Live forecasts update automatically; written guidance last reviewed 16 June 2026 by the True North Brief Weather Desk. Data from Environment and Climate Change Canada and other national met services via Open-Meteo.
Environment Canada’s network of 31 Doppler radars across Ontario provides real-time precipitation data at 10-minute intervals, covering the province from Windsor to Thunder Bay. The live radar above shows current rain, snow, and mixed precipitation intensity, updated every six minutes for the most accurate picture of active weather.
What does the Ontario radar show right now?
The live radar above displays reflectivity values from -28 to +68 dBZ, with green indicating light rain (0.1–2.5 mm/hr) and red-to-purple signalling heavy precipitation (50+ mm/hr). For southern Ontario, the King City and Exeter radars offer the best coverage of the Greater Toronto Area and the 401 corridor. Northern Ontario relies on the Timmins and Dryden radars, which capture lake-effect snow bands and summer thunderstorms. Use the 24-hour loop to track storm movement and the weather warning page for active alerts.
How to interpret the radar for your location
Each radar site scans up to 250 km in radius, but beam blockage from terrain can reduce accuracy in the Muskoka region and along the Niagara Escarpment. For the most reliable data, cross-reference the live radar with the Toronto weather page or your local forecast. The ontario weather radar 24 hours loop is especially useful for tracking the approach of cold fronts or lake-effect squalls off Lake Huron and Georgian Bay.
How do I view the 24-hour future radar for Ontario?
The live radar above includes a time-lapse control. Click the play button to loop the past 24 hours of precipitation data. This is the best tool for the 24 hour future radar trend, showing whether a storm is intensifying or weakening as it moves east.
Is the Toronto weather radar live different from the provincial radar?
No—the toronto weather radar live feed is the same King City radar data used for the provincial map. The live radar above defaults to a southern Ontario view, but you can zoom in on the GTA for higher resolution around Toronto, Mississauga, and Hamilton.
Can I see weather radar Ontario satellite imagery together?
Yes. The weather radar ontario satellite view is available by toggling the overlay option on the live radar. This combines visible/infrared satellite cloud cover with the precipitation radar, giving you a complete picture of both cloud tops and ground-level rain or snow.
