Ontario rent-increase timing: records to gather before you open a form
If a possible rent increase has put a date on your calendar, start by putting the underlying records in one place before you open a form. Ontario’s official overview says that, in most cases, at least 12 months must have passed since the last rent increase or since the tenancy began. It also says written notice in the proper form must be given at least 90 days before an increase takes effect. This is general information, not legal, tax, accounting, or professional advice. It does not decide whether a particular unit is covered, which form applies, what amount is permitted, or what date applies to a particular tenancy.
Begin with the dates you already have
Ontario’s Residential rent increases page is a useful official starting point because it states those general timing rules and describes limits on the rent-increase guideline. Before relying on a saved date, notice, or spreadsheet, gather the records that show:
- the tenancy start date you have on file;
- the effective date of the last rent increase, if any;
- the current rent and the notice or correspondence you already hold; and
- the date you are considering, without assuming it is valid.
This is a records-preparation list, not an official checklist or a conclusion about what anyone must do. Re-open the current official source before acting, because rules, forms, and guidance can change.
Do not treat the guideline as a universal answer
Ontario says its guideline is the maximum increase most landlords can make in a year without Landlord and Tenant Board approval. The same official page lists situations where the guideline does not apply, including certain newer units, a rental unit when a tenancy turns over, community housing, long-term care homes, and commercial properties. The page also says there can be applications to the LTB for approval to increase rent above the guideline.
That is why a percentage alone cannot answer every question. The practical next step is to compare your records with the current official material and get qualified help for your facts if the rule, exception, form, amount, or timing is unclear.
Open the current LTB material only after you have the basics
The LTB’s Forms, filing and fees collection lists the current notices of rent increase, including N1 and N2, with their instructions. It is a place to find official materials—not a reason to assume either notice is right for a particular tenancy. The LTB collection also carries its own notice that it is updating processes, forms, and rules following 2026 legislative changes.
A small dated record can make that comparison easier: note the official page you opened, when you opened it, and the document version or instruction page you reviewed. It will not make a legal decision for you, but it can help you avoid treating an old download or a remembered date as current official material.

The Brief is produced by the same team that operates EaseLease, a Canada-first rental-record tool for landlords with roughly 1–5 units. EaseLease helps organize property, unit, and tenant records, income and expenses, receipts, reminders, and exports. It does not select or file LTB forms, advise on notices or deadlines, communicate with tenants, or provide legal, tax, or accounting advice.
