In Brief

  • This memorandum has been revised to provide more precise policy direction to commercial air carriers. This update clarifies who is required to provide Advance Passenger Information/ Passenger Name Record (API/PNR) data to the Canada Border Services Agency (CBSA), clarifies exceptional circumstances where API/PNR data may not be required, clarifies the definition of a crew member, and reflects the implementation of the CBSA’s Air Carrier Support Centre (ACSC). In addition, the embedded links have been updated as necessary.

This memorandum outlines the Canada Border Services Agency’s (CBSA) requirements and administrative policies regarding the provision of prescribed Advance Passenger Information (API) and Passenger Name Record (PNR) information with respect to persons being transported to Canada by commercial air carriers.


Customs Act, section 107(1)

Immigration and Refugee Protection Act, section 148(1(d)

Guidelines and General Information


1.   Under Canadian law, all commercial air carriers are required to provide the CBSA with prescribed information relating to all persons travelling to Canada aboard a commercial air carrier prior to, and at, the time of departure for Canada from a foreign point of origin. This information will be used by the CBSA to perform a risk assessment of passengers and crew while they are en route to Canada.  Additionally, the information will be used by the CBSA’s Interactive API (IAPI) process to validate, prior to departure, that all incoming air travellers hold a valid prescribed document to enter Canada or are exempt from that requirement, and that they are not considered to be prescribed persons. Failure to provide the prescribed information within the prescribed time and in the prescribed manner may result in the assessment of a monetary penalty.

2.   Subsection 107(1) of the Customs Act gives the Minister of Public Safety and Emergency Preparedness the authority to require certain persons to provide information to the CBSA. This authority is delegated to specified officials of the CBSA. The information to be provided and the conditions relating to the provision are set out in the Passenger Information (Customs) Regulations (PICR).

3.   An officer of the CBSA also has the authority to require the provision of the prescribed information under paragraph 148(1)(d) of the Immigration and Refugee Protection Act (IRPA). Section 269 of the Immigration and Refugee Protection Regulations (IRPR) sets out the persons who are required to provide the information, the information to be provided and the conditions for the provision of the information.

Accountability for Provision

4.   The CBSA requires all commercial air carriers to provide the prescribed information under subsection 107(1) of the Customs Act, as described in the PICR, and the prescribed information under IRPA paragraph 148(1)(d), as described in section 269 of the IRPR. As the prescribed information is the same under both Acts, one transmission of the prescribed information satisfies both obligations. The CBSA currently only collects API and PNR in the air mode. Therefore, the CBSA does not require commercial carriers in other travel modes (e.g., land, rail, or marine) to provide the prescribed information.

5.   In accordance with established best practices set out in the World Customs Organization’s Guidelines on Advance Passenger Information and the International Civil Aviation Organization’s Guidelines on Passenger Name Record Data, the CBSA holds the operating carrier of each flight responsible for the provision of all the prescribed information.

6.   The CBSA expects the operating carrier to work with relevant industry partners to ensure that all of the prescribed information is provided within the prescribed timeframes and in the prescribed manner.

Commercial Carrier

7. The terms “commercial carrier” and “commercial transporter” are defined in the PICR and the IRPR, respectively. As the definitions are functionally identical, the term “carrier” is used throughout this document in place of both terms.

8. A commercial carrier is an operator of a commercial aircraft. A commercial aircraft is an aircraft, regardless of size, which is used in the commercial transportation of persons or goods, where the persons or goods are conveyed:

9. Examples of commercial carriers include operators of a scheduled air service, scheduled and unscheduled charters, air taxi and air commuter operations, and air cargo flights.

10. For greater certainty, the CBSA requires all commercial carriers, including regional and local trans-border operators, to provide the prescribed information in the prescribed time and manner. This requirement applies regardless of the number of persons on board or the frequency of a commercial carrier’s operations. Commercial carriers are expected to provide the prescribed information for flights even if no commercial passengers or goods are on board (e.g., “ferry flights”, which include both service and repositioning flights).

