We do work very closely with our enforcement partners as well as police services across the country. When we are made aware of criminal activity or fraud trends that link to immigration, or that potentially link to foreign nationals coming into Canada, we're able to assess and determine whether or not we can identify those trends in future applications.
We do have measures in place now. My colleague mentioned the letter of acceptance verification. Since it's been in place, it has identified over 14,000 potentially fraudulent letters of acceptance. We were able to then refuse applicants who were not genuine students coming into Canada. We also rely on our post-secondary institutions or our provinces to tell us when students are not complying and not attending school.
