Few airports can offer a more depressing or unpleasant experience than Pearson International (YYZ) in Mississauga, near Toronto. But arriving at the airport is like Russian Roulette - fly into Terminal 3 and enjoy a world-class terminal; fly into Terminal 2 and you can survive on an old badly-designed building that has been rebuilt to some improvement; but fly into Terminal 1 and say goodbye to all that is right with the world. Terminal 1 was a disaster from the start, when some brilliant architect decided to put the parking gagrage on the TOP of the Terminal. This has essentially turned the guest areas into prisoner of the concrete garage above, as it crumbles on the cars - many of its floors are closed and near collapse, and concrete often falls right onto parked vehicles, with rusty rebar poking out everywhere. A trip in the 1960's death-trap elevators takes you to the Terminal below (if they work). Arriving in Terminal One means you will have to traverse a 1/2 kilometre concrete tunnel, hand baggage and kids in tow. The tunnel features low concrete ceilings, fluorescent lighting, and horrible 1960's 'stylised' art painted in orange on the cinder-block walls. Customs feels like an jail entrance, with a row of kiosks and unfriendly, rude officers ready to be an incovenience. Past customs and into the Arrivals area, where you can find you luggage and step outside (since there is no reason to be inside - no services, nothing) into a haze of pollution, as they have built a maze of roads, with their idling cars, at the doorstep - no light gets through at all. Leaving Toronto in the Departures level presents you with a problem: surviving the wait for your flight without any real services (shops and restaurants are pathetic), lit by awful fluorescent lights and probably breathing asbestos. Once you cross the security check there is nothing. Only a few seats left over from the 60's, and a grumpy bartended ready to sell you a $7 warm beer. I know I am very negative about this place, but this is not based on a one-time experience - I have flown from this Terminal over 15 times. This review is the result of years of pain - so please learn from it. Most airlines fly into the other two terminals now (Air Canada, and Canadian: T2; Canada 3000: T3), but there are a few charter airlines that still use T1, the largest being Air Transat. There are many other reasons you shouldn't fly this airline, but Terminal 1 is the biggest. You have been warned. *the good news is that there is talk of demolishing it soon!
