It's important to note that—and this is part of the work of the department—in some cases, it was. Over 900 applications were denied, as a result of the fraud, through the same stream of investigation. Why was it that the fraud was detected in those cases and not in others? That is something we will undertake to review.
I would also note that there is, at times, a high level of sophistication. That's why we need to take a look at what tools we need to improve on. I think data sharing is key. If we know exactly how many letters of offer institution X issues every year and compare that against our system, right then and there, at the front end, we can make a determination that we have an issue or that we don't.
These are the types of things we're working towards for the reform of the international student program. It's not perfect. It's one step and there are multiple measures that we layer onto that.
