Last Month's Rent Deposit Rules in Ontario

Many tenants in Ontario have questions about paying a last month's rent deposit, what it covers, and whether landlords can keep it. This guide explains how last-month deposits work under Ontario rules, what landlords may legally require, and practical steps renters can take if there is a dispute. You will learn when a deposit counts as rent, what documentation to keep, how to request receipts and accounting, and how to apply to the Landlord and Tenant Board if needed. The language is plain and focused on tenant rights and responsibilities so you can act confidently when moving in, dealing with unpaid rent claims, or seeking return of funds at the end of tenancy.

How last-month rent deposits work in Ontario

In Ontario, a "last month's rent" deposit is treated as prepaid rent, not a separate security deposit for damage. A landlord may request a last-month rent deposit, but it is meant to be applied to the final month of tenancy. Keep records showing when you paid the deposit and any receipts you received so you can prove the payment was made and how it was used.

What landlords can and cannot do

Landlords may ask for a last month's rent deposit, but they cannot convert it into a damage-only security deposit or charge additional undisclosed fees. If a landlord uses the deposit during the tenancy to cover unpaid rent, they should provide an accounting showing the amounts applied and when. If you disagree about deductions or accounting, keep copies of all communications and receipts.

Documentation tenants should keep

• Collect and keep all receipts, bank records, and signed lease pages that show the deposit amount.
• Take dated photos of the unit when you move in and out to document condition.
• Ask the landlord for written accounting if they apply the deposit to unpaid rent or other charges.

When to dispute deposit use and how to proceed

If you disagree with a landlord about keeping the last month's rent deposit or how it was applied, start by asking for a written explanation and copies of any receipts or ledgers showing amounts deducted. Try to resolve the issue directly in writing; if that fails, you can apply to the Landlord and Tenant Board to have the matter decided.^[1]

Official forms and processes (what tenants use)

Useful official sources and forms are available from the Landlord and Tenant Board and Tribunals Ontario. Below are common forms tenants may use and when they apply.

• Form L1 — Application to Evict a Tenant for Non-Payment of Rent and to Collect Rent the Tenant Owes: used by landlords to collect unpaid rent but important to understand if your landlord claims unpaid rent against your deposit. Example: a landlord files an L1 claiming rent arrears that include amounts your deposit should have covered.
• Form L2 — Application to End a Tenancy and Evict a Tenant: used by landlords to seek termination, sometimes citing unpaid rent; tenants should review any eviction application and consider responding or seeking advice.
• Tenant applications via the LTB forms page — tenants use appropriate application forms when bringing disputes about deposits, unpaid rent, or accounting to the Board.

See the detailed forms and instructions on the Landlord and Tenant Board forms page for current application names and filing steps.^[3]

Moving out and getting your deposit applied or returned

When you move out, the last month's rent deposit should already have been applied to the final month's rent if that was the agreement. If the landlord claims additional charges or damages and wants to keep more, they must provide documentation.
