That's actually a very good question because the asylum system is complex. I'll be very brief, and then I'll hand the floor over to my colleague Ms. Miller.
Overall, the asylum system is governed through legislation, IRPA, as well as various regulations. From those authorities we devise operating procedures for how we effect the law. When individuals go through a regular port of entry—air, land, or marine—and claim asylum, they're processed under the carriage of the CBSA. They'll first do an “admissibility to Canada” check and then they'll do an “are you eligible to move forward to apply to the IRB” check That's all it is.
When someone crosses in-between a port of entry, the local law enforcement—typically the RCMP, but you never know—would take that person back to a port of entry, where the CBSA will process him or her. Some individuals come into the country, legally or not, and then later on decide to claim asylum. They typically walk into an IRCC office. In fact, about 50% to 60% of the claims are inland, as we call it. They come into our office. We now have carriage of that individual. We'll go through the same steps—admissibility, eligibility—and then we will refer the person to the IRB.
