Working at over 1,000 feet, there was still little safety in terms of working-at-heights regulations. Reaching 553.33 meters – 1,814 feet, 5 inches – it is still the tallest building in the western hemisphere.Īll About The Contractors Who Built the CN Tower ![]() It took 1,537 contractors working 24-hour days five days a week to complete the project. Construction started in February 1973 and opened to the public in June of 1976. When the final piece was attached, the tower became the tallest freeform building in the world.Ĭonstruction of the CN Tower took 40 months. Each piece was hoisted up by the Sikorsky S-64 Skycrane helicopter. The CN Tower antenna was built in 44 different pieces. As the concrete was poured and then began to harden, the form was tightened, shrunk, and then gradually raised, creating the tapered look of the tower. This mold was a slipform mold that was supported by a ring of climbing jacks powered by hydraulic pressure. The actual tower itself was constructed by pouring concrete into a mold. At first, over 56 tonnes of earth was removed to build the foundation of the tower. The construction of the CN Tower began on February 6, 1973. Originally meant to be a landmark of a major railway hub, the increasing issues of telecommunications were what led the architects to design a tower that could help solve the problem while still representing the message desired by the Canadian National Railway Company. It was built by Canadian National Railway Company as a way to highlight the power and strength of the railway company and of Canada as a whole. The CN Tower was designed by John Andrews, Webb Zerafa, E.R. It already surpassed the height of all other buildings partway through construction. The skyline of the city changed dramatically before the tower was even finished. Once it was completed Toronto was often regarded as having the clearest reception for radio, television, and communication waves in North America. The CN Tower was built to act primarily as a radio tower to help solve this communications issue. The ability to communicate and receive signals was being interrupted – not a good sign for a budding city. Radio waves that used to travel at lower levels across the city began to be interrupted by new slabs of concrete and steel structures. The CN Tower was built with the purpose of fixing a telecommunications issue that started to be seen after the building boom began and there were taller buildings being built. More skyscrapers and tall buildings were being built as more people were moving to live and work in the big city. By 1970 that number had increased over 150%, up to more than 2.5 million people. In the 1950s, the city’s population sat around 1 million. ![]() In fact, the second half of the 1960s was seen as the transformation of Toronto into a modern city.Ī single-line subway, the TD Center, New City Hall, and major expressways helped to signal and speed up the growth of the city.

An iconic structure that is recognizable by its shape and form, this building impacted the skyline of Toronto, Ontario forever.īuilding an iconic landmark unlike any other may sound like a good reason, but the purpose of building the CN Tower was much more practical.
