He will also not be allowed to drive for two years after he is released.
Raymond, now 21, was behind the wheel of a car with three teenaged girls as passenger on July 24, 2010 when he lost control and crashed into a tree in the Town of Mount Royal. Justine Rozon, Claudia Di Iorio and Evelyne Méthot suffered serious injuries.
He pleaded guilty to one charge of dangerous driving; the nine other charges he was facing were dropped.
Raymond broke down and sobbed throughout the sentencing hearing, during which the young women described their mental and physical injuries resulting from the crash.
They also took the time to wish him well, saying that their ability to heal was linked to his willingness to rehabilitate himself.
After hearing their statements, Raymond turned to face the gallery where his victims were seated with their families to express his regret, issuing a "great, great apology" for his crime.
The girls and their families were shocked last April when Raymond's sentencing was delayed so that he could finish school.
Rozon's mother Josée Turcot said her daughter had spent the last two-and-a-half years in hospital because of injuries sustained in the crash, preventing her from finishing high school. Rozon is now home, but has to return to hospital frequently because of recurring infections.
"She turned 19 in October. She should be finishing CÉGEP. He is going to finish his CÉGEP, and she hasn't finished high school," Turcot said after the judge agreed to push back sentencing from April 10 to June.
