Leaning over the edge of the catwalk at the CN Tower. - 

Steve Chiotakis: And finally -- there's a new attraction at Toronto's giant CN Tower -- one of the world's tallest structures.

Starting Monday, you'll be able to walk outside of the observation deck up top, onto a metal see-through grate and look down 12-hundred feet below. No rails. And hopefully you won't drop anything.

Your body will be tethered to the building of course. What's not tethered, is the fee of $184 that will disappear from your wallet -- because of your fascination with heights.
