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 3 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 Nebrija said a driver in his 70s was arrested at the scene and police do not believe it was a deliberate act.
