"The Canadian weather radar network consists of 31 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each has a range of 256 km (159 mi) in radius around the site to detect reflectivity, and a range of 128 km (80 mi) for detecting velocity patterns (Doppler effect)." -- https://en.wikipedia.org/wiki/Canadian_weather_radar_network This particular radar covers Eastern Ontario and Western Quebec. It is impossible to visit the premises of the radar, but the radar is visible from the gate. 5-10 minutes will suffice to visit.
