I need a location:

I first saw this footage in "Days of Fury" (1979), a mondo film narrated by
Vincent Price. The poor dudes aboard were probably Americans, because the
full footage showed their bodies being covered up by an American flag. I
think of the CN Tower in Toronto, but its construction didn't begin until
1973, and clothes worn by the rescuers looked like something from the late
'50s or early '60s.
