Toronto police charged an Uber driver on Wednesday in connection with a fatal collision on the Gardiner Expressway last week.

Police said the 23-year-old Ottawa man is charged with:

Dangerous driving causing death.

Criminal negligence causing death.

Dangerous driving causing bodily harm.

Criminal negligence causing bodily harm.

Police were called to the scene of the collision last Wednesday on the westbound Gardiner, east of Royal York Road.

The two-vehicle collision occurred when a car on the shoulder lane of the highway collided with another vehicle while trying to merge onto the highway, Const. Clint Stibbe previously told CBC Toronto.

Nicholas Cameron was killed in the collision, his mother Cheryl Hawkes confirmed to CBC Toronto on Wednesday.

She said her son was taking an Uber to the airport when the collision occurred. When asked if the ride-hailing app has reached out to the family, Hawkes told CBC Toronto Uber has not.

Responding to inquiries by CBC Toronto, Uber said in a statement: "Our hearts are with all those grieving for the loss of their loved one following this horrible tragedy. We will support the police investigation in every way possible."

Uber also said it is looking further into this situation and that the driver's access to the app was removed.

Cameron was taken to the hospital with critical injuries but succumbed the next day. Three other occupants of the two vehicles were taken to the hospital with non-life-threatening injuries.

The man charged was scheduled to appear in court on Wednesday.

Hawkes said people can make donations in Cameron's honour to the United Nations High Commission for Refugees. Cameron is the son of late CBC Toronto anchor Bill Cameron, and Hawkes, who was a longtime former CBC reporter and producer.
