The original concept of the CN Tower was first conceived in 1968 when the Canadian National Railway wanted to build a large television and radio communication platform to serve the Toronto area, and to demonstrate the strength of Canadian industry and CN in particular. These plans evolved over the next few years, and

729-458: A similar attraction entitled "Space Race." It was later dismantled and replaced by two other rides in 1998 and 1999. A glass floor at an elevation of 342 m (1,122 ft) was installed in 1994. Canadian National Railway sold the tower to Canada Lands Company prior to privatizing the company in 1995, when it divested all operations not directly related to its core freight shipping businesses. The tower's name and wordmark were adjusted to remove

It beat the previous record of −51.5 °C (−60.7 °F) that was set 28 January 1989. Kugaaruk has

1134-663: Is the tallest freestanding structure in the Western Hemisphere. As of 2013, there were two other freestanding structures in the Western Hemisphere exceeding 500 m (1,640.4 ft) in height: the Willis Tower in Chicago, which stands at 527 m (1,729.0 ft) when measured to its pinnacle, and One World Trade Center in New York City, which has a pinnacle height of 541.33 m (1,776.0 ft), or approximately 12 m (39.4 ft) shorter than

1215-577: Is to encourage and spread the use of Inuktitut. There are a few Inuit artists in Kugaaruk, including the world-renowned Emily Illuitok , (1943-2012), who worked mostly in walrus ivory and bone; and Nick Sikkuark , whose works are mainly in whale bone, caribou antler, and walrus ivory, and are characterized by "droll, macabre wit". Most women sew traditional parkas , amautiit (baby carrying parkas), and kamik (seal or caribou skin boots). Kugaardjuq School includes kindergarten to grade 12 . It

1296-490: Is very modern and includes a large south facing library, computer lab, gymnasium and science lab. Currently there are two language specialists who teach Natsilingmiutut , while the rest of the staff are southern teachers. In 2010 many of the Nunavut Teacher Education Program (NTEP) graduates, who are locals, were to become teachers in levels from kindergarten to grade 7. As the only outsiders in

1377-482: The Council on Tall Buildings and Urban Habitat both listed the CN Tower as the world's tallest free-standing structure on land , and specifically state that the CN Tower is not a true building, thereby awarding the title of world's tallest building to Taipei 101 , which is 44 m (144 ft) shorter than the CN Tower. The issue of what was tallest became moot when Burj Khalifa, then under construction, exceeded

1458-503: The John Hancock Center ), and First Canadian Place — also have excellent safety records, which suggests that the Ostankino Tower accident was a rare safety failure, and that the likelihood of similar events occurring at other supertall structures is extremely low. The CN Tower was originally lit at night with incandescent lights, which were removed in 1997 because they were inefficient and expensive to repair. In June 2007,

1539-583: The Petronius Platform stands 610 m (2,001 ft) above its base on the bottom of the Gulf of Mexico near the Mississippi River Delta , but only the top 75 m (246 ft) of this oil and natural gas platform are above water, and the structure is thus partially supported by its buoyancy . Like the CN Tower, none of these taller structures are commonly considered buildings. On September 12, 2007, Burj Khalifa, which

1620-507: The a form with a stand-alone letter ᐃ i. This fourth-vowel variant had been removed so that Inuktitut could be typed and printed using IBM Selectric balls in the 1970s. The reinstatement was justified on the grounds that modern printing and typesetting equipment no longer suffers the restrictions of earlier typewriting machinery. The ai-pai-tai column is used only in Nunavik. CN Tower The CN Tower ( French : Tour CN )

1701-590: The 1870s, Edmund Peck , another Anglican missionary, started printing according to that standard. Other missionaries, and later linguists in the employ of the Canadian and American governments, adapted the Latin alphabet to the dialects of the Mackenzie River delta, the western Arctic islands and Alaska . The Inuktitut script ( titirausiq nutaaq ) is commonly presented as a syllabary . The dots on

1782-439: The CN Tower "the world's tallest self-supporting tower" and "the world's tallest free-standing tower". Although Guinness did list this description of the CN Tower under the heading "tallest building" at least once, it has also listed it under "tallest tower", omitting it from its list of "tallest buildings." In 1996, Guinness changed the tower's classification to "World's Tallest Building and Freestanding Structure". Emporis and

1863-549: The CN Tower elevators, which established a world record (346 m (1,135 ft)) for highest glass floor panelled elevator in the world. On August 1, 2011, the CN Tower opened the EdgeWalk, an amusement in which thrill-seekers can walk on and around the roof of the main pod of the tower at 356 m (1,168.0 ft), which is directly above the 360 Restaurant. It is the world's highest full-circle, hands-free walk. Visitors are tethered to an overhead rail system and walk around

