I can tell you that as a department, and within individual offices, we are constantly doing program integrity reviews of the decisions, and going back over files and notes to see the basis for the decisions, to see whether decisions are being taken in a consistent matter, and to see whether the right information was being considered in coming to a conclusion and a decision being taken. In some cases, the verification is done after the fact to see whether the applicant has returned, or whether in fact they continued to remain in Canada. There are checks being done on documentation that has been submitted.
All of this gets fed back into an office and into the larger knowledge base in the department. We continually revise training materials. We inform our partners. They do the same type of revision on the reference material that they apply to us. I think there's quite a healthy substance supporting the decisions that are being made right now. The reality, I believe, is that most applicants are very genuine visitors and are low-risk cases. Where we wish to concentrate our scarce resources is on the more complex or challenging cases.
