E and W island...basically, not much more than the restaurant kiosks and the parkland and the Forum; so yes, you could eat, you could lounge, you could paddleboat around the pods and you could see music acts. OP in 1971was really still a "work in progress": the central part came first, resolution of the E and W extremities came later. (Even such things as Echo Beach and, yes, posthumously, Trillium Park might be seen as a consequence of the original long-term visioning.)
And I'm really not sure *how* much in the way of "educational exhibits" got off the ground--it almost seems like the furthest they got in that direction was with the Ontario North Now pavilion in 1980, and that was a white elephant that quickly became a ride attraction instead. (Provincial-government-sponsored fair-display boosterism was no match for 80s cynicism. Though a little-noted detail is how the multi-siloed form of Ontario North Now echoed that of the *former* Ontario Gov't Building on the Ex grounds across the way--almost as if to send out a message in vain: "maybe we should have stayed there".)
The pods, again, were mostly sealed enigmas atop the skywalks where, once in a blue moon, there might be *something* going on; but they seemed most of the time to project an "administrative space" vibe instead. The *real* heart of it all, destination-attraction-wise, was Cinesphere--and that first season, people really just couldn't get enough of "North Of Superior" (and perhaps justifiably so--after all, it *did* launch the IMAX empire)***. But otherwise, it's almost like Ontario Place in the beginning served more as a proto-Doors Open attraction; so if visitors were sort of "organically" immersed in its architectonics as the main raison d'etre, there you go...
***(which leaves me thinking of how that earlier opus of innovative/dazzling provincial cinematic boosterism, Expo 67's "A Place To Stand"--which did become a recurring attraction in the last days of the Ontario Government Building--didn't figure in early OP programming, perhaps because it was already at that "awkward age" and superseded by Cinesphere's offerings. Yet it's the kind of thing that might have more authentic "Retrontario" appeal today, were there a way to reprogram/revitalize OP with *that* retro-Robartsian spirit in mind)
