King City weather radar station, Weather radar station in Ontario, Canada
King City weather radar station is a 16.45-hectare site at 360 m elevation in King City, Ontario, with a 27 m tower. Since 2021 it carries an S-band dual-polarization radar with an 8.5 m antenna, replacing the 2004 C-band unit. It is operated by Environment Canada as the primary research station of the Canadian weather radar network.
The station opened in 1984 as Canada's first facility using Doppler radar technology for weather observation. This technology enabled more precise measurements and transformed how meteorological data was collected across the country.
The station's data feed forecasts for the Greater Toronto Area and the Golden Horseshoe around the clock. Its radar is sensitive enough to register bird migration, especially when combined with other network stations. Researchers also use it to identify precipitation particle types and validate satellite data.
Visitors can view the facility from the outside, but access to the grounds is limited since it remains an active meteorological research site. The best viewing points nearby offer a look at the radar tower and structure from a safe distance.
The station's 2021 S-band radar has a peak power of 750 kW and an 8.5 m antenna, giving a reflectivity range of 300 km and a Doppler range of 240 km. Its data feed forecasts for the Greater Toronto Area and the Golden Horseshoe.
