  • Connection to international flight(s):
  • Carrier's IATA code
  • Flight number
  • Flight date
  • Origin and destination of the 24 hours connecting flight:
  • Air Canada’s 014 connecting ticket (if space permits in endorsement box). Other airline's ticket number is not an acceptable cross-reference without carrier's flight number, date, origin and destination of connecting flights.

Example: AC856 08FEB26 YYZLHR

  • Connection to an international cruise
    • CONX TO “cruise’s name”
    • Port's name
    • Date of sail
    • Length of cruise (by days)

Example: CONX TO PRINCESS MIA 08FEB26 7D

Note: Connecting to a cruise does not exempt the ATSC (CA), the AIF (SQ), or the AIFD (W1) as this is not a connection to air transportation.

  • Surface travel exists in the journey
    • Mode of transportation
    • Dates of travel
    • Origin and destination of surface travel (using “//” as symbol in between). This is required in order to connect any intra-Canada/transborder travel to the international travel

Example: GREYHOUND BUS TOUR 08FEB YYZ//DTW

Note: Connecting to any other mode of transportation does not exempt the ATSC (CA), AIF (SQ), or the AIFD (W1) as this is not a connection to air transportation.

Incorrect or Missing Endorsement

  • The travel agency that has issued all the tickets making up the continuous journey must maintain meticulous records which would serve as evidence that the journey was indeed continuous.
    • If evidence is not available or cannot be documented or retained at time of sale, any applicable taxes must be collected.
  • Travel agencies will be charged a service fee of  20% value of the memo (minimum$50.00 CAD/USD) plus applicable tax for a missing or incorrect cross-reference.
  • Air Canada will issue a debit memo for the value of the taxes to the agency.
  • It will be the travel agency’s responsibility to provide the required documentation to validate tax exemption if requested.
    • If the agency is unable to provide such information, they will be required to pay the debit memo.
    • Air Canada reserves the right to charge interest and penalties should the debit memo amount be substantial.
