The Residential Tenancies Act does not apply when a tenant rents a room in the landlord’s home and shares the kitchen and living room with the landlord. If the tenant does not pay rent one month, the landlord is under no obligation to give the tenant a 14-day notice to end the tenencay. The landlord could ask the tenant to leave immediately for failing to pay rent. Tenants who live with their landlords do not have the same protections as tenants who are covered by the Residential Tenancies Act.
If the landlord and tenant share living space, it is a very good idea to have a written contract setting out the rules that both the landlord and tenant must follow to provide some basic protections.