11.  Operators of aircraft which do not fall within the above definition of “commercial aircraft” are not currently required to provide the prescribed information. Examples of non-commercial aircraft include those used for personal transportation or corporate/business aircraft, where there was no exchange of money for transportation. General Aviation is addressed in greater detail in Departmental Memorandum D-2-5-12, Telephone Reporting for General Aviation and Marine Pleasure Craft.

12. For carriers who operate both private and commercial flights, it is the specific circumstances of the flight, not the ownership of the aircraft, which determines if there is an obligation to provide the prescribed information to the CBSA. For the purposes of the API/PNR program, in these circumstances, a flight is considered “commercial” if payment has been exchanged for transportation.

13. A state directly operating a flight (e.g., a military flight) is not required to provide the prescribed information. However, where a state has paid for a commercial charter flight, the commercial charter carrier is required to provide the information. Commercial charter carriers should work with their state clients to ensure that the prescribed information is provided to the CBSA.

14. For greater clarity, in situations where the military is directly involved in the operation of a flight, e.g., a civilian crew operating a military aircraft to Canada with a military call sign, the CBSA would still consider it to be a military flight and there would be no requirement to provide the prescribed information to the CBSA, unless requested to do so by the CBSA under exceptional circumstances.

15. Commercial carriers transporting foreign nationals for the purpose of transiting through Canada are required to provide the prescribed information, including carriers who are participants of the Transit Without Visa (TWOV) and China Transit Program (CTP).

Exceptional Circumstances/Occurrences

16. In certain situations, the CBSA may not require the provision of API/PNR. These situations include:

The CBSA will not assess any administrative monetary penalties regarding the non-provision of API/PNR for such flights; however, it is required that an occurrence report is filed.

17. To avoid undue delays for flights undertaken for the sole purpose of emergency assistance, the CBSA requires that the carrier only provide the prescribed information in their possession prior to departure. Emergency assistance flights include:

18. In the case of emergency assistance flights, should all the prescribed information not be available at the prescribed times, the commercial carrier should report the occurrence and provide the missing information as soon as it is available. If these conditions are met, the CBSA will not assess any administrative monetary penalties for the late provision of API/PNR for these flights.

Prescribed Information

19. The law requires carriers to collect and provide specific prescribed information, as described in paragraphs 5(a)-(d) of the PICR and in paragraphs 269(1)(a)-(d) of the IRPR. The prescribed information, commonly referred to as API, to be provided about each person on board or expected to be on board the conveyance includes the following:

Further guidance regarding the API elements that are currently processed by the CBSA’s program is published in the CBSA’s Carrier Messaging Requirements (CMR) document which is provided to carriers upon registering with the program.

20. Additionally, pursuant to paragraph 5(e) of the PICR and paragraph 269(1)(e)of the IRPR, the law requires  a commercial carrier to provide any information collected about each person on board or expected to be on board a Canada-bound flight that is in its departure control and reservation systems or that of its agent. This information is commonly called PNR data and may include information aggregated from various sources (e.g., global distribution systems, airline reservation systems, and departure control systems).

21. Carriers are only required to provide the PNR elements they have collected for their business purposes that are included in the Appendix. Further guidance regarding the PNR elements that are currently processed by the CBSA’s program is published in the CMR document.

22. The prescribed information must be provided about every person whom a carrier expects to carry and/or is carrying to Canada. This includes fare-paying passengers, all crew whether on-duty or off-duty (e.g., dead-heading or relief pilots), and any other person who is on board or expected to be on board the aircraft when it departs for Canada.

23. Pursuant to paragraph 5(f) of the PICR and paragraph 269(1)(f) of the IRPR, commercial carriers are also required to provide prescribed information detailing the commercial carrier’s flight information. It is critically important that this prescribed contextual information is correct. Inaccuracies in flight number, arrival times, or ports of departure / arrival can cause the information to be processed incorrectly by the CBSA’s systems. The CBSA expects carriers to update or correct this information without delay if they become aware that it is incomplete or inaccurate, as per Section 8 of the PICR and subsection 269(6) of the IRPR. The CBSA does not expect carriers to update scheduled departure times.

