Cost would be $600, assuming you don't have Diamond status with Aeroplan. All taxes paid would be refunded, but the booking fee is not refunded.

It's possible that the fees would be refunded (or even reduced), and it doesn't hurt to ask, but I think they generally only do that in the event of death of a passenger. You may need to write in separately, as I don't think a phone agent would have the authority to reduce/waive fees.
