Many tenants and renters in Quebec share walls, hallways and ventilation with neighbours, and cannabis smoke can cause nuisance or health concerns. This guide explains what renters can do if odours enter their unit, how to document incidents, what clauses landlords may include in leases, and when to contact the Tribunal administratif du logement (TAL).[1] It covers practical steps for communicating with neighbours and landlords, filing a complaint, and which official forms and evidence help a case. You will also learn about reasonable accommodation for medical cannabis, building-wide smoking policies, and timelines for notice and hearings so you can protect your home and health without escalating conflict.
What Quebec law says about smoking cannabis in buildings
In Quebec, tenancy obligations and lease terms are governed primarily by the Civil Code of Québec and interpreted by the Tribunal administratif du logement. A landlord may include a no-smoking clause in a lease that covers tobacco and cannabis, but any clause must respect the Civil Code and rights to a safe, habitable dwelling.[2] Where smoke creates health or habitability problems, tenants can seek remedies through communication, remediation requests, or an application to the Tribunal.
Common tenant steps if smoke affects your unit
- Document every incident with dates, times, photos or video and a short written log.
- Talk to the neighbour directly and calmly where it feels safe, and explain the problem and times when smoke entered your unit.
- Send written notice to your landlord describing the issue, the dates and the remedy you request; keep a copy.
- Request practical remediation from the landlord (seal gaps, improve ventilation, install door sweeps or air purifiers) to reduce smoke transfer.
- If the problem continues, consider filing an application with the Tribunal administratif du logement for an order or remedy.
What the Tribunal handles and official forms
The Tribunal administratif du logement hears disputes about lease terms, nuisance, repairs and requests for rent adjustments or lease termination. The TAL website publishes official forms and guides for tenants and landlords, including how to file an application and what evidence to bring. Use the Tribunal's forms page to find the right application and follow the filing instructions exactly.[1]
- Application to the Tribunal (tenancy dispute): used when you request a decision about nuisance, lease interpretation, or obligations.
- Urgent or interim request: used when you need a quick order to stop ongoing harm (for example, severe health impacts from smoke).
- Evidence list and attachments: provide your log, photos, videos and any medical notes that support your claim.
Effective communication and reasonable accommodation
If medical cannabis use is involved, tenants may request reasonable accommodation under human rights obligations. Accommodation requests should be written, explain the medical need (supporting documentation where appropriate), and propose practical steps that limit smoke transfer to others. Landlords and tenants should aim for solutions that balance health, safety and legal obligations.
