First, check that your issue falls within the RTB’s jurisdiction and gather your tenancy agreement, messages, notices, payment records and other evidence. Apply through the RTB’s online dispute resolution service, providing the parties’ details, tenancy address, facts of the dispute and outcome you are seeking; an applicable fee may apply. The RTB will notify the other party, and the case may proceed through mediation or adjudication, followed by a written decision. Check current deadlines, fees and procedures on the official RTB website, and consider legal advice for a complex matter; any outcome depends on the individual evidence and RTB process.
