Ontario Last Month's Rent Deposit Rules

Many tenants in Ontario wonder what a "last month" rent deposit is, when a landlord can ask for it, and how it can legally be used. This plain-language guide explains the common rules tenants should know about deposits collected for the last month of tenancy, how to document payments and receipts, what landlords may deduct or apply the payment to, and practical steps if a dispute arises. It is written for renters and covers when to keep records, when to ask for receipts, and how to bring a problem to the Landlord and Tenant Board so you can protect your rights in Ontario.

What is a last month's rent deposit?

A last month's rent deposit is a prepaid amount intended to cover the final month of rent at the end of a tenancy. In Ontario this deposit functions as prepaid rent rather than a security deposit, and it is governed by provincial tenancy rules and the Residential Tenancies Act, 2006 ^[2]. The Landlord and Tenant Board hears disputes about how deposits are used and about unpaid rent or deductions ^[1].

How much can a landlord collect and when?

• Landlords may generally request payment equal to one month's rent for the last month of a monthly tenancy.
• That payment is usually collected when the tenancy begins or when the tenant switches to a monthly tenancy, and should be documented in your lease or written agreement.
• Landlords cannot require extra "damage" or "security" deposits beyond the lawful last month's rent payment as a condition of tenancy.

How can a landlord use the last month's rent deposit?

• The deposit can be applied to pay the tenant's last month of rent when the tenancy ends.
• If the tenant owes rent for earlier months when the tenancy ends, a landlord may seek unpaid rent; they may ask you to apply the deposit toward unpaid rent but they cannot double-charge the same month.
• If a landlord seeks to keep the deposit for damage or other losses, they generally must apply to the Landlord and Tenant Board to resolve the claim rather than unilaterally convert the deposit to compensation.

Documenting payments: receipts and proof

Keep a paper or digital receipt for any last-month payment and timestamped photos, text messages, or email confirmations of the agreement. If your lease mentions a last month's deposit, keep a copy of that page. Records are the strongest evidence if a dispute goes to the Landlord and Tenant Board ^[1].

• Always ask for a dated receipt specifying the amount and that it is for "last month's rent."
• Keep a clear photo log of the unit's condition on move-in and before move-out to refute improper damage claims.
• If a landlord refuses to provide a receipt, send a short written request (email or text) asking for one so there is a record.

What to do if the landlord misapplies the deposit

If a landlord uses the deposit in a way you believe is improper—such as keeping it without an accounting or charging it for damage without proof—you should first ask for a written explanation and copies of receipts or invoices. If that does not resolve the issue, you can file an application with the Landlord and Tenant Board to recover unpaid rent or compensation and to resolve disputes over the deposit ^[1]. The LTB website and its forms explain the exact process and what evidence to attach ^[3].

Practical tenant steps before filing a board application

1. Check your written lease or rental agreement to confirm any clause about last months payment and how it should be applied.
2. Gather receipts, bank records, photos, texts, and emails that show payment and the unit condition.
3. Request a written accounting from the landlord showing how they applied the deposit.
4. Try a calm, documented mediation or settlement request in writing before filing an application.
5. If unresolved, file an application with the Landlord and Tenant Board and attach your evidence.
