You spot a dead oak in your Toronto backyard — or notice a living maple leaning dangerously over your garage. Both need removal, but the paths are completely different. Dead trees require a standard permit under Chapter 813 (no exemption, no shortcuts). Hazardous living trees may qualify for emergency exemption if properly documented by an ISA-certified arborist. Here’s how to tell which situation you’re dealing with — and exactly what it costs in each case.
This is one of the most common permit misconceptions we see: homeowners assume a dead tree automatically skips the permit process. It doesn’t. And homeowners on the other side sometimes try to wait out a hazardous tree on the standard 30-business-day permit timeline, not realizing an exemption is available within 48–72 hours. Both mistakes cost time and money. Let’s fix that.
Hazardous Tree vs Dead Tree Removal: Quick Comparison Table
| Category | Dead Tree | Hazardous Living Tree |
|---|---|---|
| Definition | 100% no living cambium; no buds; dry, brittle branches throughout | Living tree showing structural defects: trunk cracks >50% diameter, lean >15°, imminent limb failure |
| Toronto Permit Required? | YES — Chapter 813 applies to any tree ≥30cm DBH regardless of health status | YES — standard permit required, but emergency exemption may be available |
| Emergency Exemption Available? | NO — dead trees do not qualify for exemption because there is no active, imminent hazard | YES — conditional exemption available with ISA-certified arborist documentation |
| Standard Permit Timeline | 30 business days (documentation of deadness may speed review 3–5 days) | 30 business days (or 48–72 hours via emergency exemption) |
| Permit Fee | $100–$300 depending on tree size | $0 if emergency exemption approved; $100–$300 for standard route |
| Assessment Report Cost | $300–$400 (dead-tree arborist letter) | $400–$600 (full hazard assessment) |
| Removal Cost | $1,200–$3,000 (size-dependent; decay adds unpredictability) | $1,500–$3,500 (high-risk rigging, emergency premium) |
| Typical Total Cost | $1,650–$3,400 | $1,900–$4,100 (or less with exemption bypassing permit fee) |
What Is a Dead Tree? (How to Tell & Why It Matters in Toronto)
A dead tree is one with zero living tissue — the cambium layer (just beneath the bark) is completely dry and brown, no buds are forming on any branch, and the wood has begun to dry and crack throughout. The key word is 100% dead. A tree dropping leaves in a dry summer, or one with partial dieback, is not legally dead under Toronto Urban Forestry standards.
How to confirm your tree is dead:
- Scratch test: Use a penknife or key to scrape a small patch of bark. Living trees show green or white cambium underneath. Dead trees show dry brown or grey tissue throughout.
- Branch flexibility: Snap a small twig. Living wood bends before breaking; dead wood snaps immediately with a dry crack.
- Bud check (spring/summer): No leaf buds forming anywhere on the tree — not on branches, not on the trunk — is a strong indicator of full death.
- Bark condition: Loose bark peeling in sheets without any green cambium beneath is a reliable dead-tree sign.
Why does the distinction matter in Toronto? Because many homeowners assume that a dead tree automatically skips the permit process under Chapter 813. This assumption is false and expensive. A $500+ fine is the minimum consequence for removing a protected dead tree without a permit.

What Is a Hazardous Tree? (Living Tree Posing Immediate Risk)
A hazardous tree is a living tree that presents a documented, imminent structural risk to persons or property. “Hazardous” is a specific legal and arboricultural designation — not just a tree that looks a bit rough. Under Toronto Urban Forestry’s emergency exemption criteria, a hazardous tree must show one or more of the following:
- Trunk cracks or splits spanning more than 50% of the trunk diameter
- A measurable lean greater than 15 degrees from vertical (especially toward a structure)
- Major scaffold limbs (over 4 inches diameter) showing imminent failure: splitting at the union, hanging by bark alone
- Root plate heaving — visible soil lifting at the base, indicating the root system is losing its anchor
- Significant crown failure following storm damage where remaining structure is unstable
The critical distinction: a hazardous tree is actively failing right now. A dead tree is already gone structurally but poses no active threat in the legal sense — it doesn’t qualify for the emergency exemption pathway because the City’s exemption criteria require imminent, documented risk from a living tree showing dynamic failure modes.
