I always loved Ontario Place as i used to spend a lot of time there when i was a teen, but to say that it was Torontos most prized public park is in my opinion a big stretch. I would put High Park and The Islands way ahead by a country mile.
The columns are much higher then normal as per second last photo which would indicate that they are at the first level of mechanical floor, i could be correct or incorrect, regardless its moving up at a good pace.