Additional Traveller Information

24. Certain secondary document information may be required by the CBSA in order to determine if a traveller is exempt from electronic Travel Authorization (eTA) or visa requirements. As this information allows the CBSA to provide carriers with IAPI board/no-board messages that more accurately reflect the circumstances of a traveller, the CBSA recommends that carrier systems include a mechanism that allows them to accept and process more than one document for each traveller. For example, carriers should be able to provide Canadian Permanent Resident card information to the CBSA as a secondary document, as required.

25. Carriers that are unable to provide secondary document information in the manner requested may contact the CBSA’s Air Carrier Support Centre (ACSC) for assistance in determining the traveller’s board/no-board eligibility.


26. Carriers are required to provide the prescribed API information to the CBSA at the following intervals:

27. Carriers are required to provide the prescribed PNR information at the time of departure of the flight from the last place persons boarded the conveyance before arriving in Canada. Only one submission of PNR information is required. The CBSA discourages carriers from providing the prescribed PNR information before the time of departure due to the risk of last minute changes which may result in inaccuracy of the information provided.

28. Carriers are required to provide a “close-out” message to the CBSA no later than 30 minutes after the time of departure to identify the unique passenger reference numbers of the passengers who are actually on board the flight bound for Canada.

Note: "Time of departure" is defined as the time of take-off from the last point of embarkation of persons before the conveyance arrives in Canada.

29. For multi-leg/progressive flights, the CBSA recognizes that commercial air carriers may provide API for all Canada-bound travellers expected to be on board the aircraft at their point of check-in. In these cases, the flight information must include the last foreign airport before arrival in Canada and the first airport of disembarkation in Canada, and must match the departure and arrival ports provided for all API and PNR submissions for the same flight.

Message Format and Transmission

30. Carriers and their industry partners can establish a direct connection with the CBSA’s data acquisition system. Please note the CBSA collects an initial set-up and ongoing maintenance cost-recovery fee for all direct connections.

31. Alternatively, carriers and their industry partners may choose to use the CBSA’s secure web portal, the Internet API Gateway (IAG). The IAG allows the provision of the prescribed information through a file upload or by using Interactive Data Entry (IDE) functionality.

32. The CBSA will also accept submissions of prescribed API data via e-mail as long as it meets the CBSA’s technical parameters for provision.

33. Technical parameters for provision of the prescribed information through direct connection, the IAG or via e-mail are described in the CMR. The CMR is provided on request by the CBSA’s Carrier Account Support Team (CAST).

34. The CMR also details the CBSA’s requirements for message content and formatting. The CBSA supports the industry-standard UN/EDIFACT (PAXLST), PNRGOV EDIFACT and CUSRES message formats, as well as CBSA-specific ones including the CBSA XML and the Comma-Separated Variable (CSV) formats. 35. The CBSA does not accept non-electronic transfers (e.g., faxes) of the prescribed information.

36. Carriers and their industry partners may make arrangements with a service provider to provide the information on their behalf. The CBSA maintains a list of service providers certified with the Agency for API and/or PNR data transmission, which is available upon request. The CBSA will also certify any new service provider identified and authorized by the carrier.

Interactive API (IAPI) Process - Board/No-board Message

37. While the CBSA requires that API data be provided for all travellers on board or expected to be on board a Canada-bound flight, only those travellers identified as passengers are subject to the IAPI board/no-board process.

38. Upon receipt of API data for each passenger, CBSA systems will run automatic queries to determine if the passenger requires and possesses a document prescribed under IRPA or if they are exempt from that requirement. Based on this initial validation process, the CBSA will provide commercial carriers with an electronic board/no-board message.

39. The CBSA is providing information to the commercial carrier, who is ultimately responsible for making the determination on whether or not to board the passenger.

40. Crew members who are assigned to active duty on an aircraft are exempt from the board/no-board process. Dead-head crew, regardless of whether they are carried by their carrier of employment, are also exempt from the board/no-board process provided that they are identified as crew members in the message submission.

41. However, dead-head crew identified as passengers in the submission, as well as mechanics, cargo handlers/loadmasters, and in-flight security officers are processed as passengers and are not exempt from the board/no-board process described in paragraph 34.

Note: While board/No-board messages will not be issued to any travellers identified as “crew”, it is imperative that the carrier ensure that all travellers on board a flight to Canada hold a prescribed document to enter Canada or are exempt from that requirement in order to avoid any potential administrative fees.

