Cranes and Structures

First and foremost, please let our team know what you’re planning to do as far in advance as possible. Contact us via email.

A Land Use Application must be submitted for any structure (building or crane) within 6 nautical miles of the airport or which will be more than 100 feet in height. NAV Canada’s website provides detailed information on submitting a Land Use Application. You can expect a NAV Canada Land Use Application to take at least six weeks to be processed.

Any person who plans to construct or modify a building, structure or object (like a crane) is required by regulation to notify Transport Canada via the submission of an Aeronautical Assessment Form for obstacle notice and assessment. In the submission, the person needs to clearly identify for Transport Canada, how they intend to mark and light the building, structure or object in accordance with the standards contained in Standard 621. Where the lands may be affected by AZR, Transport Canada will request a legal survey to demonstrate that the building, structure or object is clear of the AZR.

Please note that Transport Canada requires a minimum of 90 days to conduct a full review after confirmation of receipt of the completed Aeronautical Assessment Form. In some cases, it can be longer depending on the complexity.

For additional guidance on when to submit an AAF, please reference Transport Canada Advisory Circular (AC) 601-007 When to Submit an Aeronautical Assessment Form (AAF).
