Environment Canada issues weather warnings for hazardous conditions across the country, from blizzards in the Prairies to heat warnings in southern Ontario. Each province and territory receives tailored alerts, with Ontario often seeing the most frequent advisories during winter storms and summer thunderstorms.
What are the main types of Canada weather warnings?
Environment Canada categorises warnings by hazard: blizzard, snowfall, freezing rain, wind, rainfall, heat, and severe thunderstorm warnings, among others. Ontario weather warnings today might include a wind chill warning for northern regions or a heat warning for southern Ontario. Each type carries specific criteria—for instance, a heat warning is issued when humidex values reach 40 or higher for two consecutive days. The Weather Warning page on Northern Focus lists current alerts by region.
