Old Man Winter packed quite the punch Saturday morning.

Eastbound 401 was shut down just east of Highbury Ave. following a multi-car collision that occurred around 10:20 a.m. Saturday.

Luckily, only minor injuries have been reported so far, although there were unconfirmed reports of a pregnant woman in a black Hyundai Tuscon injured.  Her current status is unknown.

Eastbound 401 is also open again from Plank Line to Sweaburg Road after numerous vehicles went off the roadway.

In mid-western Ontario, Highway 21 is currently closed from Kincardine to Port Elgin because of multiple collisions and deteriorating road conditions.

London police and OPP are urging motorists to slow down and drive with caution.

OPP are also asking motorists to be patient during such situations.

“There are lots of vehicles to deal with and we are trying to keep everyone as safe as possible. By backing up on the roadway, not only are you breaking the law, you putting your life at risk and the lives of other drivers and responders at risk as well. It’s just not worth it,” says OPP Constable Laurie Houghton.

Inside the city, London police dealt with 60 crashes between 8 a.m. and 2:30 p.m., thankfully no serious injuries were reported.

Meanwhile, the snow isn't done with our region just yet.

Multiple snow squall bands are forecast to continue as winds become more northwesterly by Saturday evening, single bands are expected to develop off Lake Huron from Strathroy to London and off Georgian Bay from Barrie and Collingwood to Innisfil.

The heaviest squalls could produce 15 to 30 centimetres of snow per 12 hours.
