The normal process is this:
- You file a report at the airport your luggage is delayed.
- You buy everything you need in the interim and keep the receipts meticulously and file them with the airline ASAP. ( Air Canada )
- Review airline policies whether any additional steps are required. AC on the link mentions something at three days, for example.
- After 21 days or when the airline admits the bag is lost, you initiate a process for compensation of the contents.
- Within two years you sue the airline if they don't pay.
For 2+3 together the responsibility of the airline is 1,288 Special Drawing Rights (which is approximately $2,400 CAD) per passenger.

There's also the non-trivial question of who is responsible in the first place but this should've been made clear at the airport when you reported. If not, that'll be a bear to untangle.
- What were the flight numbers you've flown?
- What is the first three digits of the reservation number? It should be 13 or 14 digits and most likely starts with 014 or 020 or maybe 016.
