I believe that's an enforcement issue. We know from the jurisprudence, which I can speak to, that there are reported cases. Considering the advertising offence, it's most often charged alongside the material benefit and the procuring offence in cases in which people are procuring or profiting from others' sexual services.
The constitutionality of the provision is before both the Ontario Court of Appeal and the Ontario Superior Court of Justice. There is some data in the Juristat, as well, that the committee might find useful on the advertising offence.
