The Condominium Authority Tribunal (the CAT), is an online tribunal dedicated to resolving and deciding condominium-related disputes in Ontario.  The CAT has developed an online dispute resolution system (CAT-ODR) to help people resolve their disputes conveniently, quickly and affordably, while encouraging everyone to work together in healthy condominium communities.

Account Requirements

You must have a personal account on the CAO website to file or join a CAT application.
If you already have an account (e.g., because you created one to access the CAO’s other services, such as the CAO’s online Director Training Program), you can use that account to file or join a CAT case.
