In 1968 CN revealed a massive downtown development plan. This was above and beyond the existing CN Tower built in 1966. The plan called for multiple developments on CN's 104 Avenue right of way.
This "pylon" building was envisioned to have a core of 800 feet around which floors of office space could be built as needed. The skyscraper's frame was intended to look as a finished building unto itself regardless of the current floor count.
It is rumoured the concept was first brought to CN engineers by Roger Graham, then vice-president of CN for the mountain region. However, very little ever became of CN's massive plans.
