Renting a home in Ontario should mean having a clean, safe, and healthy place to live. Mold, pests, leaks, unsafe wiring, and other health hazards can affect your well-being. This guide explains Ontario tenant rights, landlord responsibilities, and the steps to take when you find a hazard in your rental unit.
Your Right to a Safe and Healthy Rental Home
Under Ontario law, tenants have the right to live in a home that is safe, fit for habitation, and in good repair. Health and safety concerns may include:
- Mold and dampness
- Pest infestations, including bed bugs, cockroaches, and mice
- Unsafe or unsanitary conditions, such as leaks, broken smoke alarms, or structural hazards
Landlords are legally required to maintain rental units and common areas in a good state of repair and in compliance with health, safety, housing, and maintenance standards. These obligations are set by the Residential Tenancies Act, 20061.
Common Health Hazards in Rentals
- Mold: Often caused by leaks, poor ventilation, or unaddressed water damage.
- Pests: Infestations involving bed bugs, rodents, cockroaches, and other vermin.
- Lead or asbestos: These may be present in older homes and should be addressed by qualified professionals.
- Fire and safety risks: Missing smoke or carbon monoxide detectors, faulty wiring, and other safety concerns.

What Are Landlords Responsible For?
Ontario landlords must address hazards even when the tenant was not the source of the problem. Their responsibilities may include:
- Addressing mold and arranging repairs when needed
- Arranging pest removal, including fumigation or extermination when required
- Completing routine repairs and keeping heating, plumbing, and electrical systems safe and functional

Action Steps if You Discover Mold or Pests
- Document the problem: Take photos or videos and note the locations and dates.
- Notify your landlord in writing: Describe the issue, request a repair or treatment, and keep a copy of your message.
- Allow reasonable time for a response: Depending on the severity, 24–72 hours is common for health hazards.
- Seek help if the problem is not resolved: Contact your municipal property standards office or apply to the Landlord and Tenant Board (LTB).
Filing a Complaint or Applying to the Landlord and Tenant Board (LTB)
If your landlord does not act after receiving written notice, you can submit an "Application about Maintenance – Form T6" to the Landlord and Tenant Board of Ontario. The application can result in an order for repairs, rent abatement, or compensation.
- Form name and number: Application about Maintenance – Form T6
- When to use it: When your landlord does not fix a health hazard after written notice. For example, you reported mold but repairs have not been completed for a week.
- How to file: Complete Form T6 and submit it online or in person to the LTB. Attach photos, videos, and communication records.
Special Note: Pest Infestations
Tenants should take pest problems seriously and should:
- Report pest problems immediately.
- Cooperate with treatments by following preparation instructions and allowing access for pest control.
- Document pest sightings and all communication with the landlord.

What If Your Unit Is Uninhabitable?
Serious hazards may make a rental unit unsafe to live in. Depending on the situation, you may:
- Be entitled to a rent reduction or compensation.
- Have grounds to terminate your tenancy early. Speak to the LTB for advice.
Where possible, obtain written orders from local bylaw or health inspectors as additional proof.
