want a new tree on the public boulevard in front of your home? 311 routes this to the Tree Planting program. Toronto’s goal is to reach 40% tree canopy cover by 2050 (currently at 28%). Planting requests are reviewed against available species lists and site conditions. No charge to the homeowner.
SR Category 7 — Asian Long-Horned Beetle / Invasive Species Report
Spotted D-shaped exit holes, sawdust frass, or oozing sap on a maple, horse chestnut, or elm? Report it immediately through 311. ALB is a federally regulated pest — infected wood cannot be moved off-site via regular waste. Call 311 for disposal instructions specific to your situation.
How to Report a Fallen Tree in Toronto: Step-by-Step
A fallen tree in Toronto is one of the most common 311 calls. Here’s the exact process so you don’t waste time:
- Determine ownership. Is the tree’s trunk base on the City road allowance (boulevard) or on private property? City road allowances run from the curb to the property line — typically 3–7 metres, but it varies by street.
- Assess the hazard level. Is it blocking a sidewalk, road, or driveway? Is anyone injured? Are there electrical wires involved?
- City tree — call 311 immediately (24 hours a day, 7 days a week). Select “Emergency Tree Clean-Up.” Provide your exact address, the direction the tree fell, and whether any wires are involved. You’ll get an SR number.
- Private tree — call a licensed arborist. If the fallen tree is on your property, the City will not respond. You need a private ISA-certified arborist. We respond to storm emergencies across Toronto, Scarborough, North York, Etobicoke, Vaughan, Mississauga, Markham, and Brampton within 2 hours. Call 647-558-1366.
- Document everything. Take photos immediately — for insurance claims, Chapter 813 imminent-hazard exemptions, and any future liability dispute with a neighbour.
- If a City tree damaged your property, contact 311, then file a claim with the City. The City is not automatically liable — contact your insurer first.
“After the ice storm in February 2026, a 70-foot silver maple split across my Scarborough driveway at 2 a.m. Toronto Tree Removal Ninja had a crew there by 4:30 a.m. — cleared the driveway, stump-ground on the spot, and gave me a written arborist report for my insurance claim. Total cost was $2,400 CAD and every dollar was worth it.” — David M., Scarborough, February 2026
Who Owns That Tree? Understanding City vs. Private Responsibility
This is the single most common point of confusion for Toronto homeowners. The rule is simple once you know it:
- City-owned tree: Trunk base is located in the public road allowance (between curb and property line) OR in a City park. City maintains it, City pays for it.
- Private tree: Trunk base is on your lot. You own it, you maintain it, you pay for removal if needed.
- Boundary tree: Base straddles the property line. If more than 50% of the base is on City property → City’s responsibility. More than 50% on your side → yours. Dispute? You may need a certified property survey.
As of 2026, Toronto manages over 600,000 street trees plus hundreds of thousands more in parks. Urban Forestry inspects each one on a roughly 7-year cycle. If you’re unsure who owns a tree, call 311 and they’ll look it up.
Chapter 813 Permit Walk-Through: Removing a Private Tree in Toronto
Toronto Municipal Code Chapter 813 — the Private Tree By-law — protects any tree on private property with a trunk diameter of 30 centimetres or more, measured at 1.4 metres above grade (DBH). Remove or injure such a tree without a permit and you’re looking at fines from $500 to $100,000, plus mandatory replacement planting.
Step 1: Measure Your Tree
Wrap a tape measure around the trunk at 1.4 metres above ground. Divide the circumference by π (3.14159). If that number is 30 cm or above, you need a permit before any removal or significant injury. If it’s under 30 cm, no permit needed — but you must still follow good arboricultural practice.
Step 2: Determine if an Exemption Applies
There are limited exemptions under Chapter 813:
- Imminent hazard: If a certified arborist declares the tree an imminent hazard to persons or property, no permit is required — but you must photograph the tree, contact 311 to create a record, and retain the arborist’s written assessment.
- Dead tree: A tree confirmed dead by an ISA-certified arborist may be removed without a permit — again, retain documentation.
- Construction damage: If a permitted building project requires tree removal, it may be covered under the building permit’s Tree Protection Plan (TPP).
Step 3: Submit the Permit Application
Apply through the City’s Tree & Ravine Protection portal. You’ll need:
- Property address and contact information
- Tree species, DBH measurement, location on lot (photo or sketch)
- Reason for removal (hazard, construction, disease, etc.)
