First of the season snowfall breaks over 50-year record

First Snowfall of the Season Breaks Over 50-Year Record in Ottawa

Ottawa experienced an extraordinary early snowfall on November 9, 2025, marking the largest accumulation this early in November in over five decades. Environment Canada confirmed that the snow depth recorded at Ottawa International Airport reached 11.7 centimeters, surpassing the previous record of 5.8 centimeters set in 1967.

The early snowstorm covered the city’s newly turned autumn leaves and was accompanied by a sharp temperature drop, allowing the storm to settle firmly across the region. Due to these conditions, Environment Canada issued a weather warning that extended well into the afternoon.

Impact and Response

Ontario Provincial Police (OPP) reported responding to 120 collisions, including 19 in Ottawa, mostly involving minor injuries in the eastern areas.
Authorities urged residents to take precautionary measures ahead of the weekend, such as installing snow tires or avoiding unnecessary travel during the storm’s passage.
On Monday, police shared an image of a vehicle tire covered in ice crystals and nearly worn out, which had contributed to the driver losing control.

“We know here in Ottawa that the seasons can change in an instant. Make sure your vehicle is winter-ready, beginning with snow tires! These tires weren’t even acceptable for summer weather and resulted in the driver losing control in the snowy weather.”

The early snowfall and its impacts serve as a reminder for all residents to prepare thoroughly for winter conditions to ensure safety on the roads.

Author’s summary: Early November snowfall in Ottawa set a 50+ year record with over 11 cm of snow, triggering warnings and traffic incidents, emphasizing the critical need for winter vehicle preparedness.
