Here in Canada the air carriers are pretty

I can receive several ADS-B returns on a
single flight.

Hi George - the Dash-8's running Ottawa-Montreal over Gatineau and MSC aren't ADS-B equipped; neither are the Ontario provincial aeromedical evac helos that buzz through our MFA area. We see their transponders. Only the 3pm flights from Europe come in showing ADS-B. I expect we'll see more as 2020 approaches since most of the Dash-8's will also be going into NY and Boston.

We also see a lot of GA traffic over the Ottawa River...
