Any pilot who decides to stay beyond 60 or come back is still a member of the bargaining unit represented by ACPA. For that reason ACPA had better be very, VERY careful how they treat these individuals. Their current strategy of punitive and discriminatory treatment will land them in DFR complaint territory in the blink of an eye along with more CHRT complaints.
ACPA and Air Canada are directly responsible for the hostile attitude many of our members have towards people in favour of 60+. ACPA chose an outdated, divisive position on a moral human rights issue that was inevitably doomed from the start. Despite obvious societal changes to mandatory retirement in general, the age 60 question for pilots around the globe and an actual ruling against them by the CHRT last august, discriminating against pilots older than 60 is not only still acceptable but official ACPA policy.
ACPA will never be credible in ensuring equal treatment of over 60 pilots.
