Are you curious about the Air Canada Refund Policy? Assuming you book a ticket through one of the aircraft's reserving channels, you will actually want to drop it without penalty. If the booking is made over 7 days preceding the planned flight takeoff and is dropped in 24 hours of purchase, you will get a full discount. Please note that such Air Canada discount terms don't make a difference to gatherings of ten or more individuals.
