Ontario's 2027 Rent Increase Guideline Is 1.9%: What It Means

Published 2026-08-14 · PaperNorth

Some rare good news in your mailbox's future: Ontario has set the 2027 rent increase guideline at 1.9% — down from 2.1% in 2026. If your unit is rent-controlled, that's the most your landlord can raise your rent in 2027 without special permission from the Landlord and Tenant Board.

What was announced

The province published the 2027 guideline on its official residential rent increases page in late June 2026. The guideline is tied to Ontario's Consumer Price Index and is capped by law at 2.5% no matter what inflation does. For 2027 the math worked out to 1.9% — the lowest guideline in several years.

• Applies to: increases taking effect on or after January 1, 2027, for most units first occupied before November 15, 2018.
• Doesn't apply to: units first occupied after November 15, 2018 (no guideline cap), vacant units being re-rented (no limit between tenancies), and some other exemptions like commercial spaces.

The dates that matter to you

• Your landlord must give at least 90 days' written notice on the proper form (an N1) before any increase.
• That means for a January 1, 2027 increase, the earliest a valid N1 can be served is October 3, 2026. Expect N1 forms to start appearing in mailboxes this fall.
• Rent can only go up once every 12 months. If your rent went up mid-2026, a January 2027 increase isn't allowed — the 12-month clock runs from your last increase.

What to check when your N1 arrives

1. The percentage. Is the increase 1.9% or less (for 2027 effective dates)? If it's more, is there an LTB order approving an above-guideline increase (AGI)? No order and no exemption = you generally don't have to pay the excess.
2. The timing. Count the days between when you received the notice and the effective date — fewer than 90 days makes the increase invalid until properly re-served.
3. The 12-month rule. Check the date of your last increase.
4. The form itself. A rent increase demanded by text message or a note under the door isn't a valid notice — it must be the official form with the required information.

If your building isn't rent-controlled

Units first occupied after November 15, 2018 aren't covered by the guideline — the landlord can propose any amount with proper notice. You still have rights: the 90-day notice and 12-month rules still apply, and you can try to negotiate (landlords would usually rather keep a good tenant than gamble on a vacancy). If you're not sure when your unit was first occupied as a rental, ask in writing — and keep the answer.

Common mistakes tenants make

• Paying an invalid increase "to keep the peace." Once you pay a higher rent for 12 months without disputing it, it can become your lawful rent. Question it early, in writing.
• Assuming every increase is legal because it's on a form. The N1 form doesn't verify itself — the percentage, timing, and 12-month rule are on you (or your tools) to check.
• Ignoring the exemption question. Many tenants in newer buildings believe they're protected by the guideline when they aren't — and vice versa: many tenants in older buildings pay above-guideline increases they never had to accept.
