A fanlisting is a place for all fans of a particular show, movie, actor, actress, singer, etc. to come together and build the biggest listing of people from all around the world who are fans of that subject.
This is a fanlisting for the CN Tower, which is located in Toronto, Ontario Canada. If you're a fan of the tower head on over to the rules and join to have your name displayed on the members list.
