Buildings Breaking Boundries, CN Tower

Ontario, Canada, is home to the CN Tower, a communications and observation structure which looms over the city of Toronto. In 1975 while still under construction it exceeded the height of the Ostankino Tower, becoming at the time, the tallest free-standing structure in the world.

Canadian National, the railway company that built it, saw a need for large TV and radio communication platform to serve the Toronto area. They also wanted it as monument to the strength of Canadian industry, CN in particular.

However, in 1995 prior to the company’s privatization, the decision was taken to divest non-core freight railway assets, which resulted in the tower being transferred to the Canada Lands Company, a federal Crown conglomerate, responsible for real estate development.

At the time local residents expressed a desire to retain the name CN Tower and the abbreviation is now said to expand to Canada's National Tower, rather than the original Canadian National Tower.

At 553.33 meters, after holding the record for 31 years, in 2007 it was surpassed in height by the still-under-construction Burj Dubai. It does however remain the tallest free-standing structure in the Americas and is the signature icon of Toronto's skyline.

In 1995, the American Society of Civil Engineers declared the CN tower to be one of the Seven Modern Wonders of the World. It also belongs to the World Federation of Great Towers.
