Maintenance & Repairs Ontario 4 min read · published March 09, 2026 Flag of Ontario

Pest infestations can seriously affect tenants and their living conditions in Ontario. This guide focuses on tenant rights to pest control, how to report rodents and insects, what to document, and what options may be available when the issue is not addressed. It also explains how mold concerns relate to rental maintenance.

Understanding Your Pest Control Rights as a Tenant

Under the Residential Tenancies Act, 2006, landlords in Ontario have the obligation to maintain their rental properties in a habitable condition. This means the property must be fit for living and free of health hazards such as pest infestations and mold.

Landlord Responsibilities for Pest Infestations

Pest infestations can include rodents and insects, and they can severely affect your quality of life. Addressing pest issues is part of the landlord’s responsibility under Ontario's tenancy laws.

  • Document any signs of pests and notify your landlord in writing as soon as possible.
  • Your landlord should arrange and cover the cost for extermination services.
  • Ensure that preventive measures are taken to avoid future infestations.
When you find pests, record what you saw, where you saw it, and when you reported it. Request pest-control action in writing and keep copies of your notices and any responses from your landlord.

What to Do After Discovering Pests

Start by notifying your landlord in writing promptly. Keep dated records of pest sightings, communications, inspections, extermination services, and repairs. This documentation can help show what happened and what steps were taken.

  • Describe the pest issue and its location in your written notice.
  • Keep records of all communications and pest-control visits.
  • Ask for preventive measures to reduce the chance of future infestations.
If pests persist after you report them, request a formal pest-control plan with timelines and receipts. Recurrent infestations can strengthen your case for rent relief or required repairs.

Legal Remedies for Unresolved Pest Issues

If your landlord fails to address a pest infestation, you have several options:

  • File a Complaint: Consider filing a complaint by contacting the local health department or the Landlord and Tenant Board (LTB) in Ontario.
  • Apply to the LTB: Tenants may apply to the LTB for an order requiring the landlord to carry out repairs or to compensate for reduced enjoyment of the property.
Keep detailed records of all communication, inspections, extermination services, and repairs to support your case if legal action is necessary.

Mold and Other Rental Maintenance Issues

Mold growth can occur in areas with excessive moisture and poor ventilation. It can lead to respiratory issues and other health problems. As a tenant, you have the right to live in a mold-free environment.

  • If you notice mold, report it to your landlord in writing as soon as possible.
  • Your landlord is responsible for making necessary repairs to prevent further mold growth.
  • Keep records of all communications and repairs related to mold issues.
Under Ontario law, landlords must repair mold problems promptly and keep tenants informed. Maintain a file of dates, notices, and remediation steps to support any future LTB application.

Preventing Pest Problems and Mold

  • Ensure proper ventilation in damp areas to reduce moisture build-up.
  • Keep living spaces clean and free of food debris to deter pests.
  • Report leaks or other maintenance issues promptly to your landlord.

When to Contact the Landlord and Tenant Board

The Landlord and Tenant Board (LTB) serves as Ontario’s official tribunal for residential tenancy disputes. You should contact the LTB if:

  • Your landlord fails to address a pest infestation or mold adequately.
  • You need to apply for a rent reduction or file a formal dispute.
  1. What are my immediate steps if I discover pests in my rental?

    Notify your landlord in writing promptly and keep a record of pest sightings, communications, extermination services, and repairs.

  2. How long does the landlord have to address a pest issue?

    The landlord should address these issues promptly, with the specific timeframe depending on the severity and nature of the issue.

  3. Can I withhold rent if pest issues aren't addressed?

    Withholding rent is not recommended as it may lead to legal repercussions. Instead, apply to the LTB for resolution.

  1. How should I report a pest problem to my landlord?

    Email or send a written notice to your landlord outlining the issue, location of the pests, and request for pest-control action.

  2. How do I file a repair application with the LTB?

    Use Form T6 - Tenant Application about Maintenance to file your application with the LTB. Provide detailed evidence and documentation.
