Very quickly, if someone shows up off an airplane undocumented and they make a claim for refugee status, then the CBSA would interview them to determine, to the extent possible, how best to establish identity. They may actually cooperate and provide us with their identity, in which case they would be reported under IRPA and directed toward the IRB to follow through on their claim. That would be somebody arriving on an airplane after shredding or destroying their document.
For mass arrival, the process is actually the same. The legislative framework remains the same. The issue with a mass arrival relates largely to volume and place of arrival. If it's a boat arrival, for example, it may be at a place where CBSA and CIC are not actually located, or the IRB, so then arrangements need to be made to allow us to logistically house and medically examine the individuals for immigration purposes, and then go through the process of establishing identity.
