Since pretty much every flight must go through yyz it seems (no matter how far it takes you out of your way) Ive found myself on many occasions wandering through this airport killing time between flights (I got bored of wandering so I figured I would write a yelp review). Anyways I don't have much in the way of complaints, yvr went through a lot of modernizing for the olympics and it definitely shows. Yyz looks a bit dated in comparison. I like the fact that they have a Tim hortons directly after domestic security, clearly they know what is important to travellers.
Any airport that charges for wifi loses at least a star from me, many other airports have it for free, so should yyz!
