Ontario LTB Form T6: Get Repairs or Maintenance Relief
A practical guide to reporting repair problems, selecting remedies and preparing an LTB maintenance application.
Use T6 when your landlord has not maintained or repaired your unit or the building, or has failed to meet relevant health, safety or housing standards. Current and former tenants may apply. If the problem was fixed, file within one year of the date it was fixed.
This guide explains the application; it does not file it for you or guarantee an outcome.
Before you file: build a repair timeline
Describe what broke, when it began, when you told the landlord, what happened afterward and whether it has been repaired. Keep dated photos, repair requests, replies, inspection reports and receipts. An unfinished problem is different from a problem fixed more than a year ago; do not assume all claims have the same start date.
How to fill out T6
- Part 1 — people and property: identify the unit, tenant(s), landlord, move-in date, whether you still live there and related LTB file numbers.
- Part 2 — maintenance problem: state the defect, the start and repair dates (or that it continues), when the landlord was first notified and why you believe the legal maintenance standard was not met.
- Part 3 — remedies: choose the outcome(s) you seek: repairs by the landlord, a rent abatement, payment for damaged property or expenses, permission to arrange repairs, a rent-increase restriction for serious defects, or another remedy allowed on the form. Put a dollar figure and an explanation beside every money remedy.
- Part 4 — signature: sign and date; add schedules for extra tenants or landlords if necessary.
- File: use the Tribunals Ontario Portal ($48) or an accepted other method ($53), with the completed form and fee or eligible fee waiver.
Worked example: ongoing water leak
Rent is $2,100/month. A leak leaves a bedroom unusable for 10 days, and the landlord was told on August 1. The tenant requests a $350 rent abatement, attaching dated photos and explaining why that amount is reasonable for the loss of use. The LTB—not this calculation—decides whether any abatement is justified and how much.
What happens after filing?
The LTB schedules or processes the application, gives directions about evidence and service, and considers the landlord's response. A tenant may seek an order for repairs and/or an eligible financial remedy. Do not simply stop paying rent because repairs are outstanding; use the available legal process instead.
Common mistake
A maintenance complaint without dates, proof of notice or a clear explanation of the requested remedy can be hard to assess. Keep the chronology and calculation together.
