Rent Increases in Ontario: What Your Landlord Can — and Cannot — Do
Every year, tenants across the GTA receive rent increase notices — and many pay increases that were never legal in the first place, simply because they did not know the rules. Landlords, for their part, sometimes lose a legitimate increase because the notice was defective. The rules under the Residential Tenancies Act are strict, and they cut both ways.
The Guideline: 2.1% for 2026
For most rented residential units, Ontario caps the annual rent increase at a guideline percentage set by the province. The guideline is 2.1% for 2026 (it was 2.5% for 2025). If your rent is $2,000 a month, a guideline increase for 2026 can add at most $42.
The Rules That Trip People Up
A rent increase is only lawful if all of the following are met:
- Once every 12 months. Rent can be increased only once in any 12-month period, counted from the last increase or from the day the tenancy began.
- 90 days' written notice. The landlord must give written notice of the increase at least 90 days before it takes effect, using the proper Landlord and Tenant Board form. A text message, an email, or a verbal demand is not proper notice.
- The right amount. Unless the unit is exempt or the Board has approved more, the increase cannot exceed the guideline.
An increase that skips any of these steps is not valid — and a tenant who has been charged an unlawful increase can dispute it at the Landlord and Tenant Board within 12 months of being charged.
Not Every Unit Is Covered
This surprises many renters: the guideline does not apply to buildings, additions, and most new basement apartments first occupied after November 15, 2018. In those units, the landlord still must follow the 12-month rule and give 90 days' proper notice, but there is no cap on the percentage. Between tenancies, landlords may also negotiate a new rent freely with a new tenant.
Above-Guideline Increases
In limited situations — for example, certain major capital work — a landlord can apply to the Landlord and Tenant Board for approval to raise rent by more than the guideline. Until the Board actually approves it, the landlord cannot collect the extra amount.
What To Do
If you are a tenant, do not simply start paying a higher rent because a letter arrived. Check the date, the form, the math, and whether your unit is even covered. If you are a landlord, get the notice right the first time — a defective notice can cost you a full year's increase.
