This guide explains the Residential Tenancies Act, 2006 rules that apply to last month's rent deposits in Ontario, practical steps tenants can take if a landlord withholds funds, and which official forms and tribunal processes to use. It also covers receipts, interest, and documentation tips so tenants understand their rights and responsibilities when paying or recovering a deposit. Use the action steps and links below to find forms, contact the Landlord and Tenant Board, and prepare a dispute if needed.

What Ontario law says

Ontario’s legislation governing residential tenancies is the Residential Tenancies Act, 2006[1]. The Landlord and Tenant Board (LTB) is the tribunal that handles disputes about rent deposits and other tenancy issues; see the Board’s main site at Landlord and Tenant Board[2]. The LTB site also publishes the official application forms and guides tenants use to start a claim[3].

In most cases Ontario landlords may only collect a rent deposit to be applied as last months rent.

Key rules for last month's rent deposits

  • A landlord may collect a deposit to be applied as last months rent; it is treated as prepaid rent and not a separate damage security deposit.
  • Landlords cannot require a separate security deposit for damage from most residential tenants; the deposit should not be held as a damage bond.
  • Always ask for and keep a written receipt when you pay any deposit, and keep records of payments, communications, and move-in condition photos.
  • If a landlord withholds the deposit at the end of tenancy, you can ask for an explanation in writing and may need to file an application with the Landlord and Tenant Board.
Keep all payment receipts and dated photos of the unit at move-in and move-out.

Paying and applying last month's rent

If you pay a deposit intended as last months rent, the landlord should apply it to your final months rent when you vacate (unless you owe rent for an earlier month). If the landlord claims deductions for unpaid rent or damage, they must provide a clear breakdown and evidence.

When you should get a refund or payment back

  • If the deposit is an overpayment or the tenancy ends earlier than planned, request the balance in writing and give the landlord a reasonable time to respond.
  • If a landlord refuses or ignores your written request, you can file an application with the LTB asking for the deposit plus any applicable interest or damages.
Respond to any written notices and keep copies; missed deadlines can affect your ability to recover money.

How to prepare if you must dispute a deposit

Good evidence and a clear timeline make disputes easier. Collect receipts, bank records, photos of the unit, and any messages or emails about the deposit. If you are moving out and expecting a refund, compare your final condition photos to the move-in photos and note any legitimate wear and tear versus damage.

FAQ

Can a landlord require a damage deposit in Ontario?
No. For most residential tenancies in Ontario landlords may not require a separate damage deposit; they may request a rent deposit applied to the last months rent instead.

Interest rules can change; check the Residential Tenancies Act, 2006 and LTB guidance for current requirements and how interest is calculated.
What should I do if my landlord keeps part of my deposit unfairly?
Request a written explanation, collect all evidence, and if unresolved file an application with the Landlord and Tenant Board to ask for the funds back.

How-To
