While driving around Toronto this fall, I encountered the 407 toll road.  Initially, the 407 sounded like a good idea as it offered a bypass to all of the traffic around Toronto.  But, you soon discover that there are no toll booths.  Instead, they take a picture of your license plate and then send you a bill.  Of course, they charge you for taking that picture as well as charging you for driving on the road.  My 3 (?)  mile excursion cost me $13 CAD.  I will avoid Canadian toll roads in the future.
