You can cut down most trees in your Toronto backyard without a permit if the trunk diameter is under 30 centimeters (measured at 1.4 meters height), but larger trees require City of Toronto approval, and dead or hazardous trees have special exemptions. Quick answer: Trees under 30cm diameter don’t need permits; trees 30cm+ require permits ($75-$399) and arborist reports unless they’re dead or pose immediate danger—though you must document emergencies and notify the city within 7 days.
The Quick Answer: Can I Cut Down a Tree in My Toronto Backyard?
Toronto’s tree protection bylaw (Chapter 813) regulates all tree removal on private property, including backyards. You need a permit to remove any tree with a trunk diameter of 30 centimeters or more (about 12 inches), measured at 1.4 meters (roughly chest height) above ground. Smaller trees can be removed without permits. However, even for large trees, you don’t need a permit if the tree is dead, structurally unsound to the point of being dangerous, or invasive species specifically listed in the bylaw—though you must be able to prove this with professional documentation if the city investigates.
Backyard removal costs $800-$3,000 typically, with the higher end reflecting difficult access (narrow side yards, fenced areas requiring hand-carry equipment). Add $75-$399 for permits and $300-$600 for arborist reports if required.
When Do You Need a Permit to Remove a Backyard Tree in Toronto?
Toronto’s permit requirement is straightforward: diameter is the only measurement that matters. Height, species, tree health, and location on your property are irrelevant to the basic permit question—only diameter counts.
Measure your tree correctly:
- Measure 1.4 meters (about 4.5 feet) up from ground level—this is “breast height” in forestry terms
- Measure straight across the trunk at this height (the diameter, not circumference)
- If the trunk forks below 1.4 meters, measure the largest stem above the fork
- If multiple stems emerge from ground level, measure the largest single stem
Under 30cm? No permit needed. Over 30cm? Permit required.
One critical exception: If your backyard tree is in a ravine, on a steep slope (15% grade or more), or within 10 meters of a watercourse, additional environmental protections may apply even if the tree is under 30cm. These areas often require Toronto Region Conservation Authority (TRCA) permits in addition to city permits. This is common in neighbourhoods like:
- Scarborough: Ravine systems (Highland Creek, Rouge River, Morningside Park areas)
- Etobicoke: Humber River valley, Mimico Creek areas
- North York: Don River valley tributaries
- East York: Taylor Creek, Warden Woods ravines

What Are the Exemptions for Backyard Tree Removal in Toronto?
Even if your tree exceeds 30cm diameter, you can remove it without a permit in these specific situations:
Dead Trees
A tree is considered dead if it has no living cambium (the layer between bark and wood), no buds or leaves during growing season, and brittle, dry branches throughout the canopy. However, you must be able to prove the tree was dead if questioned. The city may investigate based on neighbour complaints or random inspections, and if you can’t provide an arborist letter confirming the tree was dead at time of removal, you’ll face fines ($500 minimum for individuals, up to $100,000 for corporations).
Best practice: Get an arborist assessment before removal, stating in writing that the tree is dead. This documentation protects you completely. Many Toronto tree services, including ours, provide written hazard assessments specifically for this purpose.
Structurally Unsound or Hazardous Trees
Trees with major structural defects that pose “imminent risk” to people or property can be removed without permits. Qualifying defects include:
- Trunk cracks extending more than halfway through the diameter
- Significant lean (more than 15 degrees) toward structures or high-traffic areas
- Root failure with visible soil heaving or tilting
- Extensive decay (more than 30% of trunk circumference hollow or rotten)
- Broken or hanging branches over structures, driveways, or walkways that can’t be safely pruned
Critical requirement: You must have a certified arborist document the hazard in writing before removal. After removal, you must submit this documentation to the city within 7 days. Failure to do so can result in fines even if the tree genuinely was hazardous.
The arborist report should include photos, measurements, a description of the structural defect, and professional opinion that removal was necessary for safety. This isn’t a full permit-application arborist report (which costs $300-$600)—a shorter hazard assessment letter (typically $150-$300) is sufficient for emergency exemptions.
Specific Invasive Species
Toronto’s bylaw lists certain invasive species that can be removed without permits regardless of size. However, the list is very short and doesn’t include most trees homeowners want to remove. Check the current bylaw or consult an arborist if you think your tree qualifies—don’t assume common “nuisance” trees like silver maples or Manitoba maples are on the exemption list (they’re not).
How Much Does Backyard Tree Removal Cost in Toronto?
Backyard trees cost 30-50% more to remove than equivalent front-yard trees due to access challenges. Most Toronto residential lots have 3-4 foot side yards and fenced backyards, meaning crews can’t bring bucket trucks, chippers, or log haulers to the work site. Instead, they must:
- Hand-carry all equipment (chainsaws, ropes, rigging gear, ladders)
- Climb and rig every branch for controlled lowering (can’t simply drop them)
- Cut wood into smaller sections (can’t use log trucks for large trunk sections)
- Haul all brush and wood through narrow side yards to trucks on the street
This manual work adds significant labor time and crew size requirements.
| Tree Size | Front Yard (Easy Access) | Backyard (Difficult Access) | Typical Backyard Premium |
|---|---|---|---|
| Small (under 30 ft) | $500 – $700 | $700 – $1,000 | +$200 – $300 |
| Medium (30-60 ft) | $900 – $1,400 | $1,200 – $2,000 | +$300 – $600 |
| Large (60-80 ft) | $1,800 – $2,800 | $2,400 – $3,800 | +$600 – $1,000 |
The premium is highest for medium-to-large trees where the difference between crane/bucket work and manual rigging is most pronounced. Very small trees (under 20 feet) have minimal access premiums because they can be climbed and lowered easily even without heavy equipment.
