I will just add to what Marie-Claude said.
The definition of child pornography in the Criminal Code is among the broadest in the world. We protect children under 18. The problem, as Marie-Claude mentioned, is the age-difficult media. When there are secondary sexual characteristics, unless you're dealing with an identifiable person, it's very difficult for anyone to tell whether that person is above 18 or below 18, so a lot of that material is not captured. That's probably what Marie-Claude is talking about.
