If you’re a tenant in Ontario and your landlord has raised your rent, it’s important to know whether the increase was legal. Not every rent hike is allowed under provincial law, and if an illegal rent increase is attempted, you have rights and resources to help you challenge it.

Understanding Legal and Illegal Rent Increases in Ontario

In Ontario, most rental units are covered by the Residential Tenancies Act, 2006^[1]. This law sets clear rules about when and how landlords can raise the rent. To be considered legal, a rent increase must:

• Follow the annual guideline set by the Ontario government (for 2024, the guideline is 2.5%).
• Be given with at least 90 days’ written notice before the new rent takes effect.
• Use the official Notice of Rent Increase Form (Form N1).
• Be at least 12 months after the last legal rent increase or move-in date.

Some exceptions exist, such as for units first occupied after November 15, 2018, or certain community or social housing. Always verify if your rental is covered by the Act.

What Makes a Rent Increase Illegal?

• The rent is raised above the annual guideline without special approval from the Landlord and Tenant Board (LTB).
• Your landlord doesn’t give you 90 days’ written notice using the proper form.
• The increase happens less than 12 months since your last rent hike or move-in date.

What to Do If You Receive an Illegal Rent Increase

If you suspect your rent increase is illegal, you are not required to pay the new amount. It’s important to act early and follow the right steps to protect yourself while maintaining your tenancy in good standing.

Step 1: Review Your Rent Increase Notice

• Check if your landlord used the official Notice of Rent Increase (Form N1). The document must clearly state current rent, new rent, and the date the increase starts.
  • Official form: Form N1 – Notice of Rent Increase
• Ensure you received the notice at least 90 days in advance and that it’s been at least 12 months since your last increase.

Step 2: Responding to the Notice

• If the notice is incorrect or the increase is over the guideline, you can refuse to pay the new rent.
• Keep detailed records and all communication with your landlord.
• If you make a payment at the increased rate, it could be seen as accepting the new rent—respond quickly!

Step 3: Contact Your Landlord in Writing

Politely let your landlord know—ideally in writing—that the rent increase is not valid according to Ontario law. Include references to the Residential Tenancies Act. This may resolve the issue without further action.

Step 4: Apply to the Landlord and Tenant Board (LTB)

If the issue isn’t resolved, you can apply to the Landlord and Tenant Board (LTB Ontario), which is the tribunal that handles rental disputes. The correct form for challenging an illegal rent increase is:

• Form T1: Tenant Application for a Rebate of Money the Landlord Owes
  Download Form T1 – Tenant Application for a Rebate

Use Form T1 if you have already paid the higher rent and want that money back. If you haven’t paid, you can still use the application to clarify your rights and prevent eviction proceedings.

What Happens at the Hearing?

The LTB will schedule a hearing where both you and your landlord can provide evidence. You can represent yourself or have someone come with you. If the LTB agrees with you, they can order your landlord to repay any overcharged rent and ensure your rent is adjusted to the legal amount.

Action Checklist for Tenants

• Confirm your unit is governed by the Residential Tenancies Act
• Double-check the amount and timing of the rent increase against provincial guidelines
• Keep all documents and correspondence
• Apply to the LTB if you can’t resolve the issue directly
• For more details on your general obligations and protections, review Tenant Rights in Ontario
