Neighbour's Tree Damaged My Fence in a Storm: Who Pays in Ontario?

After a storm, you find a large branch or a whole tree from next door lying across your fence. The fence is broken, the yard is a mess, and you want to know whether your neighbour, the weather or your insurance company will cover the repair.

There is no automatic answer. How responsibility applies depends on your situation, so it is worth confirming with a lawyer. This article covers the first steps, how a shared boundary fence is treated under the Line Fences Act, and when insurance or a lawyer comes into the picture.

Start with safety, photos and your insurer

Keep people away from the area if the tree is unstable or touching power lines, and call your utility rather than touching anything. Once it is safe, record the damage before anything is moved.

• Take photos and video of the tree, the fence and the surrounding area, including the stump or base of the tree.
• Note the date and time of the storm and any weather warnings.
• Take photos of any signs the tree was already dead, rotten or leaning, if you have older pictures.
• Get a written repair quote or two.
• Notify your home insurer promptly and ask how a claim would work and what your deductible is.
• Keep damaged pieces until your insurer says you can dispose of them.

Many people find that their own home insurance is the quickest path to getting a fence repaired, even when a neighbour's tree is involved. Policies differ on fence coverage and deductibles, so check yours.

Does the neighbour have to pay?

Whether your neighbour is responsible depends on your situation, so it is worth confirming with a lawyer.

If you think the tree was already in poor shape, evidence matters: earlier photos, any written warnings you sent and an arborist's view of the stump. A lawyer can tell you how those facts line up in your situation.

The Line Fences Act and a shared fence

If the damaged fence sits on the boundary between your lot and your neighbour's, the Line Fences Act may be relevant to repair costs. The 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 that line.

The procedure applies where the owners cannot agree and a line fence exists that one owner thinks needs reconstruction or repair. Informal discussion between neighbours is encouraged first. Owners start the process by asking the municipality to assign fence-viewers, using Form 1, Request for Fence-Viewers. Three fence-viewers must be present at a viewing, and they can address only how the work is apportioned between the owners and the description of the fence, including materials.

Two points catch people out. First, if you rebuild or repair the entire fence on your own initiative and then ask your neighbour to pay part of the cost, the fence-viewer procedure does not apply. Second, a council may exempt all or part of its area from the Act by by-law, so whether it applies depends on your municipality. Fence-viewers deal only with fence disputes and do not decide where the boundary is.

What the award process looks like

If fence-viewers are used, the municipal clerk sends notices to the parties and the fence-viewers, using Form 2 and Form 3, and the viewers issue an award on Form 4. After the viewing, they also allocate the costs of the proceeding between the two owners.

An owner who is unhappy with the award has 15 days from receiving a certified copy to appeal, and an award sent by registered mail is deemed received seven days after it is sent. The 2026 appeal fee is $406.05, adjusted each January 1 by Ontario's CPI. Only the original award can be appealed. Because the deadline is short, speak with a lawyer quickly if you want to challenge an award.

Practical next steps

• Make the area safe and photograph everything before cleanup.
• Call your insurer early and ask about fence coverage and your deductible.
• Speak with your neighbour calmly and share your photos and quotes.
• Confirm whether the fence is on the boundary line, and whether your municipality has exempted itself from the Line Fences Act.
• Avoid rebuilding the whole fence before you have talked to your neighbour if you hope to share the cost through the Act.
• Speak with a lawyer if the neighbour refuses to engage, the amount is significant or the boundary is unclear.
