To answer your previous hypothesis—and I'm loath to be drawn into these hypotheses because there will be judicial interpretation, without a doubt—do persons under the age of 18 deserve, and should the public expect, special protection? Yes. That's why we have specific sections of the Criminal Code that were not affected by the Bedford decision that are designed to protect particularly vulnerable persons under the age 18.
I don't agree with your scenario that anybody under the age of 18 engaging in prostitution will always be subject to criminal charges. I don't think that's correct. But it's reasonable to expect that a person under the age of 18 could be present in certain factual scenarios in certain locations, yes.
