"EdgeWalk at the CN Tower Since it was built back in 1976, the CN Tower has toppedthe must-visit list of most Toronto tourists. Until recently, a visit was pretty standard; hop in elevator, shoot up to the observation deck,and ogle the city from a hawk’s vantage point. While this was certainlyfine and enjoyable,the since-developed EdgeWalk experience has ramped up the Tower's bucket-list potential. Thrill-seekers can now do a hands-free, breezy circumnavigation of the tower’s roof, up at 1,168 feet. And, yes, they do perform sky-high weddings complete with elasticized rings and special attire for the big day."
