Check the live conditions above for your city before heading out, because a broad trough is pulling damp Pacific air into British Columbia while lake-effect snow bands develop off Lakes Huron and Erie, bringing a sharp contrast in today’s weather from coast to coast.
What is driving today’s weather across Canada?
A low-pressure system over the Prairies is drawing mild, moist air into the West Coast, keeping Vancouver and Victoria under cloud and steady rain. At the same time, a cold Arctic wedge is spilling south through Ontario and Quebec, triggering Lake Huron and Georgian Bay snow squalls that could drop 5–10 centimetres locally. The Prairies sit under a dry ridge, giving Edmonton and Calgary a sunny but chilly afternoon, while the Maritines see a messy mix of rain and wet snow from a slow-moving coastal low.
How does today’s weather compare to seasonal norms?
For early April, most of Canada is running near typical temperatures. The exception is Atlantic Canada, where a stubborn northeasterly flow is keeping highs 4–6°C below average in Halifax and Saint John. Meanwhile, Winnipeg and Saskatoon are close to their 10°C daytime norm, and the B.C. interior is slightly warmer than usual. The Weather Today page gives a full city-by-city breakdown. If you’re after a broader view, the Canada weather hub has regional maps and the latest environment canada weather alerts.
Is there any severe weather in effect today?
Yes, Environment and Climate Change Canada has posted snow squall warnings for parts of eastern Ontario and southern Quebec, and a rainfall warning for the Lower Mainland. Check the weather warning page for your region.
What should I wear in Toronto today?
With temperatures near 2°C and lake-effect snow likely, a winter jacket, waterproof boots and an umbrella are smart. The mix of wet snow and gusty winds makes layering key for comfort.
How long will this pattern last?
The Pacific trough clears by tomorrow morning, bringing a dry window to B.C. The lake-effect snow in Ontario should taper off Thursday night. The Maritime system lingers into Friday before moving offshore. For a longer look, see our weather in canada 10 days and canada weather forecast 14 days overview on BuzzLayer.