If you’ve had a recent storm and you’re dealing with a downed or partially fallen tree, our 24/7 emergency tree removal service covers the full assessment-to-removal process with 2-hour response.
Toronto Permits: What Chapter 813 Actually Says (No Exemptions for Dead Trees)
Toronto’s Municipal Code Chapter 813 (Trees) is the governing bylaw for tree removal on private property within city limits. The core rule: any tree with a trunk diameter ≥30cm measured at 1.4 metres above grade (DBH — diameter at breast height) requires a permit before removal. This applies regardless of whether the tree is healthy, dying, or 100% dead.
The myth we kill every week: “My tree is dead, so I don’t need a permit.” False — dead trees do not get a permit exemption under Chapter 813. Your arborist documents the tree’s dead status in their report, which helps the city process your application faster (they know there’s no canopy value to preserve), but the permit application is still mandatory.
Fines for unpermitted removal:
- Individual homeowners: $500 minimum per tree, up to $30,000
- Corporations/developers: Up to $100,000 per tree
- Replacement planting: The city may also require you to plant 1–3 replacement trees at your expense, depending on the DBH of the removed tree
The fine can be issued years after the fact — the City uses aerial photography and site inspections and has pursued cases 18–24 months after unpermitted removal.
Trees under 30cm DBH on private property (not in a ravine, not protected species) do not require a permit. If your tree is smaller, measure first before calling anyone.
Hazardous Tree Emergency Exemptions (How to Get Expedited Removal)
If your living tree shows genuine, documented immediate hazard, Toronto Urban Forestry allows an emergency exemption that bypasses the standard 30-business-day review. Here’s exactly how it works:
Step 1: ISA-Certified Arborist Assessment ($400–$600)
The arborist inspects the tree and prepares a formal hazard assessment documenting: species, DBH, location, specific structural failure observed, risk rating (low/medium/high/extreme), and urgency of removal. The ISA certification is mandatory — the City will not accept reports from uncertified contractors.
Step 2: Submit to Toronto Urban Forestry
Your arborist (or you, with their report) contacts Urban Forestry directly. The report is submitted with photos clearly showing the hazard condition. For genuine emergencies — roof-threatening leans, post-storm failures, trunk cracks exposing the core — turnaround is 48–72 hours.
Step 3: Exemption Approved — Remove Immediately
Once the exemption is approved, the tree can be removed without the standard permit fee ($100–$300 saved). The only requirement: within 7 days of removal, you must file notification with the City confirming the work was completed.
What this exemption saves you: 6–8 weeks of waiting on a standard permit review, plus $100–$300 in permit fees. Your only cost is the hazard assessment ($400–$600) plus removal ($1,500–$3,500 depending on size and conditions).
Important: Some contractors advertise “hazard removal, no permits needed.” This is misleading. The exemption still requires documentation and City notification. You still need a certified arborist report. TTR always handles this documentation as part of our hazardous removal service — no surprises.
Cost Comparison: Dead Tree vs Hazardous Tree Removal in Toronto
Cost by Tree Size (CAD)
| Tree Size | Dead Tree — Total Cost | Hazardous Living Tree — Total Cost |
|---|---|---|
| Small (under 30cm DBH / under 20 ft) | No permit needed — $600–$900 removal only | No permit needed — $700–$1,100 removal only |
| Medium (30–50cm DBH / 20–40 ft) | $1,650–$2,400 (permit + assessment + removal) | $1,900–$2,800 (hazard assessment + removal; $0 permit if exemption) |
| Large (50–75cm DBH / 40–60 ft) | $2,400–$3,400 (advanced decay rigging adds cost) | $2,700–$4,100 (high-risk rigging, emergency premium) |
| Very Large (75cm+ DBH / 60+ ft) | $3,400–$5,000+ (complex rigging, multiple crew) | $4,000–$6,000+ (emergency response, specialized equipment) |
Why dead trees sometimes cost more than you’d expect: Decay makes wood unpredictable. As a dead tree dries, internal voids form, load-bearing capacity becomes unknown, and chunks can shear without warning — what arborists call “widow-makers.” A dead 50-foot tree may take 2–3 hours longer to remove safely than a healthy tree of the same size, adding $200–$500 in labour. This is why we always inspect before quoting — the price difference between a freshly-dead tree and a tree that’s been dead for 3 years can be significant.
