Zamir Simas-Mamani was convicted of choking to render the complainant incapable of resistance and sexual assault.
The court considered fundamental sentencing principles, including proportionality, gravity of the offence, offender responsibility, and the totality principle.
The assault involved repeated choking into unconsciousness, removal of clothing, and various sexual acts without a condom, lasting over an hour.
The court emphasized the brutality and inherent dangerousness of choking as a means to facilitate sexual assault, citing R. v. Lemmon and R. v. Finney.
Aggravating factors included the lack of condom use, the offender's criminal record, the victim's ongoing psychological and physical repercussions, the significant size and strength discrepancy, and the duration of the attack.
The court imposed a sentence of eight years for sexual assault and eight years concurrently for choking, with a two-year credit for pre-trial custody, resulting in a net sentence of six years.
Ancillary orders included a DNA sample, 20-year Sex Offender Information Registration, a lifetime weapon prohibition, and a no-contact order with the victim during custody.
