Rodney Arens, who is 36, showed no emotion as Justice Kirk Sisson read his lengthy decision aloud in court in Red Deer.
Arens was found guilty of five charges — impaired and dangerous driving causing both death and bodily harm and breaching conditions by consuming alcohol.
On July 1, 2010, Arens was behind the wheel of a truck that slammed into a car at an intersection in Red Deer.
Jeffrey Chanminaraj (Chan-MIHN'-ehr-azh), who was a passenger in the car that was heading to the fireworks display, was killed and his older brother Jamie was injured.
During the trial, court heard Arens' truck sped up to beat a yellow light and was travelling nearly 80 kilometres per hour at the time of impact.
