Neighbourhood annoyances, or nuisances, can take many forms. They can emanate from an encroachment on one’s territory or rights of way, or dangers emanating from a neighbour’s property or activities, or simply noises, odours, trees, views, etc.
Some disturbances are regulated by the Law: for instance, in a scenario where the roots or branches from a tree located on your neighbour’s land threaten to damage your property or prevent you from enjoying it, you could most definitely require said neighbour to either trim or cut them off. If your neighbour refuses to do so, you could ask the court to order the neighbour to cut them off. You have the same right to enforce such an action if your neighbour’s tree or its branches threaten to fall on your property and damage it.
Municipal by-laws generally specify the maximum decibel level for certain situations and they also specify the fines for the offenders. You should therefore consult the municipal by-laws prior to taking specific measures to fix a problem. Co-ownership agreements or building regulations may also have their specific guidelines for noise and these can be stricter than those of the municipality.
