Can a tenant withhold rent for repairs in Ontario?

Last updated October 25, 2026 · Written for small Ontario landlords

Short answer: No. The LTB's guide to the Residential Tenancies Act says a tenant should not withhold any part of the rent, even if they feel maintenance is poor or a necessary repair has not been done, and that a tenant could be evicted for withholding rent without getting approval from the LTB. Rent that isn't paid is still rent owing, so you can give an N4 (RTA s. 59). The tenant's route is to apply on Form T6, or to raise the repair problem at your rent hearing, and only the LTB can order a rent abatement (RTA s. 30(1)).

The other side of this is just as firm. You must keep the unit in a good state of repair and fit for habitation, even if the tenant knew about the problem before signing (s. 20). A tenant who can't withhold rent can still win money back from you at the LTB, and a serious repair breach can stop your eviction. This page covers units under the RTA; if your renter shares your kitchen or bathroom and you live there, see renting rooms in your home.

What each side can do

Situation	What the law says	Source
Tenant holds back some or all of the rent because of a repair	The rent is still owing. You can give an N4 the day after the rent was due, with a termination date at least 7 days later.	LTB guide; RTA s. 59(1); N4 instructions
Tenant wants the rent reduced for a repair problem	They apply on Form T6. If the LTB finds you breached s. 20, it can order an abatement, order repairs by a set date, or order you to pay the tenant's reasonable repair or out-of-pocket costs.	RTA ss. 29(1), 30(1); T6 instructions
Deadline for the tenant's T6	No more than one year after the conduct. The T6 instructions say that if the problem has been fixed, the tenant must apply within one year of the date it was fixed.	RTA s. 29(2); T6 instructions
The tenant never told you about the problem	In deciding the remedy, the LTB must consider whether the tenant told the landlord about the problem before applying.	RTA s. 30(2)
Tenant raises repairs at your L1 hearing	For applications filed on or after Sept 21, 2026, they must give advance written notice and pay you at least half the arrears claimed, at least 7 days before the hearing.	RTA s. 82(2); Tribunals Ontario Sept 21, 2026 update
You are in serious breach of your repair duties	The LTB must refuse to evict.	RTA s. 83(3)(a)
You cut off heat, power or water to push the tenant	Not allowed. The LTB guide lists heat (Sept 1 to June 15), electricity, fuel and hot or cold water as vital services you can't shut off or interfere with.	RTA s. 21; LTB guide

Worked example

Example numbers only. Rent is due on Sunday, November 1, 2026. The tenant says the bathroom fan has been broken for a month and pays nothing that day.

Earliest N4: Monday, November 2, 2026, the day after the rent was due.
Termination date: given by hand on November 2, the date must be Monday, November 9, 2026 or later. Add 5 days first if you mail it. The free N4 date calculator does the counting.
If the tenant pays everything owing before you file the L1, including any rent that has come due since, the N4 is void (RTA s. 59(3)).
If not, you can file an L1 from Tuesday, November 10, 2026. If the tenant wants to raise the fan at that hearing, they must give you and the LTB a written description of the issue and their evidence, and pay you at least half the arrears claimed, at least 7 days before the hearing (see the half-arrears rule).
Either way, fix the fan. If the tenant proves the repair problem, the order can include a rent abatement or an order to do repairs, and a serious breach means no eviction.

Where the toolkit helps: The toolkit's LTB-Ready Evidence Pack keeps a communication log for every repair request and reply, and a rent ledger with a running balance and a receipt log, so the repair history and the rent owing are both written down with dates. See what is inside the $19 toolkit

What to do when a tenant says they won't pay until you fix it

Answer the repair request in writing and date it. Say when you or your trade will come, and give 24 hours' written notice to enter for repairs (see landlord entry notice).
Do the repair. Your duty under s. 20 doesn't depend on the tenant paying.
Treat the rent separately. Note what was due and what was paid. If rent is short, the N4 is the tool, not a lockout or a utility shut-off.
Keep the paper trail. Dated requests, replies and photos are what the LTB looks at under s. 30(2) and at a hearing.

Mistakes to avoid

Ignoring the repair because the tenant stopped paying. A serious breach of your responsibilities means the LTB must refuse the eviction (s. 83(3)(a)).
Agreeing to a rent cut by text and then filing for the full amount. If you agree to anything, put it in writing with the amount and the months.
Shutting off heat, power or water, or changing the locks without giving the tenant new keys (ss. 21, 24).
Filing for eviction because the tenant complained to the city about repairs. The LTB must refuse an application brought for that reason (s. 83(3)(b)).
Using an old N4. Download the current form from the LTB forms page; see the N4 7-day rule.
