If you’ve ever stood at the base of the concrete giant in downtown Toronto, you know that dizzying feeling of tilting your head back until your neck cracks. It’s huge. Honestly, the height of CN Tower Canada is one of those things that looks impressive in photos but feels almost impossible when you’re standing right under it.
Back in the day, specifically from 1975 to 2007, this was the undisputed king of the world. It held the record for the tallest free-standing structure on the planet for over three decades. Even though the Burj Khalifa and the Tokyo Skytree have since swooped in to take the crown, the CN Tower remains a beast of engineering that defines the Canadian skyline.
How Tall is the CN Tower Exactly?
Let's talk numbers. The official height of CN Tower Canada is 553.33 meters. For those of us who still think in feet, that’s about 1,815 feet and 5 inches.
But here’s the thing: "height" depends on what you’re measuring.
If you just want to know where the concrete stops, you’re looking at the roof at 457 meters (1,500 feet). Above that, you’ve got a massive steel antenna that adds another 96 meters of height. That antenna wasn't just for show; it was the whole reason the tower was built. In the 1970s, Toronto was having a massive skyscraper boom. All those new buildings were messing with TV and radio signals. The solution? Build something so tall that nothing could block the waves.

Breaking Down the Levels
You don't just go to the "top." There are actually several different heights you can hang out at, depending on how much you like (or hate) adrenaline.
- The Glass Floor and Outdoor Terrace: This sits at 342 meters (1,122 feet). If you’ve never stood on a glass floor that high up, it’s a trip. You’re basically looking down through several layers of reinforced glass at the tiny ants (people) below.
- 360 Restaurant: This is slightly higher at 351 meters (1,151 feet). It rotates once every 72 minutes. You can eat a steak while the entire city of Toronto slowly circles around you.
- The EdgeWalk: Now we're getting serious. At 356 meters (1,168 feet), people literally strap into a harness and walk around the outside ledge of the main pod. No hands. Just you and a very long drop.
- The SkyPod: This is the highest point the public can reach. It’s a separate elevator ride up to 446.5 meters (1,465 feet). On a really clear day, you can actually see the mist rising off Niagara Falls and even the skyline of Rochester, New York across Lake Ontario.
Why the "Free-Standing" Part Matters
You’ll always hear people call it the "tallest free-standing structure." That’s a very specific term in the world of architecture. Basically, it means the tower supports its own weight. It doesn't use guy-wires or cables to stay upright, unlike the KVLY-TV mast in North Dakota, which is technically taller but would fall over if you cut its "leashes."
The CN Tower is basically a massive hollow needle made of post-tensioned concrete. It's incredibly heavy—about 118,000 metric tonnes. That’s roughly the weight of 16,000 elephants.
Lightning and Wind
Because of its height, the tower is basically a giant lightning rod. It gets hit about 75 to 80 times a year. Engineers actually built a massive copper grounding system that runs all the way down to the bedrock so the electricity just passes safely into the earth.

And then there's the wind. At the top, the tower is designed to sway. If it were completely rigid, it would snap. Instead, the main pod can sway about 23 centimeters (9 inches) from the center. It’s barely noticeable when you’re inside, but it’s a vital bit of physics that keeps the whole thing standing during those Lake Ontario winter storms.
Is it Still the Tallest?
Kinda. It depends on where you live. In the Western Hemisphere? Yes, it's still the tallest free-standing structure on land. One World Trade Center in New York is shorter at 541 meters (1,776 feet).
Globally, though, it’s been bumped down the list. The Burj Khalifa in Dubai shattered all records in 2007, standing at a mind-blowing 828 meters. Then the Tokyo Skytree came along at 634 meters.
Even so, for a structure that was "topped off" in April 1975, the fact that it’s still in the top ten globally is wild. It was built by 1,537 workers who pulled 24-hour shifts, five days a week, for 40 months. And here’s a crazy fact: only one person died during the entire construction, which, considering the safety standards of the 70s and the insane height, is a bit of a miracle.

Pro Tips for Your Visit
If you’re actually planning to go up, don't just show up at noon on a Saturday. You’ll be waiting in lines forever.
- Go at Sunset: This is the gold standard. You get the daytime view, the "golden hour" for photos, and then you get to see the city lights flicker on.
- Book the SkyPod Early: It’s a separate ticket and it fills up fast. If you want that extra 100 meters of height, plan ahead.
- Check the Weather: If it’s cloudy, you’re literally paying to stand inside a cloud. You won't see a thing. Check the visibility report on the official website before you buy your tickets.
- Dine to Skip the Line: If you book a reservation at the 360 Restaurant, you usually get "complimentary" access to the observation levels, which saves you the separate ticket price (though the meal isn't cheap!).
What to Do Next
The best way to truly appreciate the scale of the tower is to see it from a distance before you get close. Head over to Trillium Park or take the ferry to the Toronto Islands. From there, you can see how the tower dwarfs every other skyscraper in the city.
Once you’ve got your photos, take the trek to the base at 290 Bremner Blvd. Buy your tickets online to save about 15% compared to the walk-up price. If you’re feeling brave, the EdgeWalk is the ultimate way to experience the height, but even just leaning against the floor-to-ceiling "Window Walls" on the main level is enough to give most people butterflies.
Check the local wind forecast before heading out. If winds exceed a certain threshold, the outdoor terrace and EdgeWalk will close for safety, though the indoor levels almost always stay open.
