Blowing snow and treacherous roads in the Barrie area have emergency services urging motorists to drive with caution or stay home.
"Roads are icy. If you can avoid it, stay off them," said Samantha Hoffmann, Barrie Fire Public Fire and Life Safety Officer. "If you do have to drive, slow down. Nothing personal but we'd rather not see you."
The OPP are responding to numerous collisions on the 400 and Highway 11 as a wintery blast hits our region.
Barrie Fire and Police were also busy responding to calls.
For commuters who take GO Transit, the system is initiating its winter storm protocol or snow plan at 11 p.m. tonight in a bid to prepare for Monday's commute.
The storm plan includes extensive examination of rails to ensure there isn't ice that could jam switches.
Staff will work throughout the night, extra staff is brought in and additional bus drivers on standby.
GO officials were advising passengers to give themselves extra time and stay informed, either through GO's website or social media.
"Plan your day," said Metrolinx spokesperson Anne Marie Aikins. "Just like any other transportation system it will be subject to delays and cancellations because of the storm."
