Not too sure if this is where I should be posting this as the Calgary Tower is still around for us to enjoy. I just moved into Palliser south and I can sign out a pass for the Calgary tower. I found this interesting fact from the late 60's.
From Calgary Tower's Wikipedia page:
Developers deliberately misled the public, claiming the tower would stand 187 metres (614 ft), in the hopes of preventing competing developers from surpassing the Husky Tower's height record. Shortly after officials in San Antonio, Texas attempted to claim the record in announcing the completion of the 190 metres (620 ft) Tower of the Americas, developers revealed the Husky Tower's true height (190.8 meters).
