When a rental property is sold and there is a lease in place, the landlord cannot give notice to terminate the tenancy. The new owner would have to honour the existing lease. However, if your tenants are willing to move out earlier, ask them to sign a Form N11 which is a mutual agreement between the landlord and the tenant to terminate the tenancy. This form can be obtained from the Landlord and Tenant Board’s website at https://tribunalsontario.ca/ltb/forms
