CN Tower looms large over the city of Toronto. The idea for the iconic communications and observation tower dates to the late 1960s when Canadian National Railway wanted to build a structure that would, in part, symbolize the railroad’s strength. The tower, built on former railroad right-of-way, opened to the public in June 1976. Canadian National sold the tower in 1995. Today, the tower is the centerpiece of the entertainment center along Front Street. The tower, which is home to a rotating restaurant in addition to the observation deck, is within walking distance of the Rogers Center, Union Station and the 17-acre Roundhouse Park.
