Yes, a landlord may review the rent during a periodic tenancy, but they must follow the rent-control rules that apply to your tenancy. Generally, rent can be increased no more than once every 12 months and the landlord must give at least 90 days’ written notice, using the required procedure; limits may also apply to the amount of the increase. Check the RTB’s current guidance for your tenancy’s start date and circumstances, and contact the RTB if you believe the notice is invalid. Any dispute outcome depends on the individual facts and the RTB process.
