Just let me add that they use other means as well. For instance, we have at least two examples in my office of people who were trafficked into Canada; they were exploited. And they came with student visas. That decision was not their original intention. We have other people who come as visitors, and they are exploited after they enter Canada.
So the relationship between the legal means to enter Canada and trafficking is very close, and we know that at the practical level.
