An office in the same strip-mall as the pool hall, or in the pool hall itself?
There was a huge public service push in the 70s to get Canadians fitter and more active. ParticipACTION is the most well-known program to come out of the effort. The trim tracks have come and gone.
Basically, they were a bunch of signs and fixtures spread out over a public park that made up a circuit of exercises. So the first sign might show someone doing jumping-jacks, with instructions for an easy, moderate, and hard level. Then 100 or so yards away, there might be wooden beam with a sign showing how to do swings over either side. Another 100 yards away, a series of posts that you were supposed to hop on and off. And so on.
The one at South Glenmore Park had 10 or 12 stations, making up a 2 km or so loop. The idea was you could walk or run between them and a do a circuit workout of variable intensity. The penultimate was a rope climb that was actually pretty high - about 15 ft. You can see the sign on the edge of the photo.
It was a cool and idealistic program. But vandalism, and wear and tear, eventually degraded the fixtures. And I'm sure someone pointed out liability issues at some point, so the trim tracks were left to fall into disrepair, and what was left of the rusted signs and worn beams were eventually pulled down sometime in the late 80s.
