Ontario LTB Form T1: Get Back Money a Landlord Owes
Know when this application applies, how to fill it out, what to attach and what happens next.
Form T1 asks the Landlord and Tenant Board to order repayment of money a landlord should not have kept. It can cover illegal rent or charges, unpaid last-month-rent deposit interest, retained deposits, unpaid N12/N13 compensation and other listed grounds. You must choose a specific T1 reason; it is not a general complaint form.
This guide explains the official application, but does not submit it. Confirm case-specific filing requirements before acting.
Which T1 reason fits your problem?
- Reason 1 or 2: you paid illegal rent or a prohibited fee (such as illegal key money).
- Reason 3 or 4: your last-month deposit was wrongly kept, or you paid a deposit but were not allowed to move in.
- Reason 5: the landlord did not pay interest owing on the last-month rent deposit.
- Reason 6: required N12/N13 compensation was not paid.
- Reason 7 or 8: proceeds from sold property were withheld, or the landlord failed to provide required rent-increase-prohibition information.
Most payment-related T1 reasons have a 12-month look-back or application limit, measured as specified for that particular reason. Choose the reason before calculating your deadline. A prospective tenant can use only limited reasons (such as certain illegal charges or unreturned deposits).
How to complete T1
- Part 1 — parties and address: fill in the rental unit and the landlord's correct legal name. Include additional people on the Schedule of Parties when necessary.
- Part 2 — select reason(s): check only the numbered reasons that match the payment problem. For each, state the amount, date, who received the money and why it was unlawful or repayable.
- Rent history: for an illegal-rent claim, list rent charged over the past 12 months (or since moving in if shorter) and dates of any changes; do not skip the table.
- Calculation: show how you arrived at each requested rebate, and attach a separate calculation if the form box is too small.
- Part 3: sign and date. Attach rent receipts, deposit records, N12/N13 notice, bank statements or correspondence supporting the selected reasons.
Worked example: illegal fee
A tenant paid a $150 “move-in administration” charge on April 5, 2026, and has an e-transfer receipt. The tenant selects T1 Reason 2, records April 5, who received $150, and explains why the charge is prohibited. They request $150 and attach the receipt. The LTB decides whether the fee is illegal; the payment alone does not guarantee a rebate.
What happens after filing?
Pay the current fee, file T1 through the Tribunals Ontario Portal if available for your application, or use an accepted alternative method. The LTB may schedule a hearing, where you must prove both the legal reason and the amount. T1 does not replace T2 for harassment or illegal entry, or T6 for repairs and maintenance.
Avoid this mistake
Do not simply write “my landlord owes money.” Select the actual T1 reason and include a dated, itemized calculation.
