If you file a Tenant Application about Maintenance with the LTB, you can ask to pay some or all of your rent to the LTB instead of the landlord until your application has been decided. Complete the Request to Pay Rent to the Board on a Tenant Application about Maintenance. You will have to justify why you are not paying the landlord directly. The LTB will decide whether to grant your request.
