Sater was convicted of impaired driving causing death and dangerous driving causing death, after he drove his Jeep into a group standing at the scene of an earlier accident on Lougheed Highway, on February 19. 2011.
Charlene Reaveley and Lorraine Cruz were killed instantly.
Sater had consumed six double rye-and-Cokes and two Jägerbomb drinks at a bar, earlier in the evening. He fled the scene of the crash and later turned himself in.
The judge gave Sater two years credit for time served, so he will spend seven and a half years behind bars.
Outside his sentencing hearing earlier this week, Sater told reporter he would live with this every day of his life.
"Rest assured, I will be haunted for it, but at the same time there's got to be a positive way to come out of this and become a better person," he said.
The court also handed down an eight-year driving ban that will go into effect upon Sater's release from prison.
