Can the landlord or tenant ever “break the lease”? Can the landlord require a tenant to provide proof of insurance as a condition of the lease? Does anyone residing in the property need to be mentioned on the lease? A lease is a contract between a lessor and a tenant (or tenant) that sets the rules that both parties will follow. Leases are also called residential or rental agreements. Some Alberta organizations have developed leases for the Residential Tenancies Act and provided the forms for purchase. For more information, see our page on forms. Are you or your family homeless or threatened with homelessness? They can receive referrals to housing and assistance services through a coordinated access system. Please contact Pulse. Community agencies can serve as single access points where people affected by homelessness or threatened with homelessness can benefit from help and resources.
