One of the first to get involved in the glass floor action, this 342m-high ‘don’t look down’ experience in the heart of Toronto first got going back in 1994.

The view of the Toronto Islands is pretty stunning, but arguably the better-known novelty at the CN Tower can be found in their glass-built elevators.

Glass was first installed in the lifts in 2008, establishing a world record for the highest glass floor panelled elevator in the world – a fairly specific record we think you’ll agree.. 

It is a decent experience, but we think we’d have to choose the Chinese glass pathway or the Chamonix glass box as our ultimate my-my-god-is-it-time-to-panic-yet experience.
