Condominium Authority Tribunal Application Checklist: Noise, Odour, Light, Vibration, Smoke and Vapour

Our Solving Common Issues pages contain important information about how to resolve condo living issues before they escalate. 

Your application must deal with noise, odour, light, vibration, smoke, vapour as these are within the CAT’s jurisdiction as per Ontario Regulation 179/17

Go back to the previous page and try to file a different kind of application if your issue is about:

• Condo Records
• Pets and Animals
• Vehicles
• Parking
• Storage
• Another type of nuisance set out under your corporation’s governing documents
• Compliance with settlement agreements.

Read about our jurisdiction to learn more.

The governing documents are the condo corporation’s declaration, by-laws and rules.

You can file by yourself or jointly with another applicant as long as you confirm with them that are willing to participate in the case.

Each applicant will need their own CAO account and will need to participate in the case either directly or through a representative. 

Respondents are the parties you are filing against.

You must provide the name and address for each respondent you identify.

You should also determine if the respondent is a unit owner, tenant or guest by asking your condo for their Record of Owners and Mortgagees or Record of Notices Relating to Leases of Units.

Respondents must be notified about your application so they can join the case and respond to the issues you are raising. The CAT may issue an order without them if they refuse to join.

An Intervenor is any party that can participate in a CAT case, as set out under Rule 15 of the CAT’s Rules of Practice.

Applicants must identify all intervenors when filing their application.

Who can intervene depends on three factors:

• Who filed the case
• The reason it was filed
• Who the respondent is

Read the CAT’s Guide to Respondents and Intervenors for more information.

Speaking to the parties before filing may lead to resolving the issues collaboratively and saving all parties time and money.

The CAT may consider whether you tried to resolve the dispute or explore lower cost alternatives when issuing the final order in Stage 3 – Tribunal Decision. 

The CAT can only accept applications that deal with issues that occurred within the last two years, as set out in the Condo Act.

A CAT Member may grant an extension if your issue occurred between two and three years ago. The CAT cannot grant extensions for disputes that occurred more than three years ago.

Extensions are not guaranteed. If the CAT does not grant you an extension, your $25 application filing fee will not be refunded.