- If construction-related: an Arborist Report from an ISA-certified arborist
Application fee: approximately $256 CAD for a single-tree residential application (fees subject to change — confirm at toronto.ca at time of application).
Step 4: Wait for Approval
Standard processing: 5–10 business days for straightforward residential requests. More complex applications (development projects, ravine-adjacent properties, protected species) can take 4–8 weeks. Urban Forestry may require a site inspection before approving.
Step 5: Replacement Trees
Approved removal usually triggers a replacement planting requirement — typically 1–2 new trees, or a cash-in-lieu payment to the City’s tree fund if planting isn’t feasible on site. Our team handles replacement-tree compliance for residential homeowners across all GTA municipalities.
Ravine and Natural Feature Protection By-law
If your property is near or within a ravine, the Ravine and Natural Feature Protection By-law applies to all trees regardless of size. Permits are required even for small trees. Check your property using the City’s Ravine By-law map before doing anything.
Neighbourhood-by-Neighbourhood: City Tree Contacts Across the GTA
Toronto amalgamated in 1998, so a single 311 number handles the former City of Toronto, Scarborough, North York, Etobicoke, and York. For the surrounding 905 municipalities, you’ll need their own service lines for city-owned trees. Here’s the full breakdown for every area we serve:
Toronto (Core, East End, West End, Downtown)
- City-owned trees: 311 (24/7) or online SR portal
- Urban Forestry: Environment, Climate & Forestry division — toronto.ca/trees
- Permits: Tree & Ravine Protection — toronto.ca/building/tree-ravine
- Private trees: 647-558-1366 (we cover all Toronto neighbourhoods including Riverdale, The Beaches, Forest Hill, Rosedale, Cabbagetown, Parkdale, High Park, Etobicoke, East York)
Scarborough
- Scarborough is part of the City of Toronto — same 311 number and Urban Forestry division handle all city-owned trees.
- Scarborough neighbourhoods — Agincourt, Malvern, Rouge, Wexford, Birchcliffe-Cliffside — fall under the Toronto ASTM program’s east-district maintenance cycle.
- Private tree emergencies and permits in Scarborough: same Chapter 813 rules apply. Call 647-558-1366 for same-day service.
North York
- Also part of City of Toronto — 311 for city trees, Chapter 813 for private trees ≥30 cm DBH.
- North York includes Don Mills, Lawrence Park, Willowdale, Downsview, Bathurst Manor — all covered under Toronto’s street tree inventory.
- Notable: North York has significant silver maple and ash tree populations from 1960s–1980s plantings — many are now reaching end-of-life or require EAB assessment.
Etobicoke
- Part of City of Toronto — 311 applies. Etobicoke’s Humber Valley, Kingsway, and Islington neighbourhoods have mature tree cover with significant ravine-adjacent properties.
- If your Etobicoke property backs onto the Humber River valley or Black Creek, the Ravine By-law applies — all tree work needs review regardless of size.
- Private tree removal in Etobicoke: 647-558-1366.
Vaughan (York Region)
- City of Vaughan Public Works: 905-832-8585 or vaughan.ca/en/resident/parks-open-spaces
- Vaughan does not use 311 — report fallen city trees to Public Works directly.
- Vaughan’s Tree Protection By-law mirrors many Chapter 813 provisions — trees ≥15 cm DBH on private property may require a permit. Check at vaughan.ca.
- Private tree emergencies in Woodbridge, Maple, Kleinburg, Thornhill: 647-558-1366.
Mississauga (Peel Region)
- City of Mississauga 311 equivalent: 311 (within Mississauga boundaries) — routes to City of Mississauga, not Toronto.
- Mississauga Urban Forestry: 905-615-3200 or mississauga.ca/en/residents/parks
- Mississauga’s Tree Protection By-law covers trees with a trunk circumference of 71 cm or more (~22.6 cm DBH) on private property.

Brampton (Peel Region)
- City of Brampton Public Works & Engineering: 311 (Brampton has its own 311 service) or brampton.ca/trees
- Brampton’s Tree Preservation By-law applies to trees ≥30 cm DBH in designated areas and environmentally sensitive areas.
- Storm damage to city trees in Brampton: call 311 (Brampton routes to their Operations team).