Additional costs for backyard trees:
- Stump grinding: $250-$500 (backyard stumps often require smaller, slower grinders that fit through narrow gates)
- Permit fees: $75-$399 depending on tree diameter
- Arborist report: $300-$600 if required for permit
- Fence removal/reinstallation: $200-$400 if gates are too narrow for equipment
Can You Cut Down Your Own Backyard Tree, or Do You Need Professionals?
DIY tree removal is legal in Toronto for trees on your own property (assuming permits are obtained if required), but it’s almost never advisable for trees over 15 feet tall or 6 inches diameter. Tree work is one of the most dangerous activities homeowners attempt—chainsaw injuries, falls from ladders, and struck-by-falling-branch accidents send hundreds of Ontarians to emergency rooms annually.
When DIY Might Be Appropriate
Consider DIY only for trees that meet ALL these criteria:
- Under 15 feet tall and under 6 inches diameter (smaller than a typical ornamental cherry or crabapple)
- Not leaning significantly (less than 5 degrees from vertical)
- Located at least 20 feet from all structures, power lines, fences, and property lines
- Healthy wood structure (no decay, no dead branches)
- You have experience with chainsaws, proper safety gear (chaps, helmet, eye protection), and a clear understanding of felling direction and escape routes
Even then, homeowner’s insurance may not cover injuries or property damage resulting from DIY tree work—check your policy before attempting removal.
Why Backyard Trees Are Especially Risky for DIY
Backyards compound risk factors:
- Limited drop zones: Most backyard trees can’t be felled in one cut because they’d hit fences, sheds, gardens, or neighbouring properties. This requires climbing and piece-by-piece removal—far more dangerous.
- Power lines: Many Toronto backyards have overhead utility lines. Any contact with power lines can be fatal. If branches are within 3 meters, only licensed utility arborists can work near them.
- Property line disputes: Backyard trees are often near lot lines. If your tree (or debris) damages a neighbour’s property during DIY removal, you’re liable—professional tree services carry $2M+ liability insurance for exactly this reason.
- No escape routes: Fences, sheds, and gardens limit your ability to quickly move away if the tree falls unpredictably—a leading cause of fatalities in tree work.
Professional removal for a typical backyard tree costs $1,200-$2,000. Emergency room visits, property damage repairs, and lost work time from injuries can easily exceed $10,000. The math is clear.
“I thought I could save money by cutting down a 40-foot ash in my Etobicoke backyard myself. Got halfway through the trunk cut when I realized it was leaning the wrong way toward my garage. Called Toronto Tree Removal in a panic. They came out same-day, safely finished the removal, and didn’t even make me feel stupid about the situation—though I definitely learned my lesson. The $1,400 I paid them was a bargain compared to what could’ve happened.” — Robert T., Etobicoke
What About Trees on Property Lines Between You and Your Neighbour?
Trees whose trunks straddle property lines are legally owned by both property owners equally under Ontario law. You cannot remove a boundary tree without your neighbour’s written consent, even if 90% of the tree is on your side—if any part of the trunk crosses the property line at ground level, it’s a shared tree.
Removing a boundary tree without neighbour consent can result in:
- Civil lawsuits for the value of the tree (which can be $5,000-$50,000+ for mature trees based on appraisal methods)
- City of Toronto fines for bylaw violations
- Court orders requiring you to plant replacement trees
- Damaged neighbour relations (obviously)
If you and your neighbour both want the tree removed:
- Get written agreement from both parties
- Determine who will pay (often split 50/50, but sometimes based on who benefits more from removal)
- One property owner applies for the permit (both can be listed as applicants)
- Both property owners should be present or provide written authorization when work is done
If your neighbour’s tree is dropping branches into your yard: You can prune branches that overhang your property line, up to the property line, without your neighbour’s permission—but you can’t cross the property line to do it, and you can’t damage the tree’s health. If pruning would harm the tree (e.g., removing more than 30% of canopy), you may need to negotiate with your neighbour or seek mediation.
Boundary tree disputes are common in Toronto, especially in older neighbourhoods (The Beaches, Leslieville, High Park, Rosedale) with mature trees and close lot lines. If you’re in this situation, consulting an arborist who can provide neutral assessment and documentation often helps facilitate neighbour agreements.
How Long Does the Toronto Backyard Tree Removal Permit Process Take?
