Yes, I did! This is my proof!

But, the really cool view is the one straight down when you step out on to a 6 cm (2.5 inches) thick glass floor, 113 stories above ground. Don’t worry, it’s strong enough to support at least a dozen hippos. The CN Tower has been recognized by the Guinness Book of World Records as the World's Tallest Building and it is designated a Wonder of the Modern World. You'll find it on Front St. beside Toronto's domed stadium, in the heart of the entertainment district.
