Name: CN in the title came from Canadian National, the railway company that created the tower.

Further Information:

The structure was completed in 1976, becoming the world’s tallest free-standing structure and world’s tallest tower at the time. It held both records for 34 years until the completion of Burj Khalifa, UAE, and Canton Tower, Guangzhou, China, in 2010. Since then, it became the third tallest tower in the world. It remains the tallest free-standing structure in the Western Hemisphere.

Key project team members were NCK Engineering as structural engineer; John Andrews Architects; Webb, Zerafa, Menkes, Housden Architects; Foundation Building Construction; and Canron (Eastern Structural Division).

The original plan for the tower envisioned a tripod consisting of three independent cylindrical “pillars” linked at various heights by structural bridges. Had it been built, this design would have been considerably shorter, with the metal antenna located roughly where the concrete section between the main level and the SkyPod lies today.
