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

Tenants in Quebec frequently encounter maintenance issues, particularly mold and infestations, which can affect health and safety. Understanding your rights and responsibilities as a tenant is crucial in managing such problems effectively.

Mold and dampness can be health hazards; keep dated photos and a written log of complaints, and send them to your landlord. If the issue isn’t addressed promptly, you can file a formal complaint with the Régie du logement.

Understanding Mold and Infestation Problems

Mold thrives in damp environments and can cause respiratory issues and other health concerns. Infestations of pests such as bedbugs, rodents, and cockroaches can disturb daily life and contribute to unsanitary conditions. It's essential for tenants to address these problems promptly to ensure a safe living environment.

Identifying Mold and Infestations

  • Mold: Visible patches of black, green, or white fungi, often accompanied by a musty odor.
  • Pests: Signs include droppings, bite marks, nests, or insect sightings within the rental unit.

Tenant Rights and Responsibilities

In Quebec, tenants have the right to live in a safe and properly maintained environment. It's the landlord's responsibility to ensure the property is habitable and free from health hazards. Tenants should promptly report any issues to the landlord in writing. The Emergency Situations and Repairs: Tenant Rights and Responsibilities offers more details on how to handle urgent repairs.

Always document all communications with your landlord in writing and keep copies of every message. If you haven't received acknowledgment of your request, follow up and keep a record for potential disputes.
