Quick answer: Usually, yes. Section 14 of Ontario’s RTA generally makes a tenancy-agreement term prohibiting animals in or around the rental complex void. But that does not give every animal unrestricted protection: enforceable condominium rules, serious allergies, dangerous behaviour, damage and substantial interference may still matter.
A “no pets” clause in a lease is generally unenforceable under section 14. A landlord may still ask about pets during screening, subject to human-rights law, and may decide not to enter into a tenancy for lawful reasons before an agreement is formed.
After the tenancy begins, any response should focus on the actual legal issue—not merely the existence of the pet.
What if the rental is a condominium?
A condominium declaration or rule may restrict certain animals, sizes or numbers. Condo obligations can apply to tenants even where the landlord’s own lease clause would be void. The exact governing documents should be reviewed.
What if another resident has an allergy?
A serious allergy may require evidence and a careful accommodation analysis. The result is not automatic; severity, proximity, ventilation and possible solutions may matter.
Can a problem pet lead to eviction?
Potentially, if reliable evidence establishes substantial interference, danger, serious allergic reaction, damage or another statutory ground. The landlord must use the proper notice and LTB process.
What should the tenant do?
- Review condominium documents and municipal animal bylaws.
- Prevent noise, waste, damage or safety problems and respond promptly to complaints.
- Keep veterinary, licensing and training records where relevant.
- Request disability-related accommodation in writing when applicable.
What should the landlord do?
- Do not treat a void lease clause as an automatic eviction right.
- Investigate specific conduct, damage, allergies or rules and keep reliable evidence.
- Consider human-rights accommodation duties, including service animals.
- Use the correct LTB notice and process where a statutory ground exists.
Example
A lease says “no pets,” but the tenant adopts a quiet indoor cat and no condo rule or actual problem applies. The clause alone is generally void. A dangerous dog repeatedly threatening residents presents a different issue.
