I’m just reading the June 2017 issue of AOPA Pilot (USA) magazine. It lists the requirements for ADS-B.
Under Canada it says:
“Canada has no mandate, but operators who voluntarily equip with 109ES (particularly in the Hudson Bay and nearby Oceanic Airspace) can receive a high level of service. However Nav Canada is a lead partner in Aireon, the joint air traffic surveillance venture, installing ADS-B equipment on low Earth orbit satellites.”
What a pity Airservices was not similarly minded here. The Aireon ( iridium based) is going to be equipped on the next satellites that are going into orbit and of course gives coverage everywhere.
It is so sad that this huge impost was put in the industry in Australia, doing untold damage. Whereas a country like Canada, which is very similar to Australia in physical size and radar coverage, can be so sensible.
