The Condominium Authority Tribunal (CAT)
The CAO will soon be undertaking a consultation about opportunities to expand the CAT’s jurisdiction. Check back soon for more details.
The Condominium Authority Tribunal (CAT) is Ontario’s first fully online tribunal! The CAT uses an online dispute resolution system (CAT-ODR) to help people resolve certain types of condominium-related disputes conveniently, quickly, and affordably.
The CAT’s 3-stage dispute resolution services are offered at a total cost of $200 ($25 for Stage 1 – Negotiation; $50 for Stage 2 – Mediation; and $125 for Stage 3 – Adjudication).
