Managing Heat and Hot Water Issues in Ontario Rentals

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

As a tenant in Ontario, having reliable heat and hot water in your rental unit is crucial, especially during the colder months. Understanding your rights and responsibilities, as well as knowing how to address these issues, is essential for maintaining a comfortable home. Under the Residential Tenancies Act, 2006, landlords must provide an environment that meets the minimum health and safety standards, which include sufficient heating and access to hot water.

The Residential Tenancies Act treats heating and hot water as essential services. Keep a log of dates and times when heat or hot water are missing and save all repair requests in writing for later use, such as in a potential LTB filing or tenancy review.

Understanding Heat and Hot Water Regulations

In Ontario, landlords must ensure that heat is provided starting September 1st until June 15th of the following year to maintain an indoor temperature of at least 20°C. If this requirement is not met, tenants can take steps to resolve the situation promptly.

Fact: The heating season runs Sept 1–Jun 15 with a minimum 20°C indoor temperature. If heat is lacking, document dates and thermostat readings and send a written repair request to your landlord right away.

Steps to Take If You're Facing Issues

  • Document the Issue: Keep a detailed record of the dates and times when you experienced a lack of heat or hot water.
  • Communicate with Your Landlord: Notify your landlord as soon as you notice the issue. Written communication is often best, providing clear documentation of your concerns.
  • Understand Your Rights: Heating and hot water are considered essential services. Consult the Common Issues Tenants Face and How to Resolve Them if these issues persist.
  • File a Complaint: If unresolved, you may file an application with the Ontario Landlord and Tenant Board (LTB) for an order to resolve the issue through Form T2 - Application About Tenant Rights. Form T2 can be accessed and filed online.
Tip: When communicating with your landlord, keep copies of all messages and consider sending repair requests by email so you have timestamps and records.

Additional Considerations

It is crucial to maintain open communication with your landlord when dealing with heating issues. Make sure you meet your own responsibilities, such as ensuring all windows and doors are properly shut to conserve heat.

Should the problem persist, contacting local tenant advocacy groups might offer additional solutions or advice.

Insight: Tenant advocacy groups can help interpret forms and deadlines; bring your log, copy of your tenancy agreement, and a summary of steps you've already taken.

Need Help? Resources for Tenants

Fact: The Ontario Landlord and Tenant Board and Social Justice Tribunals Ontario are official avenues for filing disputes; keep confirmation numbers and saved submissions for your records.
