Neighbour Property Disputes in Ontario: Fences, Trees & Encroachments
Few disputes are as stressful as those with a next-door neighbour. From fences that cross the property line to overhanging branches and encroaching structures, Ontario has specific laws governing each type of dispute — and most can be resolved without expensive litigation.
Fence Disputes: The Line Fences Act
Ontario's Line Fences Act governs boundary fences between properties outside of municipalities (rural land). Within most municipalities, the local zoning bylaw governs fence height, placement, and materials.
- Cost sharing: Under the Act, both neighbours generally share the cost of building and maintaining a line fence, unless one benefits more.
- Fence viewers: If you and your neighbour cannot agree, either party can request local fence viewers (municipal arbitrators) to determine cost allocation.
- Municipal rules: In cities/towns, municipal bylaws typically restrict fence height (often 2m in the rear yard, 1m in the front yard) and require permits for taller structures.
Trees on or Near Property Lines
Tree disputes are governed by common law property principles, not a single Ontario statute:
| Situation | Legal Position |
|---|---|
| Tree trunk entirely on one property | That owner owns the tree; neighbour cannot remove it |
| Trunk straddles both properties | Both own the tree jointly — neither can remove without consent |
| Branches/roots cross the line | Neighbour may trim to the property line at their own cost, but cannot damage the tree |
| Fallen tree damages neighbour's property | Liability depends on whether the tree was diseased/hazardous and the owner knew or should have known |
Encroachments
An encroachment occurs when a structure (fence, shed, deck, addition) is built partially on a neighbour's land. Options for the affected landowner include:
- Demand removal: The encroaching structure must be moved at the builder's cost
- Negotiate an easement: Grant a formal right to use the encroached area in exchange for payment
- Sell the encroached strip: If the encroachment is minor, selling a sliver of land may be the practical solution
- Sue for trespass: Small Claims Court for damages if encroachment causes loss of use or value
Easements and Right-of-Way Disputes
An easement is a registered right to use a portion of someone else's land. Common examples: utility easements, shared driveway access, drainage rights. If a neighbour is blocking your easement or using your land without a registered right, you can:
- Apply to court to enforce the easement or obtain an injunction
- Claim damages for interference
- In some cases, acquire prescriptive easement rights after 20 years of open, continuous, uninterrupted use
Resolving Disputes Without Court
- Get a property survey to confirm exact boundaries before taking any action.
- Send a formal written letter documenting your concern and requested remedy.
- Use municipality's bylaw enforcement department (free) for fence height, setback violations.
- Request fence viewers (under Line Fences Act) for rural fence cost disputes.
- Pursue Small Claims Court (up to $35,000) for damages or removal of minor encroachments.
