The instructions on how to do this are: 

* If you need to check flights and schedules, log on to
  http://www.aircanada.ca/home.html 

* Contact the Employee Call Center at 1 800 413-1113 or
  alternatively general res 1 888 247-2262 if calling
  ourside the Employee Call Center normal hours 

* Advise the agent you are a severed employee with a
  buyout package, the agent will register/list you for
  the flights without your employee file information as
  you are no longer an employee 

* Note that Air Canada flight numbers 3xxx are CP
  flights/equipment and 5xx series are AC
  flights/equipment - former CTS employees' priority is
  C3Y10 on CP equipment and C5Y10 on AC/Rgnl equipment 

* Once the agent gives you a record locator please
  advise Air Canada Employee and Industry Travel
  Services (formerly Employee Travel Services)
  604-270-5667 and they will append the authority on
  your record locator 

* as we are no longer on Air Canada payroll, ETS will
  require your payment before the tickets can be made
  out 

* tell ETS that you are a severed employee with a buyout
  package and they will look up your file, which is kept
  with them, for your dependants and remaining ticket
  allotment 

* alternatively, if you are not in a hurry or you can
  not get through via the phone, ETS can be reached at
  PassPolicy@cdnair.ca (email that I used) or
  CDNpasspolicy@cdnair.ca (new email from latest address
  book) or Elaine_Tremblay@cdnair.ca (who appears to be
  the person who returns emails to PassPolicy@cdnair.ca) 

* Once this is done, you may pick the tickets up at the
  ETS office located on the 3rd floor of the Ops Centre
  building, closest to the East entrance where the crew
  bus picks up passengers 

* Alternatively, the tickets I believe can be sent to
  the airport to be picked up but only during the
  employee pick up times 9 - 11am and 7 - 9:30pm 

* If you change your itinerary with respect to flight
  times and dates, the same tickets can be used 

* If you say change destinations within the same zone
  (ie. YVR-LAX-YVR to YVR-SFO-YVR), you must bring the
  tickets back to the airport between 9 - 11am and
  7 - 9:30pm for them to modify and exchange 

* If you say change destinations to a different zone
  (ie. YVR-LAX-YVR to YVR-NRT-YVR), you must bring the
  tickets back to the airport between 9 - 11am and
  7 - 9:30pm to have the tickets refunded and returned
  to your allotment and start this entire process to
  list and request new set of tickets
