I think more importantly (emphasis is mine):
If your miles do expire, don't worry. Within six months of your account becoming inactive, if you fly on an eligible Air Canada ticket or get any Aeroplan credit card, we'll reactivate all of your recently expired miles.
We also understand that you may have been forced to adjust your travel plans due to COVID-19, so we're taking additional action. If you purchased a trip with Air Canada prior to July 20, 2020, with travel commencing anytime since January 2020 and had to cancel your travel plans, we'll be happy to reinstate all of your Aeroplan Miles which have expired since the beginning of this year. You'll just need to have your Air Canada booking reference on hand.
To take advantage of any of these options, simply call the Aeroplan Contact Centre.