Expect 6-10 weeks from application submission to permit approval for backyard trees, slightly longer than front yard trees because site inspections are required (city inspectors need to access backyards to verify tree measurements and health). The process includes:
- Pre-application (1-2 weeks): Hire an arborist to assess the tree and prepare a formal report (required for most permits). The arborist measures the tree, documents its health, explains why removal is requested, and provides professional opinion on alternatives.
- Application submission (1-3 days): Submit online or in-person at city offices, including the arborist report, site plan showing tree location, photos, and permit fee ($75-$399 based on tree diameter).
- City review and site inspection (3-6 weeks): City arborists review your application, may visit your property to verify details (backyard trees always require site visits), and assess whether removal is justified.
- Decision (1-2 weeks): Approval, denial, or conditional approval (e.g., “approved but you must plant two replacement trees”).
- Work window (within 18 months): Once approved, you have 18 months to complete removal. After removal, the city may inspect to verify compliance with conditions.
Denials are common for healthy trees without compelling reasons. “I don’t like it” or “it drops leaves in my pool” won’t get permits approved. Valid reasons include: structural hazards, disease/pest infestation that treatment can’t resolve, confirmed foundation or infrastructure damage, or construction conflicts (though you may be required to alter construction plans instead).
If denied, you can appeal to the city’s Tree Appeal Panel, but success rates are low unless you provide new evidence not included in the original application.

Neighbourhoods Where Backyard Tree Removal Is Most Common
Scarborough: Mature 1960s-70s subdivisions with aging silver maples, ashes heavily impacted by emerald ash borer. Narrow side yards typical—expect higher costs for access challenges.
Etobicoke: Mix of older homes with large backyard trees (often too close to structures by modern standards) and newer subdivisions. Lake-effect winds cause significant storm damage, making dead branch removal common.
North York: Dense urban forest, many backyard trees near power lines. Permit denials more common here due to city’s emphasis on canopy preservation.
Vaughan: Newer homes often have builder-planted trees in backyards that grow too large for the space within 10-15 years (Bradford pears, fast-growing maples). Also issues with trees too close to pools or decks.
Mississauga: Similar to Toronto in requirements and costs. Heavy ash tree losses creating backyard gaps homeowners want to fill with different species.
Markham: Newer subdivisions with small lots—backyard trees quickly outgrow spaces. Also significant road salt damage on properties backing onto major roads.
The Beaches, Leslieville, Riverdale: Older neighbourhoods with mature backyard trees, often on narrow lots with challenging access. Boundary tree disputes common due to close property lines.
Frequently Asked Questions: Backyard Tree Cutting Toronto
Can I remove a tree in my backyard if it’s damaging my foundation?
Yes, but you need documentation. Hire a structural engineer to assess and confirm foundation damage, and an arborist to confirm the tree is the cause (root systems visible in cracks, timing of damage correlates with tree growth, etc.). Submit both reports with your permit application—the city will typically approve removal for confirmed structural damage. However, you may be required to plant replacement trees elsewhere on your property. Foundation repair costs $5,000-$30,000+, so the $500 for professional assessments is worthwhile to ensure you’re addressing the actual cause.
What if my backyard tree is dropping branches on my house?
Occasional small branch or twig drop is normal and doesn’t justify removal permits. However, if the tree is dropping large branches (over 2 inches diameter) or showing signs of structural failure (dead limbs, cracks, decay), document it with photos and dates, and have an arborist assess whether the tree is hazardous. If confirmed hazardous, you can remove it without a permit under the emergency exemption—but you must provide arborist documentation to the city within 7 days. If the tree is healthy but just large and overhanging, the city will likely recommend pruning instead of removal, which doesn’t require permits as long as you remove less than 30% of the canopy.
Do I need my neighbour’s permission to remove my own backyard tree?
Only if the trunk crosses the property line at ground level—then it’s a boundary tree requiring joint consent. If the tree is entirely on your property (even if branches overhang the neighbour’s yard), you don’t need their permission for removal. However, it’s good practice to notify neighbours before removal work, especially for large trees that might drop debris into their yard during the process. Professional tree services typically notify adjacent properties as a courtesy.
Can I just cut my backyard tree down and claim it was dead if someone asks?
No. This is illegal and the city investigates complaints regularly. Penalties for removing protected trees without permits include fines starting at $500 for first offenses and up to $100,000 for repeat offenses or particularly valuable trees. The city can also issue stop-work orders, require you to plant replacement trees (at your expense), and pursue civil penalties for lost urban canopy value. If a tree removal company agrees to remove a protected tree without proper permits or documentation, they’re operating illegally—legitimate companies will refuse these jobs to protect their licenses and insurance.
How much does it cost to remove a 50-foot tree from my backyard in Toronto?
A 50-foot backyard tree in Toronto typically costs $1,400-$2,200 to remove, depending on access (narrow side yard vs. wide gate or removable fence section), proximity to structures (requires careful rigging), and species (oak and walnut are denser and harder to cut than maple or ash). Add $300-$450 for stump grinding, $150 permit fee (50-foot trees are usually 30-60cm diameter range), and potentially $300-$500 for an arborist report if needed for the permit. Total project cost: $2,300-$3,600 for a typical scenario. Emergency same-day removal adds 50-100% to base costs.
