The CN Tower in Toronto was opened on 26th june 1976 and until September 2007 it was the tallest structure in the world until the Burj Khalifa in Dubai was constructed.
I made my visit in July 2015.
The CN stands for Canadian National Railway who wanted to build a large TV and radio communication tower to demonstrate the strength of the Canadian industry.
There are now different categories to determine the official heights of buildings around the world. Freestanding, structure, building and tower. The CN building is a tower of which it held the record for being the tallest in the world for over 3 decades.
At 553.33m tall, with 1,1776 and 114 flights to the top.
There are 3 observation decks. Skypod at 447m. Indoor observation level at 346m and outdoor observation area at 342m.With 360 views of the City.
The world's first glass floor was also opened on June 26th 1994 and is accessed at 342m.
Load tests are performed annually on the 2 1/2 inch thick glass and measures 23.8 square meters. It is 5 times stronger than it needs to be and should 35 moose ever ascend the tower it would support their weight.
