If you’re a tenant in Ontario and have recently received notice of a rent increase, you might be wondering what your rights are and what you can do if you believe the increase is unfair or not allowed. Understanding the laws around rent increases in Ontario can help you protect your home and budget. In this guide, we cover the essential steps to dispute a rent increase, explain official forms and processes, and share supportive resources for Ontario tenants.

Your Rights When Facing a Rent Increase in Ontario

In Ontario, most tenants are protected under the Residential Tenancies Act, 2006^[1]. This law sets strict rules for how and when landlords can raise your rent. Generally, your landlord must:

• Give you at least 90 days' written notice before the increase takes effect
• Use the approved government form (N1: Notice of Rent Increase)
• Increase rent only once every 12 months
• Follow the annual rent increase guidelines set by the province (exceptions exist, such as for newer buildings)

If a landlord fails to follow these steps, you may have a valid reason to dispute the increase.

When is a Rent Increase Allowed?

Most Ontario rentals are subject to a government-approved rent increase guideline. For 2024, the guideline is 2.5%. Some exceptions apply, including certain new buildings and units exempt from rent control.

How to Dispute a Rent Increase Step-by-Step

If you believe your rent increase is too high or was not given properly, here’s what you can do:

• Check the notice: Did you receive an official N1 form from your landlord?
• Review the amount: Is the increase above the guideline or happening less than 12 months since the last one?
• Confirm the notice period: Were you given at least 90 days’ advance notice?

If any rule wasn’t followed, you may dispute the increase through the Landlord and Tenant Board (LTB). This independent tribunal resolves tenancy disagreements in Ontario.

Key Official Form: Landlord and Tenant Board T1 Application

• Name: T1 – Tenant Application for a Rebate of Money the Landlord Owes
• Purpose: Tenants use this form to ask for a rent rebate if their landlord charged more than legally allowed—such as an unlawful rent increase
• When to Use: If you paid an illegal increase or your landlord did not follow proper notice procedure
• Where to File: Submit to the Landlord and Tenant Board’s official T1 form page

Example: If your landlord raised the rent by 4% without sending the official N1 Notice or giving 90 days’ notice, you can file the T1 form with the LTB. Supporting documents such as your lease, payment history, and a copy of the rent increase notice will strengthen your application.

If you’re unsure about any part of the process, seek support from tenant help lines or legal clinics listed below. Acting quickly is important: You have up to a year from the date the unlawful rent was paid to file your T1.

Other Important Considerations

If your tenancy recently renewed or changed, it’s helpful to understand the rights you gain after signing a new agreement. See What Tenants Need to Know After Signing the Rental Agreement for further details on your ongoing protections.

What to Expect at the Landlord and Tenant Board

The LTB handles disputes between tenants and landlords in Ontario. Your application may lead to mediation or a hearing. Typical outcomes can include a refund of overpaid rent or a ruling invalidating an unlawful increase.

1. Can my landlord increase the rent by any amount they want?
   Landlords can only raise rent once every 12 months, following the government’s annual guideline unless your unit is exempt. Excessive or improper increases can be disputed.
2. What if I already paid the higher rent?
   You may apply for a rebate by submitting the T1 application to the Landlord and Tenant Board if the increase was unlawful.
3. Do I have to move out if I disagree with a rent increase?
   No. You have the right to stay and dispute the increase through the LTB without risking eviction solely for contesting the increase.
4. What notice must my landlord give for a rent increase?
   Your landlord must provide written notice using the N1 form at least 90 days before the new rent takes effect.
5. Where can I get help if I need advice on disputing a rent increase?
   Government-run tenant support lines, legal clinics, and advocacy organizations listed below can help guide you through the process.

Conclusion: Key Points for Ontario Tenants

• You are protected by Ontario’s Residential Tenancies Act, which limits rent increases and sets required notice periods.
• If your rent increase is not properly issued or above the guideline, you can dispute it through the LTB using the T1 form.
• Stay informed, keep documentation, and seek support if needed—your rights are there to help you maintain stable housing.

Disputing a rent increase can feel daunting, but following official steps ensures your concerns are heard and addressed fairly.
