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

Ottawa experienced an unusually heavy snowfall early in November, reaching levels not seen in several decades according to Environment Canada records. On November 9, the snow accumulation broke the previous record set in 1967.

Record Snowfall Details

The Ottawa International Airport reported 11.7 centimetres of snow, more than double the former record of 5.8 centimetres. This early snow covered the freshly turned autumn leaves as temperatures dropped late in the weekend, allowing the storm to settle in the region.

Impact and Response

The significant snowfall led Environment Canada to issue a weather warning extending into the afternoon. Ontario Provincial Police (OPP) responded to 120 collisions in the affected areas, including 19 incidents in Ottawa itself, mostly with minor injuries.

Authorities advised residents to prepare for winter conditions by installing snow tires or avoiding travel while the storm passed.
On Monday, police shared an image showing a vehicle tire covered in ice crystals and nearly bald, which contributed to the driver losing control during snowy conditions.

“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.”

Summary: Ottawa's early November snowfall shattered a 50-year record, causing traffic incidents and prompting strong winter preparedness warnings from authorities.
