In what year was the CN Tower in Toronto completed? It was completed in 1976.
The CN Tower was built in downtown Toronto on the former Railway Lands as a communications and observation tower. Construction started in February 1973, and the project reached its structural high point in April 1975. The tower officially opened to the public on June 26, 1976.
At 553.3 meters, the CN Tower became a defining feature of Toronto’s skyline and a major tourist attraction. It was built by Canadian National, whose initials supplied the familiar name, although the tower is also known as Canada’s National Tower. Its original purpose was to improve television and radio transmission across the rapidly growing city.
A common mix-up is treating 1975 as the completion year because the tower was topped out then. Another is confusing completion with opening: the structure was completed in 1976 and opened that same year. It remained the world’s tallest freestanding structure for more than three decades, until Dubai’s Burj Khalifa surpassed it in 2007.
