This was easy enough for an international flight...I did get yelled at by the Canadian equivalent to TSA so good to know grumpiness abounds everywhere in that job...(for the record I turned my bin wrong direction).
Checking through customs was pretty easy and the staff there was polite. Mostly the area where I wandered through seemed rundown. And once at the gates, it was overcrowded and there wasn't much food selection. I did appreciate that there was a vending machine where you could convert Canadian $ to various online gift cards....but I didn't use it.
The signage was pretty good and most of the airport personnel were fine.
