CN Tower in Toronto

Opened to the public on June 26, 1976, the CN Tower is one of Toronto's most popular attractions and rightly so - it's a fascinating structure and a celebrated landmark that offers many ways to experience its spectacular height.

Curious about the CN Tower and just how tall it really is? We have your answer.

Question: How Tall is the CN Tower?


At its highest point, the CN Tower is 553.33 metres tall (or 1,815 feet, 5 inches). That measurement is to the top of the 102 metre broadcast antenna however, so visitors to the CN Tower won't actually reach that height. The rough height of the CN Tower's public observation areas are as follows:

  • The Glass Floor and Outdoor SkyTerrace are 342 metres up (1,122 feet), the equivalent of 112 building stories. And that glass floor is pretty strong. The floor has been specifically designed for visitors to have fun on it, which means you can walk or crawl across it, sit on it or even jump on it (if you dare). The Glass Floor was the world's first when it opened on June 26, 1994.
  • The LookOut level sits at 346 metres (1,136 feet), the equivalent of 113 building stories.
  • The revolving 360 Restaurant is 351 metres (1,151 feet), or 114 building stories high. If you're curious about making a dinner reservation to dine in the sky, learn more with this guide.
  • The SkyPod is 447 metres up (1,465 feet), or 147 building stories and is one of the highest observation platforms in the world.
  • And for the truly daring, the seasonal EdgeWalk experience lets you step completely outside the CN Tower at a height of 356 meters (1,168 feet). Strap on a safety harness and take a 20 to 30 minute stroll on an open platform that's 116 stories above Toronto!

Climb Those Stairs!

High speed glass elevators can take CN Tower visitors to the LookOut level in under a minute, but twice a year you can forgo the elevator and choose the stairs. There are annual fundraising stair climbs held in support of WWF-Canada (in April) and the United Way of Greater Toronto (in October). Participants must register in advance and raise a minimum pledge amount to take part.

So just how many stairs does it take to be rewarded with the CN Tower's great view? The CN Tower has 1,776 stairs between the ground floor and the Look Out level. If you're not climbing, six high-speed glass-fronted elevators can get you to the top in just 58 seconds - at a whopping 22 kilometres (15 miles) per hour.

Toronto's Most Extreme Attraction

If you've seen all there is to see at the CN Tower, or you're looking for something a little more thrilling than peering at the city below through the glass floor, you can try the CN Tower EdgeWalk. This is the world’s highest full circle hands-free walk, which is done on a 5 foot (1.5 metre) wide ledge encircling the top of the Tower’s main pod, at 356m/1168ft (116 storeys) above the ground. You'll walk in groups of six, while attached to an overhead safety rail via a trolley and harness system. 

What's Taller than the CN Tower?

In 2007 Canada had to give up some bragging rights when the CN Tower lost the Guinness World Record for tallest free-standing structure to the Burj Khalifa in the United Arab Emirates. For awhile, the CN Tower remained the world's tallest tower, but the Tokyo Sky Tree has since taken that designation.

As of June 2017, the CN Tower still held Guinness World Records for Highest Wine Cellar (designated in 2006) at 351m (1,151 ft) above ground and Highest External Walk on a Building (designated in 2011).

ACSE's Seven Wonders of the Modern World

But the Guinness record books aren't the only place where the CN Tower has been recognized as an outstanding achievement of design and construction. In the mid-1990s the American Society of Civil Engineers (ASCE) named Seven Wonders of the Modern World. According to the ASCE, the project was undertaken as

"...a tribute to modern society's ability to achieve the unachievable, reach unreachable heights, and scorn the notion of 'it can't be done'..." 2

The CN Tower was honoured on a list which included six other astounding architectural projects from around the world:

  • The Channel Tunnel (aka "the Chunnel")
  • The Empire State Building
  • The Golden Gate Bridge
  • The Itaipu Dam
  • The Netherlands North Sea Protection Works
  • The Panama Canal
