Rent increases are a common concern for tenants in Ontario, especially in a competitive rental market. While landlords have the legal right to increase rent, there are strict rules they must follow under the Residential Tenancies Act (RTA). If your rent is going up, it’s important to understand your rights, verify if the increase is legal, and know how to dispute an unfair rent hike.

This guide covers how rent increases work in Ontario, when you can challenge an increase, and how to dispute unlawful rent hikes.

1. How Rent Increases Work in Ontario

📌 In most cases, landlords can only increase rent once per year and must follow rent control laws.

✅ Key rules for rent increases:

• Landlords must give 90 days’ written notice before increasing rent.
• The increase cannot exceed the guideline set by the Ontario government (unless an exemption applies).
• Rent can only be raised once every 12 months.

🚨 If a landlord raises rent illegally, you are NOT required to pay the increase.

For more details, check Ontario’s Rent Increase Guidelines.

2. What Is the Rent Increase Guideline for 2024?

Each year, the Ontario government sets a maximum allowable rent increase for most rental units.

📌 For 2024, the rent increase guideline is 2.5%.

✅ This means landlords can only increase rent by up to 2.5% in most cases.

🚨 Exceptions:

• Some buildings are exempt from rent control (e.g., new buildings occupied after Nov 15, 2018).
• A landlord can apply for a higher increase due to major repairs or increased costs (Above Guideline Increase – AGI).

3. When Can You Legally Challenge a Rent Increase?

You can dispute a rent increase if the landlord did not follow legal requirements.

📌 Reasons to dispute a rent increase:✅ The increase is higher than the guideline and no AGI approval was granted.✅ You did not receive 90 days’ written notice.✅ The increase was applied less than 12 months after the last one.✅ Your rental unit is covered by rent control laws but the landlord is charging more than allowed.

🚨 If any of these apply, you can refuse to pay the increase and file a dispute.

• Commercial or mixed-use properties where the rental unit is not the primary use.
