Rent Deposits vs Security Deposits: Ontario Tenant Rights Explained

Maintenance & Repairs Ontario 5 min read · published March 09, 2026 Flag of Ontario

Understanding what your landlord can and cannot ask for when you rent a new place is crucial for protecting your rights as a tenant in Ontario. Many tenants are unsure about rent deposits, security deposits, and the rules landlords must follow. This article explains the legal differences, what’s permitted under Ontario law, what to do if your landlord requests a prohibited deposit, and where to turn if you need help.

What is a Rent Deposit in Ontario?

In Ontario, a rent deposit is a payment required by a landlord, usually at the start of a tenancy, to be applied to your last month’s rent – not the first. This is sometimes called a "last month's rent deposit" or LMR. By law, your landlord can ask for this deposit before you move in, but only up to the amount of one month’s rent (or one week’s rent for weekly tenancies).

  • The deposit must NEVER be applied to damages, repairs, or cleaning.
  • Your landlord must pay you interest on the deposit each year, at the guideline rate set by the province.
  • You cannot use your rent deposit as payment for any month except the last one, unless your landlord agrees in writing.
The annual interest rate for rent deposits is typically equal to Ontario's rent increase guideline (e.g., 2.5% in 2023). Landlords must either pay this interest annually or let you deduct it from a future rent payment.

Is a Security Deposit Legal in Ontario?

Security deposits—money held to cover potential damage, cleaning, or key loss—are illegal in Ontario rental housing. Landlords cannot require an additional deposit to cover damages or extra costs, with the only exception being a refundable key deposit. Even then, the key deposit amount must not be more than the cost of replacing the key itself.

  • If your landlord asks for a security deposit (for furniture, cleaning, or repairs), you may refuse and point out that it’s not allowed under the Residential Tenancies Act, 2006.
  • Any other deposit, such as for "pet cleaning" or "damage," is not allowed.
If pressured to pay an illegal deposit, take screenshots of ads or save written requests as evidence. Many tenants successfully recover prohibited deposits through the LTB using these records.

What to Do If a Landlord Requests a Prohibited Deposit

If a landlord asks for a security deposit or any type of deposit not permitted by Ontario law, you should:

  • Politely inform the landlord that Ontario’s Residential Tenancies Act, 2006 does not allow this type of deposit.
  • If pressure continues, keep written records of your communications.
  • You do not have to pay illegal deposits to secure the rental.
  • If an illegal deposit is already paid, you can apply to the Landlord and Tenant Board for its return.
Tip: Before signing any lease or paying a deposit, always read the terms carefully and ask questions if any fees or deposits seem unusual.

Official Forms and How to Use Them

  • Application about Tenant Rights (Form T2): If your landlord collects an illegal deposit, use this form to apply to the Landlord and Tenant Board (LTB) for a remedy (e.g., order to return the deposit or compensation). Download Form T2 from the official LTB forms page.
    Example: You paid a $500 "damage deposit" and want it refunded after your landlord refuses to return it.
  • Tenant Application (Form T1): If your landlord has not paid interest on your last month’s rent deposit, use Form T1 to apply for compensation. Available at the LTB's official site.
When filing LTB forms, include copies of your lease, deposit receipts, and any communication about the deposit. The Board typically processes cases within 2-4 months.

Filing these forms helps protect your rights and can get you back money you're owed.

Key Differences Summarized

  • Rent Deposits: Can only be the last month’s rent or week’s rent deposit. Must be applied to the final period of the tenancy and accrue interest annually.
  • Security Deposits: Not allowed, except for a key deposit equal to the key replacement cost.

Landlords may not use deposits for maintenance or repair costs. If you've experienced issues related to repairs or cleanliness, the proper way for landlords to address these is through a claim at the LTB—not by demanding deposits up front.
