Airlines often waive fees for rebookings due to jury duty.
The OP is not on jury duty.
Death would of course mean no future travel is possible by the deceased.
AC has a lengthy list of eligibility for compassionate waivers to fees/non-refundability in matters of such an ultimate misfortune.
There is no death, related or otherwise here.
Questions about the ticket in question should be referred to the Aeroplan account-holders appropriate line and not the SE desk, no matter how much the OP wishes to influence the outcome.
