How Often Can Ontario Landlords Raise Rent? Legal Limits Explained

Affordable Housing & Subsidies Ontario 5 min read · published March 09, 2026 Flag of Ontario

Many tenants in Ontario are concerned about rising rent, especially in today’s competitive rental market. If you’re wondering how often your landlord is allowed to increase your rent, or what rules and notifications they must follow, you’re not alone. Understanding these rules will help you protect your home and budget—and ensure you’re treated fairly under the law.

How Often Can Rent Be Increased in Ontario?

Ontario’s Residential Tenancies Act, 2006 regulates when and how much your rent can go up. For most private residential units, landlords can only increase your rent once every 12 months. The annual rent increase guideline is set by the Ontario government and applies to most tenancies, but some exceptions apply (for example, newer buildings or certain subsidized housing units).

  • Frequency: One increase allowed every 12 months.
  • Notice Required: At least 90 days' written notice before the new rent takes effect.
  • Amount: Cannot exceed the government’s annual guideline unless approved by the Landlord and Tenant Board (LTB).

It’s important to note that increases outside of these rules may not be legal. For a deeper look at rent increase rules and what tenants should expect, see Understanding Rent Increases: What Tenants Need to Know.

If you think a rent increase breaks these rules, collect your lease and any notices, and consider consulting the LTB or a local tenants’ clinic to review your options.

How Is the Rent Increase Guideline Set?

The annual rent increase guideline is calculated by the Ontario government and announced each year. For 2024, the guideline is capped at 2.5%[1]. This percentage tells landlords the maximum amount they can legally raise rent for most existing residential tenancies—unless they apply for an exception.

Most existing tenants are covered by the guideline, but newer buildings (first occupied after November 15, 2018) and some subsidized/non-profit units may be exempt from the guideline; verify your status in your lease or with a local tenant organization.

Exceptions to the Rent Guideline

  • New Buildings: Rental units first occupied after November 15, 2018 are exempt from the guideline but must still follow 12-month and 90-day notice rules.
  • Social and Affordable Housing: Different rules may apply to subsidized or non-profit units.

If you’re unsure about your unit’s status, check your lease or seek help from a tenant resource (see resources below).

Keep a copy of the notice, verify it is Form N1, and confirm the 90‑day window is met; if the notice is invalid, contact the landlord in writing or seek guidance from the LTB.

What Notice Must a Landlord Give for a Rent Increase?

Landlords must serve you with a written notice at least 90 days before the new rent takes effect. The required document is:

When to Use: Your landlord uses Form N1 to legally inform you of a rent increase that follows the annual guideline. For example, if you signed a lease on May 1, 2022, your landlord can’t increase your rent until after May 1, 2023, and must give you notice at least 90 days before the new rent starts.

If you can’t tell your unit’s status from the lease, ask a tenant clinic or ACTO for help interpreting the wording and whether your building qualifies for an exemption or guideline.

Always check that your rent increase notice is in writing, on Form N1, and delivered at least 90 days in advance. If you receive less notice or are given a verbal warning, you are not required to pay the increased rent.

Responding to an Incorrect or Illegal Rent Increase

If you believe your rent increase doesn’t follow the rules, you do not have to pay it. You can:

  • Contact your landlord in writing and refer to the correct rules.
  • Apply to the Landlord and Tenant Board (LTB) for review if the situation is not resolved.

The Landlord and Tenant Board (LTB) is Ontario’s official tribunal for resolving rental disputes.

To challenge a rent increase, you can use the following form:

When to Use: File Form T1 if your landlord charged a rent increase above the guideline or increased rent without proper notice.

What Happens at the End of Your Lease?

When your fixed-term lease ends, your tenancy automatically continues on a monthly basis unless you or your landlord give notice to end the agreement. You may wonder if rent can be raised when your lease renews. The rules for rent increases do not change at lease renewal—they still require one increase per 12 months and at least 90 days’ written notice.
