The CAT-ready evidence package: assembling your board's case file

What “CAT-ready” actually means

CAT cases are conducted online, in writing, through the Tribunal’s dispute-resolution system. If a case reaches Stage 3, a Tribunal member decides it on the uploaded documents and written submissions. Nobody testifies in a courtroom. Nobody reads your treasurer’s sincere face. “CAT-ready” therefore means one thing: a stranger with no knowledge of your building can open your package, follow the story in order, and find a document behind every sentence of it. That standard is worth aiming at even for disputes that settle at Stage 1 or 2, because the side that shows up organized settles from strength.

The package inventory

Assemble these six components. Most boards discover the gaps in the list only when they try to produce it, which is the argument for trying before anyone files.

• A one-page chronology. Every event in the matter, one line each, dated: observation, complaint received, board discussion, letter sent, delivery confirmed, deadline passed, re-inspection. This is the first page a Tribunal member should see. Each line should point at a document later in the package.
• The governing provisions, quoted. The exact sections of the declaration, by-laws or rules the corporation relies on, quoted in full with their section numbers, plus any provision the corporation relies on when it asks for costs. Not the whole declaration; the operative paragraphs.
• Dated evidence of the conduct. Photos, videos, noise logs, inspection notes, each carrying the date it was captured. Multiple dates prove a pattern; one undated photo proves almost nothing.
• Every notice, with proof of delivery. Each compliance letter as sent, paired with its delivery record: email delivery confirmation, registered mail receipt, or a dated note of personal delivery. “I never received it” is the oldest defence in condo disputes, and a delivery record is the only answer that works.
• The owner’s side. Their replies, their complaints, any accommodation request and the board’s response to it. Including the other side’s correspondence is not a concession; a package containing only outbound mail reads as a campaign, and Tribunal members notice.
• Minuted board decisions. The minutes showing the board, as a board, reviewed the matter and decided to act. This is what proves the corporation enforced its rules deliberately rather than one director pursuing a neighbour.

Order and labelling: make the reader’s job easy

Arrange everything chronologically behind the one-page chronology, and label each document the way the chronology refers to it. A Tribunal member who can verify your timeline in ten minutes starts from trust. One who has to reconstruct the story from a folder of unlabelled photos and email screenshots starts from irritation, and irritation is not a neutral starting point. If a document needs context a stranger would lack, add one plain sentence above it, not an essay.

What weakens a package

• Reconstructed records. A tidy log typed the week before the hearing, in one sitting and one font, gets the weight it deserves. Records earn trust by existing before the dispute did, mistakes and all. If an original entry was wrong, add a dated correction; never rewrite it.
• Missing delivery proof for one letter in the ladder. Escalation depends on the owner having received each prior step. One unproven letter can collapse the sequence built on it.
• Silent gaps. A complaint in January and the next document in September invites the inference that the board did not treat the issue as serious. If there is an innocent explanation, the chronology should state it.
• Evidence of inconsistent enforcement. If the owner can show other units doing the same thing without letters, the case becomes about the board’s fairness. That risk is built long before the hearing; our selective-enforcement guide covers it.

The Tribunal’s reach is growing

Ontario’s condo rules are changing in stages. From December 31, 2026, new rules govern how owners requisition meetings. From July 1, 2027, the Condominium Authority Tribunal can also hear disputes about owners’ meetings, including whether notices of meetings went out on time with the required content, and the most it can award in damages rises from $25,000 to $50,000. None of that changes how compliance disputes are decided today; it widens the set of board decisions that can end up in front of a Tribunal member reading documents. A corporation whose records live in a director’s personal inbox is exposed under the current rules and has more to answer for under the coming ones. The package described above is the habit that serves a board in both.

An afternoon or a month

Here is the practical test of your corporation’s records: could you assemble this package for your most contentious open issue in an afternoon? Boards that keep one file per issue, attach evidence as it is gathered, and record delivery for every notice can. Boards reconstructing from three inboxes, a shared drive and a binder in the president’s hall closet need weeks, and the package still comes out with gaps. The time to find out which board you are is before the $25 filing fee lands.
