Mold Remediation: Landlord Liability and Fines Quebec

Tenants in Quebec who find mold should know their rights and practical steps to protect health and housing. Start by documenting visible mold, damp smells, and any health symptoms, then notify your landlord in writing with a clear request for repairs. Landlords in Quebec have a legal duty to keep rental premises in a habitable state; tenants can ask for urgent fixes, seek temporary measures, or apply to the provincial tribunal if problems persist. This guide explains how to document issues, use official forms and the Tribunal administratif du logement, when fines or orders are possible, and how to balance safety with staying housed while repairs are arranged.

What landlords must do about mold in Quebec

Landlords are required to maintain the rental unit in a condition fit for habitation and to repair issues that create health or safety risks. The Civil Code of Québec sets the legal duty for lessors to provide a habitable dwelling and to carry out necessary repairs to prevent damage or health hazards ^[2]. If a landlord does not act, the Tribunal administratif du logement (TAL) can order repairs, reductions in rent, or monetary compensation ^[1]. For a plain-language overview of obligations and practical responsibilities, see Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

How to document mold, ask for repairs, and use official forms

Clear documentation and timed communication are crucial. Record the problem, request repairs in writing, and allow reasonable access for inspection and remediation where required. If the situation affects health, mention symptoms and any medical notes when you communicate.

• Take dated photos and short videos, keep a written log of visible growth, moisture sources and any health symptoms, and save medical notes if relevant.
• Send a written repair request to the landlord by email or registered mail and keep proof of delivery; state what you want fixed and a reasonable deadline for action.
• Request professional remediation and repairs, and allow reasonable access for inspection when the landlord arranges qualified contractors.

Official forms and when to use them

When informal requests don’t produce results, there are official forms and procedures to escalate the issue. Below are common official resources tenants use in Quebec with practical examples for each.

• Application to the Tribunal administratif du logement (Demande au Tribunal) — Use when a landlord refuses to repair serious mold problems or when you seek rent reduction or compensation; for example, if mold makes a bedroom unusable for weeks, file an application asking the Tribunal for an order to repair and for an abatement of rent ^[1].
• Civil Code of Québec (statutory obligations for landlords and tenants) — Consult when you need to cite the legal basis for a repair request; for example, reference the lessor’s duty to maintain the dwelling when asking for remedial action ^[2].
• Quebec government: Mould and indoor air quality guidance — Official health advice about identifying and reducing exposure, useful when documenting health impacts and explaining urgency to your landlord ^[3].

What penalties and fines can landlords face?

The TAL can order landlords to make repairs and may award compensation to tenants for damages, rent reduction or reimbursement of remediation costs. In some cases, municipalities or public health authorities may issue orders or fines if building code or health regulations are breached. Tenants commonly ask the Tribunal for an order and reimbursement when repairs were refused and mold caused loss of use or health expenses ^[1].
