Interesting facts about the CN Tower

1. What is the CN Tower?

The CN Tower is a concrete observation and communication tower located in the Downtown area of Toronto, Ontario, Canada.

2. How tall is the CN Tower?

At 553.3 meters-high (1,815.3 ft), the CN Tower was the tallest free-standing structure in the world for over 32 years. From its opening until 2008 it held this record until it was surpassed by the Burj Khalifa in Dubai, United Arab Emirates.

It held the record for being the tallest tower in the world 2 years longer until it was surpassed in 2009 by the Canton Tower in the Haizhu district of Guangzhou, China.

At the moment, the CN Tower is still the tallest free-standing structure on land in the Western Hemisphere and the 9th tallest free-standing structure in the world. It will drop to place 10 though when the Jeddah Tower opens its doors.

3. Where is the CN Tower located?

The CN Tower is located in Downtown Toronto, the main central business district of the capital of the province of Ontario in Canada.

It is built on an area that is called “Railway Lands,” which was originally a railway switching yard until it got moved to a better location outside of the city. The land was previously owned by the Canadian National Railway.

Right now, the area is a mixed-use development area with for example the residential neighborhood CityPlace in the west and is home to the CN Tower and the Rogers Center, a large sports stadium.

4. Who built the CN Tower?

The Canadian Nation Railway is Canada’s largest railway company. It has the most revenue and the largest railway network and serves all of Canada and the south of the United States.

Since the 1960s, the company has been known as the “Canadian National” and was a government-owned corporation from its incorporation on June 6, 1919, until its privatization in 1995.

Apart from the railway network, the company also owns various other assets, including media companies, so it’s the Canadian National Railway who came up with the idea to build the CN Tower.

5. When was the CN Tower built?

The original idea of the CN Tower came in 1968. The Canadian National Railway wanted to build a large communication tower to better serve the Toronto area.

By that time, the Canadian National Railway was a massive corporation, and not very humble as well. So the other reason it wanted to construct a massive tower was to emphasize the strength of the Canadian industry and most particularly, the power of the CN.

The tower was also to serve as one of the world’s top entertainment destinations and achieve international recognition as the world’s tallest tower.

The plans developed over the years and became concrete in 1972 when both a design and location was proposed. After a period of thorough testing, construction of the towers started on February 6, 1973, and was completed in 1976.

6. Why was the CN Tower built?

Toronto was a booming city in the 1960s and early 1970s and a lot of tall buildings were constructed during this period. Multiple skyscrapers were constructed during this period in the Downtown Area of Toronto.

These tall buildings caused a huge problem as it severely lowered the quality of broadcast signals. Antennas of over 300 meters (980 ft) were already necessary to maintain coverage for everybody in the area.

The core idea behind building such a tall structure was to make it possible to rent out “hub space” for people owning satellite dishes, and for whom the new skyscrapers caused disruption in the signal.

7. The CN Tower can be seen from really far

Unsurprisingly for such a tall structure, on a clear day, the CN Tower can be seen from really far in all directions. It can be seen from:

  • 40 kilometers (25 mi) to the north from Aurora.
  • 60 kilometers (37 mi) to the east of Toronto in Oshawa.
  • 58 kilometers (36 mi) southwest of Toronto from Hamilton.
  • 40 kilometers (25 mi) west of Toronto from Milton.
  • 48 kilometers (30 mi) to the south of Toronto from Fort Niagara State Park in the U.S. state of New York.

8. The Antenna wasn’t raised by a crane

The construction of the CN Tower was a massive undertaking. Especially the main level which required twelve steel and wooden bracket forms to be raised to the top.

For this, 45 hydraulic jacks were attached to steel cables that were strung to a temporary steel crown which was anchored to the top of the tower.

The final part was raising the massive antenna to the top, and this was supposed to be done by the cranes as well. Fortunately, the US Army offered a Sikorsky S-64 Skycrane helicopter up for sale during construction, which was subsequently bought and used.

The helicopter, which was named “Olga,” was first used to dismantle the cranes on top of the tower, and then flew the antenna, which consisted of 36 sections, up to the top of the tower.

9. The location wasn’t exactly what CN expected

The CN Tower was officially opened to the public on June 26, 1976. There was one problem though that the creators didn’t envision.

After the cancellation of the “Metro Centre” during the Tower’s construction, the CN Tower found itself standing lonely on the Railway Lands which had basically become an industrial wasteland. To make things even worse, the tower wasn’t very accessible to the general public.

It went this far that one of the project architects commented that “Under such ludicrous circumstances Canadian National would hardly have chosen this location to build.”

10. The area boomed afterward

The tower was standing lonely on the Railway Lands for several years, but things finally started to change in the 1980s.

In 1984, the Toronto Convention Center was built just next to the CN Tower, followed by the Rogers Centre in 1989.

The biggest change came with the completion of the construction of the Skywalk in 1989 which directly connects the CN Tower with the nearby Union Station railway and subway station, and also connects to the PATH, the city’s underground pedestrian system.

15. The original plan of the tower would have been much shorter and included a tripod consisting of three independent cylindrical “pillars” linked at various heights by structural bridges. One engineer widely noted that “people would surely pay more for an observation deck that is located higher” so this was taken into account.