Note: Specific crew-related exemptions to the eTA and visa document requirements are detailed in paragraphs 7.1(3)(d) and 190(3)(a) of the IRPR. The process for submitting the required data in these circumstances is detailed in the CMR and the IAPI Standard Operating Procedures for Commercial Air Carriers and Service Providers.

42. It is imperative that the CBSA have complete and accurate API information regarding travellers, both passengers and crew, as that information may impact the processing of that traveller by both the CBSA and the commercial carrier. Technical specifications and timeframes for updating information are outlined in the CMR.

Unsolicited Board/No-Board Message

43. On occasion, based upon a further review of a passenger’s information, the CBSA may provide commercial carriers with a subsequent, manual “unsolicited” message to override a previous board/no-board message.


44. Although a passenger may obtain an automated board message during the check-in process, the CBSA conducts further queries to determine if the passenger has an enforced removal order and/or if the passenger is the subject of a declaration under the Minister of Immigration, Refugees and Citizenship Canada’s Negative Discretion Authority (NDA) per section 22.1 of the IRPA.

(a)  A traveller who is the subject of an enforced removal order may require an authorization to return to Canada (ARC) in order to be admissible to Canada. For more information on removal orders, please see:

(b)  Negative Discretion refers to a foreign national who may not become a temporary resident in Canada as the Minister of IRCC is of the opinion that, due to public policy considerations, the individual should not be granted entry. The Ministerial authority is exercised via a declaration under the IRPA [subsection 22.1] for a period not to exceed 36 months. For more information on the NDA, please see:

45. Transporters have an obligation not to carry improperly documented or prescribed persons to Canada. Consequently, in certain instances, the payment of removal costs may be required. Further information may be found in the CBSA’s Guide for Transporters.

46. In general, an unsolicited no-board message may be sent to the commercial air carrier no later than 30 minutes prior to the flight’s scheduled time of departure to Canada.

47. In exceptional circumstances as determined by the CBSA (such as potential threats to public safety), unsolicited no-board messages may be issued at any time prior to departure.

48. Commercial air carriers may also choose to send an electronic acknowledgement to the unsolicited message upon receipt, if their system functionality permits. The submission of an unsolicited acknowledgement message is optional.

49. In certain circumstances, carriers will be required to provide the CBSA with updates to the status of a flight or changes related to a passenger’s reservation. These circumstances include:

(a)  instances where a Canada-bound flight has been cancelled but the carrier has previously provided the CBSA with information for a specific flight;

(b)  instances where one or more, but not all, of the passengers within a reservation has cancelled their itinerary to Canada; and,

(c)  instances where an entire reservation is cancelled.

Note: Commercial carriers should only provide these messages to the CBSA in the circumstances outlined above. If a carrier intends to communicate updated reservation details for a traveller (for example, an upgraded seat), cancelled reservation messages should not be submitted. The carrier may simply provide the CBSA with an updated PNR submission for that traveller.

Note: If a carrier has provided the CBSA with notification of a cancelled flight, cancelled reservation or cancellation of some passengers within a reservation and the flight and/or passenger reservation is reinstated, a full data submission of API and PNR (if PNR is collected) must be provided to the CBSA. Specific technical requirements for this process are detailed in the CMR.

System Outages and Changes

50. Operating carriers, or their industry partners, who are planning system changes that might affect their information processing or transmission systems, are expected to notify the CBSA at least six months before the changes are implemented. The CBSA will work with the carrier and their partners to ensure that there is no interruption in the provision of the prescribed information. System changes do not relieve the carrier of the obligation to provide the prescribed information.

51. Operating carriers are strongly encouraged to have a secondary method of transmission for the provision of the prescribed information in the case of a primary transmission outage. A system outage experienced by the carrier, the CBSA or otherwise does not relieve the carrier of their obligation to provide the prescribed information. The CBSA’s System Outage procedures are contained in the Standard Operating Procedures for Commercial Air Carriers and Service Providers document which is available upon request.

52. The CBSA also expects operating carriers to provide corrected information where there is a change to contextual information (e.g., time of arrival or destination) due to a system outage.

