"The CN Tower's primary function is as a telecommunications tower," stated Jamil Mardukhi, a principal at NCK Engineering. "Now it's both telecoms and tourist, but it still plays a significant part in downtown Toronto's telecommunications services."
The CN Tower was also originally intended to be a landmark for Montreal, but it became so popular that it has now become a symbol for Toronto, too.
In addition to being a telecommunications tower, The CN Tower is also an observation deck, a radio station broadcasting music programs, a nightclub, and more. It is currently the tallest free-standing structure in Canada and one of the most famous landmarks in the world.
The CN Tower, designed by John Andrews, Webb Zerafa, Menkes Housden, and E.R. Baldwin, is Toronto's most recognizable landmark. It is a popular tourist destination with observation decks, a rotating restaurant at 1,151 feet (351 meters), and an entertainment complex. The tower was built between 1976 and 1990 as part of Harbour Island International Terminal on the banks of the Port of Toronto. It was constructed by Cimico Construction Company using structural insulated panels manufactured by Wulff Engineering Laboratories.
Andrews, Zerafa, and Housden were all Canadian architects who had new designs published after they died while Baldwin was from South Carolina and worked with him on the project.
All the architects were invited to see their designs become reality, but only one could be chosen so they all got to work on it simultaneously. The winning design was decided by a jury composed of prominent industry experts who selected Zerafa's design because of its innovative use of glass and its ability to integrate seamlessly into the surrounding urban landscape.
Zerafa was born in Bulgaria in 1933 and came to Canada in 1956. He attended the University of Toronto where he received his BArch in 1958. After graduating, he went to Chicago where he worked for Richard Rogers, one of England's most famous architects. In 1966, Zerafa returned to Canada and started his own firm which grew to become one of the largest architectural firms in Ontario.
Aided in the resolution of issues posed by the building of the CN Tower's microwave receptors at 338 meters and 553.33 meters antennas. Residents in the Toronto region currently get one of the best receptions in North America. The tower itself is 459 meters high.
The antenna on the CN Tower is actually two separate structures that are mounted on top of each other. One is 339 meters high and the other is 200 meters high. They're both made of non-metallic materials (such as glass and polycarbonate) and coated with aluminum to prevent ice from forming on them during winter months.
In addition, there are three other antennas located around the perimeter of the roof that are used primarily for communications with aircraft within a radius of 50 miles of Toronto Pearson International Airport. Two are 250 meters high and the third is 181 meters high.
All together, these antennas measure 1,067 feet or 328 meters high.
The CN Tower was built as a landmark for Toronto and continues to be one of the city's most popular attractions. Opened in 1976, it is owned and operated by CNW Group/Cablevision Systems Inc. (which also owns this site). There are observation decks located at 441 meters and 484 meters above sea level offering views of the city below plus surrounding areas.
The CN Tower in Toronto, commonly known as the Canadian National Tower, is a broadcast and telecommunications tower. It was the world's tallest freestanding construction until 2007, when it was surpassed by the Burj Dubai building in Dubayy (Dubai), United Arab Emirates. The CN Tower is 604.5 metres (1,815 feet) tall with 42 floors.
The tower is located in the Financial District of downtown Toronto at 50 Bay Street near to the intersection of Queen Street West and Bay Street. It stands on land that was home to several other prominent buildings before it became available for commercial use. There are also several other businesses on site.
