Condo living adds a layer that most other Small Claims Court disputes don't have: a condominium corporation, a board, and a set of governing documents sitting between the people in the dispute. That layer also means condo disputes can end up in one of several different forums depending on exactly what they're about — getting this right before you file saves real time.
Two different forums, two different roles
Since 2017, Ontario has had a dedicated tribunal for certain condo disputes — the Condominium Authority Tribunal (CAT), part of the Condominium Authority of Ontario. CAT was built specifically around Condominium Act, 1998 governance issues, not general money claims — so for a condo-related dispute, the first real question is usually whether it fits CAT's specific list or not, rather than whether it fits Small Claims Court's general one.
What the Condominium Authority Tribunal generally handles
As of this writing, CAT's jurisdiction generally covers:
- Disputes over access to a condo corporation's records.
- Certain nuisances — noise, odour, light, vibration, and similar issues — where the condo's governing documents address them.
- Disputes over provisions in a condo corporation's governing documents dealing with pets and other animals, vehicles, and parking or storage.
- Compensation claims tied directly to the categories above.
- Disputes about whether a party complied with a CAT settlement agreement.
This list has changed before and may change again — confirm the current scope directly on the Condominium Authority of Ontario's website before deciding where to file.
What generally doesn't fit at CAT
Disputes about changes to common elements, general repair and maintenance disagreements, matters likely to cause injury or damage, and broader governance disagreements over board decisions generally fall outside CAT's usual scope. Depending on the specific claim, these may instead need to go to the Superior Court of Justice, or — where the dispute is genuinely a straightforward money claim within the monetary limit — Small Claims Court. This is exactly the kind of jurisdiction question worth confirming before you invest time preparing a claim; see can I sue? and the eligibility tool for a general check.
A condo corporation suing an owner
One of the more common condo-related Small Claims Court cases runs the other direction: the condo corporation pursuing an owner. Unpaid common expenses, or a specific charge-back cost the corporation is entitled to recover under its governing documents, can be pursued as a straightforward money claim — see how to sue someone in Ontario for the general filing process, and breach of contract for how an agreement-based claim like this is generally framed.
An owner pursuing a money claim against the corporation
Where an owner's dispute with the corporation is genuinely about money — for example, a specific, quantifiable loss not connected to the governing-document categories CAT handles — Small Claims Court may be the right forum once CAT is confirmed not to apply. Document exactly what was owed, what the corporation's own documents or bylaws say about it, and any communication with the board or property manager about the issue.
What to gather before filing
- The relevant sections of the condo corporation's declaration, bylaws, or rules.
- Any notice, invoice, or statement of account showing what's owed or disputed.
- Correspondence with the board, property manager, or condo corporation about the issue.
- Confirmation — in writing, if possible — of which forum your specific issue falls under, since this is the step most condo disputes get wrong first.
Common mistakes
- Filing at the wrong forum without first checking whether CAT's specific jurisdiction applies.
- Treating a repair or common-element disagreement as a simple money claim when it may actually require the Superior Court of Justice.
- Not reviewing the governing documents closely enough to know what the corporation is actually entitled to charge or recover.
- Waiting too long to address unpaid common expenses, letting the amount — and the dispute — grow.
Frequently asked questions
Can I sue my condo corporation in Small Claims Court?
Sometimes — it depends on what the dispute is actually about. A claim connected to the governing documents' rules on pets, vehicles, parking, storage, or certain nuisances generally belongs at the Condominium Authority Tribunal first. A money claim outside that list may fit Small Claims Court.
Can a condo corporation sue an owner in Small Claims Court?
Yes, this is one of the more common condo-related Small Claims Court cases — for example, pursuing unpaid common expenses or a specific charge-back cost within the court's monetary limit.
What does the Condominium Authority Tribunal actually handle?
Primarily records disputes, certain nuisances (like noise or odour where the governing documents address them), disputes over governing-document rules on pets, vehicles, parking and storage, and compliance with settlement agreements. Confirm the current list on the Condominium Authority of Ontario's own website before filing anywhere.
What about a dispute over common element repairs or a board decision?
These generally fall outside both Small Claims Court and the Condominium Authority Tribunal's usual scope and often require the Superior Court of Justice instead — this is exactly the kind of question worth confirming with a lawyer before you file anywhere.
