How Tenants Can Handle Neighbour Complaints About Pets or Smoke in Ontario

Utilities & Services Ontario published: June 10, 2025 Flag of Ontario

Sharing a rental property in Ontario sometimes means differences in lifestyle can lead to neighbour complaints, especially about pets or smoke. If you’re facing these issues, understanding your rights and responsibilities under Ontario law can help you resolve disputes calmly and protect your tenancy.

Ontario Tenants: Your Rights and Responsibilities With Pets and Smoke

In Ontario, both tenants and landlords must follow the Residential Tenancies Act, 2006 [1]. Let’s look at what this means if you’re receiving complaints:

  • Pets: Most leases cannot prohibit pets. However, if your pet is disturbing others or causing damage, action may be required.
  • Smoke (Tobacco, Vaping, Cannabis): Tenants can generally smoke in their unit unless the lease prohibits it. However, causing excessive smoke or odours can breach your obligation not to disturb others.

Both pet ownership and smoking involve balancing personal freedoms with your neighbour’s right to reasonable enjoyment of their home.

Common Types of Complaints

Neighbour complaints about pets and smoke often fall into these categories:

  • Noisy or aggressive pets disturbing others
  • Pets causing allergies or damage in common areas
  • Strong odours from pets or smoking entering neighbouring units
  • Cigarette, cannabis, or vape smoke affecting shared spaces

How Complaints Are Handled: The Process in Ontario

Neighbour complaints can be informal (verbal or written) or formal (involving your landlord or the Landlord and Tenant Board (LTB)). Here’s what tenants should know about the process:

  • Your landlord must balance the rights of all tenants. If a complaint is made, your landlord may first try to resolve things informally.
  • Your landlord must investigate and cannot take retaliatory action without proof.
  • If issues persist, landlords may serve you an official notice using Form N5: Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding.

If you receive a formal notice, you have a chance to correct the problem. Unresolved issues can lead to a Landlord and Tenant Board hearing.

Responding to Complaints: Step by Step for Tenants

If you receive a complaint about your pet or smoke, taking prompt actions can help avoid further problems:

  • Communicate calmly with your landlord and neighbours. Ask for details and clarify the problem.
  • Try to resolve issues amicably, such as using air purifiers, not smoking near windows, or keeping your pet quiet indoors.
  • Document any requests and your responses in writing.
  • Review your lease to check for pet or smoking rules.
  • If necessary, seek help from tenant support organizations or legal clinics.
If you address a complaint within 7 days of receiving a Form N5, the notice is void and you cannot be evicted for that reason this time.

Understanding Form N5: Notice to End Your Tenancy for Interfering with Others, Damage or Overcrowding

When is Form N5 used?
Form N5 (official source) is served by the landlord if your behaviour (or your pet/smoke) substantially interferes with another tenant’s enjoyment of the property, causes damage, or leads to safety concerns.

  • Example: If your neighbour complains of persistent loud barking, and your landlord documents this, they may give you a Form N5.

What can you do?

  • Read the form carefully—it includes the reason and evidence for the complaint.
  • You have 7 days to fix the problem, such as reducing noise or containing smoke.
  • If corrected, the N5 is void. If not, your landlord may apply to the Landlord and Tenant Board of Ontario.

If You Disagree With a Complaint

It’s important to know that tenants have the right to challenge complaints that are untrue or unfair:

  • Respond in writing, stating your side with any supporting details (e.g., vet records for a quiet pet, medical note for therapeutic animals, logs of efforts to reduce smoke).
  • Attend any LTB hearing to present your evidence.
  • Consider seeking legal help or advice if you're unsure. How to Handle Complaints in Your Rental: A Tenant’s Guide provides more tips.

Health and Safety Concerns

If smoke or pet allergens are affecting your health, you may also have grounds to request landlord intervention. Learn more about Health and Safety Issues Every Tenant Should Know When Renting.

FAQ: Pets, Smoking, and Neighbour Complaints in Ontario Rentals

  1. Can my landlord evict me if my pet bothers a neighbour?
    Landlords must follow a process—if your pet causes substantial disturbance, you may receive a Form N5, with a chance to fix the issue. Eviction only occurs if the problem continues and the Landlord and Tenant Board agrees.
  2. What if the complaint about smoke is false or exaggerated?
    If you believe a complaint is inaccurate, respond in writing, provide evidence, and be prepared to explain your side at an LTB hearing if needed.
  3. Is a "no pets" clause enforceable in Ontario?
    Generally, no. Ontario law invalidates most “no pets” clauses, except in some condominiums or special housing.
  4. Can I smoke in my rental unit?
    It depends on your lease. Smoking is allowed unless prohibited by the lease, but you must not disturb other tenants or damage the property.
  5. What should I do if I'm allergic to a neighbour's pet or smoke?
    Inform your landlord in writing, ask for reasonable accommodations, and engage in problem-solving discussions. See the health and safety resources for further steps.

Key Takeaways for Tenants Facing Neighbour Complaints

  • Communicate and try to resolve minor issues informally.
  • Understand and respond quickly to official notices such as Form N5.
  • Your rights as a tenant are protected under Ontario law, but so is your neighbour’s right to peaceful enjoyment.
  • Keep written records of complaints and your responses.

Addressing complaints promptly and respectfully is the best approach to long-term harmony in your rental home.