DIY vs Professional Removal
| Factor | DIY Removal | Professional Removal (TTR) |
|---|---|---|
| Permit handling | You navigate Chapter 813 alone; errors cause delays | TTR manages full permit or exemption application |
| Equipment cost | $400–$800 chainsaw rental + $200 chipper rental | Included in removal quote |
| Liability | You’re fully liable for property damage and injury | $5M liability insurance, WSIB coverage |
| Dead/hazardous tree risk | Extremely high — unpredictable failure; no rigging expertise | Controlled rigging, ISA-certified technique |
| Bylaw compliance | Fine risk $500–$100,000 if permit missed | Fully compliant; documentation provided |
| True cost (medium tree) | $600–$1,200 in equipment + $500+ fine risk + personal injury risk | $1,650–$2,800 all-in, zero fine risk |
Assessment Reports: Dead Tree vs Hazard Assessment (Which Do You Need?)
Dead-tree arborist letter ($300–$400): A written report from an ISA-certified arborist confirming the tree is 100% dead. Includes species ID, DBH measurement, observations confirming no living cambium, photos, and arborist’s recommendation for removal. This letter accompanies your Chapter 813 permit application. It will not get you an emergency exemption — but it does help the City process your application in roughly 25 business days instead of 30, because they can confirm there’s no canopy value to evaluate.
Hazard assessment report ($400–$600): A more detailed document required for emergency exemption requests. Includes everything in the dead-tree letter plus: a formal risk rating (ISA Tree Risk Assessment Qualification protocol), specific failure mode description (trunk crack dimensions, lean measurement, root plate assessment), photos documenting the hazard condition, and the arborist’s formal recommendation with urgency level. This is the document Toronto Urban Forestry needs to process a 48–72 hour exemption.
Can you use a hazard assessment report for a dead tree? Technically yes — but dead trees don’t qualify for exemption, so the extra cost of the hazard assessment ($100–$200 more than a dead-tree letter) wouldn’t help you skip the permit process. For dead trees, the standard arborist letter is the right tool.
Timeline Comparison: Standard Permit vs Emergency Exemption
| Step | Dead Tree (Standard Permit) | Hazardous Tree (Emergency Exemption) |
|---|---|---|
| Arborist assessment booked | Day 1–2 | Day 1–2 (urgent booking recommended) |
| Assessment completed + report written | Day 3–5 | Day 2–4 (expedited for genuine hazard) |
| Permit/exemption submitted to Urban Forestry | Day 5–7 | Day 4–5 |
| City review + approval | 25–30 business days (5–6 weeks) | 48–72 hours for genuine documented hazard |
| Tree removal scheduled | After permit issued (~6–8 weeks from start) | Within days of exemption (3–5 days total) |
| Storm season (May–Aug) delays | Urban Forestry backlogged — add 1–2 weeks | Exemptions still prioritized but may hit 5–7 days |
Storm season (May through August) floods Urban Forestry with permit applications and exemption requests. If your hazardous tree situation arises in this window, our team files with urgency framing and full documentation to stay at the front of the queue. Winter (December through February) is slower — standard permits often clear in 20 business days, and exemption reviews may complete in 5–7 days instead of 48–72 hours.
Toronto-Specific Permit Flowchart (Decision Tree)
Use this decision path when you spot a problem tree on your Toronto property:
START: You’ve spotted a tree that may need removal.
→ Step 1: Measure DBH (diameter at breast height = 1.4m above ground)
• Under 30cm DBH on private property, not in a ravine? No permit required — call TTR directly for removal quote.
• 30cm DBH or larger? Continue to Step 2.
→ Step 2: Is the tree living?
• Do a scratch test: scrape bark. Green/white cambium = living. Dry brown = dead.
• Tree is dead (brown cambium, no buds anywhere): → Dead Tree Path below.
• Tree is living (any green, any flexible branches): Continue to Step 3.
→ Step 3: Does the living tree show immediate structural failure risk?
Check: trunk cracks >50% of diameter / lean >15° toward structure / major limbs splitting / root plate heaving.
• No clear immediate risk: → Standard Permit Path (30 business days, $100–$300 fee, $300–$400 assessment).
• YES — active structural hazard: → Hazard Exemption Path (48–72 hours, $0 permit, $400–$600 assessment, immediate removal possible).
