First of all, I'm sorry for misunderstanding your question. I know this is a serious problem.
As I understand it, there is a combination of issues that make it difficult. One, of course, is just the problem we have with the backlog, which is very long and growing. Second, there are difficulties in some cases in determining whether or not the children we're talking about are necessarily the biological children--and you've mentioned DNA testing.
I know the fees that are levied are difficult. As you know, we've already started to lower the right of permanent residence fee. I understand the concern for people who aren't necessarily in a position to afford to pay those kinds of fees. I can assure you that one of the things I would love to do is be able to start to lower fees for people who have the least means to pay them.
I think there are a number of factors. One of the easiest to resolve is the backlog, but it requires a bit of a plan and some resources to do that. Some of the other problems are less easy to address because they have to do with working with systems that are in place in other countries, where sometimes it's difficult to identify whether or not children are actually the children of the refugees making the claims.
