You can use the RTB’s online portal to submit an application, upload supporting documents, view case updates and respond to requests during the dispute process. Create an account with an email address you check regularly, keep your application confirmation, and make a note of any deadlines shown in the portal or sent by email. Upload clear copies of relevant records, such as the tenancy agreement, notices, rent records and messages, and keep the originals. The RTB decides the dispute based on the evidence and circumstances, so check the RTB’s official guidance or contact the RTB if you have difficulty accessing the portal.
