Just out of curiosity: is the tracking system based on FLARM data or do
they all carry an additional tracker? I am just baffled by the resolution
and refresh rate of the tracking site compared to what I have seen from
US
contests.

You don't need a FLARM to be tracked; a simple OGN tracker can be made for about $50US so the cost of playing is less than FLARM (though without the benefits of anti-collision warnings).

You can see the ranges the OGN receivers get in the Ottawa area (3 clubs have receivers and I'm about to put one on my soon-to-be new roof in the west end to cover off the western flying area). We also bring a portable to Lake Placid wave camp - you can see the returns from last year:

You can see the Ottawa and Montreal Terminal areas; only a few gliders have transponders and can easily transit the Class C (in the upper right, select "Options" and select "Airspace" to see our problem - also, we cannot cross the border to those nice clouds near Ogdensburg NY). Pretty amazing for simple (cheap) receivers and a FLARM transmit signal of one (Portable) or two (CORE) hundredths of a watt!
