CN Tower

Toronto's needle in the sky and Canada's tallest structure/Towers & Skyscrapers

The CN Tower was the world's tallest free-standing structure from 1975 until the Burj Khalifa overtook it in 2007. Its glass floor at 342 meters lets visitors stare straight down at Toronto, which is a great way to discover if you're afraid of heights. The tower flexes up to 1.1 meters in high winds.
