Why were you escorted out ? When I worked at the airport, typically when someone was being made to leave the country, it happened three ways'
1- Passenger went to the Immigration office and gave their orders to the office saying they were in the airport and leaving, after plane left, immigration came to the counter to confirm passenger was ON the aircraft, and that the plane had LEFT
2- Passenger came to the counter checked in, the IRCC escorted them to the aircraft, waited for the aircraft to leave
3-Passenger came to the counter, checked in,I would be given the orders, the IRCC or other government escorts had tickets as well, they would be seated in predetermined seats on aircraft, and EVERYONE would leave on the aircraft TOGETHER. Sometimes it was both deportation and extradition (Deportation because they were here without authorization, extradition, wanted for a serious crime elsewhere)
Note, number # 3 was seen only rarely. These individuals tended to be high risk, and since I worked flights to the United States, the escorting individuals tended to be from the State where the individual was being sent too, as well as from the DOJ, and more than likely they were in chains/cuffs
So why were you escorted out ? You’d know why . Immigration doesn’t go to the expense of escorting out without very good reason
