Lol. It also gets just left in the open. I came through YYZ from LHR a couple of days after my father in law from DEL, I was to ask someone about his lost bag but just happened to notice it amongst a bunch of others neatly to the side in baggage reclaim; so I just picked it up and walked out. Could've taken anyone else's too.
But then how bad is that anyway, because I can do the same thing at the carousel when it comes out without it ever being lost. Kind of wild there's no checks on it really.
