The driver in a crash that killed a grandmother two years ago pleaded guilty on Tuesday in a Brampton, Ont., courtroom full with members of the victim's family.

Mandeep Rai pleaded guilty to impaired driving causing death, obstructing justice and breach of an undertaking.

In September 2009, Doris Byrne, 88, was killed when the car she was in with her daughter was slammed by Rai's SUV while stopped at a red light on Dixie Road near Highway 407 in Brampton.

Doris's daughter, Peggy, escaped without injury in the collision that also involved two other vehicles.

"She was the most wonderful lady that got put on this earth," Doris's daughter-in-law Irene Byrne told CTV Toronto on Tuesday.

About 17 members of Doris's family crowded into the courtroom to hear Rai admit to his crimes.

"I don't want revenge on the guy," said Bill Byrne, Doris's son. "I just don't want him to do it to anybody else."

According to police, Rai lied to officers and hospital staff about his name for about eight hours after the crash. He had been convicted of impaired driving one year earlier.

At the time of the crash, Rai was out on bail for a dangerous driving charge. He wasn't allowed to drink, or to drive and he wasn't allowed in Peel Region.

In 2008, when Rai was convicted of drinking and driving, he was handed a $900 fine and a one year driving prohibition.

Rai's sentence hearing is scheduled at a Brampton court for Jan. 18, 2012 at 9 a.m. Victim impact statements will be read in court and the judge's decision is expected 10 to 14 days later.
