Jeez, Louise, this is like havin' yer our private airport.
You get on a plane at Dulles International Airport and 75 minutes later, you get off an there's the CN Tower towering over you (that's what towers do). Customs is two minutes, and then you take the underground walkway and in three minutes, you're off Toronto Island and in downtown. You take the Porter Shuttle to Union Station (5 or 10 minutes) and walk to your hotel. I will NEVER go through the hassle of Pearson again.