Dead Tree Path: Get ISA-certified dead-tree assessment ($300–$400) → File Chapter 813 permit application → Wait 25–30 business days → Remove after permit issued. Total: $1,650–$3,400 depending on size.
Hazard Exemption Path: Get ISA-certified hazard assessment ($400–$600) → Submit to Toronto Urban Forestry with urgency documentation → 48–72 hour review → Remove immediately upon approval → File notification with City within 7 days. Total: $1,900–$4,100 depending on size.
Cost Breakdown by Scenario (Real Toronto Examples)
Scenario 1 — Dead 30-foot oak in Scarborough:
Arborist dead-tree assessment: $350 | Permit fee: $100 | Removal: $1,200 (tree was recently dead, wood manageable) | Total: $1,650 | Timeline: 6–8 weeks (standard permit)
Scenario 2 — Dead 50-foot elm in North York (standing dead for 2+ years):
Arborist assessment: $400 | Permit fee: $150 | Removal: $2,000 (larger tree, advanced decay, slower rigging) | Total: $2,550 | Timeline: 5–7 weeks
Scenario 3 — Living 35cm maple with 20-degree lean in Etobicoke (immediate risk to house):
Hazard assessment: $450 | Permit fee: $0 (emergency exemption approved) | Removal: $1,800 (high-risk rigging for lean) | Total: $2,250 | Timeline: 3–5 days
Scenario 4 — Living 40cm oak with major crown dieback and trunk cracks in Markham (storm damage):
Hazard assessment: $500 | Permit: $0 (exemption) | Removal: $2,200 | Total: $2,700 | Timeline: 2 days (emergency response)
What-if scenario — North York homeowner who didn’t call:
A North York homeowner ignored a dead 45-foot maple for 18 months. When branches started shedding, he removed it himself, thinking the tree was dead and therefore exempt from permits. City issued a fine of $500 and required a $2,000 replacement planting. Had he called TTR for a $350 assessment and filed the Chapter 813 permit, total cost would have been $1,650 — with zero fines. Dead trees always need permits. Always.
“Our maple had a visible split in the trunk — I was terrified it was going to hit the garage. TTR’s arborist came out, confirmed it was a genuine hazard, filed the exemption with Urban Forestry, and we had it down in four days total. Cost was $2,250 all in. Saved us the 6-week wait and I didn’t have to figure out the permit process at all.”
— Marcus L., Etobicoke homeowner, 2026
Can You Remove a Dead Tree Without a Permit? (The Truth)
No. Not if it’s ≥30cm DBH on private property in Toronto. Full stop.
Chapter 813 of Toronto’s Municipal Code protects trees based on size, not health status. The reasoning is sound from the City’s perspective: a large dead tree that gets removed without a permit is still removing canopy from the urban forest, and the City wants a record and an opportunity to require replacement planting if the removal doesn’t meet standards.
Common scenarios we see homeowners get wrong:
- “The tree fell over in a storm — I just cut up the wood.” If the trunk was ≥30cm DBH and on your property, technically this still falls under notification requirements. In practice, fallen trees are treated with more flexibility by the City, but it’s worth a quick call to Urban Forestry to document it.
- “It’s a diseased tree, the EAB killed it.” Emerald Ash Borer-killed ash trees still require permits if ≥30cm DBH. On top of that, disposal has special requirements — ash wood and stumps must be labeled with PHI (Pest Host Indicator) and cannot be transported out of the regulated area. TTR handles all of this; typical disposal fee of $20–$50/tonne is included in our removal quotes.
- “My neighbour wants the tree down too.” Irrelevant to the permit requirement. You need the permit regardless of neighbourhood agreement.
The only private-property scenarios where no permit is needed: trees under 30cm DBH (not in a ravine), or trees explicitly listed as exempt species by Urban Forestry. For everything else, get the permit.
Neighbourhood Pricing Breakdown Across the GTA
TTR services all of Toronto, Scarborough, North York, Etobicoke, Vaughan, Mississauga, Markham, and Brampton. Chapter 813 permit requirements apply within Toronto’s city limits. For properties in Mississauga, Vaughan, Markham, and Brampton, municipal bylaws differ — contact your local municipality for the specific permit threshold and process. Our team knows each municipality’s requirements and will guide you through the correct pathway regardless of where your property is.