1944-677: The CN Tower has an excellent safety record, although there was an electrical fire in the antennas on August 16, 2017 — the tower's first fire. Moreover, other supertall structures built between 1967 and 1976 — such as the Willis Tower (formerly the Sears Tower), the World Trade Center (until its destruction on September 11, 2001 ), the Fernsehturm Berlin , the Aon Center , 875 North Michigan Avenue (formerly

2025-594: The CN Tower. Due to the symbolism of the number 1776 (the year of the signing of the United States Declaration of Independence ), the height of One World Trade Center is unlikely to be increased. The proposed Chicago Spire was expected to exceed the height of the CN Tower, but its construction was halted early due to financial difficulties amid the Great Recession , and was eventually cancelled in 2010. Guinness World Records has called

2106-454: The CN railways logo, and the tower's official name was renamed Canada's National Tower (from Canadian National Tower), though the tower is commonly called the CN Tower. Further changes were made from 1997 to January 2004: TrizecHahn Corporation managed the tower and instituted several expansion projects including a CA$ 26 million entertainment expansion, the 1997 addition of two new elevators (to

2187-504: The Cement Foundation Company of Canada at the time), a subsidiary of Sweden's Skanska , a global project-development and construction group. Construction began on February 6, 1973, with massive excavations at the tower base for the foundation. By the time the foundation was complete, 56,000  t (62,000 short tons ; 55,000 long tons ) of earth and shale were removed to a depth of 15 m (49.2 ft) in

2268-559: The Glass Floor and Outdoor Observation Terrace, which are both located at an elevation of 342 m (1,122 ft), the Indoor Lookout Level (formerly known as "Indoor Observation Level") located at 346 m (1,135 ft), and the higher SkyPod (formerly known as "Space Deck") at 446.5 m (1,465 ft), just below the metal antenna . The hexagonal shape is visible between the two highest areas; however, below

2349-596: The Outdoor Observation Terrace (at the same level as the Glass Floor) at 342 m (1,122 ft). One floor above the Indoor Observation Level was the Top of Toronto Restaurant, which completed a revolution once every 72 minutes. The tower would garner worldwide media attention when stuntman Dar Robinson jumped off the CN Tower on two occasions in 1979 and 1980. The first was for a scene from

2430-407: The Toronto area. The original plan for the tower envisioned a tripod consisting of three independent cylindrical "pillars" linked at various heights by structural bridges. Had it been built, this design would have been considerably shorter, with the metal antenna located roughly where the concrete section between the main level and the SkyPod lies today. As the design effort continued, it evolved into

2592-458: The brackets that support the main level, as well as a base for the construction of the main level itself. The Space Deck (currently named SkyPod) was built of concrete poured into a wooden frame attached to rebar at the lower level deck, and then reinforced with a large steel compression band around the outside. While still under construction, the CN Tower officially became the world's tallest free-standing structure on March 31, 1975. The antenna

However, one challenge faced by educators in this community is that most students read at about 3 or 4 grade levels lower than their Albertan counterparts (as of 2007). As with most schools in Nunavut, the school is under the partial authority of

2835-739: The construction, plans for Metro Centre were scrapped, leaving the tower isolated on the Railway Lands in what was then a largely abandoned light-industrial space. This caused serious problems for tourists to access the tower. Ned Baldwin, project architect with John Andrews, wrote at the time that "All of the logic which dictated the design of the lower accommodation has been upset," and that "Under such ludicrous circumstances Canadian National would hardly have chosen this location to build." The CN Tower opened on June 26, 1976. The construction costs of approximately CA$ 63 million ($ 318 million in 2023 dollars) were repaid in fifteen years. From

This is a fixed wireless service to homes and businesses, connecting to the outside world via a satellite backbone. The Qiniq network is designed and operated by SSi Canada . In 2017, the network was upgraded to 4G LTE technology, and 2G-GSM for mobile voice. Kugaaruk

3240-546: The former Railway Lands were redeveloped and the tower became the centre of a newly developing entertainment area. Access was greatly improved with the construction of the SkyWalk in 1989, which connected the tower and SkyDome to the nearby Union Station railway and subway station , and, in turn, to the city's Path underground pedestrian system. By the mid-1990s, it was the centre of a thriving tourist district. The entire area continues to be an area of intense building, notably

