We live in a country with a powerful legislative and common-law tradition of protecting an individual’s right to own property within secure boundaries. However, protecting your property boundaries is your responsibility. The government will not actively help with a problem like a neighbour’s fence being built on your side of the property line or any other issue relating to your particular property borders, including locating and defining the limits of your land.
Local governments do provide services to aid in boundary protection, including zoning by-laws and fence viewers. Zoning by-laws cover issues such as how close to a property line a house or other structure may be built. Fence viewers have prescribed procedures for assessing the costs and aesthetics of new fences when neighbours are in dispute. Beyond this owners must resolve their differences privately. Also note that the police will not get involved unless your property or belongings are damaged or destroyed in a criminal act.
