Rent & Deposits Ontario published July 01, 2025 Flag of Ontario

If you’re renting in Ontario and facing issues with your landlord over rent payments, security deposits, or getting your money back, it’s important to understand your legal rights and know the steps you can take for resolution. Whether it’s a disagreement over how much rent is owed, questions about legal rent increases, or trouble getting your deposit returned, Ontario offers clear resources to help tenants navigate these disputes. This guide covers the support available to you and how to take action under Ontario laws.

Understanding Your Rights in Rent and Deposit Disputes

Rent and deposit disagreements between tenants and landlords are common. Ontario law, specifically the Residential Tenancies Act, 2006[1], outlines rights for both parties. The key principles are:

  • The amount of rent can only be increased once every 12 months, and only by legal notice
  • Security deposits can only be collected as a rent deposit, not for damages
  • You have the right to a written explanation of any deductions from your deposit
  • Any dispute can be brought to the Landlord and Tenant Board (LTB) for a fair hearing

Knowing what you paid, your obligations, and the law can help protect you during a dispute.

Common Rent & Deposit Issues and Where to Find Legal Support

  • Receiving notice of a rent increase that seems too high
  • Being refused the return of your rent deposit when moving out
  • Disagreements about non-payment of rent or late fees

If you face any of these, review your lease and receipts first. For a full overview of deposit rules in Ontario, visit Understanding Rental Deposits: What Tenants Need to Know. For payment guidance and documentation tips, check Tenant's Guide to Paying Rent: Rights, Responsibilities, and Tips.

Getting Help: The Landlord and Tenant Board

Most rent and deposit disputes in Ontario are handled by the Landlord and Tenant Board (LTB), a tribunal that mediates and resolves issues between tenants and landlords. You can apply directly to the LTB for issues like:

  • Unlawful rent increases
  • Withholding your deposit
  • Non-payment of rent allegations

Once you apply, the LTB will schedule a hearing or mediation to help resolve the issue fairly. Always check that your landlord followed required notice periods and proper documentation as outlined in the Tenant Rights in Ontario resource.

Essential Official Forms for Ontario Tenants

There are official forms to start or respond to a dispute. Here are the most commonly used for rent and deposit issues:

  • Form T1: Tenant Application for a Rebate of Money
    • When to use: If your landlord collected illegal charges (like extra deposits) or charged more than the law allows.
    • How to use: Gather receipts, fill out Form T1, and submit it to the Landlord and Tenant Board.
  • Form T2: Application About Tenant Rights
    • When to use: If your landlord isn’t returning your deposit or is violating your rights.
    • How to use: Complete the Form T2 and file with relevant supporting evidence.
  • Form L1: Application to Evict a Tenant for Non-payment of Rent
    • Note: If you receive an L1 notice from your landlord, you may respond with evidence or apply for relief.
    • Guidance is available from the LTB’s official forms page.

Act quickly if you need to submit or respond to a form, as deadlines are strict.

Do You Need Legal Advice?

While you don’t need a lawyer to file with the LTB, legal clinics and tenant advocacy groups in Ontario can provide support, especially for low-income renters. The Legal Aid Ontario Community Legal Clinics often handle rental disputes and can help you prepare your case or fill out forms.

Alternative Steps: Communication and Evidence

Before applying to the LTB, document all communication with your landlord. Whenever possible:

  • Ask for everything in writing
  • Keep all payment records and receipts
  • Save copies of notices, emails, or texts about rent or deposits
If you and your landlord resolve the issue, you may not need a formal LTB hearing. Many disputes settle through clear, respectful communication first.
