I think this is an example of where the department was just not acting on information it had. We had to go through their database with them to identify that there were 549,000 or so students who had expired permits, and then determine who had applied for another permit or not. That's when we identified about 39,500 who didn't apply for another permit and should have left the country, so we worked then with Canada Border Services Agency.
This collaboration is where I would expect the department to use that information to do this on a regular basis. We issued a recommendation to the immigration department, and we shared with them our analysis. I trust that they'll act on it now, going forward, with the Canada Border Services Agency.
