Landlord Violation of Repair Laws in Ontario

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

In Ontario, tenants have the right to live in rental units that meet minimum standards for health and safety, as outlined in the Residential Tenancies Act, 2006. However, there are instances when landlords fail to comply with repair and maintenance obligations, which can lead to disputes and discomfort for tenants.

Understanding Repair Obligations in Ontario

Under Ontario law, landlords must maintain the rental unit in a state that complies with health, safety, housing, and maintenance standards. This includes fixing issues like broken heaters, leaking roofs, or faulty plumbing promptly.

If your landlord fails to make necessary repairs, you may have legal options to enforce your rights as a tenant.

Steps Tenants Can Take When Landlords Violate Repair Obligations

  • Document the Issue: Keep records of all communication with your landlord regarding the repair issue, including emails, text messages, and written letters.
  • Provide Written Notice: Send your landlord a written notice detailing the needed repairs and request that they address them within a reasonable time.
  • File a Complaint: If your landlord does not respond, consider filing a complaint with the Landlord and Tenant Board (LTB) using Form T6 - Tenant Application about Maintenance.
Keep a detailed repair log with dates, photos, and copies of all communications. Include receipts for any repairs you paid for yourself and note the deadline you gave your landlord in writing.

When to Use Form T6

Form T6 is used when a tenant needs to notify the Landlord and Tenant Board of a landlord's failure to maintain or repair their rental unit. Tenants can seek remedies such as rent reductions or reimbursement for repairs they paid for themselves.

You can request multiple remedies in a T6, such as a rent reduction or reimbursement for self-paid repairs. Bring contractor quotes or repair receipts to support your claim.

For more details and to download Form T6, visit the LTB Forms page.

LTB timelines vary and decisions can take weeks. Keep copies of all notices and responses and follow up if you do not hear back within a reasonable period.

Potential Outcomes of a Tenant Application

After filing a T6 application, the LTB may order the landlord to make repairs, reduce the tenant's rent, or allow the tenant to perform repairs and deduct the costs from the rent. Understanding these possibilities can help tenants effectively navigate repair disputes.

It's crucial for tenants to be aware of their rights and responsibilities to ensure that their living conditions remain safe and habitable.
