Did the bags turn up? I'm still awaiting a lost bag from the Air Canada YYZ-EDI flight on 28th June. There were quite a few passengers whose luggage didn't arrive on the conveyor. I have been to the temporary storage unit run by Swissport at Edinburgh Airport where there is easily over 100 Air Canada bags. Many of them marked Signature Class Priority (like mine!). The staff in the facility tell me the bag hasn't left YYZ.
The AC contact form was a bit of a nightmare to complete - insisting on attachments before it would accept submission. Got round it by sending a phone photo of the AC section in the baggage facility. Couldn't think what else to send.
I'd much rather have my belongings than any compensation or insurance money.
