A giant airport, that usually feels over crowded with ridiculously over-priced parking rates - this is what I think of when visiting Pearson airport. What I like about Pearson is the lounges (plaza premium more than Maple Leaf) and the fact that you can walk from Terminal 1 to Terminal 3 - no train or transport required. Free Wifi helps pas the time. Not much for retail stores or kids area. Overall it's a good airport but not great.
