Central and northeastern Ontario are facing heavy snow and icy precipitation through Monday, with strong winds creating hazardous or near-impossible travel conditions. Hardest-hit areas, including Timmins, Sault Ste. Marie, and Sudbury, could see 40-50+ cm of snow, with lingering snowfall continuing into Tuesday morning
A major winter storm is delivering heavy snow and blizzard conditions to northern Ontario, particularly along the Trans-Canada Highway. By Monday morning, more than 2,200 km of highways were closed in the northeast, including a nearly 800-km section of Highway 11 from Longlac to North Bay.
With a potential of 30-50+ cm of snow, coupled with wind gusts between 50–90+ km/h, travel will likely be treacherous, if not impossible, through Monday.
