Air Canada is currently offering a lot of flexibility on all new and existing bookings made through June 30th, 2020 for travel between March 1, 2020 and June 30, 2021 if you booked directly. You can cancel for any reason and either get a travel voucher with no expiry or you can turn your cancelled tickets into Aeroplan miles with an additional 65% bonus, that works out to cost 1.3¢ per mile. Aeroplan recently sold miles for as low as 1¢ per mile, so not as good as that previous offer.
