This is the coolest little airport. If you have a choice of how you're getting into or out of Toronto, I highly recommend it. Upon arriving it took me all of about 10 minutes to get my bags and through customs, and then a very short walk (unusual in any airport really) to the shortest ferry trip I've ever taken right into the city.
On the way out today, free Starbucks coffee, almonds, shortbread cookies, water and soft drinks while waiting in the lounge appointed with comfortable seating, lots of partitions, incandescent lighting and free wifi, and right on the water with a great view of the city. I'd give it 5 stars if it had a newsstand but really, this is the coolest airport I've ever been through.
