A compliance letter does two jobs. It asks a unit owner to fix a problem, and it starts the paper trail your corporation will rely on if the problem does not get fixed. Most letters written by volunteer boards do the first job and fail the second. This guide covers what the letter must contain, gives you a full sample you can copy, and lists the mistakes that cost boards later.
Section 119 of the Condominium Act, 1998 requires every owner and occupier to comply with the Act, the declaration, the by-laws and the rules. Section 17(3) puts a matching duty on the corporation: the board must take reasonable steps to ensure compliance. A hallway conversation satisfies neither. A dated letter that cites the provision, describes the facts and sets a deadline satisfies both. If the dispute ever reaches mediation, arbitration or the Condominium Authority Tribunal, the first question will be what the corporation put in writing and when.
Check your draft against this list before it goes out:
One point trips up many new directors. Ontario condo corporations do not levy free-standing fines. A letter that threatens a “$100 fine” threatens something the board has no power to impose. What the corporation can recover is its actual costs, through the indemnification provisions in its declaration. Write the letter accordingly.
Replace the bracketed text with your own details. Keep the structure. It exists so that a stranger reading the file two years from now understands exactly what happened.

Re: Compliance with Rule [3.2] (Storage on balconies), Unit [12]
Dear [Owner name],
On [July 14, 2026], the board observed [a propane tank and construction materials stored on the balcony of Unit 12]. Rule [3.2] of the corporation’s rules provides that [“balconies shall not be used for the storage of goods or materials”].
Section 119 of the Condominium Act, 1998 requires all owners and occupiers to comply with the Act, the declaration, the by-laws and the rules of the corporation.
Please remove the stored items and restore the balcony to its permitted use by [July 28, 2026]. If compliance does not occur by that date, the board may take further steps available to it under the Act and the declaration, and costs the corporation incurs may be recoverable from you under the indemnification provisions of the declaration.
If you believe this letter was sent in error, or you need more time, contact [name] at [email] within 7 days.
Sincerely,
The Board of Directors, [Carleton Condominium Corporation No. 000]
Deliver the letter by a method you can document: email with a delivery record, registered mail, or hand delivery noted in writing with the date and the name of the person who delivered it. Then file the letter, the proof of delivery and any response together with the photos from the original observation. When the next board inherits the file, the whole story should be in one place. Three documents per incident is the minimum: the evidence, the letter, the proof of delivery.
This guide is general information, not legal advice. Confirm the specifics of your situation with a condo lawyer or the Condominium Authority of Ontario (CAO).
