Can You Withhold Rent for Repairs in Ontario? T6 and the LTB

When a landlord leaves a leak, a broken heater or a pest problem unfixed, it is tempting to stop paying rent until the work is done. Many tenants ask whether that is legal, and the honest answer is that it is risky and depends on the facts.

This article explains what can happen if you hold back rent, how the T6 application to the Landlord and Tenant Board (LTB) works, and what to prepare. It is general information, not advice on your situation.

Is withholding rent allowed?

Ontario's Residential Tenancies Act, 2006 (RTA) applies to rental units despite any agreement or waiver to the contrary, and any lease term that conflicts with the Act is void. That protects you from a lease that tries to take away your rights, but it does not by itself mean you may keep the rent.

One clear example of a tenant being allowed to withhold rent is narrow: for most private rentals, landlords must use the Ontario standard lease for new leases, and if a tenant asks for it in writing and does not receive it within 21 days, the tenant may withhold one month's rent. Whether you can withhold because of repairs depends on your facts, and it is worth confirming with a lawyer before you stop paying.

What can happen if you stop paying

A landlord who says rent is owing can serve an N4 notice. The termination date must be no earlier than the 7th day after the notice is given, for notices given on or after September 21, 2026, and the earlier 14-day period applies to notices given before that date. The notice must state the rent owed, and it becomes void if you pay all arrears plus any further rent due before the landlord applies to the Board.

• If the landlord applies, you may raise any issue that could be the subject of a tenant application at the arrears hearing.
• For landlord applications filed on or after September 21, 2026, you must first pay the landlord half of the claimed arrears at least seven days before the hearing, and that payment cannot be made to the LTB in trust.
• If you pay the arrears, further rent due and the landlord's application fee before an eviction order issues, the application is discontinued.
• After an order becomes enforceable but before it is carried out, you may pay and bring a motion, but only once per tenancy agreement period.

On the other side, a landlord cannot remove you or change the locks. A notice does not end a tenancy by itself, the landlord must apply to the LTB, and only the Sheriff can enforce an eviction order.

How a T6 application works

Whether a T6 is the right application for your repair problem depends on your situation, so it is worth confirming with a lawyer. It can be completed and filed through the Tribunals Ontario Portal. The published fee for T1, T2, T5 and T6 applications is $53, or $48 through the Portal. Fees are non-refundable, and a Fee Waiver Request form is available.

The LTB serves only the application and the notice of hearing. Any other documents the LTB orders you to serve must be served under strict rules. Hearings are virtual (by Zoom video or telephone), written, or in person, and in-person hearings are scheduled only on approved accommodation requests. Parties should join at least 15 minutes early.

Evidence and timelines

Evidence must generally be disclosed at least 7 business days before the hearing, or 5 days for responding evidence, but tenants responding to a non-payment application must give evidence no later than 7 days before the hearing. Photos, dated messages to the landlord and inspection records are the kind of material people commonly gather.

These timelines come from a page that may be out of date, so check the LTB's current service timelines. While you wait, Portal users can try the Online Dispute Resolution tool, and mediation with a neutral person is also available.

What to do next

• Write to your landlord describing each repair problem and keep a copy.
• Photograph the problems and keep dated records of every request.
• Keep paying rent, or speak to a lawyer first about whether holding it back is justified in your case.
• Check the current T6 form and fee on the Tribunals Ontario site before filing.
• If you receive an N4 or an LTB notice of hearing, note every date and deadline right away.
