T6: T6: Tenant Application About Maintenance

A tenant application about a landlord not meeting maintenance and repair responsibilities — for example, ongoing disrepair, pests, mould concerns, or failure to meet health, safety, or housing standards.

Who this form involves

Tenants dealing with repair or maintenance problems the landlord has not fixed after being told about them.

This is an application a tenant can file with the LTB.

When it may apply

Repairs you reported have not been completed in a reasonable time.
Conditions in your unit or building may not meet health, safety, or maintenance standards.
A recurring problem (leaks, pests, heating failures) keeps returning without a lasting fix.

Cautions and limits

Time limits may apply to this form; confirm current rules with the LTB or a legal professional before you rely on any date.
Keep paying your rent unless a legal professional advises otherwise — withholding rent on your own can put your tenancy at risk.
The LTB weighs whether the landlord knew about the problem and how they responded, so your record of reporting matters a great deal.

What this process can lead to

The LTB may consider remedies such as a rent abatement (money back for the period of the problem), an order to complete repairs, or compensation for damaged property, depending on what it finds.

Outcomes are never guaranteed — the LTB decides each case on its evidence.

How to prepare

List each problem with the date you first noticed it and the date you reported it.
Gather every repair request you sent and every response you received.
Photograph or video the conditions, with dates, and keep taking updates over time.
Record any costs the problems caused you (damaged belongings, higher utility bills).
Consider having a legal clinic, lawyer, or paralegal review your application before filing.

Evidence that tends to matter

Catalogue each item in your evidence index so nothing gets lost.

Repairs — your repair tracker record of problems, requests, and responses.
Photographs and videos — dated images of the conditions over time.
Messages and emails — repair requests and landlord replies.
Inspections — any municipal property-standards inspection results.
Receipts and expenses — costs caused by the disrepair.
