I hope OP writes back with that he receives. My guess is a 25% off coupon and any documented reasonable expense receipts reimbursed.
If OP had them issue a hotel voucher+meals at the airport, that would go a bit further helping customer service "remember" it was an AC issue (rather than passenger showing up late at counter etc).
//OP also earned extra status and redemption miles as a result of the YVR connection. Plus an extra gourmet meal. Isn't that compensation enough
