Even though you are the owner of the property, your tenants still have a right to privacy. Every province has mandated landlord-tenant legislation, e.g. the Residential Tenancy Act.These regulations all have some clause explicitly describing a tenant's right to "quiet enjoyment" of the rental property, which refers to their rights to reasonable privacy and freedom of unreasonable disturbance.As a landlord, if you infringe upon these rights by entering an apartment unannounced, your tenant could pursue legal action against you.The only times you, as a landlord or property manager, do not need a Notice to Enter are:
In a case of emergency: for instance, if you see smoke or water coming out from under the rental unit door and think the property is either on fire or flooding.
When the tenant grants you permission to enter: for example, if the tenant calls you about repairs and expresses consent for you or a repair person to enter the unit.
If a tenant abandons the property: for example, if the tenant hasn't paid rent for a few months and you haven't heard from the tenant or can't reach them, you may treat the unit as abandoned and enter.
