Ontario Rental Maintenance & Repairs Guide for New Tenants

Maintenance & Repairs Ontario 6 min read · published March 09, 2026 Flag of Ontario

Just moved into your Ontario rental? Maintenance and repairs are among the most important issues new tenants face. Knowing what repairs landlords must handle, what falls to you, and what to do when something breaks will help ensure your home stays safe and comfortable. This guide will walk you through key rules, common scenarios, and actions you can take if repair issues arise in your Ontario rental.

Understanding Repair and Maintenance Responsibilities in Ontario

Both tenants and landlords have clear responsibilities under Ontario’s Residential Tenancies Act, 2006[1]. In general:

  • Landlords are responsible for maintaining the rental unit and property in good repair. This includes plumbing, heating, appliances provided in the lease, and ensuring the place meets health, safety, housing, and maintenance standards.
  • Tenants must keep their home reasonably clean and repair any damage they cause beyond normal wear and tear.
Tip: Review your rental agreement for any additional repair or maintenance responsibilities. It's always best to keep records of all communications and repair requests.
Action tip: Start a repair diary. Save messages, emails, and receipts; take dated photos of issues; note when problems started and any responses from your landlord. This helps document who’s responsible and timelines if a dispute arises.

Examples of What Landlords Must Repair

  • Broken heating systems during winter
  • Leaking roofs or windows
  • Faulty plumbing, electrical, or appliances supplied with your lease
  • Maintaining common areas, such as hallways or laundry rooms
  • Addressing pest infestations affecting your health or comfort

Notifying Your Landlord: Making a Maintenance Request

If something needs repair, tell your landlord as soon as possible. It’s best to do this in writing—an email or letter is ideal. Include:

  • What’s broken or needs fixing
  • How it affects you or your safety
  • The date you are reporting it
  • Your contact information

Keep a copy of the notice for your records. Most issues must be fixed in a reasonable time, but emergencies (like no heat in winter or burst pipes) should be addressed much faster.

After you send a repair request, attach photos and a clear timeline of events, and keep a copy of the message. Send via email or written notice to create a date trail, and note any responses. If the issue isn’t fixed in a reasonable time, follow up and consider escalating to the Landlord and Tenant Board for guidance.

Emergency vs. Routine Repairs

Some repairs require urgent attention. Ontario’s rules distinguish between emergencies (issues threatening safety or causing major damage) and routine maintenance. Examples:

  • Emergency repairs: No heat in winter; major water leaks; electrical hazards
  • Routine repairs: Broken appliance, clogged drain (not caused by tenant), peeling paint

For more details, see Emergency Situations and Repairs: Tenant Rights and Responsibilities and Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.

If your landlord does not fix the problem, you may have the right to take the next step with the official tribunal.

The Landlord and Tenant Board (LTB)

Ontario tenants have strong protections. If your landlord refuses to make required repairs, you can apply to the Landlord and Tenant Board (LTB) for help. The LTB can order the landlord to make repairs or compensate you in some cases.

If you file with the LTB, gather evidence such as dated photos, repair requests, correspondence, and your lease. The process can take weeks to months, and hearings may require witnesses or documentation.

Key Official Forms for Maintenance & Repairs

  • Form T6: Tenant Application about Maintenance
    Use this if your landlord isn't repairing or maintaining your unit as required by law.
    • When to use: If notified in writing and repairs are not addressed within a reasonable time.
    • Where to get it: LTB Official Tenant Forms
  • Form N5: Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding
    Landlords may serve this if a tenant is causing damage (not normal wear/tear).
    • Why it matters: Tenants should be aware this notice could be used if you damage the property.
    • Where to get it: Download Form N5 (PDF)

Complete these forms clearly and honestly. The LTB website above has instructions for each form, and you can also visit in person for assistance.

In an emergency, contact emergency services if there’s an immediate danger, then notify the landlord as soon as possible. Don’t delay reporting hazardous conditions.

What If Repairs Affect Your Health or Safety?

Repairs that endanger your health or safety—such as mould, broken locks, or pest infestations—must be addressed promptly. For more on these concerns, see Health and Safety Issues Every Tenant Should Know When Renting. You may also contact your local municipal bylaw or public health unit if conditions are unsafe.

Preparing for a Maintenance Inspection

Your landlord may need to enter for repairs or inspections. They must give you at least 24 hours’ written notice (except for emergencies) and state the reason, date, and time (between 8 a.m. and 8 p.m.).

Before a visit:

  • Secure valuables and pets
  • Clean the area to be repaired
  • Make a list of any other issues you spot

What Happens if Repairs Aren't Made?

If your landlord ignores repeated requests:

  • Keep copies of all requests and replies
  • Take dated photos or videos of the needed repairs
  • Contact your local property standards office or bylaw enforcement if health and safety are affected
  • File Form T6 with the LTB
Keep a running log of requests, responses, and dates of follow-up. This helps when preparing a T6 application or a bylaw complaint and shows persistent issues.

Where Can I Learn More?

In Ontario, you have pathways to enforce repairs, including the LTB and municipal bylaw offices. Start with written requests, keep records, and escalate only if necessary.
