The offender was convicted of historic indecent assault against his daughter, who was between 7 and 9 years old at the time.
The Crown sought 18 months' custody, while the defence sought a conditional sentence.
The court emphasized denunciation and deterrence for sexual offences against children by a person in a position of trust.
The court rejected the defence's request for a conditional sentence and imposed 18 months' custody followed by two years' probation, along with SOIRA and DNA orders.