New Carriers

53. Operating carriers who intend to commence service to Canada will need to:

Notice to Travellers

54. The CBSA encourages carriers to inform their clients and personnel about the provision of prescribed information to the CBSA and about the CBSA’s programs. Legislation in place in other jurisdictions may require carriers to provide notice to travellers when the carrier provides information to the CBSA. The CBSA recommends that a notice to travellers contains the following:

The CBSAis authorized to collect advance information under subsection 107(1) of the Customs Act and paragraph 148(1)(d) of the IRPA. The CBSA uses the prescribed information to identify persons who may pose a threat to Canada's safety or security. These persons may be subject to investigation, and may undergo closer questioning or examination upon arrival in Canada. The CBSA also uses the prescribed information to validate, prior to departure, that all incoming air travellers hold a prescribed document to enter Canada or are exempt from that requirement. Persons who do not meet the documentary requirements for entry to Canada may be refused boarding. All travellers to Canada may request a copy of the prescribed information provided about them by making a request in writing to the CBSA. Any traveller who believes that the prescribed information provided about them was incorrect may make a request in writing to the CBSA to have the information corrected. Any traveller may complain in writing to the CBSA if they believe that the CBSA has unfairly refused to provide access to the prescribed information provided about them, has not corrected the prescribed information provided about them, or has otherwise incorrectly handled the prescribed information provided about them. Travellers can obtain more information by consulting the Advance Passenger Information/Passenger Name Record (API/PNR) program website.

55. The CBSA recommends that any travel notice be incorporated into websites or other documentation in a manner that would ensure that travellers researching or making reservations for flights to Canada are aware of the CBSA’s API/PNR program, including the IAPI process.

Reporting for CBSA Inspection

56. The requirement to provide the prescribed information does not relieve carriers of their presentation and reporting obligations upon arrival in Canada, as per the Presentation of Persons Regulations. Procedures for access to airports may be found in Departmental Memorandum D2-5-1, Charter Access to Airports.

Penalty Information

57. Carriers who fail to comply with the requirement to provide the prescribed information in the prescribed manner and in the prescribed timeframes are subject to administrative monetary penalties under the Customs Act. The penalty is assessed on a per-flight basis.

58. Non-compliance occurs when a commercial carrier fails to provide information as stipulated in the PICR, on persons (passengers and crew) on board a conveyance within the prescribed timeframes. Where the CBSA determines that the carrier made all efforts to provide the prescribed information, a zero-dollar penalty may be assessed.

Note: A carrier may also be subject to administrative monetary penalties for failing to provide Flight Update Notification messages or close-out messages.

59. The CBSA considers that the prescribed information has been provided if the information is:

60. Memorandum D22-1-1, Administrative Monetary Penalty System describes how the CBSA enforces compliance with the Customs Act and related regulations. The details of the administrative monetary penalties related to the provision of the prescribed information are published in the CBSA’s Master Penalty Document.

61. It is recommended that commercial carriers monitor all messages from the CBSA. Failure to receive an acknowledgment or flight summary message, a board/no-board message, or the receipt of an error message is indicative of a problem with the data transmission or the quality of the data.

62. The penalties described within this memorandum are separate from the administration fees which may be levied on commercial carriers related to the carriage of certain categories of inadmissible foreign nationals to Canada.  Administration fees are based on the IRPA and the IRPR and are described in greater detail in the CBSA’s Guide for Transporters.

Contact Information

63. The CBSA’s Carrier Account Support Team (CAST) is the primary point of contact for both technical inquiries and program-specific inquiries from carriers. They provide support through the CBSA’s API/PNR Program Support (APPS) line.


E-mail: or

Please note: E-mail inquiries are responded to between 08:00 and 16:00 ET on weekdays (except holidays).

64. The CBSA’s Air Carrier Support Centre (ACSC) is the primary point of contact for carriers regarding eTA, visa and other immigration document inquiries, following the receipt of a board or no-board message.


Note: The ACSC and APPS lines do not offer services to individual travellers. Travellers should visit the IRCC website, nearest mission or Visa Application Centre, should they require facilitation or have inquiries about the status of their immigration documentation or questions about the eTA.
