Welcome to Canada's first fully online tribunal! The Condominium Authority Tribunal, or the CAT, is an online tribunal that helps to resolve and decide 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.
