The only thing I would add is that the Canada Border Services Agency wasn't part of our original audit, because our intention was to look at the reforms that the immigration department was bringing to the student visas. We can't ignore when we find weaknesses. That's why we ended up going to Canada Border Services Agency to determine what was happening with individuals who hadn't left the country when their permits expired. We felt like we had a gap, and we were trying to fill it.
We can't issue a recommendation to an entity that's not in our audit, but I'm very happy to see CBSA here to help support a good study of this.
