Blizzard and wind warnings are in effect for the Barrie, Midland and Collingwood areas.
All school buses and vans in the Simcoe County area have been cancelled on Monday due to the inclement weather.
Schools in the north and west zones are closed, however, schools in the south and central zones remain open for student learning.
Environment Canada issued the warnings, saying dangerous snow squalls with blizzard conditions and strong wind gusts up to 90 km/h will continue Monday morning.
The weather agency says some areas could receive between five and 10 centimetres of snow.
Environment Canada is warning the high winds and snow may cause very poor visibility, making travel hazardous.
“Consider postponing non-essential travel until conditions improve,” the warning reads. “If you do travel and become lost, remain where you are until the blizzard has passed.”
The weather agency is also warning the high winds may cause power outages and damage to structures and trees.
“Damage to buildings, such as to roof shingles and windows may occur,” the warning reads. “High winds may toss loose objects or cause tree branches to break.”
Officials say conditions are expected to improve later on Monday as the winds weaken.
