If you are in the path of this system, prepare for possible travel delays and power disruptions today; Environment Canada has issued a winter storm weather forecast that brings heavy snow and strong winds across several provinces.
Where is the winter storm expected to hit hardest?
The storm will push through southern Ontario and into Quebec this afternoon, with the heaviest snowfall expected near Lake Huron and Georgian Bay. Environment Canada weather models show 15 to 25 centimetres of snow for these areas, paired with gusty winds that may reduce visibility. Residents in these regions should monitor the live ranking above for real-time alerts. For southern Ontario weather warning today details, check our winter storm warning page.
How does this compare to recent warnings?
This event is not as severe as the February 2025 deep freeze, but it is the first major winter storm warning Ontario today has seen this season. The storm is moving faster than the system that struck Manitoba last week, meaning snowfall amounts will be lower but wind chill values will drop sharply overnight. Those east of the Rockies should check Canada weather warnings for updates.
Should I drive during this winter storm weather forecast period?
Not unless essential. Reduced visibility and icy roads could make driving hazardous, especially on highways near the lakes. Wait until conditions improve, likely late Friday.
How long will the storm last in my area?
For most of southern Ontario, heavy snow will taper off by midnight Thursday. Manitoba weather warnings today may extend through Friday morning as the system moves west.
Does this storm affect the 10-day outlook for Canada?
Yes. The weather in Canada 10 days shows a cold ridge settling in after this storm, with below-average temperatures through next week across the Prairies and Ontario.
