- How responsibility for a fallen tree applies depends on your situation, so it is worth confirming with a lawyer.
- Taking photos, calling your insurer promptly and staying calm and factual with your neighbour are sensible practical steps.
- Boundary-location questions are for the owners to resolve, and fence-viewer arbitration does not decide where the boundary is.
Few things feel worse than a phone call saying your tree has landed on your neighbour's roof, fence or car. You may be worried about the damage, the cost and whether the neighbour will blame you. Searching online often turns up conflicting answers.
The honest answer is that responsibility usually depends on the facts. This article explains the ideas that tend to matter, the practical steps to take right away, and when to get legal advice. It does not state a fixed rule, because each case turns on its own circumstances.
Why there is no simple yes or no
People often assume the owner of the tree is automatically responsible. How this applies depends on your situation, so it is worth confirming with a lawyer.
Questions that often come up are whether anyone knew about a problem with the tree, what was done about it, and what the weather was like when it came down. Because these details differ from one situation to the next, two similar-looking incidents can end up with different outcomes.
Facts that tend to matter
- The condition of the tree: was it dead, leaning, hollow or diseased?
- What you did: did you inspect, prune or remove the tree, and do you have records?
- The weather: was there a severe storm or high wind at the time?
- Where the tree stood: wholly on your land, wholly on your neighbour's, or on the boundary.
- The damage: what was hit, how severe, and whether it can be repaired.
Ownership can be unclear if the trunk sits near the property line. The arbitration process under the Line Fences Act, for instance, does not decide where the boundary is, and owners must resolve boundary-location questions themselves. A survey is often the first step in a boundary-tree situation.
How insurance usually comes into it
What your policy covers depends on its wording, limits and deductible, so it is worth confirming the details with your insurer.
Because wording varies, read your policy and ask your insurer directly. Whether and when you need to tell your insurer about the incident depends on your policy, so it is worth confirming with your insurer or a lawyer.
Your tree, your neighbour's tree, and municipal rules
Some municipalities regulate the cutting or removal of certain trees, and the details vary by city. Before removing a large or damaged tree, check whether your municipality requires a permit. Fence, pool and tree rules, fees and exemption processes are municipal and vary by city.
| Situation | What it generally depends on |
|---|---|
| Tree on your land, healthy, storm damage | The facts of what happened; worth confirming with a lawyer |
| Tree on your land, known to be dying | What you knew and whether you acted |
| Tree on the boundary | Where the boundary lies, which owners must resolve themselves |
| Tree on a road allowance | The municipality involved; a lawyer or the municipality can confirm |
Road allowances are laid out by Crown surveyors and are generally 66 feet wide. The Province notes that waterfront owners often build on road allowances, which can cause problems with title, mortgages and insurance. If a tree stood on or near a road allowance, who owns or is responsible for it depends on the facts, so it is worth confirming with the municipality or a lawyer.
If a boundary fence was damaged too
A falling tree sometimes takes a fence down with it. The Line Fences Act gives owners of adjoining properties in most of Ontario a dispute-resolution procedure for fences on a shared boundary line, but it does not cover fences that are not on the boundary line. Whether it fits your situation depends on the facts.
| Topic | What the Act's procedure involves |
|---|---|
| When it applies | Only where owners cannot agree and a line fence needs to be built, or needs reconstruction or repair; neighbours are encouraged to talk first |
| If one owner repairs everything first | If an owner builds, reconstructs or repairs an entire fence on their own initiative and then asks the neighbour to pay part, the fence-viewer procedure does not apply |
| How it starts | The owner asks the municipality to assign fence-viewers using Form 1 |
| The viewing | Three fence-viewers must be present, and they can address only how the work is apportioned and the description of the fence, including materials |
| The result | The fence-viewers issue an award and allocate the costs of the proceeding between the owners |
| Appeals | An owner has 15 days from receiving a certified copy of the award to appeal |
A municipal council may pass a by-law exempting all or part of its area from the Act, so whether it applies depends on your municipality. The process deals only with the fence. It would not decide who pays for damage to a house or a car.
What to do next
- Make sure everyone is safe and stay away from downed power lines.
- Take photos and video of the tree, the stump, the damage and the weather conditions.
- Call your insurer promptly and follow their instructions on cleanup.
- Be kind and factual with your neighbour; avoid admitting or denying fault in writing before you have advice.
- Keep receipts for emergency repairs, tarps and tree removal.
- Gather any records of past tree care, inspections or complaints.
- Get legal advice if there is a demand letter, a large loss or disagreement about who owned the tree.
Whether you are the tree owner or the neighbour, a lawyer can review your facts and explain where you likely stand.
Frequently asked questions
Am I automatically responsible if my tree falls on my neighbour's house?
Whether you are responsible depends on the facts, so it is worth confirming with a lawyer. A lawyer can assess your specific situation.
Does a storm mean I am off the hook?
How a storm affects your situation depends on the facts, so it is worth confirming with a lawyer.
Should I contact my insurer even if I think it was not my fault?
Whether and when you need to report the incident depends on your policy, so it is worth checking your policy wording and confirming with your insurer or a lawyer. Whatever you decide, keep your photos and records of the incident.
What if the tree was on the property line?
Ownership may be unclear. Boundary-location questions are for the owners to resolve, and fence-viewer arbitration does not decide where the boundary is. A survey and legal advice can help.
