Short answer: US agencies dispute only in ARC Memo Manager, with the amount, the reason and the proof. A departure or arrival change of 3 hours or more allows a refund, and a change under 3 hours does not. An unused ticket is valid for one year from the original issue date, or as the fare rule says.
The rules below are Air Canada's own, from its agency pages, each with its source and the day we checked it. For the date math on a memo or a credit, open Air Canada in the airline policy finder.
