Major Winter Storm Batters Northeastern Ontario, Triggering Highway Closures and Power Outages
A severe winter storm is unleashing hazardous conditions across northeastern Ontario, prompting widespread highway closures, power outages, and urgent warnings from Environment Canada. The storm, impacting areas from Sault Ste. Marie to Wawa and beyond, is bringing heavy snowfall, strong winds, and near-zero visibility, making travel extremely dangerous.
Storm Details and Warnings
As of 11:17 AM EDT on Monday, March 16, 2026, Environment Canada has issued an orange warning for a major winter storm. Total snowfall accumulations of 20 to 30 cm are expected in the Wawa – Pukaskwa Park region, with up to 50 cm possible in the Sault and surrounding areas, stretching north to Wawa and east to St. Joseph Island . Northeasterly wind gusts are reaching 70 to 80 km/h, creating blizzard-like conditions.
The storm is expected to continue through tonight, with snow tapering off to light snow overnight. However, the immediate threat remains high, with near-zero visibility in heavy snow and blowing snow. There is also a chance of ice pellets mixing with the snow along a line from Sault Ste.
