Rent increases & the guideline
How much and how often you can raise the rent in Ontario.
General information, not legal advice. Ontario rules and timelines change — always confirm the current forms and requirements with the Landlord and Tenant Board or a licensed paralegal before acting.
The rules
For most tenancies you can raise the rent once every 12 months, with at least 90 days' written notice on the official N1 form, and only by the annual rent increase guideline set by the province each year.
Exceptions
Units first occupied after a cut-off date may be exempt from the guideline (but still need notice). Above-guideline increases (AGIs) require a separate LTB application. Always confirm the current guideline percentage and the exemption date on the Government of Ontario / LTB site before issuing an N1.
