The offender was convicted after trial of assaulting his son and daughter by repeatedly slapping them on the head for disciplinary reasons, and of assaulting his wife by cutting her neck with a potato peeler.
The Crown sought a 12-month custodial sentence, while the defence sought a conditional discharge.
The court found that a discharge or conditional sentence would be contrary to the public interest given the multiple victims, the breach of trust, and the serious nature of the violence in the family home.
The offender was sentenced to a global term of 120 days in jail followed by 18 months of probation.
