The offender was convicted of sexually assaulting a semi-conscious acquaintance after a party where both consumed alcohol and marijuana.
The Crown sought a sentence of two years less a day, while the defence proposed 12 to 18 months.
The court weighed the devastating psychological impact on the vulnerable victim against the offender's lack of a criminal record, positive pre-sentence report, and genuine remorse.
Concluding that denunciation and deterrence required a period of custody, the court sentenced the offender to 12 months' incarceration followed by two years of probation, along with mandatory DNA and weapons prohibition orders.
