Does anybody know the answer to the thread subject? Refund on seat selection fee if using eUpgrade? [non award ticket]

Edit:

It looks like it is not:

Advance standard seat selection charges are non refundable, except if:

• you are moved to a seat different than the one you selected due to an involuntary schedule or airport change (e.g. flight disruption, cancellation). If you are moved from your seat for one of these reasons, you may request a refundfor your seat charges.
• you decide not to travel on your selected itinerary and you paid for advance standard seat selection. The value of your advance standard seat selection charge will be retained and can be applied towards seat selection on a future Air Canada itinerary.
