Housing Standards in Ontario: What Landlords Must Provide in 2026

Ontario law requires landlords to keep rental properties in a good state of repair and fit for habitation — understanding these obligations prevents LTB maintenance orders and rent abatements.

Ontario Housing Standards Checklist (2026)

Typical requirements as of 2026 — exact standards come from your municipal property-standards bylaw and provincial regulations. Verify with your municipality and the LTB.

The Landlord's Duty to Repair

Ontario's Residential Tenancies Act states that every landlord shall maintain a residential complex, including the rental units in it, in a good state of repair and fit for habitation and for complying with health, safety, housing and maintenance standards. Importantly, this duty applies even if the tenant knew about a state of disrepair before moving in — renting a unit "as-is" does not waive the landlord's obligations.

In Waterloo Region, day-to-day enforcement is local: Kitchener and Cambridge enforce property-standards bylaws through municipal bylaw officers, and the City of Waterloo also runs a rental housing licensing program for many low-rise rentals — an inspection-backed regime that most other Ontario municipalities don't have. If you own rentals in Waterloo, confirm your licensing obligations with the city.

Heat, Plumbing and Hot Water Standards

Heat is the most frequently enforced standard. In most Ontario municipalities landlords must maintain a rental unit at a temperature of at least 20°C during the heating season — commonly September 1 to June 15, though local bylaws vary on dates and temperature. A tenant can apply to the LTB for an order to repair heating, an abatement of rent while the issue persists, and potentially a requirement for the landlord to provide alternative housing. As of 2026, check your municipality's exact heating bylaw.

Plumbing standards require that all supplied water systems be maintained in good working order, that drains be functional, and that hot water be available at an appropriate temperature. A rental unit without functioning hot water is not fit for habitation and exposes the landlord to an immediate LTB application.

Pests, Appliances and Ongoing Maintenance

Pest infestation is a maintenance obligation. While tenants are responsible for maintaining cleanliness, infestations that originate from building-wide conditions or from natural pest pressure from adjacent units or the exterior are the landlord's responsibility to address. A professional pest control treatment is generally required.

Appliance maintenance obligations depend on what's included in the lease. Appliances supplied as part of the tenancy — refrigerator, stove, washer, dryer — must be maintained in good working order. Landlords who supply appliances and fail to repair or replace them when they fail are in breach of their maintenance obligation.

Frequently Asked Questions

What temperature must a landlord provide in Ontario?

At least 20°C during the heating season in most municipalities — commonly September 1 to June 15, though dates and temperatures vary by local bylaw. As of 2026, verify your city's heating bylaw and current LTB guidance.

Who enforces housing standards — the city or the LTB?

Both. Municipal bylaw officers enforce local property-standards bylaws (with orders to comply), while tenants can also apply to the LTB for repair orders and rent abatements. In Waterloo Region, Kitchener, Waterloo and Cambridge each have their own bylaw enforcement.

What can a tenant do if a landlord doesn't make repairs?

File a maintenance application with the LTB, which can order repairs, rent abatements and cost reimbursements — or call municipal bylaw enforcement, which can issue orders against the property. Landlords who respond promptly and document repairs rarely face either.

Are landlords responsible for mice, cockroaches and other pests?

Generally yes, when the infestation stems from building conditions, adjacent units or the exterior. Tenants are responsible for reasonable cleanliness. Professional treatment is usually required, and repeat treatments should be documented.

Do landlords have to fix appliances they supplied?

Yes. Any appliance included in the tenancy must be kept in good working order — repaired or replaced at the landlord's cost when it fails through normal use.

Can renting a unit "as-is" waive the landlord's repair obligations?

No. The landlord's duty to repair applies even if the tenant knew about the disrepair before moving in. "As-is" clauses do not override the Residential Tenancies Act.

Do I need a rental licence in Waterloo Region?

The City of Waterloo runs a rental housing licensing program covering many low-rise rental properties, with inspections and per-unit requirements. Kitchener and Cambridge rely on property-standards bylaws instead. As of 2026, confirm licensing requirements with the specific city before leasing.
