The offender was found guilty of assault causing bodily harm after striking her nephew in the head with a beer bottle in an unprovoked attack.
The Crown sought 21 to 30 days of imprisonment, while the defence sought a suspended or conditional sentence.
The court reviewed the principles of sentencing and the criteria for a conditional sentence, concluding that the seriousness of the unprovoked, weapon-based assault required actual incarceration to satisfy denunciation and deterrence.
The offender was sentenced to 21 days in jail followed by two years of probation.
