3. For high traffic density areas NavCanada is considering ground based antenna. The example he gave me was that if you have a ground station only system you will probably be ok in YVR class C, but not in YLW class C.
It seems silly not to do this for the high density airports.
Picking up 1090 ADS-B OUT traffic is so inexpensive that they would be foolish not to have a few receivers setup just in case they lose the datalink to the satellite provider.

Maybe broadcasting on 978, like the US? With Wx, Notams, etc.?
Doubtful. They seem pretty uninterested in helping the people working on weather broadcasting trials.
I have a test transmitter on 915 MHz setup that can broadcast weather to Stratux users but crowdsourcing a ground network is going to be a lot of work compared with Nav Canada setting up transmitters at existing sites. More information here.

They give the excuse that Canada is to large to affordably service but realistically you only need towers in areas were there is weather data to broadcast. Only broadcasting weather in areas where data exists really cuts down on the number of stations needed.
