Transport Canada Regulatory Initiatives - There are no new regulatory initiatives to report in this issue

Transport Canada Advisory Circular Advisory Circulars (AC) – Transport Canada has not issued any new ACs since the last CBAA Government & Regulatory Affairs Update. However, IPB 2024-04 - NVG Operations Considering 5G Interference and the Requirement for a Serviceable Radar Altimeter (RADALT) was issued which, in due course, will amend AC 603-001.

Internal Process Bulletin (IPB 2024-04) is associated to AC 603-001 that describes an acceptable means of demonstrating compliance with regulations and standards. The conditions within the IPB are accepted as meeting the intent of AC 603-001, Appendix A – Specific Requirements to meet Special Authorization Requirements for Night Vision Imaging Systems Operations – Additional Aircraft Equipment 2.0 (4)(1)(c). 

AC 603-001 defines acceptable conditions for NVG operations in Canada, which include a serviceable RADALT.  While this IPB was published to specifically address possible safety issues in helicopter operations, the IPB states that operators holding an Air Operator Certificate (AOC) or Private Operator Registration Document (PORD) may continue NVIS flights in Canada under VFR conditions in accordance with AC 603-001 under the conditions specified in the IPB.  

Note: IPBs are temporary document used by TC to develop and implement immediate changes until such a time as the source document can be formally amended.  It applies to TC staff and aviation stakeholders equally. AC 603-001 will be amended soon to reflect the contents of this IPB.

NAV CANADA updates

  • Nav Canada Aeronautical Study - Secondary Surveillance Radar (update) - In the last issue, we shared Nav Canada’s reminder (linked here) to operators of Aeronautical Studies undertaken to review Secondary Surveillance Radar (SSR) requirements at several locations (message linked here) as previously announced in March 2024.   On May 22nd, the Association participated with other industry stakeholders to an Nav Canada engagement session on May 22nd. The Association participated in the session and received clarification about the project (see presentation here). 

While the initial information about the NavCanada project seemed to be primarily related to the requirement to replace aging Secondary Surveillance infrastructure in the specified locations, Nav Canada’s ultimate ask relates to how stakeholder operations would be impacted if an existing SSR were to be decommissioned. 

Although Nav Canada had indicated that the target date for comments was May 29th, they have indicated that comments can be provided beyond that date. As such, member feedback is crucial for understanding the potential implications for Nav Canada to make informed decisions. Feedback can be sent directly to studies.etudes@navcanada.ca.  The Association would appreciate being copied to membersupport@cbaa.ca so that it may fully understand impacts on members, consolidate these with our own comments to continue advocating on your behalf. 

ICYMI – Foreign Entry Requirements

New US Rules for Entry of Dogs to the US - Members should be aware that the US Center of Disease Control (CDC) (linked here) has issued new regulations to control the entry of dogs into the United States from other countries. These rules apply to all dogs, including puppies, service animals, and dogs that left the United States and are returning. They also apply whether you are a U.S. citizen, legal U.S. resident, or foreign national. The CDC has advised that person who do not follow the CDC’s rules will see their dog refused entry into the United States. If entry is by air and the dog is denied entry, it will be sent back to the last country of departure at your expense. Country of departure is where the last trip originated—not where the dog was born or where it lives. In addition, the  US Government has reminded thatU.S. Department of Agriculture’s (USDA) and your U.S. destination’s regulations must also be complied with. Please be aware that dogs imported for commercial (resale or adoption) purposes haveadditional requirements from USDA

Argentina: Overflight Permits Now Required - Although CBAA members may have been advised already through other media, we are sharing that, effective 13 March 2024, all foreign aircraft are now need an overflight permit when transiting Argentinian airspace. There has been no change to landing permit requirements: private flights don’t need one, all other flights do (including tech stops). The Argentina Civil Aviation Authority has published AIP SUP 32/2024 with all the new requirements. A summary can be seen here.

Important Note:We are advised that the Argentinian Authority is quite specific about requirements. Don’t assume you have been granted a permit until you have specifically heard back from them.

