Hi! I have a brother in canada who overstayed in canada. He has a work permit before but it already expired. i think its almost 5years of living illegally in canada. however, he decided to just go home to the Philippines. i am very worried that he might be detained if the airport personnel will discover that he is overstaying in canada.. I just want to ask if what will really happen if thats the case? thank you in advance to those who will response. I really need your help.