- Private tree removal in Brampton (Heart Lake, Bramalea, Springdale, Castlemore): 647-558-1366.
Toronto Urban Forestry: Direct Contact Paths
Beyond 311, Urban Forestry (part of the City’s Environment, Climate & Forestry division) is the technical authority on all tree matters. Here’s how to reach the right person:
| Need | Contact Path |
|---|---|
| Private work on a City tree (hire your own contractor) | Email Karen.Sun@toronto.ca for “Application for Arborists Retained by Private Property Owners” |
| Tree permit application status | 311 (will route to Urban Forestry permit team) |
| Ravine protection question | toronto.ca/building/tree-ravine-protection-permits or 311 |
| Emergency City tree hazard | 311 24/7 — imminent hazard response standard: max 3 business days |
| Urban Forestry Grants & Incentives (private planting) | toronto.ca/environment/urban-forestry-grants |
| Asian Long-Horned Beetle or EAB report | 311 for ALB; CFIA (Canadian Food Inspection Agency) for formal pest reports: 1-800-442-2342 |
| Tree canopy complaint / unauthorized removal | 311 → Urban Forestry By-law Enforcement |
When 311 Won’t Help: The Private Arborist Case
The City of Toronto is explicit: “The City will not inspect private trees damaged by a storm. Maintenance of privately owned trees is the responsibility of the property owner.”
If you call 311 about a tree on your property, they will tell you to hire a private arborist. No matter how large or dangerous the tree is, the City’s crews will not come to your lot. That’s not a criticism — it’s just how municipal jurisdiction works. So the moment you’ve confirmed the fallen, leaning, or hazardous tree is on private land, you need a licensed arborist, not a 311 operator.
What a private ISA-certified arborist can do that 311 cannot:
- Respond within 2 hours for emergencies (our standard across the GTA)
- Provide a written hazard assessment that satisfies insurance companies and Chapter 813 imminent-hazard exemption requirements
- Remove and chip the tree on the same day — city crews often take weeks for non-emergency work
- Grind the stump and restore the site
- File the 311 imminent-hazard notification on your behalf to create the paper trail
- Advise on replacement-tree compliance to avoid by-law fines
Cost Reference: What Private Tree Work Costs in the GTA
| Tree Size | Typical Removal Cost (CAD) | Stump Grinding | Notes |
|---|---|---|---|
| Small (<10m / 30ft) | $600–$1,000 | $150–$250 | Most fruit trees, small ornamentals |
| Medium (10–20m / 30–65ft) | $1,000–$2,200 | $200–$400 | Common maples, ashes, pines |
| Large (20–25m / 65–80ft) | $2,200–$4,500 | $300–$600 | Mature silver maple, Norway maple |
| Very Large (>25m / 80ft+) | $4,500–$9,000+ | $500–$1,000 | Crane access often required |
| Emergency (storm, 24/7) | Add $400–$1,200 surcharge | Included in most cases | Hazard premium on after-hours calls |
| Arborist Report (permit/insurance) | $300–$600 | N/A | ISA-certified written assessment |
All prices are approximate as of 2026 and depend on access, species, lean direction, proximity to structures, and debris volume. Get a firm written quote before any work begins.
DIY vs. Hiring a Private Arborist
| Factor | DIY | ISA-Certified Arborist |
|---|---|---|
| Chapter 813 permit requirement | You still need the permit — no DIY exemption | Handles application, documentation, compliance |
| Tree ≥30 cm DBH | Not legal to remove without permit; fines $500–$100k | Files permit, confirms exemption if imminent hazard |
| Insurance documentation | DIY work generally not accepted by insurers | Written report accepted by TD, Intact, Aviva, etc. |
| Safety (power lines, rot, lean) | High fatality risk; chainsaw + falling tree + property | WSIB-covered, $5M liability, trained for hazards |
| Storm debris (branches <7.5 cm) | Bundle & curb — city collects for free | Full cleanup + chip included in quote |
| Small pruning (<30 cm DBH, good practice) | Legal — no permit needed | Recommended for structural work (ANSI A300 standard) |

Frequently Asked Questions
Does 311 handle fallen trees on private property in Toronto?
No. The City of Toronto is explicit: it does not inspect or maintain private trees damaged by storms. If the fallen tree is on your property — or came from your property — the cost and responsibility are yours. Call a licensed arborist. We respond across the GTA within 2 hours for emergencies: 647-558-1366.
