York police say a 10-year-old girl has now died after she was struck by a vehicle in a Vaughan driveway.
It happened just around noon Sunday on Athabasca Drive near Dufferin Street and Major Mackenzie Drive.
Police say a Mercedes Benz left the roadway and struck two kids and their neighbour who were standing in the driveway fixing the chain on a bicycle.
Earlier Monday, police announced the girl’s four-year-old brother had died.

The neighbour, an adult man, suffered non-life threatening injuries and was treated in hospital.
Additionally, the teen boy is charged with dangerous operation causing bodily harm and criminal negligence causing bodily harm.
The 16-year-old cannot be named under the Youth Criminal Justice Act.
