I know it's a strange place to start, but the last thing I had to do before getting on the plane was mail a hydro bill. It took me the better part of 20 minutes to find a mailbox at the airport. But they had one.
It was pretty crappy in Toronto when I left. My flight was running a bit late so when we should have been boarding, it was just arriving.
Little known fact: Pearson has people who clean the flight-information monitors not only on the front, but around the back too.
