Heat and Hot Water Issues for Tenants in Ontario

Utilities & Services Ontario 3 min read · published March 09, 2026 Flag of Ontario

In Ontario, tenants often face challenges related to heating and hot water in their rental properties. As these utilities are essential for a comfortable living, understanding tenant rights and responsibilities under the Residential Tenancies Act, 2006 is crucial. Knowing what to do when issues arise can help tenants maintain a safe and comfortable home.

Keep copies of all notices and communications about heating or hot water issues. You may need these documents if you file with the LTB or request repairs.

Landlord Responsibilities

Landlords in Ontario are required to provide and maintain suitable heating in rental units. As per the Residential Tenancies Act, 2006, heating systems must be operational from September 1st to June 15th, maintaining a minimum temperature of 20 degrees Celsius. Additionally, access to hot water must be consistent and sufficient throughout the year.

The minimum temperature requirement runs Sept 1 to June 15 each year, and hot water must be available year-round. If you notice persistent failures, document dates and temperatures and bring this to your landlord's attention in writing.

Heating and Hot Water Issues

Tenants facing problems with heating or hot water should first contact their landlord in writing. If the issue is not resolved promptly, tenants may file a complaint with the Landlord and Tenant Board (LTB). For emergencies, contacting city or municipal services might be necessary.

If there’s no timely response, set a clear deadline (for example 5–7 days) and follow up in writing. Collect emails, letters, and any photos or receipts to support a future LTB filing.

In some cases, maintenance obligations may be necessary to address heating and hot water issues. For more details on this, tenants can refer to Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.

Routine repairs are a shared duty; keep a written log of issues, dates, and responses, and refer to the Routine Repairs page for examples of timelines and required steps.
