For Ontario tenants, ongoing mold or maintenance issues can affect both health and quality of life. Understanding how tribunals and courts have handled similar cases can empower renters to address problems more confidently, assert their rights, and seek appropriate remedies. This article summarizes leading cases, official processes, and legislation to help Ontario tenants tackle mold and maintenance concerns effectively.

Ontario Tribunal: Who Handles Mold and Maintenance Disputes?

The Landlord and Tenant Board (LTB) is the official tribunal that resolves most residential tenancy disputes in Ontario—including cases involving mold or poor maintenance. The LTB applies the Residential Tenancies Act, 2006, which outlines the legal duties of both landlords and tenants.

Mold and Maintenance: Tenant and Landlord Duties

• Landlord's Duty: Keep the rental unit in a good state of repair and comply with health, safety, housing, and maintenance standards at all times^[1].
• Tenant's Duty: Maintain cleanliness and avoid causing damage or unsafe conditions.

Mold is treated by the LTB as a health and safety matter. Severe mold or persistent water leaks often signal maintenance failures. Tenants should report such problems in writing to their landlord as soon as possible.

Notable Ontario Mold & Maintenance Litigation Summaries

• Akelius Real Estate Management Ltd. v. Atkinson (LTB Order, 2017): The LTB found that ongoing leakage, visible mold, and delayed repairs posed significant health risks, ordering the landlord to complete repairs and abate rent. Tenants were awarded a rent reduction and compensation for affected personal property.
• D.S. v. P.R. (LTB Order, 2022): Mold in a basement unit persisted for months. The landlord failed to act promptly despite written complaints. The LTB found a breach of health and safety obligations, ordering a rent rebate and requiring immediate remediation.

These cases show that tenants who provide detailed written records, evidence (photos, emails), and use LTB processes have a stronger chance of success.

Filing a Mold or Maintenance Complaint: Step-by-Step Guide

• Take photos and keep a written log of all maintenance issues and communications.
• Notify your landlord in writing and allow reasonable time for repairs.
• If problems persist, consider submitting an LTB application.

Relevant Official Form: Application About Tenant Rights (Form T2)

• Form Name: Application About Tenant Rights (Form T2)
• When Used: If your landlord has failed to repair, maintain, or fix health and safety issues (including ongoing mold) after you've given them notice.
• How it's Used: Attach photos, inspection reports, and copies of written complaints. State the remedies you seek (e.g., rent reduction, repairs, compensation).

If the mold presents immediate harm to health, contact your local public health unit, who may conduct an inspection and issue orders directly to the landlord.

What Happens After Filing with the LTB?

The board schedules a hearing where both sides can present their evidence. Potential outcomes include:

• Orders for repairs within a set timeline
• Rent reduction or abatement
• Compensation for lost property or inconvenience

Frequently Asked Questions

1. What should I do if my landlord ignores written complaints about mold?
   Document each complaint and response. Use Form T2 to apply to the LTB for remedies if nothing is done.
2. Can my landlord evict me for reporting maintenance issues?
   No, it's illegal for a landlord to evict or threaten eviction as retaliation for legitimate repair requests or LTB applications.
3. How long does the LTB take to resolve a mold case?
   Hearing dates typically occur in several weeks, but urgent health issues may be prioritized by contacting local public health.
4. Should I stop paying rent if there's severe mold?
   Keep paying rent unless authorized by the LTB. Withholding rent can lead to eviction. Instead, seek a rent abatement through the LTB.
5. Who pays for mold damage to my belongings?
   If the landlord is responsible for the mold due to neglect, the LTB may order the landlord to reimburse you for damaged property.
