The CN tower was built from 1973 - 1976 and was at the time the tallest free standing structure in the world. Often mistaken by tourists as, "the CNN Tower," 'CN' refers to the Canadian National Railway, which originally sponsored its construction as a radio and TV communications tower on railway-owned lands. The tower's architects were John Andrews and WZMH Architects. Today, the CN tower is the third largest freestanding tower in the world behind Burj Khalifa in Dubai and Canton Tower in Guangzhou, China.
Backstory and Context
Attractions at the tower include six high speed glass elevators, the LookOut, Sky Pod, Glass Floor, 360 Restaurant, Horizons Restaurant, Le Café and Gift Shop. Since 2011, EdgeWalk has allowed particularly daring visitors to walk the outside of the tower on the roof of the 360 Restaurant. EdgeWalk is seasonal. See the CN Tower web site for ticket availability.
Of particular interest to locals is the night lighting schedule, which beautifully honors special events and holidays. http://www.cntower.ca/en-ca/about-us/night-lighting.html
Nearby, tourists can visit the Rogers Centre (formerly SkyDome) for a Blue Jays or Argos game, Ripley's Aquarium, Steam Whistle Brewing, or the Canadian Broadcasting Centre. Historic Fort York is also close by to the west.
Accessibility note: "Everyone visiting the CN Tower is encouraged to arrive via Bremner Boulevard, for the most convenient access, drop off and parking, especially for mobility challenged visitors." http://www.cntower.ca/en-ca/plan-your-visit/hours.html
