The CN Tower is apparently the world’s tallest building (probably not for much longer though). It also boasts the world’s highest wine cellar.
You usually have to pay to go up it in a super-speed elevator and can then walk all over the glass floor and watch the ants (sorry, people) below.
Great tip though – go for an excellent, very good value (considering the quality of the food) meal there and you get to go to the viewing bits for free. The cheapest meal to go for is lunch and they do a very good set course menu for around US$40.
