Rent & Deposits Ontario 3 min read · published March 09, 2026 Flag of Ontario

As a tenant in Ontario, navigating the complexities of rent increases can be challenging. This often involves understanding your rights under the Residential Tenancies Act, 2006 and knowing the correct steps to take when faced with an unexpected rent hike. Let's explore how you can manage rent increase problems effectively, ensuring you're protected and informed every step of the way.

Rent increases must be served with at least 90 days' written notice and must follow the government’s annual guideline. Keep a dated copy of the notice and note the effective date in case you need to challenge it.

Understanding the Basics of Rent Increases

In Ontario, rent increases are governed by the Residential Tenancies Act, 2006, which sets out guidelines for landlords regarding when and how they can increase rent. Generally, landlords must give tenants at least 90 days' written notice before a rent increase, and the amount must comply with the annual rent increase guideline set by the government.

Checking the Legality of Rent Increases

  • Ensure the increase follows the annual rent guideline published by the Ontario government.
  • Check if your rental unit is exempt from the guideline, for instance, if it's a newly built or converted residential space.
  • Verify that you’ve received the legal 90 days notice before the new rent takes effect.

Exemptions can apply for newly built or converted units, but exemptions are limited. If you think your unit fits an exemption, verify with the LTB or official guidance before assuming the guideline doesn’t apply.

Your Rights and Options

If you believe the rent increase is unlawful, it's crucial to understand your rights and options as a tenant. You can contest the increase by applying to the Landlord and Tenant Board (LTB) in Ontario, which is the official body that resolves disputes between landlords and tenants.

Caution: If you decide to challenge, act quickly to meet any filing deadlines. Gather your lease, the rent increase notice, and any landlord correspondence for the LTB filing.

Before proceeding, ensure you have gathered all relevant documentation such as your lease agreement, the notice of rent increase, and any correspondence with your landlord.

Insight: Keep a clear timeline of events—dates of notices, conversations, and submissions—to help present a coherent case at a hearing.

Action Steps for Contesting a Rent Increase

File a Tenant Application

If you decide to challenge the rent increase, you will need to file a Tenant Application for a Rent Reduction Form (Form T6). Here’s how:

  1. Download the Form T6: This form is available on the Landlord and Tenant Board's website. Ensure you have the latest version for accuracy.
  2. Complete the Form: Provide details about the increase and why you believe it's invalid.
  3. Submit the Form: File the completed form with the LTB either online, by mail, or in person.

Keep copies of all documents for your records, and ensure you meet any deadlines specified by the LTB.

Example: If the notice claims a higher amount than the guideline, document the discrepancy and bring both the notice and your lease to the hearing to illustrate the gap.

    Verify the compliance of the notice with Ontario guidelines and, if necessary, file a formal objection with the Landlord and Tenant Board.
  2. How can I ensure my rent increase notice is legitimate?
    Check that it provides at least 90 days' notice and confirms the increase adheres to the annual rent-guideline.
  3. Are there specific cases where the rent increase guidelines don’t apply?
    Yes, new residential spaces like condos or units built after November 15, 2018, may be exempt from rent guidelines.
