The issues that the CAT that can be filed with the are prescribed under Ontario Regulation 179/17, which is a regulation under the Condominium Act, 1998.

That means you can only file an application with the CAT if your dispute relates to one of the dispute types listed above. This is because of sections 1.36 and 1.47 of the Act.
