Only if you don’t have a fear of heights do you want to visit the CN Tower. And if you can take a trip to the top of it will surely be worth it. The CN tower is Canada’s most famous symbol and the centre of tourism in Toronto.

Over 550 meters, it is one of the tallest building in the world; on a clear day the view is wonderful. Each year, around 2 million people take the elevator ride to the top of the tower to take in the breath-taking view at the top of the world. Once you are at the top, see if you have the courage to walk across the see-through glass floor .

If you are hungry, plan to eat at the revolving restaurant at the top of the tower. The floor in the 360-degree restaurant rotates once every 72 minutes allowing everyone a complete view of the city below. The CN tower has broken record many times, winning such titles as World’s Longest Metal staircase ,World’s Tallest building and , most recently , World’s Highest Wine Cellar. In 1995, the CN tower was considered as one of the seven wonders of the Modern World.

Today, the top of the tower, more than 333m in the air, serves as the year-round workplace for more than 550 people. The tower’s workers help to make the world-class attractions and food there.

While at the CN tower, you’ll also have the chance to visit gift shops. You will find the CN Tower in the heart of downtown, on Front Street. On the north shore of Lake Ontario, the CN Tower is open 364 days a year(closed on Christmas Day).
