Common Repairs Disputes in Ontario Rentals

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

In Ontario, rental maintenance and repairs can become a contentious point between tenants and landlords. Understanding your rights as a tenant under the Residential Tenancies Act, 2006 can help you address common repair disputes effectively.

Responsibilities of Landlords and Tenants

Both landlords and tenants in Ontario have specific obligations when it comes to maintenance. Landlords must ensure that the rental property is habitable, safe, and in good repair. This includes complying with health, safety, and housing standards.

  • Tenants must maintain cleanliness and report necessary repairs.
  • Damage caused by tenants beyond normal wear and tear may be the tenant's responsibility.

Understanding these mutual responsibilities is essential for maintaining a harmonious rental relationship.

Keep a dated record of who is responsible for each repair and the expected timelines. If issues persist, consult the Ontario LTB for guidance.

Common Repair Issues

Disputes often arise over the speed and adequacy of repairs. Common issues include:

Document each issue with dates and photos as soon as you notice a problem; this builds a clear timeline if the case escalates.
  • Leaking fixtures or plumbing problems
  • Heating system failures, especially during winter
  • Mold due to inadequate ventilation
  • Broken appliances that were included in the rental agreement

To address these issues, tenants should promptly inform landlords in writing, allowing for time to arrange repairs.

In your written notice, list every problem, give specific locations, attach photos, and include a suggested deadline for repair. Keep copies of the message and any replies.

Steps for Resolution

  1. Document the issue: Take photos or videos and note dates of all communications.
  2. File a complaint: If issues persist, a tenant may file for repair work to be mandated by the Ontario Landlord and Tenant Board.

If negotiation fails, tenants might need to file a formal complaint with the LTB. This requires completion of specific forms available from the official Ontario LTB website.

Have ready evidence (photos, maintenance records, and dates of contact) when filing with the LTB, and submit the forms with copies to the landlord.
Always ensure that all communications and requests for repairs are documented and sent through traceable means, such as email or registered mail.
