1) Couple arrived with no bags.
2) Couple put in "lost bag" notice with Air Canada.
3) Air Canada didn't find the bag within 30 days and paid compensation (per law).
4) Couple deposited compensation.
5) The bag (along with others) in a big pile was donated to charity.
The status of the bag is iffy once compensation is paid.
IANAL, but I think its like the cases where a car is stole, insurance pays out, and then the car is recovered. You don't own that car in that case.
