What is the appropriate sentence for a conviction of sexual interference in a sexual assault case?

The first hypothetical, (R v. L.(C.), involved a conviction of sexual interference. The appellant was a 50-year-old man and the complainant was a 15-year-old high school student. One time, while in a car, the appellant touched the complainant’s upper thigh area and tried to put his hand between her legs. A second time, the appellant led the complainant to a basement and tried to touch her breasts and her legs and tried to kiss her. The appellant was a trusted friend of the complainant’s family, who the complainant called uncle. The court found there to be “something of a breach of trust” by the appellant and imposed a 90 day intermittent sentence to be served on the weekends, finding the sentence satisfied all of the relevant sentencing objectives (para. 85).
