Dean Archibald was found guilty of aggravated assault, assault, theft under $5000, and mischief under $5000.
The aggravated assault caused severe facial fractures and unconsciousness to one victim, a building superintendent, and the other victim was assaulted while attempting to call for help, with her phone destroyed.
The Crown sought a five-year jail sentence, while the Defence proposed a conditional sentence of two years less a day.
The court considered aggravating factors, including the unprovoked and vicious nature of the attack, significant victim impact, and interference with aid, alongside mitigating factors such as harsh pre-sentence custody and the offender's delusional disorder.
The court imposed a total sentence of three years' incarceration, finding a conditional sentence inappropriate given the gravity of the offences.
