Emergency Repairs Ontario Landlords Must Address Now

Safety & Security Ontario 4 min read · published March 09, 2026 Flag of Ontario

When sudden problems threaten your health or safety in your Ontario rental home, the law requires landlords to act quickly. Understanding what counts as an emergency repair—and how to exercise your rights—helps keep you safe and prevents issues from getting worse. This article walks Ontario tenants through emergency repair obligations, repair request steps, essential forms, and where to get help.

What Are Emergency Repairs in Ontario Rentals?

Emergency repairs are urgent issues that make your home unsafe or unfit to live in. Under the Residential Tenancies Act, 2006, Ontario landlords must quickly fix problems that risk your well-being or could cause significant property damage1. Examples of emergencies include:

  • No heat in winter months
  • Major plumbing leaks or flooding
  • Broken windows or doors that affect security
  • Loss of essential services like electricity or water
  • Cross-contamination from sewage
  • Fire or flood damage

These situations require rapid action because they put your health or safety in jeopardy. For non-urgent issues, see Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.

Landlord Obligations: Acting Without Delay

Ontario law obligates landlords to repair emergency issues immediately or as soon as possible. Delaying could lead to further property damage or even legal action. Both landlords and tenants have roles to play:

  • Landlords must respond promptly to emergency repair requests.
  • Tenants should notify the landlord right away, preferably in writing.

If you're unsure about your responsibilities, review Obligations of Landlords and Tenants: Rights and Responsibilities Explained for details.

What Counts as "Immediate"?

The law does not give an exact number of hours, but "immediate" generally means addressing the issue as soon as the landlord is made aware, without unnecessary delay.

In an emergency, keep a simple log of dates, times, and what was reported to your landlord. This makes it easier to show you've asked for a repair promptly and to escalate if needed.

How to Request an Emergency Repair

When an emergency repair is needed:

  • Contact your landlord right away, even by phone, text, or email.
  • Follow up with written notice to create a record.
Keep copies of all your communications with your landlord. Written notice helps protect your rights if you need to escalate later.

In rare cases where the landlord cannot be reached, you may arrange the repair yourself—but only for real emergencies. You can then ask for reimbursement, provided the repair was essential for health or safety.

Key Official Form: Tenant Application about Maintenance (Form T6)

  • Form Name: Tenant Application about Maintenance (T6)
  • When to use: If your landlord refuses or fails to emergency repairs, you can file this application with the Landlord and Tenant Board (LTB).
  • How it's used: Submit the T6 form to explain the problem, what you've asked your landlord to do, and any expenses you've had to cover.
  • Download Form T6 (PDF)

For a full description of the process, see the LTB’s guide on tenant forms and applications.

What If Your Home Is Unsafe?

If an emergency makes the unit uninhabitable (for example, after a fire or flood), you may have grounds for a rent reduction or compensation. Sometimes, you may even be allowed to move out on short notice. For more on your rights in these scenarios, visit the Tenant Rights in Ontario facts page.

If the unit is uninhabitable, document the condition and seek guidance from the LTB or local housing authority on relocation or rent relief; keep temporary housing receipts and communicate with your landlord in writing.

Your Rights to a Safe and Healthy Rental

Emergency repairs are part of your right to live in a safe, healthy space. If your safety is at risk from hazardous conditions, you can also report the issue to your municipality's property standards or bylaw office.
