Brady Robertson, 20, who was charged in the collision that killed a Caledon mother and her three young daughters, is now facing four counts of impaired driving causing death.
Peel police allege Robertson was driving at “a very high rate of speed” on June 18 when he collided with a Volkswagen at Torbram and Countryside drives.
Karolina Ciasullo, 37, and her daughters – Klara, 6, Lilianna, 3, and Mila, 1 – were all killed in the crash.
Police say after further investigation, the additional charges were laid on Sept. 8. He will appear in court today.
Robertson was originally charged with four counts of dangerous operation of a motor vehicle causing death.
He was also charged with one count of dangerous operation connected to an unrelated incident in Caledon two days prior to the crash.
Robertson was denied bail on the initial charges.
The province’s Special Investigations Unit is also investigating the fatal collision but would not confirm if police were in pursuit of Robertson’s vehicle.
