Smoking and Cannabis in Ontario Rentals: Landlord and Tenant Rules

Ontario Smoking & Cannabis Rental Guide · Updated for 2026

Smoking and cannabis issues in Ontario rentals can involve the tenancy agreement, condominium rules, municipal bylaws, provincial smoke-free legislation and a tenant’s reasonable enjoyment of the property.

Can a Lease Restrict Smoking?

A tenancy agreement can include smoking rules. The Ontario Standard Lease has a section for smoking terms. Landlords should state restrictions clearly rather than relying on informal expectations.

Cannabis Is Not Automatically Treated Differently

Legal cannabis does not create an unrestricted right to smoke anywhere. Lease restrictions, condominium rules, smoke-free laws and interference with other occupants can still matter.

Smoke and Reasonable Enjoyment

Where smoke or odour substantially interferes with another tenant’s reasonable enjoyment, the landlord may need to investigate. Documentation should focus on dates, duration, location and impact rather than assumptions about the source.

Medical and Human-Rights Issues

Some situations can engage disability-related accommodation obligations. That does not necessarily mean every requested smoking method or location must be accepted, but landlords should avoid making decisions without considering applicable human-rights duties.

Practical Steps

• Put smoking rules in the lease.
• Provide applicable condominium rules.
• Document complaints objectively.
• Investigate ventilation and building issues where relevant.
• Consider accommodation obligations before taking enforcement action.
