Since I work in that area, I'll speak from my experience.
It's definitely higher than we'd like it to be. Taking any child into care is totally against my belief. However, there are situations in which a parent is unable to provide for them at a given time, and we have to provide alternate arrangements for them. It is very difficult to find foster homes, to find families that will take in children, so it's always a struggle for us. And as much as people think we take children without reason, we have to really prove a case to the courts. So it's not that we do that flippantly.
There are a lot of children still living with families even though people might question us about why we're leaving those children there, but my experience--and I've been in this field for a very long time--is that you try to maintain that connection with family. One of the things I've found living in the north as opposed to what I found when I lived in Ontario is that the children always know their family members. They're here, and they eventually go back to them when they reach the age of 16. So if we can do anything to maintain that relationship, that's definitely what we do. But, yes, there are situations in which addictions are involved and violence is involved, and we do have to remove children for their protection.
