The Condominium Authority Tribunal: What It Can Decide

Many condo disputes now go to an online tribunal instead of court. Here is what the Condominium Authority Tribunal can decide.

The Condominium Authority Tribunal (CAT) is an online tribunal for certain disputes between condo owners, occupants and condo corporations in Ontario.

The short answer

The CAT hears disputes about condo records and about provisions in the declaration, by-laws or rules on pets, vehicles, parking, storage, and nuisances such as noise, odours, smoke, vibration and light, plus some other issues. Most cases are handled online.

What it can decide

  • Records: requests to see a condo's records
  • Pets and animals
  • Vehicles, parking and storage
  • Nuisance and annoyance: noise, odours, smoke and vapour, light, vibration
  • Indemnification and compliance issues connected to these disputes

What it can't decide

  • Most disputes about repairs, common element maintenance or construction defects, which usually go to court.
  • Disputes outside its jurisdiction.

How it works

  1. Negotiation online between the parties.
  2. Mediation with a CAT mediator.
  3. Adjudication: a member decides and can make binding orders.

Costs

Filing fees are modest, and the CAT can order costs.

Tips

  • Gather the declaration, by-laws and rules.
  • Keep records of every incident, with dates.
  • Try to resolve the issue with management first.
