The victims first have to be assured that the consequence of their coming to the federal agency is not going to be their imminent removal from Canada. That's a very important and effective tool that unscrupulous agents use, saying “If you complain, you will be removed.”
And I have to say that in my experience with the local authorities, at least in Manitoba they have been very good. They assess the problem and in many cases have been part of the solution of the problem.
