The underage driver behind the wheel of a minivan that crashed – killing a 12-year-old girl – has been remanded in custody until a bail hearing next week.

The collision happened near Hurontario Street and Highpoint Side Road in Caledon at around 4:15 a.m. on Monday.

The driver of a stolen Toyota Sienna was travelling at a high rate of speed when he lost control, veered off the roadway, colliding with a hydro pole and wooden fence before ultimately crashing into a brick gate.

Police say the passenger, a 12-year-old girl, was killed upon impact.

The 14-year-old driver, who cannot be identified under the provisions of the Youth Criminal Justice Act, suffered minor injuries as a result of the crash and was later arrested. He has been charged with possession of property obtained by crime over $5,000, criminal negligence causing death and dangerous operation of a motor vehicle causing death.

The parents of the girl told CTV Toronto that they are devastated by her loss.

Her grandparents, who do not want to be identified, expressed similar sentiments on Friday, describing the girl as a “smart, intelligent, lovely.”

They say the crash “should have never happened” and that the driver should be punished appropriately.

“He should not be out. He should be locked for the rest of his life because he’s a danger to society… for all the other people. Another family may be victim, just like my granddaughter,” the grandmother said.

Both say they were shocked to see such a young boy in court wearing a burgundy prison outfit this afternoon.

“When I saw him, he didn’t look 14 years old,” the grandfather said.

A bail hearing for the driver has been rescheduled for August 3. Until then, he has been remanded in custody.

“She’s now gone and he should be locked for the rest of his life. Justice – life for life,” her grandmother said.
