1) One of the world’s tallest free-standing having height 1,815 ft.
2) It was erected at an amazing rate of 18 ft. per day. During construction, concrete flowed from the bottom of the tower as it ascended, while aircraft-type bombsights kept the tower plumb as it went up.
3) The CN Tower can withstand 260-mph gusts.
4) The Sky Pod, a seven-story structure 1,100 ft. high, was built around the base of the tower and jacked into place as one unit. A pair of 10-ton counterweights is attached to the mast to keep the tower from swaying too much.
5) A Sikorsky helicopter hoisted the crowning antenna, for which the tower was originally erected. FM radio signals are broadcast from the base of the antenna, while television signals are sent from the top. Presently, 16 of Toronto’s media signals are transmitted from the tower.
