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.
Do it automatically with LandlordEzy
You don't have to calculate any of this by hand. LandlordEzy prepares your N1 — Notice of Rent Increase for you: it pre-fills the current guideline and the new rent, sets the earliest legal effective date (90 days out and at least 12 months since the last increase), fills the official LTB Form N1, and lets you e-sign and serve it. When you serve it, the increase is automatically applied to your rent ledger on the effective date — and you can add the last-month-rent deposit top-up in one click. See how the automated N1 works →
