Randomness from my life over the past 6 years, with photos and video.
I have done some digging, and have a better idea of who is responsible. It seems that Transport Canada itself is in charge of these silly restrictions, and the GTAA (Greater Toronto Airport Authority) is fighting to get them lifted. Hey, that's great, they're on our side then right? Haha not really, they've been losing money at the duty free shops, so they want to make sure that people can still buy their booze! I'm pretty sure I'm going to be even more mad if someone can bring a bottle of booze on a plane and I can't bring a bottle of iced tea.
It really is sad if these restrictions get lifted because the duty free's are losing money, and not because it was a stupid idea to begin with. Transport Canada, boo to you!
