Key Takeaways
- Ontario allows landlords to collect a rent deposit equal to one month’s rent, strictly for last month’s rent, and prohibits using it as a traditional security or damage deposit.
- Landlords must pay annual interest on rent deposits at the provincial rent increase guideline rate, either directly to the tenant or by applying it toward rent deposit top-ups after rent increases.
- Rent deposits are not refundable because they are applied to the final month’s rent, but landlords must provide receipts and transfer responsibility to the new owner if the property is sold.
- Failing to comply with Ontario rent deposit laws can result in Landlord and Tenant Board penalties, including interest repayment, refunds, and fines for ongoing violations.
If you’re renting out a property in Ontario, then it’s imperative to familiarize yourself with the applicable rent deposit rules. This way, you’ll be able to stay legally compliant, and help build a solid relationship with your residents. Here is a guide by CMG Toronto Property Management on what a rent deposit is, how much you can charge, when to return it, and everything in between.
A Guide to Ontario’s Rent Deposit Law
In Ontario, rent deposit rules are contained under both the Landlord and Tenant Board (LTB) and the Residential Tenancies Act (RTA). A rent deposit is also referred to as last month’s rent. Its primary purpose is to ensure you get paid for the very last month the resident occupies the unit.

As a landlord, you can require it as part of the initial move-in costs. However, if you do, there are certain rules you must follow to stay legally compliant. Here are some answers to commonly asked questions:
How Much Can Landlords in Ontario Charge as a Rent Deposit?
In the Province of Ontario, landlords cannot require rent deposits exceeding one month’s rent. Suppose, for instance, that the monthly rent for a rental unit is $2,000. In such a case, the rent deposit must not exceed $2,000.
This is unlike a traditional security deposit that is meant to provide the landlord with a financial cushion against certain potential issues such as, unpaid rent, unpaid utilities, professional cleaning service, and/or damage exceeding normal wear and tear.
How Must Landlords Hold Residents’ Rent Deposits in Ontario?
Landlords in Ontario can store the deposit several ways including in an interest-bearing account. To know how much interest is payable to a resident, you’ll need to check the Ontario rent increase guidelines.
For 2026, for instance, the rent increase guideline is 2.1%. This is the maximum amount you can increase the rent by for the year. And resultantly, you need to pay the same percentage as interest on the deposit.
You can pay the interest accrued either directly to the resident or add it to the rent deposit to keep up with any rent raises. The interest is due annually to the resident.

The interest payment is meant to compensate the resident for the duration of time the landlord was holding the funds. If you fail to make the payment, the resident can have the option of seeking a rebate or making appropriate deductions from future rent payments.
Do Landlords have to Provide Their Residents with a Rent Receipt?
Yes, once you receive a rent deposit from a resident, you must provide them with a payment receipt. This will ensure that both you and the resident have proof of payments.
Can Landlords Withhold Rent Deposits from Ontario Residents?
Rent deposits are not refundable because, unlike a traditional security deposit, they’re only meant to cover last month’s rent. That said, a landlord wouldn’t be able to change both last month’s rent and rent deposit.
What Happens if the Property Ownership Changes Hands?
In case the property ownership changes hands, the incoming landlord assumes all responsibilities under the Ontario rent deposit and landlord-tenant laws.
Also, it’s the new landlord’s duty to obtain all relevant information from the outgoing landlord. This should help minimize potential conflicts or misunderstandings regarding the handling and return of the deposit.
What is the Ontario Deposit Law Return Deadline?
Unlike with a traditional security deposit, there is no deadline for a rent deposit’s return. This is because it is meant to cover last month’s rent.

If you had also collected a key deposit, then you’ll need to refund it when the lease ends. After the resident returns the keys, you must refund the deposit to the resident.
What are the Penalties for Violating Rent Deposit Laws?
If you fail to uphold your responsibilities are under the Ontario security deposit law, you may be liable to certain penalties under the Landlord Tenant Board. They can include returning a full refund, paying due interest payments, and in some cases, a fine of up to $1,000 a day for continued non-compliance.
