Living with cannabis smoke in a rental can be stressful and affect your health, sleep, and comfort. If you rent in Ontario, you have rights to reasonable enjoyment, safety, and a habitable unit under provincial rules. This guide explains what to document and why evidence matters, how to raise a written concern with your landlord, what mitigation options to request (for example, sealing gaps or improving ventilation), and when to ask for a hearing at the Landlord and Tenant Board. It includes sample actions, suggested timelines, and links to official forms and legislation so tenants can act confidently and protect their health at home.
What the law says
Ontario tenants are protected by the Residential Tenancies Act, 2006, which recognizes a tenants right to reasonable enjoyment of the rental unit and requires landlords to maintain a unit in a good state of repair and fit for habitation[1]. The Landlord and Tenant Board is the tribunal that hears many tenancy disputes, including issues where smoke or odours interfere with reasonable enjoyment[2].
Practical steps to address cannabis smoke
Follow a clear, tenant-focused process so you preserve evidence and meet deadlines.
- Keep clear records: photos, notes, and logs of each exposure with what you smelled and how it affected you.
- Give written notice to your landlord describing the issue, the dates, and the action you request (for example, sealing gaps or improved ventilation).
- Request mitigation measures such as sealing cracks, weatherstripping, upgraded ventilation, or approved air purifiers to reduce smoke transfer.
- Ask for a hearing at the Landlord and Tenant Board if the problem continues and informal requests do not resolve the interference with your enjoyment.
- Consider moving out if exposure cannot be stopped and you need a healthier space; you can Find rental homes across Canada on Houseme while you plan next steps.
When you write to the landlord, be specific and courteous: state the impact (sleep, health, guests), include dates and times where possible, and offer practical fixes. Keep copies of all messages.
When to involve officials or public health
If the smoke causes real health problems (asthma attacks, headaches, nausea), mention health impacts in your written communications and seek medical advice. Public health units can advise about exposure risks, but most tenancy remedies go through the Landlord and Tenant Board.
How to prepare for a Landlord and Tenant Board hearing
If you apply for a hearing, arrive prepared with organized evidence and a clear timeline.
- Bring photos, dated logs, and copies of written notices you gave the landlord.
- Bring any written responses from the landlord, including offers to fix the issue or refusal.
- List any neighbours or witnesses who can confirm the smell or frequency of exposure.
