I can certainly tell you that whether the adopted child is going to be processed under the Immigration Act or under the Citizenship Act--because they now have a choice--is up to the parents.
International adoption is quite a complicated area involving a number of players, as I'm sure you're aware. There are provincial and territorial authorities who do assessments of the parents, the home, and the bona fides of the adoption. And then our visa officers overseas look at the best interests of the child. They want to make sure this is an adoptable child and not a child who has been trafficked, and if there are still biological parents living, as is often the case, that the parents have freely and completely consented to that adoption and understand what that means in terms of cutting the parental link.
There is, unfortunately, a fair degree of fraud in particular pockets of our programming, so our visa officers take extra care in terms of the best interests of the child, to make sure that is looked into. We've actually cut off a couple of countries from international adoption because of those fraud concerns.
