Michael MacKinnon was found guilty of manslaughter and aggravated assault.
The court considered aggravating factors, including the use of a knife, the victims being unarmed, the severe loss to the deceased's family, and the life-threatening injuries to the aggravated assault victim.
Mitigating factors included the offender's pro-social life for 20 years, strong family support, and a diagnosis of PTSD stemming from childhood trauma and a past shooting incident.
The court rejected the Crown's submission that the dated criminal record was an aggravating factor and that the mental health issues should be given limited weight.
A total sentence of 9 years imprisonment was imposed, with 3 years concurrent for aggravated assault, after accounting for 69 months (5 years and 9 months) credit for pre-sentence custody, leaving 39 months (3 years and 3 months) remaining to serve.
Ancillary orders included a lifetime weapons prohibition and a DNA order.
