Why is the CN Tower a significant landmark for Toronto?

The CN Tower is a significant landmark for Toronto primarily because it serves as a major tourist attraction. Standing at a height of 553 meters, it was once the tallest freestanding structure in the world and remains a symbol of the city's skyline. The tower offers visitors breathtaking panoramic views of Toronto and its surroundings from its observation decks, which draws millions of tourists each year.

In addition to the stunning views, the CN Tower features a glass floor, providing a unique perspective of the ground below, as well as a revolving restaurant that enhances the dining experience amid spectacular scenery. These elements contribute to its reputation as a must-visit destination. The tower also plays a role in various events, including light shows and celebrations, adding to its allure as a focal point of both tourist activity and local pride.

While the other options mention important functions such as hosting events or serving as government buildings, they do not encapsulate the primary role of the CN Tower in attracting visitors and representing Toronto as a cultural and economic hub.
