The CN Tower is Toronto’s tallest and most defining landmark. Photos of Toronto are often defined by the building, which stretches more than 550 metres into the sky.
Today, aside from serving as a hub for telecommunications across the city, the CN Tower has become a major tourist destination. Visitors can test their courage by walking across the glass floor 113 stories above the ground. The first of its kind in the world, the glass floor gives you that dare-to-walk-on-air experience, with only 2.5 inches of glass holding you 342 metres in the air. The glass floor is actually stronger than most commercial floors and has the strength to hold 38,556 kg (85,000 lbs) or 14 hippos! Or, if you dare, travel higher up the tower to the Sky Pod, another 33 storeys above ground.
The latest features at the tour is EdgeWalk, the world’s highest full-circle, hands-free walk. Visitors are attached through safety rails and harnesses and walk along the Tower’s ledge, 116 storeys above ground, to experience breathtaking views of the city below. EdgeWalk is open from spring through until fall, and is closed for the winter. Get more details at the CN Tower’s EdgeWalk site.
