The CN TOWER inspires a sense of pride, inspiration and awe for Canadians and tourists alike. However, its origins are firmly rooted in practicality.During Toronto's building boom in the early 70's, a serious problem was developing. People were experiencing poor quality television. And it wasn't just the sitcoms. The pre-skyscraper transmission towers of Toronto stations were simply not high enough anymore.In 1972, Canadian National (CN) set out to build a tower that would solve the communications problems, serve as a world class entertainment destination, and achieve international recognition as the world's tallest tower.
