What Are Maintenance and Repair Rights for Ontario Tenants?

Under the Residential Tenancies Act, 2006, landlords must maintain rental homes in good repair and follow all health, safety, and housing standards (even if your lease says otherwise). Tenants are responsible for keeping homes reasonably clean and not causing damage on purpose or through negligence.[1]

Always keep a record (emails, texts, dated letters) when you report maintenance issues.

How to Request Repairs in Ontario

Start by notifying your landlord in writing with the time, date, and details of the problem. If urgent (like no heat in winter), call as well—but always follow up in writing. Here’s what to do if things don't get fixed:

  • Send a second written repair request if the first is ignored.
  • Document delays and your attempts to communicate.
  • If unsafe or illegal, contact your local bylaw office or municipal property standards.

Taking the Next Step: Making a Maintenance Application

If major issues aren't resolved, tenants can apply to Ontario's Landlord and Tenant Board (LTB).

  • Form T6: Tenant Application about Maintenance
