Joining a Case: FAQs


Steps to join a case

Step 1. Determine who will join

Before you do anything else, you should first determine who will be joining the case on behalf of the condo corporation. If you haven’t already discussed this, you should probably talk to the condo corporation’s board of directors. The person who joins the case must have the authority to act on behalf of the Respondent, and must have enough information about the issues to be able to participate in the dispute resolution process.

Step 2. Create an account or log in

First, you must log into an existing CAO account, or create a new account.

If you don’t yet have an account or you need to login, click the “Login” button at the top of the page.

If you are creating a new account, make sure you remember your username and password.

Important:  If you are a condominium manager or a member of a condominium corporation’s board of directors, you must use your account that is associated with the CAO’s condominium corporation profile. For more information, please visit our  Filing or Joining a Case as a Director or Manager page .

The next step is to identify your role in the case.

  • If you are a lawyer or paralegal, you must select “Myself”
  • If you are a condo manager or director, you must select Representative of a condo corporation (Manager or Director). Once you make this selection, it is very important that you select the right condo corporation from the drop-down that will appear. Once you have selected the right condo corporation, click “Next”.

Step 5. Provide the Code and Date from the Notice

Next, you will be asked to provide the code and date included in the Notice. Enter the code and date exactly as they appear and ensure that there are no extra spaces. Each code is unique and can only be used once.

Step 6. Confirm the Respondent’s Information

Next, you will be asked to confirm the Respondent’s contact information. The information you see on this screen was provided by the Applicant when they first filed. You need to confirm the condo corporation’s email address and provide the condo corporation’s mailing address.

Step 7. Provide your Own Information

The next step is to provide details about the representative. If you are the representative, enter and confirm your own contact information, and the system will automatically add you to the case and move the case into Stage 1 – Negotiation.

After you’ve confirmed your own information, you will be automatically added to the case and the case will move to Stage 1 – Negotiation.

Note : You only need to join the case once. Once you’ve joined, you can access the case by logging into your account on the CAO’s website, clicking on the “Tribunal” drop-down menu, and clicking “Access an existing tribunal case.”
