A young child was killed when an SUV smashed through the window of a daycare north of Toronto shortly before pickup time on Wednesday. York Regional Police said the boy was just 1 1/2 years old. Six other children ranging in age from 18 months to three years old were also injured in the crash. One was still in critical condition hours later. Police told a news conference that three staff members were also hurt at the daycare near Yonge Street and Nottingham Drive in Richmond Hill, Ontario Const Kevin said a driver in his 70s was arrested at the scene and police do not believe it was a deliberate act. “As you can imagine, this was a very chaotic scene. I can tell you that the initial information suggests the vehicle was in the parking one and a half and for reasons unknown, drove through the front of the window,” he said.
