Peel police allege that Robertson was travelling at a high rate of speed on June 18 when he violently collided with the Volkswagen SUV and then hit a Honda that was stopped westbound on Countryside Road at the red light.
The Volkswagen SUV driven by Ciasullo careened into a light pole, which fell onto the family trapped inside.
