Laws regarding fence line ownership – The Law


Q: Can one property owner remove a fence line without the neighbour’s permission? If a property is posted “no trespassing” can the neighbour enter the land and erect a fence on land that is not hers? Can a surveyor do a survey on land that is posted “no trespassing” without permission of the landowner? If a survey shows the fence line is not on the boundary line, what steps must be taken to move the fence to its correct location?

A: Fence rules are somewhat ambiguous and while in my years of writing this column I have received questions regularly on fence disputes, my research shows few such disputes go to court. I assume that in the end, good-neighbour polices prevail.

You raise two issues: What obligations does an owner have to fence and who has property rights in the fence?

Fencing obligations are set out in the Line Fence Act of Alberta, from where you write. Section 2 (1) says when two owners or occupiers of adjoining parcels want to erect a line or boundary fence, both of them shall bear the expense. Subsection 2 states that if the owner or occupier of a parcel erects a line fence, the owner or occupier of the adjoining parcel will contribute to the fence as soon as he receives any benefit.

While the act does not state if you have animals you must fence, the stray animals legislation makes the owner of stray cattle liable for damages.

In my view, the combined effect of these laws is to require fencing. Note that in Manitoba and Saskatchewan, municipalities can allow animals to wander at large.


If a person has erected a fence, obviously he is the owner. However, this does not necessarily mean the owner can do with it as he wishes. If the neighbour has contributed to the fence, then the neighbour also has an interest.

Even if the neighbour hasn’t contributed, it seems to me there is a possibility that the neighbour may have cattle in the future and therefore may require the fence.

Once the neighbour has cattle, he must contribute to its upkeep. So the neighbour may have a future interest in the fence built by the other.

If neighbours can’t agree, the law sets out an arbitration procedure for dealing with disputes.

Essentially, each owner appoints an arbitrator and together they will try to resolve the dispute. If the arbitrators can’t agree, they can appoint an umpire. If one party refuses to appoint an arbitrator, the other can ask a justice of the peace to do so.


In my opinion there is no legal requirement that the fence be on the exact boundary line. The arbitration process allows the arbitrators to decide “the proper location” of the fence line and provides that their decision does not affect “title to the land.” That can only be determined by a survey. Surveyors have the right to cross private property to carry out surveys. In Alberta, the surveyor is liable for any damage the surveyor or his assistants cause.

Is it trespass if one neighbour puts a fence on the other’s land? First, the law contemplates that the fence might not be exactly on the boundary line. Even if it was trespass, there is in law the concept that some wrongs are so minor that the law will not intervene.

In my view, unless one owner deliberately placed the fence well over the boundary line, there is no trespass.

Fence laws are similar in most other provinces.

    FENCING LAW VS HERDING LAW: I understand that Manitoba adopted the fencing law which means if you have property and do not want livestock upon your property (railroads, highways,etc.) you have to fence off your property. I would like to have more details on this law

    My neighbor has just installed his new livestock fence starting at our mutually-shared survey stake, straight on a tangent that is 5 to 10 ft. on my property side of the surveyed boundary by the time he reached 1500 ft. along our joint property boundary. If he continues on this same tangent he will be maybe 7 to 15 ft. on my side of the line, when he reaches the opposite side of the quarter section.
    What steps must I take to reclaim my property?

    • Hi Tony,

      I’m no expert by any stretch, but I would suggest that a good chat with your neighbour about your concerns would be a good place to start.

    I have no livestock on my 25 acres but the owner of the rest of the quarter section does. Who is obligated to put up a fence?

    We have a chain link fence with a beautiful vine growing on it to allow for privacy.
    The neighbour just maliciously and spitefully cut the vine back to the fence and it will now die.
    I live in Canada, northern Ont.
    Is there anything I can do about this?
