A 65-year-old Erindale Woodlands woman whose SUV plowed into 16 vehicles in Cooksville, injuring some 20 people, will be in court March 21 for a pre-trail hearing.

Joycelyn Johnson is accused of dangerous driving, a charge laid by Peel Regional Police under the Criminal Code.

She has publicly apologized to all those injured in the Oct. 25, 2013 smash-up at Dundas and Hurontario streets, in Cooksville.

"I'm sorry, from the bottom of my heart," said Johnson, who also suffered a bruised stomach, neck and back pains.

The chain-reaction crash left some 20 people with an assortment of cuts, bruises and fractures, but none with life-threatening injuries.

Johnson, a retired accountant, said she was returning home and heading westbound on Dundas Street after picking up groceries. She was in the centre lane, she said, when a white car cut her off and she hit the brakes.

Johnson said her anti-lock brake system kicked in and she started to skid and hit cars.

Police said the path of damaged cars was spread across 300 metres. Officers say there's no indication a medical condition led to the crash.

Witnesses at the busy intersection described the scene as a "war zone," with smashed vehicles scattered across a stretch of Dundas Street East. A MiWay bus was also clipped.
