Can I legally withhold rent in Ontario if my landlord won't make repairs?

No. Ontario has no general 'repair and deduct' or rent-withholding right. If you stop paying, your landlord can serve an N4 and start eviction for non-payment — even if the repair complaint is legitimate. The correct route is to keep paying and pursue the landlord through the LTB.

What is a T6 application?

A T6 is the Tenant Application About Maintenance you file with the Landlord and Tenant Board when your landlord fails to repair or maintain the unit. The LTB can order the repairs done, order a rent abatement (a partial refund) for the period you went without, and in some cases order other remedies.

What is a rent abatement?

A rent abatement is a reduction or partial refund of rent to compensate you for the reduced value of a unit that wasn't properly maintained. If you lived for months with, say, a broken heating system or persistent leak, the LTB can order the landlord to pay back a portion of the rent you paid during that time.

Can I pay for an urgent repair myself and deduct it from rent?

Be very careful. Ontario doesn't give tenants a clear right to unilaterally deduct repair costs from rent, and doing so can expose you to an N4. In limited urgent situations you may be able to seek reimbursement through the LTB afterward, but deducting first and arguing later is risky. Get advice before doing it.

What should I do first if my landlord ignores repairs?

Put the request in writing and keep a copy, document the problem with dated photos and notes, and give the landlord a reasonable chance to act. If they don't, contact municipal property standards for health-and-safety issues and file a T6 with the LTB. Keep paying your rent throughout.

Can I Withhold Rent if My Landlord Won't Make Repairs in Ontario?

It feels like the obvious leverage: stop paying until they fix it. In Ontario, that instinct can get you evicted. The good news is there's a route that actually works — and it can even get you money back. Here's the right way to force a repair.

The Short Answer: No — Don't Withhold

Ontario does nothave a general rent-withholding or "repair and deduct" right. Even if your complaint is completely valid, the moment you stop paying, your landlord can serve an N4and begin eviction for non-payment of rent. You'd be trading a repair dispute you could win for an eviction fight you might lose.

Your obligation to pay rent and the landlord's obligation to maintain the unit are treated as separate duties. You enforce the repair duty through the Landlord and Tenant Board — not by holding rent hostage. (If you've already received an N4, see our guide to the N4.)

The Route That Works: The T6 Application

The real tool is the T6 — Tenant Application About Maintenance. You file it with the LTB when your landlord fails to meet their repair and maintenance obligations. If you succeed, the Board can:

Order the repairs to be completed, sometimes by a deadline;
Order a rent abatement — a partial refund of the rent you paid while the unit wasn't properly maintained;
Order other remedies, such as reimbursing you for related out-of-pocket costs, or in serious cases, allowing you to arrange repairs.

That rent abatement is the key point: done properly, you can effectively recover money for a badly maintained unit — the outcome people hopeto get by withholding, but through a route that doesn't put your tenancy at risk.

Build Your Case Before You File

A T6 lives or dies on evidence. Before and during the dispute:

Request repairs in writing — email or letter — and keep every copy. A paper trail showing the landlord knew and didn't act is powerful.
Document everything: dated photos and video, a log of when the problem started and how it affects you, and any related expenses.
Contact municipal property standards for health-and-safety issues (no heat, pests, mould, unsafe conditions) — their inspection report supports your case.
Keep paying your rent the entire time, so the landlord can't flip the script with an N4.

Our guide on how to get your landlord to fix something covers the escalation steps in more detail.

What About Paying for an Urgent Repair Yourself?

Tempting in an emergency, but risky. Ontario doesn't give tenants a clear right to unilaterally deduct repair costs from rent, so paying and then docking your rent can still draw an N4. In narrow, genuinely urgent situations you may be able to seek reimbursement through the LTB afterward — but get advice from a legal clinic first rather than deducting on your own. The safer play is almost always: keep paying, document, and file the T6.