How do I know if my tree needs a Chapter 813 permit before removal?
Measure the trunk diameter at 1.4 metres above ground (DBH). If it’s 30 cm or larger, you need a permit under Chapter 813 of the Toronto Municipal Code. Fines for unpermitted removal run $500 to $100,000. Two exemptions apply without a permit: (1) an ISA-certified arborist has declared the tree an imminent hazard, or (2) the tree is confirmed dead by an arborist — both require written documentation and a 311 notification.
How long does a tree removal permit take in Toronto?
Standard residential applications take 5–10 business days. Complex applications (construction projects, ravine-adjacent properties, heritage trees, large developments) can take 4–8 weeks. Submit early. If the tree becomes an imminent hazard while you’re waiting, the permit is no longer required — but get an arborist to document the hazard in writing before you act.
Who is responsible if a city tree falls on my house in Toronto?
The City of Toronto is not automatically liable. Liability depends on whether the City had prior notice of the hazard, whether it acted with reasonable care, and whether negligence can be proven. You should: (1) contact 311 immediately, (2) photograph everything, (3) file a claim with your own homeowner’s insurer right away, and (4) separately file a claim against the City if you believe they were negligent. Consult a lawyer for the City claim. We can provide an arborist report documenting tree condition for insurance or legal purposes.
Can I call 311 to report a dangerous tree on my neighbour’s property in Toronto?
Yes, but it’s a last resort. First, notify your neighbour in writing. If they don’t act and the tree poses an immediate danger to your property or safety, call 311 to request a “Dangerous Private Tree” inspection. City staff may issue an Order to Comply if the danger is confirmed. The City will not pay for or perform the removal — the tree owner bears that cost, typically $800–$3,500 CAD depending on tree size.
What are the 311 service codes for tree-related requests in Toronto?
Toronto 311 routes tree requests through the Trees, Grass, Leaves & Weeds category. The main service request types are: (1) City Street Tree/Park Tree Maintenance, (2) Emergency Tree Clean-Up (Storm Damage), (3) Dangerous Private Tree Complaint, (4) Tree Ownership Enquiry, (5) Application to Injure or Remove a City Tree, (6) Tree Planting Request, and (7) Invasive Pest/Species Report. Online SR forms are available at toronto.ca/311 under “Create a Service Request.”
How do I report a fallen tree blocking a Toronto road or sidewalk?
Call 311 immediately (24/7) or submit an online Emergency Tree Clean-Up request at toronto.ca/311. Provide your exact address, which direction the tree is blocking, whether power lines are involved, and whether there are injuries. You’ll receive an SR number. For City trees, the imminent-hazard response standard is a maximum of 3 days — though major storms cause delays. If the tree is on private property and blocking public access, still call 311 first; they’ll assess jurisdiction.
Do Vaughan, Mississauga, Markham, and Brampton use Toronto’s 311?
No. Toronto’s 311 only covers the City of Toronto (former municipalities of Toronto, North York, Scarborough, Etobicoke, York, and East York). For city-owned tree issues in Vaughan: call 905-832-8585. Mississauga has its own 311 that routes to their Operations team (905-615-3200 for Urban Forestry). Markham uses 905-477-5530. Brampton has its own 311 service. For private tree emergencies across all these municipalities, 647-558-1366 reaches us directly.
What size branches can I put on the curb for Toronto to pick up after a storm?
Branches from private trees can be left at the curb for regular waste collection if bundled to maximum 1.2 metres long × 0.5 metres wide, weighing under 20 kg. Any item over 7.5 cm (3 inches) in diameter needs a private contractor or arranged disposal. City crews will pick up debris from a City-owned tree they worked on — you don’t need to bundle that. Asian Long-Horned Beetle or other regulated pest wood: call 311 for specific disposal instructions before moving anything.
How does Toronto’s Area Street Tree Maintenance program work?
The ASTM program is Toronto’s shift from reactive to proactive street tree maintenance. Urban Forestry crews inspect and maintain all City-owned street trees in a designated area systematically — neighbourhood by neighbourhood — on a target cycle of once every 7 years. This means your street may not have had a proactive inspection in several years. If you see a concerning City tree before the crew gets to your area, submit a 311 service request — it gets the tree inspected outside the regular cycle.
