With its microwave receptors at 338 m (1,109 ft.) and at the 553.33m (1,815 ft., 5 inches) antenna, the CN Tower swiftly solved the communications problems with room to spare and as a result, people living in the Toronto area now enjoy some of the clearest reception in North America.

2011 – The first of its kind in North America, EdgeWalk is the world’s highest full circle hands-free walk on a 5 ft (1.5 m) wide ledge encircling the top of the CN Tower’s main pod, 356m, (1168 ft, 116 stories) above the ground.

It takes only 58 seconds to get from the base of the tower to the LookOut level, which stands 1,136 feet in the sky.
