A landlord can serve a valid Notice of Termination without first involving the RTB, but they cannot lawfully remove you themselves. They must follow the required notice period and legal rules, and cannot change the locks, cut off services or use intimidation to make you leave. If you believe the notice is invalid or you remain after it expires, the landlord will generally need to use the RTB dispute resolution process to seek possession. The RTB will decide any dispute based on the tenancy’s facts, so consider checking the notice with the RTB or a solicitor promptly.
