Steps to Join a CAT Case
Before you do anything else, you should first determine who will be joining the case. The person who joins the case must have the authority to act on the behalf of the condo corporation and must have enough information about the issues to be able to participate in the dispute resolution process.
A condo corporation can have a director or a manager join the case, or you can have a lawyer or paralegal join on the condo corporation’s behalf.
The CAT strongly recommends that the condo corporation’s board of directors jointly discuss and decide who will join on behalf of the condo corporation.
If you are a unit owner or Occupant
You can either join the case yourself, or have a lawyer, paralegal, or other representative join on your behalf.
