Any sort of activity every 18 months is required to keep your points active. This is 6 months longer than before. One way to avoid this is by holding an Aeroplan credit card. In July 2020, Aeroplan introduced a new policy. Within six months of a member's account becoming inactive, when they fly Air Canada or get an Aeroplan credit card, Aeroplan will then reactivate all of those recently-expired miles. They've also introduced some special policies related to members impacted by COVID-19.
