Living with mould or persistent dampness can threaten your health and your right to a habitable home. If you rent in Quebec, you have specific tenant protections and practical steps you can take to get repairs and reduce risk. This guide explains, in clear language, how to identify mould issues, when to tell your landlord, how to document problems, and how to use provincial processes if repairs are not made. It covers what evidence will help your case, which official tribunal or legislation to consult, and examples of forms and timelines so you can act confidently. The information is aimed at renters who want straightforward, practical advice to keep their home safe and maintain their legal rights in Quebec.
Why mould and dampness matter
Mould and ongoing dampness can cause or worsen respiratory problems, allergies, and other health concerns. Damp conditions also damage finishes, insulation and structural elements, making a home less safe and less valuable over time. Tenants do not need to accept hazardous conditions: most rental rules require landlords to provide and maintain a dwelling that is safe and fit to live in.
Recognizing mould and common causes
- Visible black, green or grey spots on walls, ceilings or window frames.
- Musty or persistent damp smells in closets, bathrooms or basements.
- Peeling paint, bubbling wallpaper or condensation on windows.
- Recurring leaks from plumbing, roof, windows or poor ventilation.
Your rights in Quebec
Under Quebec law a rented dwelling must be maintained in good condition and fit for habitation; tenants can ask for repairs and, if necessary, apply to the provincial tenancy tribunal for help. The Tribunal administratif du logement handles disputes about repairs, habitability and lease obligations [1]. The Civil Code of Québec sets the legal framework for leases and landlord obligations [2].
Relevant official forms and when to use them
- Written notice to the landlord — no formal government form is required for a first written request; send a dated letter or email asking for specific repairs and keep a copy. Example: "Please repair the bathroom exhaust fan to stop condensation" and keep proof you sent it.
- Application to the Tribunal administratif du logement — use the Tribunal's application process when repairs are not made or when you need a formal order. Example: if repeated requests were ignored, file an application to ask the Tribunal to order repairs or reduced rent [1].
- Medical or expert reports — while not a government form, a doctors note or indoor air assessment can be evidence for a Tribunal application. Example: attach a physicians note describing health effects from mould to strengthen your application.
Documenting problems and asking for repairs
Good documentation improves your chances of a quick resolution. Use dated photos, time-stamped videos and a short log of incidents and communications. When you write to your landlord, be clear about damage, what you want fixed and a reasonable deadline.
- Take clear photos of mould and damp areas, with dates noted in file names.
- Keep a short log of symptoms (health), dates of leaks or condensation, and any temporary measures taken.
- Save copies of messages, emails and receipts for remediation expenses if you had to pay for emergency fixes.
When to contact the Tribunal or seek other remedies
If the landlord does not respond or repairs are incomplete after you provide written notice, you can start a formal application with the Tribunal administratif du logement to request inspection orders, mandatory repairs or rent reduction. The Tribunal also handles urgent situations where health is at risk.
- After giving written notice and waiting a reasonable time, file an application with the Tribunal if repairs are not completed [1].
- For urgent hazards that affect health, note the dates and seek an expedited response through the Tribunal or health authorities.
- If you have immediate health concerns, consult a health professional and contact local public health services.
FAQ
- Can I withhold rent if my apartment has mould?
- Withholding rent is risky and generally not recommended; instead, give written notice asking for repairs and use the Tribunal to seek rent reduction or orders if the landlord does not act.
- How long should I give my landlord to fix mould?
- Give a reasonable written deadline depending on severity: a few days for leaks or serious health risks, and up to 10-14 days for non-urgent repairs, then consider applying to the Tribunal if there is no satisfactory action.
- Will the Tribunal order repairs or rent reductions?
- Yes. The Tribunal can order landlords to make repairs, set deadlines, and award rent reductions for loss of enjoyment or remedy costs when justified by evidence.
