Ignace Kayiranga was convicted of unlawful act manslaughter following a judge and jury trial.
The Crown and defence jointly submitted a custodial sentence of 9.5 years, accounting for pre-trial custody.
The court accepted the joint submission, emphasizing denunciation, deterrence, and rehabilitation.
Aggravating factors included the victim's death, the brutality of the unprovoked attack, the offender's failure to assist, and a significant criminal record including a prior aggravated assault by stabbing.
Mitigating factors included the offender's complex trauma from the Rwandan genocide, his sincere remorse, and harsh conditions of pre-trial confinement.
The court recommended substance abuse and trauma counselling during incarceration.