Pricing variations across the GTA are driven primarily by site access (tight lots in central Toronto vs more open yards in Brampton or Vaughan) and species density (ash trees in Scarborough with EAB require special handling; large sugar maples in North York and Etobicoke are common and well-understood). Typical removal quotes:
- Central Toronto / Scarborough / North York / Etobicoke: $1,200–$3,500 for medium-to-large trees (tighter access, urban rigging)
- Vaughan / Markham / Brampton: $900–$2,800 for medium-to-large trees (generally better access, lower rigging complexity)
- Mississauga: $1,000–$3,000 (mix of urban and suburban access conditions)

FAQ: Dead vs Hazardous Tree Removal Questions
Can I remove a dead tree without a permit in Toronto?
No. Any tree ≥30cm DBH on private property in Toronto requires a Chapter 813 permit regardless of health status. Dead trees are not exempt. Your arborist documents the deadness in their letter (which can speed the City’s review by 3–5 days), but the permit application is still mandatory. Removing without a permit risks a $500–$30,000 fine plus mandatory replacement planting costs.
Is a dead tree considered hazardous under Toronto’s exemption rules?
No. Legally and under Toronto Urban Forestry’s emergency exemption criteria, a dead tree is not “hazardous” in the exemption sense. A hazardous tree is a living tree showing active structural failure — dynamic risks like cracks propagating under load, leaning roots pulling, or crown collapse in progress. A dead tree is already structurally gone; it doesn’t show the active failure modes the exemption was designed to address. Dead trees go the standard permit route.
What’s the fastest way to legally remove a tree in Toronto?
If the tree is living and you can document immediate structural risk (trunk cracks >50% diameter, lean >15°, major limb failure), file for emergency hazard exemption via an ISA-certified arborist. Turnaround from Urban Forestry: 48–72 hours. If the tree is dead, the fastest path is filing immediately with a complete dead-tree arborist letter and full application — Urban Forestry typically processes these in roughly 25 business days (slightly faster than the standard 30 because there’s no canopy-value evaluation needed).
My dead tree is actively shedding large branches. Can I get an emergency exemption?
Possibly, with the right framing. If the tree has any remaining living tissue (technically alive but rapidly declining) and the branch shedding poses immediate risk to persons or property, an ISA-certified arborist may be able to frame the assessment as a hazard exemption. If the tree is genuinely 100% dead with no living tissue, the exemption does not apply — standard permit is required. Call us and we’ll assess the same day.
Do I really need an ISA-certified arborist, or will any tree company work?
For Toronto permit applications and especially for hazard exemption requests, ISA certification is required. Toronto Urban Forestry will not accept assessment reports from uncertified contractors for permit purposes. ISA certification ensures the report meets the professional standard the City trusts. All TTR assessments are conducted by ISA-certified arborists — this is non-negotiable on our end too.
What happens if I remove a tree without a permit in Toronto?
Fines start at $500 per tree for individual homeowners and go up to $30,000. Corporations and developers can face fines up to $100,000 per tree. The City may also require you to plant 1–3 replacement trees at your expense, proportional to the DBH of the removed tree. Enforcement can happen years after removal — aerial photography and City inspection records make it traceable. The permit cost ($100–$300) is a small fraction of the fine risk.
Can stump grinding be done without a permit after the tree is removed?
Yes. The Chapter 813 permit covers the standing tree removal. Once the tree is removed under a valid permit (or emergency exemption), stump grinding is a separate service that does not require its own permit. TTR includes stump grinding quotes in most removal packages — ask when you call for your assessment.
If a dead tree is not hazardous, do I have to remove it?
No — Toronto does not require removal of dead trees on private property. Removal is your decision. However, dead trees attract wood-boring insects (termites, carpenter ants) and can fail without warning, especially during storms. We recommend removing dead trees ≥30cm DBH within 1–2 years to prevent property damage and eliminate the pest-harbouring risk. Waiting longer usually means the wood deteriorates further, which adds rigging complexity and cost.
Does homeowner insurance cover dead tree removal in Toronto?
Standard homeowner insurance does not cover the proactive removal of a dead or healthy tree — that’s considered maintenance. However, if a dead tree falls and damages your property or a neighbour’s property during a storm event, your insurance may cover the removal and repair costs. Document everything immediately if this happens. This is one reason to act before the tree falls rather than after.
