York Regional Police say a four-year-old boy and 10-year-old girl have died after a single-vehicle crash in Vaughan on Sunday.
Police were called to a home on Athabasca Drive, south of Dufferin Street and Kirby Road, at around 12 p.m.
Investigators said a man and two young siblings, a four-year-old boy and 10-year-old girl, were out riding their bicycles when a neighbour came over to assist with a bike chain.
Officers had initially said Sunday the girl was 11 years old.
“They were out in the driveway on their own property when the vehicle it sounds like lost control, went off the roadway and collided with all of them,” Const. Laura Nicolle told reporters at the scene.
The children and a man were all rushed to hospital. The boy and girl sustained critical injuries and the man suffered non-life-threatening injuries.
The boy later died in hospital, police said Monday morning, and in a late-day update, officers confirmed the girl also died in hospital.
The driver of a black Mercedes sedan, a 16-year-old boy from Richmond Hill, was arrested at the scene. He was initially reported to be 17.
Police said he will be charged with two counts of dangerous operation causing death, two counts of criminal negligence causing death, dangerous operation causing bodily harm and criminal negligence causing bodily harm.
Anyone with information on the incident is asked to contact police at 1-866-876-5423 ext. 7704 or Crime Stoppers anonymously at 1-800-222-8477.
