You may also have signed an agreement that the property has been licensed. This is not enough to make the agreement a license. Rental agreements must be in writing and the landlord must provide a copy to the tenant before the rental begins. But even if no formal written agreement is reached, the Housing Rental Act applies. Landlords and tenants cannot escape their obligations by not taking their consent in writing. An oral agreement can also be changed. The change will usually also be verbal. In the event of a dispute, proof of the change can be made if: The lessor/agent must complete and sign a declaration of surety (Form 2), if a rental loan is calculated for the lease, file it and the bail indemnity received with the RTA within 10 days.
