Ontario Rent Increase Rules and Fines: Tenant Guide

Landlord Compliance & Penalties Ontario 5 min read · published March 09, 2026 Flag of Ontario

Are you a tenant in Ontario and worried about how much your landlord can increase your rent? Knowing the rules for rent increases and when fines or penalties apply can help you protect your budget and your rights. Let’s break down Ontario’s rent increase regulations, legal forms, and what to do if your landlord doesn’t follow the law.

Most private rentals fall under these rent-increase rules, but some new units and certain social housing may be exempt. Check your tenancy start date and unit type to confirm whether the guideline applies to you.

How Rent Increases Work in Ontario

Ontario’s rent increase rules are set by the Residential Tenancies Act, 2006 (RTA). Most rental units are covered by these laws, which set maximum limits and procedures for annual rent increases. The guideline applies to most private residential units, though some new units and certain social housing may be exempt.

  • Guideline Increases: Each year, Ontario sets a rent increase guideline — the maximum percentage landlords may raise rent without special approval. For 2024, the guideline is 2.5%.[1]
  • 12-Month Rule: Your landlord can only raise your rent once every 12 months.
  • 90 Days’ Written Notice: They must give you at least 90 days’ advance written notice before the increase begins.

Some units, such as newly occupied rental buildings after November 15, 2018, may not be rent controlled. Always check if your unit type is covered by the guideline.

Landlord Compliance: What Happens if the Rules Aren't Followed?

Your landlord must strictly follow Ontario’s rent increase requirements. If they raise your rent without proper notice or above the allowed percentage, the increase is illegal, and you are not required to pay the extra amount.

  • Unlawful increases can be ordered repaid to tenants by the Landlord and Tenant Board of Ontario.
  • If you have already paid an illegal increase, you can apply to the Board for a rebate and possible compensation.
  • Landlords who violate these rules may also face administrative penalties and, in some cases, fines.[2]
Tip: If you receive a rent increase notice you believe is unlawful, do not simply refuse payment. Instead, seek help or file an application with the Board to resolve the issue and keep records of all communications.
If you receive an increase you believe is unlawful, do not pay the extra amount. Instead, contact the Board or a legal clinic for guidance and start documenting all communications with your landlord.

Challenging an Illegal Rent Increase: What to Do

If you think your rent has risen illegally, you can apply to the Landlord and Tenant Board for help.

  • Application: Use Form T1 – Tenant Application for a Rebate
  • How It Works: Submit this form if your landlord has overcharged you for rent or charged unlawful increases.
  • Download Form T1 – Official Source

The Board will review your case, and may order your landlord to repay any illegal rent increases, plus interest. They can also issue fines for persistent or serious breaches.

Penalties and Fines: Holding Landlords Accountable

Landlords who repeatedly breach rent increase rules, or deliberately mislead or pressure tenants, may be subject to financial penalties under Section 233 of the Residential Tenancies Act. Fines can reach up to:

  • $50,000 for individuals (landlords)
  • $250,000 for corporations

These are maximum penalties; fines are set by the courts based on severity, intent, and impact on tenants.[3]

Important nuance: penalties are maximums, and the actual amount is determined by the court based on factors like severity and intent. A court may also order rebates or ongoing compliance measures in addition to monetary fines.

Special Rent Increase Situations

In limited circumstances, landlords can apply for a rent increase above the guideline (called an "Above Guideline Increase" or AGI). This is only allowed for very specific reasons (e.g., major repairs, increased taxes, security services) and must be approved by the Board. Landlords use a different application and must provide supporting evidence. Tenants are always notified and have the right to participate in a Board hearing.
