In a press release issued by Nav Canada on August 2, Canada’s air navigation service provider announced that, in cooperation with state regulator Transport Canada, they are delaying the implementation dates of the ADS-B mandate that were previously announced earlier this year due to supply chain concerns.
The ADS-B technology required for use in Canada includes a transponder emitting 1090 MHz extended squitter and antenna diversity, meaning upwards and downwards pointing antennae.
To operate in Canadian Class A airspace (FL 180 to FL 600), appropriate equipage will be required by August 10, 2023 (previously scheduled for February 23, 2023). To operate in Canadian Class B airspace (12,500 ft to FL 180), appropriate equipage will be required by May 16, 2024 (also previously scheduled for February 23, 2023).
As for Canadian Classes C, D and E airspace, the announcement indicated that there is no change, stating as in the earlier press release that it will be no earlier than 2026.
