How to Prepare Evidence for CAT Ontario Cases

The Notice of Case arrives, and the director who sent the first compliance letter is away. Another director has a few photos on their phone. The delivery record is somewhere in an email thread. The owner says they were singled out and never received anything. This is the moment to prepare evidence for CAT Ontario, not by recreating a story from memory, but by assembling the record your board actually made.

For a self-managed corporation, the goal is not to produce the largest file. It is to produce a clear, chronological file that lets a Tribunal member see the issue, the governing document, the notice process, the owner’s response and the board’s decisions without having to guess.

Start with a usable compliance letter

A compliance letter is often the first document that connects a reported problem to the corporation’s declaration, by-laws or rules. It should be calm, specific and capable of standing beside the supporting material later.

Here is a practical starting point. Adapt it to the corporation’s own governing documents and the facts of the matter.

> Subject: Request for compliance - [unit number and issue] > > Dear [unit owner name], > > The corporation has received and documented concerns regarding [brief factual description, including date and location]. The concern relates to [quote or identify the relevant declaration provision, by-law or rule]. > > The corporation asks that the issue be corrected by [date]. Attached are the records currently relied upon, including [photographs, incident notes or other material]. > > Section 117 of the Condominium Act, 1998 prohibits conditions or activities likely to cause damage to property or injury to an individual. Section 119 requires each owner to comply with the Act, the declaration, the by-laws and the rules. > > If you disagree with the facts or believe there is relevant information the board should consider, please provide your written response by [date]. The board will review it before deciding on any further step. > > Sincerely, > > [Name and role], for the board of directors

This is not a finding of wrongdoing, and it should not read like one. Do not make broad allegations where the record supports only a narrow observation. If the concern is a repeated noise issue, identify dates, times, reports and the applicable rule. If it concerns damage, identify the observed condition and preserve photographs taken at the time.

The corporation cannot levy fines. Where its declaration contains indemnification provisions, the question of cost recovery is separate and should be considered carefully with the declaration and legal advice where needed. Do not turn a compliance letter into a demand for amounts the corporation has not properly established.

The file to prepare evidence for CAT Ontario

Build one chronological record, beginning before the dispute. A folder of screenshots and forwarded emails may contain the facts, but it forces the reader to reconstruct the timeline. A short index at the front solves that problem.

Your index can be as simple as a table with the date, document name, source and why it matters. Number every document consistently: A-1, A-2, A-3, and so on. If a photo is referred to in a letter, use the same identifier in both places.

The core file usually includes the following six groups of records.

1. The governing authority

Include the relevant pages of the declaration, by-laws and rules, not just a paraphrase. Highlighting can help, provided the original page remains readable. If the issue involves a rule, include evidence that the rule was properly made and communicated. Section 17(3) of the Condominium Act, 1998 sets out the corporation’s duty to enforce the Act and its governing documents.

Do not include an entire declaration simply because it exists. Include the provisions in issue and enough surrounding text to make their meaning clear.

2. The factual record

Use dated photographs, reports, correspondence and contemporaneous notes. For photographs, retain the original file where possible. A photo without a date, location or explanation may still be useful, but it carries less context than a photo recorded when the observation was made.

For each incident, record what was seen or reported, when, where, and by whom. Keep observation separate from conclusion. “Photo taken at 7.15 pm showing items stored in the corridor” is a record. “Owner ignored the rules” is an argument, and may not be supported by the facts.

3. Notices and proof of delivery

The question “I never got the letter” is common because it is simple to raise and difficult to answer from an inbox. Keep the final version of every letter, its attachment list, the sending date, recipient address and delivery evidence together.

The right delivery method depends on the declaration, by-laws, applicable notice provisions and the type of notice. Keep the practical proof: an email sent record, registered post receipt, courier confirmation, portal notification or an acknowledgement from the recipient. Do not rely only on a director’s recollection that they sent it.

Changes to notice compliance expected on 1 July 2027 make a disciplined delivery record even more worthwhile. Your corporation should confirm its process against the law and its own documents as that date approaches.

4. The owner’s response

Include every meaningful response, including replies that arrive by text message or through a director’s personal email. Preserve the full exchange, not only the sentence that supports the corporation’s position.

If the owner offers an explanation, proposes a remedy or raises a procedural concern, show what the board did with it. A file is stronger when it demonstrates that the board invited a response and considered it. It also helps distinguish an unresolved factual disagreement from an allegation of selective enforcement.

5. Consistent enforcement records

Selective enforcement allegations are rarely answered by saying “we treat everyone fairly”. They are answered with records. If similar issues have arisen elsewhere, locate the relevant compliance steps, while protecting personal information that is not necessary for the proceeding.

Consistency does not mean every situation receives identical treatment. The facts may differ: the rule may have changed, the evidence may be different, or an owner may have corrected the issue after the first letter. Record those differences. A fair process is one the board can explain with dates and documents.

6. Board decisions and authority

Keep the meeting agenda, minutes or written resolution that shows the board considered the matter and authorised the next step. Section 55 addresses records of the corporation, including minutes of board meetings. Good minutes do not need to reproduce the debate. They should show the decision, the authority for it and any direction given.

Where the issue may move beyond correspondence, preserve the full decision trail. Section 132 concerns mediation and arbitration in certain disputes, while section 134 deals with court applications for compliance orders. CAT jurisdiction depends on the subject of the dispute, so confirm the proper forum before assuming CAT will decide every condominium disagreement.

Make the chronology easy to test

Before filing or responding, ask a director who did not handle the matter to read the index and chronology. Can they answer five questions quickly?

What happened? Which provision applies? What did the corporation send? How was it delivered? What did the owner say and what did the board decide?

If the answer to any question requires searching multiple inboxes, the file needs work. This review often exposes gaps early: a missing attachment, an undated photo, a letter saved only as an editable draft, or a decision that was discussed but never recorded.

Keep originals and working copies separate. Do not overwrite a photo, edit the body of a sent email, or replace an earlier letter with a revised version. If a correction is necessary, add a dated explanatory note. The point is not perfection. It is an honest record that shows how the board handled the issue at the time.

CAT filing stages can total $200. For a volunteer board, the larger cost is often the evenings spent hunting through private inboxes, rebuilding a timeline and trying to remember why a decision was made. Preparing the file while events are current is usually less demanding than preparing it after a Notice of Case arrives.

Keep the record in the corporation’s hands

A shared spreadsheet, Word templates and email folders can work for a small corporation until a director resigns or correspondence starts arriving across several channels. The risk is not merely untidiness. It is that the corporation’s record becomes dependent on one person’s Gmail account or phone.

YardRule is built for self-managed Ontario condominium corporations to keep this specific compliance record together: GPS- and timestamped photos, compliance letters, delivery tracking, owner responses, escalation reminders, meeting packs and an append-only history. The record remains readable and exportable if the corporation stops paying. It is $49 per month for up to 25 units, or $99 per month for up to 100 units, with a 30-day full-product pilot and no credit card.

Whatever system your board uses, give the secretary and at least one other director access, agree on file names, and store the final record where future boards can find it. The better file usually wins attention because it makes the board’s process understandable before anyone has to explain it.
