Police charged a Toronto Transit Commission bus driver Friday in connection with a December collision that killed a teenaged girl.

Dhanbir Shergill has been charged in connection with the incident.

The 28-year-old transit driver from Bowmanville faces two charges: dangerous driving causing death and failing to remain at the scene of a collision. He was granted bail the same day.

The family of Amaria Diljohn, the 14-year-old girl who was struck and killed just days before Christmas, was in attendance but declined to speak with reporters.

Det. Const. Thomas Reimer, the lead investigator on the case, didn't elaborate on the accusations the driver is facing following the court hearing, though he did say there was a "marked departure" from the public's expectations in how the bus was being driven.

Amaria Diljohn, 14, was struck and killed by a TTC bus she'd just exited just before Christmas. Today, police charged a 28-year-old TTC driver in connection with the collision. (Facebook) ​Reimer said the charges are the result of an "extensive" investigation, and said while he's spoken with some witnesses, he would still like to speak with anyone who was on the bus that night that hasn't talked to police.

Police say Diljohn was struck and killed Dec. 19 as she was crossing Neilson Road, just south of the intersection with Finch Avenue, in Toronto's Scarborough suburb. The bus was turning onto Finch Avenue when it hit her.

The bus then left the intersection. It remains unclear whether the driver was aware he had struck the teenaged girl.

Diljohn, known as "Momo" to friends and family, was pronounced dead at the scene.

An investigation revealed Diljohn had just gotten off the bus that hit her.

Accused no longer employed by TTC

At an unrelated event, TTC CEO Andy Byford confirmed the accused driver is no longer employed by the transit agency.

Byford said he was let go following an internal investigation into the incident.

At the time of the incident, Byford said the entire organization was "devastated" by the teen's death. He said TTC management would do everything possible to help the police investigation and turned over video footage from the bus.

The TTC also announced it would ramp up driver training in the wake of the fatal collision.
