Charges have been laid following the 21 car pile up on the 401 from October 2. Four people died in the crash, including two children from Mexico, when a transport failed to slow down for construction and slammed into several vehicles. That started a chain reaction crash, which included three transports. The 73 year old driver, from Quebec is in custody pending a bail hearing. He faces 4 counts of Dangerous Operation of a Motor Vehicle Causing Death, and 11 counts Causing Bodily Harm.
