Smoking and Cannabis Rules in Shared Units Quebec

Shared housing raises clear questions for renters about smoking tobacco, vaping, and using cannabis inside common areas and multi‑unit buildings in Quebec. This guide explains tenant options, what landlords can include in leases, and how provincial and federal rules interact so you can protect your health and housing. It offers plain steps for documenting problems, filing an official complaint, and asking the Tribunal for help if needed. Wherever possible, we use practical examples for tenants who share kitchens, hallways, or suites and point to the official sources and forms you may need in Quebec.

How smoking and cannabis rules work in Quebec

Quebec law and federal rules both affect where smoking and cannabis consumption are allowed. Landlords can include reasonable clauses about smoking in leases, but clauses cannot conflict with the Civil Code of Quebec or public health laws. If a building has a no‑smoking policy in common areas or inside units, that policy should be written and shared with all renters. If use creates odours, residue, or health concerns, tenants can raise the issue with their landlord and, if unresolved, apply to the Tribunal administrative du logement for a ruling.^[1][2]

Common lease clauses and what they mean

• Clauses that require tenants to avoid smoking or using cannabis inside the unit or common areas should be written and signed in the lease.
• Landlords may set rules to protect habitability and health, such as bans in hallways, stairwells, or indoor shared spaces.
• If smoke or residue causes damage, the lease may allow deductions for repairs if the landlord documents and proves the cost.

What tenants can do if smell or smoke affects their unit

Follow a stepwise approach: tell the other tenant or landlord in writing, document dates and effects, request reasonable remedies, and keep records. If that fails, you can file an application with the Tribunal administrative du logement for nuisance, repairs, or lease enforcement.^[1]

• Send a written notice to the landlord describing the problem and the remedy you want, and keep a copy.
• Collect evidence: photos of damage, dated notes of odour occurrences, and statements from neighbours.
• Note deadlines in responses: if a landlord agrees to act, get the expected timeline in writing.

When public health and legislation apply

The federal Cannabis Act regulates legal possession and sale, while Quebec law and public health rules set where consumption is permitted. Municipal bylaws may also limit smoking in certain outdoor or common places. If you believe smoking or vaping creates a health hazard (for example second‑hand smoke affecting allergies or asthma), reference public health guidance when discussing the issue with your landlord.^[3]

Filing a dispute with the Tribunal administrative du logement

Before applying to the Tribunal, try to resolve the issue directly. If that fails, you can file an application outlining the nuisance, the clauses you rely on, and the remedy you seek. Include copies of your lease, written notices, and any evidence. The Tribunal will set a hearing where both sides can present records and testimony.

Practical example

If cigarette smoke from a neighbouring unit seeps into your bedroom and aggravates your asthma, send a written request to the landlord asking for intervention. If no action follows, file an application to the Tribunal with your evidence and ask for either enforcement of a no‑smoking clause or an order for remediation and repairs.
