I understand. Thank you again for the question.
I would say that, in general, there is always reticence to report for a variety of different reasons and a multiplicity of situations that surface. Most particularly, people who arrive through smuggling channels do not necessarily have legitimate status in Canada. If you do not have a real passport or the status to be employed, as a foreign national.... It's another situation where somebody would be absolutely apprehensive to raise that.
In terms of fear of deportation, again, that is something I'm not necessarily able to speak to, but it's a natural inference.
