Small claims court.

Claims:

1) Damages = _. (not just the dry cleaning bill). Any impact to your bottom line, your business? Seek them
2) An order for pre-judgment and post-judgment interest pursuant to sections 128 and 129 of the Courts of Justice Act;
3) An Order that the Defendant pay costs to the Plaintiff on a substantial indemnity basis;
4) Such further and other relied as counsel may advise and this Honourable Court permit; (if you are retaining counsel, which is not usual in small claims court)

These are just claims (eg asks) and it's unlikely you will get costs, but you might as well ask.

You will settle but that's the only way to get AC's attention.

This will cost you $95 to file this if you are an infrequent claimant and if you choose to use a process server another $40.
