Environment and Climate Change Canada issues around 12,000 weather warnings each year across the country, with alerts ranging from winter storms and heat waves to tornadoes and fog. The live ranking above shows the most recent warnings sorted by severity and region.
Which regions get the most weather warnings?
Southern Ontario and the Great Lakes corridor see the highest number of alerts because of lake-effect snow, severe thunderstorms, and freezing rain. In winter, northern Ontario weather warnings today often cover extreme cold and blizzard conditions, while coastal British Columbia faces wind and rainfall warnings year-round. Environment Canada’s weather map updates every 10 minutes, giving you near real-time coverage for your area.
How to read a weather warning
Warnings are colour‑coded and graded by risk: red means an imminent hazard (e.g., tornado), orange indicates a high‑impact event (e.g., heavy snowfall), and yellow is an advisory for less severe but still disruptive conditions. The weather warning page on BuzzLayer breaks down each category and explains the expected impacts, so you know whether to adjust travel plans or stay indoors.
How do I check environment Canada weather warnings for my city?
Go to weather.gc.ca and enter your location, or use the Canada weather hub on BuzzLayer for a quick summary. Environment Canada also issues alerts through its free weather app, so you can get push notifications for warnings in your area.
What is the difference between a watch, a warning, and an advisory?
A watch means conditions are favourable for dangerous weather; a warning means the hazardous event is occurring or imminent; an advisory is issued for less severe but still disruptive conditions. Each level tells you how soon to take action.
Can I see a live canada weather warnings map?
Yes. Environment Canada publishes an interactive national map at weather.gc.ca that shows all current warnings, watches, and advisories. BuzzLayer’s weather radar page also overlays warning polygons with radar imagery for a detailed view.
