Chase Donaldson was also convicted of failing to remain at the accident scene on the night of April 30, 2010.
Keira-Leigh Carlson's parents said they were relieved the driver has been found guilty.
Len Carlson, an RCMP officer, says the verdict brings some closure for his family.
Donaldson, who was believed to be speeding and driving erratically on the night he struck Carlson, will be sentenced on Friday.
He faces a maximum of 14 years behind bars. (CKIZ)Suggest a correction
