The first and most important screening tool, of course, is the application form. We have to start with what the applicant tells us about himself. If that hits against certain security screening indicators of concern, then we have the option of asking CIC to go back to the applicant and conduct an interview or request more detailed information from the applicant.
Once that information is as complete as it can be, then the information is shared with our Government of Canada security partners. They may hold information on the individual; we may hold information ourselves. Depending upon what trail we come across in the databases, it may lead us to other government departments or to foreign governments who may hold information on an individual.
