Organized, clean, but sometimes a leeeeeeetle confusing to get around in. I too have encountered the long empty hallways that some other reviewers have mentioned. In my last flight out from here i missed the left turn to the area my gate was at. I knew i had a left turn coming up so i quickly realized my mistake: The empty, off-limits looking hallway was in fact the turn I was looking for, although i couldn't help but feel like i was still someplace i shouldn't be until i emerged from the hallway where the gates were!
They get bonus points for free wifi (although that seems to pretty much be the norm now anyway!) but compared to other airports I've been in it seems a tad plain. I've been to airports with neat art on the wall, displays sponsored by local tourist spots and really grand architecture you've just gotta stop and admire, but i've yet to experience any of that here. I've only flown within Canada though, so it could just be that the fancy-shmancy stuff is in the international terminal!
