Tenants in Ontario: Enforcing Repairs Laws

Maintenance & Repairs Ontario 3 min read · published March 09, 2026 Flag of Ontario

As a tenant in Ontario, maintaining a safe and livable rental environment is crucial. Under Ontario's Residential Tenancies Act, 2006, tenants have the right to expect their landlords to conduct necessary repairs and maintenance. However, understanding how to enforce these laws can be challenging. This article will guide you through enforcing repairs laws as a tenant in Ontario.

Before you start repairs, gather photos, dates, and copies of any written requests. Create a simple log noting each issue, date reported, and any safety risks to health. This helps you build a clear timeline if you need to involve the LTB.

Understanding Tenant and Landlord Repair Responsibilities

Landlords are required by law to keep rental properties in a state of good repair, ensuring that the property meets health and safety standards. This includes maintaining structures, plumbing, heating systems, and electrical wiring. Tenants, on the other hand, must maintain cleanliness and report any issues promptly.

Common Repair Issues Tenants Face

  • Heating and cooling system failures
  • Leaking plumbing
  • Mold or pest infestations
  • Electrical malfunctions

Steps to Enforce Repair Laws

Communicate with Your Landlord

Start by notifying your landlord in writing about the needed repair. Include details of the issue and any potential risks to safety or health. Retaining a copy of all correspondence is advised for your records.

Include specifics like exact location, model numbers, and when you first noticed the issue. Ask for written acknowledgement and set a reasonable response deadline; keep copies of all messages.

If Repairs Are Not Made: Next Steps

If your landlord does not respond, you may need to escalate the issue. You can apply to the Ontario Landlord and Tenant Board (LTB) using the official form T6: Tenant Application About Maintenance.

Example: If your heating system fails during winter, and your landlord does not repair it within a reasonable time, you can file a T6 form available here. This application addresses the repair issue and may result in your rent being reduced until repairs are completed.

You can file the T6 online or by mail with the Ontario LTB. Attach copies of your written repair requests, the landlord's responses (or lack thereof), and any photos or receipts as evidence.

Understanding Lease Obligations

Both tenants and landlords have specified obligations. For more information, see Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

Take a moment to review the obligations guide and your lease to confirm both sides’ duties. If a dispute arises, citing those obligations can help frame a clear request for timely repairs.

Tenant Rights and Health Concerns

Repairs are often vital due to their impact on health. Issues such as mold or pest infestations can significantly affect your well-being. Learn more about health and safety issues here.
