The 553.3 metres (1,815 ft) tall CN Tower used to be the tallest free-standing structure in the world for 34 years since it was completed in 1976.
In the recent time, a lot of tall structures are being built. At least seven structures currently under construction, all of which are scheduled to be completed by 2013. Recently completed three tallest free-standing structures taller than CN Tower are:
- Burj Khalifa (828 m – 2,717; World’s tallest building)
- Tokyo Sky Tree (634 m – 2,080 ft; tallest structure in Japan)
- Canton Tower (600 m – 1,968.5 ft; tallest structure in China)
Although the record of being the "tallest free-standing structure" is broken by others, there are few other world records still held by CN Tower. Some of the records are:
- World’s highest public observation gallery – at 447 m
- World’s highest bar – at 346 m
- World’s longest metal staircase – with 2579 steps
- World’s highest and largest revolving restaurant – at 351 m
- World’s highest wine cellar – at 351 m
The second tallest structure in Canada is a 380m (1247 ft) cylindrical smokestack. The structure was constructed in 1972 by Inco Limited at a cost of 25 million dollar. Until 1987, this was the world’s tallest smokestack and was it was the tallest freestanding structure in Canada before CN Tower was built.
First Canadian Place (First Bank Tower)
The 355 m (1,165 ft.) tall (at roof level) structure in Toronto, Ontario is the tallest skyscraper and the eleventh tallest building in North America.
