CAT Case File Guide for Ontario Condo Boards

A CAT Notice of Case can turn a routine compliance issue into several lost evenings for volunteer directors. The owner says the letter never arrived, questions why another unit was treated differently, or asks for every record behind the board’s decision. This CAT case file guide sets out the record to assemble before recollections fade and inboxes become the only source of truth.

The aim is not to create a large stack of documents. It is to create a clear, dated account: what happened, which provision applied, what the corporation communicated, how the owner responded, and what the board decided next. The better file usually wins because it lets the Tribunal understand the sequence without asking a director to reconstruct it from memory.

Start with a one-page case chronology

Before collecting attachments, make a chronology. It should fit on one page and use neutral language. Do not write that an owner was “difficult” or “clearly in breach”. Record observable events and the corporation’s actions.

A usable chronology might read:

> 12 March 2026: Director observed personal items stored in the common-element corridor outside Unit 14. Two photographs taken at 6:42 pm. > > 14 March 2026: Compliance letter sent to the unit owner by the delivery method required by the declaration. Letter referred to Rule 6 and requested removal by 21 March. > > 18 March 2026: Owner replied that the items were temporary and alleged that items outside Unit 9 had not received the same treatment. > > 19 March 2026: Director inspected the corridor outside Units 9 and 14. Photographs taken. Notice process started for Unit 9 based on the same rule. > > 24 March 2026: Board reviewed correspondence and photographs at its meeting. Board authorised a second compliance letter. > > 2 April 2026: Second letter delivered. Owner response received 5 April.

That format does two jobs. It shows whether the corporation acted consistently, and it separates fact from argument. If the chronology cannot identify the date, source, or person responsible for an entry, mark it as approximate rather than presenting it as certain.

CAT case file guide: the documents to collect

A case file should let another director, counsel, or an adjudicator find the original material behind every entry in the chronology. Start with these six groups of records.

• Governing documents: the relevant declaration provisions, by-laws, rules, and any properly adopted amendment. Include the version in force on the incident date, not just the latest copy saved in a shared drive.
• Evidence of the issue: dated photographs, videos where relevant, incident reports, contractor records, or contemporaneous notes. Preserve the original files where possible, including timestamps and location data.
• Communications: every compliance letter, email, portal message, and owner reply. Include attachments and keep them in date order.
• Delivery evidence: proof of how and when each notice was delivered, plus the address or email used. This matters when an owner says, “I never got the letter.”
• Board authority and decisions: meeting minutes, resolutions, or written director decisions that show who considered the matter and what was authorised. These should be proportionate to the issue, but they should exist.
• Comparable enforcement records: if selective enforcement is alleged, gather the same type of records for comparable units or incidents. Do not build a file around assumptions about what happened elsewhere in the building.

Use descriptive file names. “2026-03-14_Unit14_FirstComplianceLetter.pdf” is useful. “Final letter new version.docx” is not. A simple naming convention prevents the common problem where three directors each hold a different version of the same letter.

Match the record to the legal issue

The Condominium Act, 1998 supplies the framework, but the applicable documents depend on the dispute. Section 17(3) addresses the corporation’s duty to control, manage, and administer the common elements and assets. Section 119 requires owners to comply with the Act, declaration, by-laws, and rules. Section 132 concerns rules, including the process for making them.

For conduct or safety concerns, section 117 may be relevant. It prohibits a person from carrying on an activity in the corporation if it is likely to damage property or cause injury or illness to an individual. The evidence needs to support the actual concern. A general statement that conduct was “unsafe” is weaker than photographs, dated observations, reports, and a clear explanation of the affected area.

Section 55 matters where a dispute involves records. If an owner has requested records, keep the request, the corporation’s response, the records produced, any applicable fee notice, and delivery confirmation together. Record disputes can become confusing quickly when documents are spread across a former director’s email, a personal computer, and a paper binder.

Section 134 is relevant to court enforcement of compliance obligations in appropriate cases. It should not be treated as a standard threat in routine correspondence. The corporation’s declaration and the facts determine what steps are available. If legal enforcement or recovery of costs is being considered, obtain advice from the corporation’s counsel. Ontario condominium corporations cannot levy fines. Where the declaration contains appropriate indemnification provisions, the question may instead be cost recovery under those provisions.

Do not let selective enforcement become a memory test

Selective-enforcement allegations are often less about whether another breach existed and more about whether the board can show a consistent process. Boards do not need to prove that every past issue was identical. They do need to avoid relying on informal explanations such as “we dealt with that one years ago”.

Create a comparable-incidents note. State the relevant rule, the observed condition, the date it was identified, the notice issued, the outcome, and any material difference. A bicycle left briefly in a permitted location is not necessarily comparable to a storage locker placed in a fire route. The record should explain the difference without overstating it.

There is a trade-off here. Searching every old email can consume more time than the underlying matter warrants. Start with the period and locations identified by the owner, then expand only if the file suggests a broader pattern. Keep a note of the search performed. It is better to say what records were checked than to make a broad assurance that cannot be supported.

Prepare the file for CAT, not just for the board

CAT materials should be readable by someone who has never entered your building or attended your meeting. Number the pages or use a consistent exhibit label. Put the chronology first, followed by governing documents, communications, delivery evidence, photographs, and meeting records. Keep originals separately from the working bundle.

Avoid editing a photograph to add arrows or labels without retaining the original. If an annotation helps, make a separate marked copy and identify it as such. The same applies to email chains: preserve the complete thread, dates, sender details, and attachments rather than pasting selected wording into a new document.

The CAT’s filing stages total $200 for an applicant. That does not mean every disagreement should become a Tribunal dispute, nor does it mean the corporation should wait for a filing before organising its records. A calm, complete response record can clarify what remains disputed and may help the board make a measured decision about next steps.

Make the next file easier before the next notice arrives

The old method is familiar: a spreadsheet, Word letter templates, photographs on a director’s phone, and a conversation in email or WhatsApp. It can work until a director resigns, an owner disputes delivery, or the corporation needs the history on short notice. Then the board is not deciding the issue. It is searching for the file.

YardRule keeps a compliance record in one place with GPS-stamped photo capture, dated delivery records, owner responses, escalation reminders, meeting packs, and an append-only history. Its templates can refer to sections 117 and 119, while leaving the declaration and legal advice where they belong. For self-managed Ontario corporations, pricing is $49 per month for up to 25 units, or $99 per month for up to 100 units. The 30-day full-product pilot does not require a card, and if the corporation stops paying, its record remains readable and exportable.

Whether you use software or a disciplined shared folder, assign one director to check the file after each significant step. Keep the original evidence, record delivery, and write decisions while they are fresh. That is how a volunteer board keeps the record ready before anyone asks for it. This guide is general information, not legal advice; the corporation’s declaration and counsel govern.
