Due to supply-chain limitations experienced in the context of the global pandemic, some customers have identified that they may not be able to meet the equipage requirements in time for the mandate effective date and, in some cases, they may require additional time to comply. To help this small number of customers bridge the gap, so long as system capacity permits, NAV CANADA will strive to accommodate aircraft unable to transmit ADS-B in accordance with the Canadian ADS-B mandate, in a similar fashion as accommodations are handled today for aircraft without functioning transponders in transponder mandatory airspace.
The three principles NAV CANADA will apply for ADS-B accommodation requests will be: safety, type of ATC separation service available in a given airspace and impacts to other airspace users.
Assessing ADS-B accommodation requests will be a manual process and will take time for each flight. NAV CANADA will need to assess alternative surveillance means for each flight and determine if all the affected air traffic control specialties will be able to adequately handle the procedural-separation needs of unequipped aircraft on requested routes and altitudes.
To provide enough time to perform each of these assessments, NAV CANADA will require ADS-B accommodation requests to be submitted at least three business days in advance. ADS-B accommodations for unequipped flights will generally be issued on a first-come first-served basis, although NAV CANADA will ensure that requests for unequipped priority flights (such as MEDEVAC, VIP, Rescue, etc) will be prioritized.
NAV CANADA will always try to communicate the capability to accommodate the route and/or altitude as soon as possible, and in no case will it be later than four hours prior to the expected time of departure. In cases where routes and/or altitudes are not conducive to accommodate unequipped aircraft, NAV CANADA may be able to propose alternative flight planning options for the pilot to consider. For cases where NAV CANADA has agreed to accommodate a flight that is unequipped, details of what to include in item 18 of the flight plan will be provided. In-flight accommodation requests will not be considered and, if traffic conditions or other operational circumstances change, NAV CANADA may need to rescind already agreed upon ADS-B accommodations.

Blanket accommodations may be made available to air operators with regularly scheduled flights. Air operators wishing to request a blanket accommodation agreement should contact firstname.lastname@example.org.
