CN Tower

Toronto’s CN Tower, completed in 1976 on the former Railway Lands, was built by Canadian National Railway to solve signal interference caused by the city’s growing skyline while also demonstrating Canadian engineering. Rising 553.3 metres, it became the world’s tallest free-standing structure in 1975 during construction and remains the tallest of its kind on land in North America. Its hexagonal concrete core and three-legged base were built with innovative methods, including a slipform shaft and a helicopter-lifted antenna. Long a major observation and dining destination, it also became a defining symbol of Toronto and a centerpiece of the redeveloped Railway Lands.