3321-583: The ground up. The CN Tower was the tallest tower by this definition until 2010 (see below). Taller than the CN Tower are numerous radio masts and towers , which are held in place by guy-wires , the tallest being the KVLY-TV mast in Blanchard, North Dakota , in the United States at 628 m (2,060 ft) tall, leading to a distinction between these and "free-standing" structures. Additionally,

3402-453: The ground. Over the height of the tower, it varies from true vertical accuracy by only 29 mm (1.1 in). In August 1974, construction of the main level commenced. Using 45 hydraulic jacks attached to cables strung from a temporary steel crown anchored to the top of the tower, twelve giant steel and wooden bracket forms were slowly raised, ultimately taking about a week to crawl up to their final position. These forms were used to create

3483-417: The heaviest of which weighs around 8 tonnes (8.8 short tons; 7.9 long tons). At the time, most data communications took place over point-to-point microwave links, whose dish antennas covered the roofs of large buildings. As each new skyscraper was added to the downtown, former line-of-sight links were no longer possible. CN intended to rent "hub" space for microwave links, visible from almost any building in

3564-510: The height of the CN Tower in 2007 (see below). Although the CN Tower contains a restaurant, a gift shop and multiple observation levels, it does not have floors continuously from the ground, and therefore it is not considered a building by the Council on Tall Buildings and Urban Habitat (CTBUH) or Emporis. CTBUH defines a building as "a structure that is designed for residential, business, or manufacturing purposes. An essential characteristic of

3645-444: The higher observation deck would be worth paying extra for, and the costs in terms of construction were not prohibitive. Also around this time, it was realized that the tower could become the world's tallest free-standing structure to improve signal quality and attract tourists, and plans were changed to incorporate subtle modifications throughout the structure to this end. The CN Tower was built by Canada Cement Company (also known as

3726-456: The isolation of the community, the traditional language, Inuktitut , is declining. Most people 30 and over speak Inuktitut as their first language, but the language is not being passed on to their children. In most households, a mixture of English and Inuktitut is spoken. Children understand their parents and grandparents, but respond to them in English. One goal of the Nunavut educational system

3807-640: The land and culture. Sites visited in Ontario included the CN Tower , the Hockey Hall of Fame , Queen's Park , Square One Shopping Centre , MuchMusic , Niagara Falls , Great Wolf Lodge, and the two exchange schools: Clarkson Secondary , and Hillside Senior Public School. On 28 February 2017, the school caught on fire, described as "suspicious". Most of the school burned down, the gym, reception area and high school portion were all completely destroyed, and

3888-417: The late 1960s and early 1970s, multiple skyscrapers were constructed in the downtown core, most notably First Canadian Place , which has Bank of Montreal 's head offices. The reflective nature of the new buildings reduced the quality of broadcast signals, requiring new, higher antennas that were at least 300 m (980 ft) tall. The radio wire is estimated to be 102 metres (335 ft) long in 44 pieces,

3969-484: The letters in the table mark long vowels ; in the Latin transcription, the vowel is doubled. For geminate consonants , the final consonant symbol is placed before the CV syllabic, for instance - kk u-, - nnu - are rendered ᒃ ᑯ and ᓐ ᓄ respectively.

Below the public areas—at 338 m (1,108.9 ft)—is a large white donut-shaped radome containing the structure's UHF transmitters. The glass floor and outdoor observation deck are at 342 m (1,122.0 ft). The glass floor has an area of 24 m (258 sq ft) and can withstand

4293-426: The main support pillar, workers constructed a hydraulically raised slipform at the base. This was a fairly unprecedented engineering feat on its own, consisting of a large metal platform that raised itself on jacks at about 6 m (20 ft) per day as the concrete below set. Concrete was poured Monday to Friday (not continuously) by a small team of people until February 22, 1974, at which time it had already become

4374-545: The mid-1970s to the mid-1980s, the CN Tower was practically the only development along Front Street West; it was still possible to see Lake Ontario from the foot of the CN Tower due to the expansive parking lots and lack of development in the area at the time. As the area around the tower was developed, particularly with the completion of the Metro Toronto Convention Centre (north building) in 1984 and SkyDome in 1989 (renamed Rogers Centre in 2005),

4779-502: The same year, the CN Tower reopened. In August 2000, a fire broke out at the Ostankino Tower in Moscow, killing three people and causing extensive damage. The fire was blamed on poor maintenance and outdated equipment. The failure of the fire-suppression systems and the lack of proper equipment for firefighters allowed the fire to destroy most of the interior and sparked fears the tower might even collapse. The Ostankino Tower
