The Canadian National (CN) Tower was completed in 1976, which has a height of 1,815 feet (600 meters) standing over the iconic skyline of Toronto, Canada. It held the record of being the tallest freestanding structure (until 2007, before Dubai’s Burj Khalifa was completed), and the second tallest building in the world (until 2010, before the Canton Tower in Guangzhou was completed).

Key Facts & Information
THE PHASES OF CONSTRUCTION
- The construction of the CN Tower commenced on February 6, 1973 by the Canada Cement Company.
- First phase: It began with the excavation of the tower base which serves as the foundation of the building. The tower base has a depth of 15 meters (49.2 feet) in the center.
- Second phase: The main support pillar was built with workers who were constructing a hydraulically raised slipform at the base. This was done until February 22, 1974. By that time, the structure was the tallest in Canada. In August 1974, the construction of the CN Tower’s main level started. Twelve (12) giant steel and wooden bracket forms were raised. These were used to support the main level of the tower.
- Third phase: The construction of the antenna and the main pod started on March 1975. The Sikorsky S64E Skycrane helicopter was used to lift the pieces that made up the tower’s antenna. It only took three and a half weeks due to the use of helicopters in lifting the pieces to construct the antenna, as well as the main pod. On April 2, 1975, the antenna topped off the tower. The construction ended on June 26, 1976.
- All in all, the CN Tower was constructed over a period of 40 months with 1,537 workers rotating work for 24 hours, five days a week.
- The cost of the construction amounted to 63 million Canadian dollars.
- The CN Tower weighs 117,910 metric tonnes or 130,000 tons.
THE SUBSTRUCTURES OF THE CN TOWER
- The Hollow concrete hexagonal pillar is the main portion of the CN Tower, which has the stairwells, the power, and plumbing connections.
- The TV and radio signals are transmitted by a tall metal broadcast antenna which has a height of 102 meters, located on the top of the main concrete portion of the tower.
- The tower has six elevators, which are located at the three inverted angles born out of the tower’s hexagonal shape.
- The main deck level of the tower has seven storeys. It has both a Glass Floor and an Outdoor Observation Terrace. In addition, the Lookout Level is present where both the Cafe Horizon and an observation deck are located.
- In the tower’s main deck, the 360 Restaurant is also found, where it completes a full rotation once every 72 minutes. It was recognized by the Guinness World Records in 2006 as the highest wine cellar in the world with a height of 351 meters (1,152 feet).
SUBSTRUCTURES AND OTHER FACTS
- In 2011, the EdgeWalk was opened to the public. This place is perfect for thrill-seekers as they walk around the roof of the tower’s main pod at 356 meters above the ground.
- The SkyPod, which is the highest observation deck on the tower, stands at a height of 447 meters. One can see the Niagara Falls from the area if skies are clear. Until 2009, the SkyPod held the record for being the highest public observation deck.
- The CN Tower was able to withstand an 8.5 magnitude earthquake, as well as winds that reached 420 kilometers per hour.
- The tower has become a staple and symbolic icon of Toronto’s skyline that attracts more than two million tourists every year.
- The American Society of Civil Engineers recognized the CN Tower as one of the modern Seven Wonders of the World in 1995.
