Habitability Standards — Ontario
Sourced from Canadian federal statutes and official sources. Provincial information reflects each province's own legislation and court rulings. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
Every Canadian landlord owes a statutory duty to deliver a safe, livable unit that meets building code standards. That covers working plumbing, electrical, heating, and pest control — the basics that keep a place habitable.
You can't sign this duty away. A lease clause that says "as-is" or "tenant responsible for repairs" doesn't survive contact with the statute — provincial residential tenancy law overrides whatever the contract says.
Vital services — heat, water, electricity — get extra-strict treatment. A landlord cannot shut them off for any reason, including non-payment of rent. Ontario goes further still: rentals must hold at least 20°C from September through June, regardless of whether you've asked.
When does it apply?
- All residential rental units, from the day you take possession until the day you leave.
- The duty exists whether or not you report the problem — but reporting starts the clock and creates the record.
- Covers apartments, houses, rented rooms, and most other residential units.
What to Do If Your Canadian Rental Unit Is Uninhabitable
Repair complaints succeed when there's a paper trail. Build it from the first email.
- Notify the landlord in writing — email or letter — and describe the issue clearly. Photos help.
- Give a reasonable timeframe: 24 hours for emergencies (no heat, burst pipe, gas leak), 1–2 weeks for non-urgent fixes.
- If nothing happens, call municipal bylaw enforcement for a property inspection — their report becomes evidence.
- File with your tribunal: Ontario — Form T6 at the LTB; BC — RTB complaint; Quebec — TAL application.
What should you NOT do?
- Don't withhold rent. In most provinces it's not a recognised remedy and you'll find yourself defending an eviction instead.
- Don't do major repairs yourself without going through the province's repair-and-deduct process — you likely won't be reimbursed.
- Don't shrug off mould or pests. Both get worse and both turn into health-and-safety cases.
- Don't just walk out mid-lease, no matter how bad it gets. Use the legal process — abandoning the unit weakens your claim.
How Ontario differs from federal law
Ontario landlords must maintain rental units in a good state of repair and comply with health, safety, and maintenance standards under the Residential Tenancies Act, 2006 and municipal property standards bylaws.
- Section 20 of the RTA requires landlords to maintain the rental unit and the building in a good state of repair, fit for habitation, and compliant with health, safety, housing, and maintenance standards.
- Ontario's Maintenance Standards regulation (O. Reg. 517/06) sets minimum standards including: heating must maintain at least 20°C from September 15 to June 1, adequate plumbing, working smoke and carbon monoxide detectors, pest-free premises, and structural soundness.
- Municipalities across Ontario set their own property standards bylaws that may go beyond the provincial minimums. Municipal bylaw enforcement officers can order repairs.
- If your landlord fails to maintain the unit, you can file a T6 application (Tenant Application about Maintenance) with the LTB. The LTB can order repairs and rent abatement (a reduction in rent to compensate for the substandard conditions).
- You cannot withhold rent on your own to force repairs — Ontario law requires you to keep paying rent and use the LTB process instead.
Additional Steps in Ontario
Notify your landlord of the problem in writing (email or letter) and keep a copy. If they do not fix it within a reasonable time, file a T6 application with the LTB. You can also call your municipality's property standards/bylaw enforcement department to report violations. Take photos and keep records of all communications. Community Legal Clinics can help you file LTB applications at no charge.
Relevant Law: Residential Tenancies Act, 2006, S.O. 2006, c. 17, s. 20 (Landlord's Responsibility to Repair); O. Reg. 517/06 (Maintenance Standards)
