Yes. The abundance of case law, including the cases from the Ontario Court of Appeal, suggests that when the victim is a child, and in particular when the offender is in a position of trust or authority, jail is the norm.
I don't think they would say that it's in 100% of cases. These were in circumstances where a conditional sentence was imposed and then it was overturned by the court of appeal, and that was because the court of appeal said that you can't achieve deterrence with a conditional sentence in these cases.
