I worked in that bright shiny new building behind the old building (which is now the Hockey Hall of Fame). It’s designated 181 Bay Street. It was completed in 1992 and we were one of the first tenants.
Prior to moving into this building, we were at the much taller First Canadian Place. Both buildings have multiple banks of elevators running through the center of the building, essentially being three buildings stacked on top of each other.
First Canadian Place had our floor laid out in a figure eight configuration. The elevator lobby and reception area was in the center, then two circular office layouts radiated out from the lobby. As such, you could either walk around the floor or cut through the elevator lobby.
But 181 Bay was not laid out that way. The elevator lobby was at one end, and the reception was in one direction. The offices were all on the periphery with some internal offices. The rest of the floor contained two elevator shafts with the two washrooms running in between them.
Because the elevator lobby was all the way at one end, in most cases, if you wanted to go from one side of the floor to the other, the most obvious path was through the washroom, which had doors on each end in the interior circular corridor. In most cases, it simply wasn’t worth walking to the elevator lobby, which was locked on both sides anyway. No such problems with the washrooms. However, I often thought it odd the architect really didn’t consider that in the design.
