Avoiding Common Mistakes with Tenant Rights in Ontario

Understanding your rights and responsibilities as a tenant in Ontario is vital to maintaining a positive renting experience. Many disputes and costly mistakes can be avoided simply by knowing what the law expects from tenants, and where the most common pitfalls occur. Whether you're renting for the first time or have years of experience, Ontario's rental laws—governed by the Residential Tenancies Act, 2006—set out clear guidelines to help tenants live safely and confidently.

Top Mistakes Tenants Make with Their Rights and Responsibilities

1. Not Reviewing the Rental Agreement Thoroughly

Many tenants sign their lease in a hurry, overlooking important clauses and rules that impact their tenancy. Every rental agreement should clearly state the rent amount, payment schedule, included utilities, and conditions about things like subletting or pets.

After signing, it's crucial to know exactly what you agreed to. For more, check What Tenants Need to Know After Signing the Rental Agreement.

2. Mishandling Rental Deposits and Payments

Ontario restricts what kind of deposits landlords can collect—usually just first and last month's rent. Damage or "key" deposits are generally not permitted. Misunderstanding deposit rules can lead to disputes or lost money.

3. Ignoring Health, Safety & Maintenance Issues

It's a common mistake to defer reporting problems like broken appliances, leaks, or unsafe living conditions. Ontario law requires landlords to keep the rental unit in good repair, but tenants must report issues promptly. Doing so in writing helps create a record if there's a dispute later.

4. Missing or Improper Written Notices

Notice is a key legal requirement for many tenant actions—ending your lease, requesting repairs, or contesting rent increases. Verbal requests may not count. Use official forms and get proof of delivery whenever possible.

5. Not Understanding the Rules Around Ending a Tenancy

Leaving a rental before the end of your lease, or without proper notice, can result in claims for unpaid rent or lost deposit. Ontario tenants usually must give at least 60 days’ written notice before moving out at the end of a lease or during a month-to-month tenancy.

Forms Every Ontario Tenant Should Know

  • N9 – Tenant's Notice to End the Tenancy: Use this form to give notice when you plan to move out. It should be submitted at least 60 days before your intended move-out date.

  • T2 – Application About Tenant Rights: Submit this application to the Landlord and Tenant Board (LTB) if your landlord isn't meeting legal obligations, such as making repairs or respecting your privacy.

  • T6 – Tenant Application About Maintenance: Use this application to address issues like neglected repairs or health and safety concerns in your unit.

Remember: If your situation becomes overwhelming, contact the Landlord and Tenant Board or a tenants' association for help before small mistakes escalate.

Where to Turn for Disputes

Disagreements are sometimes unavoidable. In Ontario, the official tribunal for resolving landlord-tenant disputes is the Landlord and Tenant Board (LTB). They provide hearings, mediation, and enforce the Residential Tenancies Act, 2006[1].

  1. What if repairs aren't made when I report them?
    You can apply to the LTB using Form T6 (Tenant Application About Maintenance). This may result in an order for repairs or compensation. Always keep written records of your repair requests.
  2. Can my landlord ask for a damage or pet deposit?
    In Ontario, landlords can only collect a rent deposit (first and/or last month) and, in some cases, a key deposit (if it's refundable and no higher than the cost of replacement). Damage deposits are not allowed.
  3. How much notice do I need to give to end my lease?
    Tenants must typically provide 60 days’ written notice using Form N9. The notice should line up with the end of a rental period unless otherwise stated in your lease.
  4. What can I do if my landlord wants to evict me without cause?
    Your landlord must follow specific procedures and, in most cases, have a valid legal reason as set out in the Residential Tenancies Act. Keep all written notices and contact the LTB for support if you receive an eviction notice.
  5. Where can I find more details about my rights?
    Start with Tenant Rights in Ontario and refer to official resources provided below for government-backed information.
  1. How do I submit a maintenance complaint?
    First, inform your landlord in writing and give them reasonable time to respond. If there's no action, complete and file Form T6 (Tenant Application About Maintenance) with the LTB, attaching copies of your communications and any relevant photos or documentation.
  2. How can I give notice to move out properly?
    Fill out Form N9 (Tenant’s Notice to End the Tenancy)—stating your final day and ensuring it matches your rental period. Deliver the form to your landlord, keeping a copy for your records.
  3. How to respond to a rent increase notice?
    Review the notice carefully to ensure it meets legal requirements (minimum 90 days' written notice; follows provincial guidelines on amount and timing). If you believe the increase is above the legal limit, you can file a dispute with the Landlord and Tenant Board.
  • Always carefully read your lease and official notices. Ask for clarification if anything is unclear.
  • Provide written records for maintenance issues, payments, and communication with your landlord.
  • Use official forms and submit them within designated timelines to protect your tenancy.
