We see that all the time. We cover an area of Toronto, the Parkdale neighbourhood, that has a very large Tibetan community. We see a lot of cases where people have sort of de facto adopted children, in part because that's a cultural practice and in part because, as diasporas living in India and Nepal, they don't have access to legal adoptions, so it's not an option to do a formal legal adoption.
In cases like that, those kids are not dependants, strictly, under our definition of family and so, again, the only way in which you can bring those kids to Canada is if you are successful on a humanitarian application—again, that's a discretionary decision, it is uncertain, and the only requirement that an officer needs to meet, in terms of making that decision, is that it be reasonable.
In the end, what can happen is that children who have been taken care of, taken in at a young age and cared by the people they see as parents, can be refused because they don't meet our definition of family.
So, there needs to be an understanding that family is a much more complex term than the nuclear family that we think of.
