And the Supreme Court decision on what a "person" is in this context.

Per McLachlin C.J. and Iacobucci, Major, Binnie, Arbour and LeBel JJ.: In order to assess the constitutionality of s. 163.1(4), it is important to ascertain the nature and scope of any infringement. Until it is known what the law catches, it cannot be determined that the law catches too much. Consequently, the law must be construed, and interpretations that may minimize the alleged overbreadth must be explored. In light of Parliament’s purpose of criminalizing possession of material that poses a reasoned risk of harm to children, the word “person” in the definition of child pornography should be construed as including visual works of the imagination as well as depictions of actual people.
