Live forecasts update automatically; written guidance last reviewed 16 June 2026 by the Canada Perspective Weather Desk. Data from Environment and Climate Change Canada and other national met services via Open-Meteo.
Check the live radar above to see where precipitation is falling right now across your region, then use the detailed loops to judge whether rain or snow will reach your neighbourhood in the next hour.
What does the live radar show for my area?
The live radar above displays the most recent scan from Environment and Climate Change Canada’s network of weather radar stations. For example, the ontario weather radar 24 hours view reveals how bands of rain or snow have moved across Lake Ontario and the Greater Toronto Area through the day. Over the Atlantic provinces, the weather radar atlantic canada loop is especially useful for tracking the fast-moving systems that sweep in from the Gulf of St. Lawrence. If you are in eastern Newfoundland, the weather radar near st john’s nl site gives you a local window on arriving showers or fog.
How do I use the 24-hour radar loops?
The toronto weather radar 24 hour and ontario weather radar live loops are your best tools for seeing whether a line of thunderstorms is strengthening or weakening. For southern Ontario, compare the toronto weather radar live feed with the regional surface analysis on our Canada weather hub to understand why a front is stalling. In the Maritimes, the 24-hour loop often shows the difference between ocean-effect snow bands and general precipitation, so you can plan travel around the Avalon Peninsula or the Fundy coast.
What limits radar accuracy?
Beam blockage by mountains or tall buildings can create blind spots, and radar typically underestimates light drizzle and very heavy rain (due to attenuation). Best practice is to cross‑reference the weather radar environment canada product with the latest Canada Weather Warnings page, which pairs radar data with ground‑truth reports from volunteer observers.
Why does the radar show precipitation that isn’t reaching the ground?
Radar detects objects aloft. In dry air, rain or snow can evaporate before hitting the surface. This is common across the Prairies in summer and in the interior of British Columbia during winter.
Can I see wind direction on the radar?
Standard reflectivity radar does not show wind. For wind fields, switch to the Doppler velocity product available on the Environment Canada radar site. That overlay reveals whether a storm is rotating or moving toward you.
How often does the radar update during a storm?
In severe weather, some stations switch to a 5‑ or 6‑minute scan cycle. The live radar above shows the most recent complete sweep, typically delayed 2–4 minutes for processing.
