Toronto's CN Tower is a test for even the most extreme adrenaline junkies.
But budding dare devils now face a new challenge, as the tower's operators plan to let people walk hands-free around the outside of the 116 story structure - held in place by only a cable.
For just $175, thrill-seekers can stroll around the top of Torontoβs famous CN Tower with no guard-rail and just a 5ft (1.5m) wide see-through ledge underneath.
