Updated timeline for ADS-B mandate in Canada

August 3, 2022  By Helicopters Staff

NAV Canada on August 2 confirmed, that due to supply chain impacts related to the COVID pandemic, the previously announced implementation dates for the Automatic Dependent Surveillance – Broadcast (ADS-B) Out Performance Mandate have been adjusted for Class A and B airspace.

In coordination with Transport Canada, NAV Canada explains new dates have been developed based in part on customer feedback regarding supply chain limitations and backlogs to acquire and install the appropriate transponder, as well as current equipage levels in each class of airspace.

As a result, the mandate will come into effect as follows: Class A Canadian airspace on August 10, 2023; Class B Canadian airspace on May 16, 2024; and Class C, D and E to occur no sooner than 2026 (to be determined pending further assessment).

In February 2022, NAV CANADA announced Canada’s plan to implement ADS-B Out mandate to enhance aircraft operations in domestic airspace – requiring aircraft operators flying in certain domestic airspace to meet ADS-B Out Performance Requirements.


“The valuable input we have received from our stakeholders and partners on the Canadian ADS-B mandate indicates that later dates for the mandate requirement are warranted as the industry continues to navigate the ongoing impacts to supply chains due to the pandemic,” said Jeff Dawson, Assistant Vice President, Operational Support. “We are taking these steps to ensure customers have adequate time to comply with mandate equipage requirements.”

“What we are seeing in terms of equipage is very encouraging – rates in Class A airspace are at 95 per cent, while those in Class B airspace are above the 88 per cent mark and growing steadily.”

To meet the ADS-B Out Performance Mandate, aircraft will be required to:

• Be equipped with an appropriate transponder with ADS-B out capabilities and performance with the applicable standard of Radio Technical Commission for Aeronautics (RTCA) DO-260B, “Minimum Operational Performance Standards”, or newer.

• Have antenna capability for broadcast toward space-based ADS-B receivers emitting 1090 MHz extended squitter. This requirement can be met either through antenna diversity (the use of a top and bottom antenna) or with a single antenna that is capable of transmitting both towards the ground and up towards satellites.
