The offender, Tiago Vieira-Paulino, pleaded guilty to eight criminal charges, including unprovoked knife attacks on strangers and intimate partner violence and child abuse against his partner and her three young children.
The Crown sought an eight-month custodial sentence, while the defence sought six months less a day, primarily to avoid immigration consequences.
The court rejected the proposed sentence as manifestly inadequate, finding it would bring the administration of justice into disrepute.
The judge emphasized the principles of denunciation and general deterrence, particularly for intimate partner violence and child abuse, and the gravity of unprovoked stranger assaults with a weapon.
A global sentence of two years less a day in custody, followed by three years' probation, was imposed, with credit for pre-sentence custody.
