If the behaviour of an animal has interfered with the reasonable enjoyment of the residential complex by the landlord and/or other tenants, you may issue a notice of early termination of the tenancy. You can issue Form N5 – Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding. This notice needs to have details about the issues such as the unclean state and foul odour in the rental unit. The tenant will then have seven days to rectify the problems. Form N7 may be given to the tenant instead of the N5 where the landlord and the tenant live in the same residential complex and the landlord has less than 3 residential units.