Transport Canada Regulatory Initiatives

To ensure that the membership is aware of key regulatory initiatives at TC, their impacts, and how the Association is advocating on your behalf, here is the CBAA’s Summary and preliminary Analysis of the Transport Canada Regulatory Initiatives for the 2024-2026 period.  This summary is maintained as initiatives proceed. As well, the CBAA’s Summary and Preliminary Analysis document also includes other TC proposals issued for consultation where member input would be welcomed.

  • Proposed Amendment to the CARs - Personnel Licensing and Training - On Saturday 30 March 2024, Transport Canada published through the Canada Gazette a proposed amendment the CARs 400 series - Personnel Licensing and Training and some associated amendments to CAR 604 training requirements for a 30-day comment period that closed on 29 April 2024. Submitted comments may be seen in the Canada Gazette link.  An initial Association summary and analysis can also be seen here. Further information on the changes and comments received will be shared as it becomes available.

  • TC Notice of Proposed Amendments (NPA) - NPA 2024-001 – Update - In January 2024, we shared TC’s Notice of Proposed Amendment (NPA 2024-001) to amend the Canadian Aviation Regulations (CARs Part II) in relation to aircraft identification, registration, and operation of a leased aircraft by a non-registered owner. The Association did not comment on the NPA as our review of proposed changes concluded that they would not impact members. TC has advised that it received 245 submissions from various stakeholders mostly from the general aviation sector. A summary of these comments is shared in the enclosed What We Heard report.

  • NPA 2024-007 - Low Impact Amendments to Address ICAO Findings - TC has published NPA 2024-007 titled Low Impact Amendments to Address ICAO Findings. The proposed amendments seek to address areas of the Canadian civil aviation regulatory framework that are misaligned with the International Civil Aviation Organization’s standards.  These changes address issues concerning foreign medical examiners, carriage of documents on board the aircraft, the aircraft flight manual, ground and flight training programs, read back of safety information, air traffic flow management and pilot-in-command authority and responsibility.


The Association’s review of the proposal shows that this amendment is not expected to have a significant impact on business aviation operators. It is of note that some operators may need to adjust documents carried on-board aircraft and their audit checklists. Business aviation operators that also operate under CAR 703 or 704 may have to adjust their documentation in several areas which would align with CAR 604 requirements if not already in-place. Should you wish to provide comments to TC, you may do so in writing via the Comment Submission Form for NPAs or directly to TC at TC.CARConsultations-RACConsultations.TC@tc.gc.ca no later than June 11, 2024.

  • Approach Ban Initiative – Special Issue Aviation Safety Letter (ASL) - Over the past months we have shared several updates of TC’s work towards revising regulations related to the Approach Ban including the Association’s detailed comments on how best to address Graphic Area Forecast (GFA).  Through various discussions with the aviation community, TC has moved to address the matter wholistically. In this special issue (linked here) of the ASL, TC has summarized the various part of what is now called the Approach Ban Initiative and is being led by the Associate Director General of Civil Aviation. We look forward to sharing further information from TC and to contributing to this initiative.

  • Flight Duty Time and Fatigue Management Assessment Paper - Consultation Period Closing Soon - Transport Canada has published here a Preliminary Issue and Consultation Assessment (PICA) paper for consultation. The PICA has been prepared in recognition that, since the flight and duty time regulations have come into force, concerns have been raised by this Association and all segments of the aviation industry. Through this PICA, Transport Canada is advising that it wishes to work with industry to address concerns. The document represents the first step in the consultation process to gather information that will inform the next steps moving forward. TC will analyze the information that is received, and key themes and focus areas will be identified to inform the next steps, which could include focus groups, working groups, issues papers and so on.


Although the consultation period is closing soon (20 May 2024), please send comments or feedback to membersupport@cbaa.ca and the Association will ensure TC considers them in their analysis.

  • Proposed Vancouver International Airport Zoning Regulations (VIAZR) – The regulations were pre-published  in the Canada Gazette, Part I on 20 April 2024 for a 60-day consultation period ending June 19th. These regulations are being proposed to ensure the future viability and safe airport operations, minimize wildlife hazards and communication interference, and correct and clarify airport terminology.
