What we tend to do in legislation is to incorporate the principles that are in a convention and see that they're reflected in what is done in the federal legislation. For example, here there's the focus on the best interests of the child, but there's no need to incorporate directly the language that's in the convention, or allude to it, or refer to it specifically in the legislation.
As you've stated, Canada is a party to the Convention on the Rights of the Child, for example, so we are required to bear that in mind when we—or actually you—enact legislation at the federal level.
