Toronto, ON M5V 2T6
At 553.3 meters, this is one of the world's tallest building. Since its spectacular opening in 1976, the CN Tower has hosted close to two million visitors a year. One of the most exciting ways to see the world is from the exterior, glass-floored observation deck, located 342 meters above the ground. Or you can go up to the Space Deck at 447 meters, the world's tallest observation deck with a 160-kilometer view. The revolving 360 Restaurant and Horizons Bar complete the dizzying picture.
