this is probably more due to cronyism by the Ford government than anything. I highly doubt they just discovered this problem.
I know nothing about architecture/construction, but how much of these timelines and costs are due to the massively inefficient construction costs in Anglophone countries? Like, does it really take double digit millions and >2 years to fix some roof panels, when we can repair bridges in a fraction of that time? How much of this is going to be permitting, excess proceduralism and "environmental assessment" crap and how…
If it’s made from concrete, absolutely. Virtually every commercial building has a flat metal roof with epdm over it because it’s substantially easier to replace it every 20 years. You start on one end, cut out sections, install new roof decking and then install the membrane over it. Repeat until you’ve completed the roof.
For this specific building, everything on top of or attached to the roof needs to be removed and reinstalled. Probably everything inside the building that would be exposed to the elements when the roof is removed would need to be removed and replaced. You need heavy cranes to lift the precast concrete panels into place. If they can’t use the lightweight concrete they used in the 60s, it’s possible the foundations/footings aren’t strong enough to support a new concrete roof which would require structural reinforcements. For trades you’ll have general laborers, heavy equipment operators, steelworkers, mechanical and electrical, concrete.
Double digit millions and two years to replace a concrete roof on a huge building is not outlandish if you understand what construction labor and heavy equipment costs.
Here’s an excerpt from the Wikipedia article about reinforced aerated autoclaved concrete, Ontario has had 30 years to secure funding for this roof and decided not to:
> RAAC has been shown to have limited structural reinforcement bar (rebar) integrity in 40 to 50 year-old RAAC roof panels, which began to be observed in the 1990s
The great blue whale bones that hung from the ceiling was found beached in the maritimes, transported to Maple, and buried behind my dad's OFRI lab in an attempt to decompose the flesh and extract the bones (eventual success!). Our family dog dug it up, chewed it, rolled in it, contracted worms from it, and died. My family will forever be attached to this structure.
If anyone else went in the 80s and remembers the fire-fighting computer game and knows somewhere it can be played now, I'd love to hear about it. The graphics were quite primitive but it gave a really good basic understanding of wildland fire fighting.

And it’s a real IMAX dome screen, not the diluted version that gets the stamp these days.
I’m just glad I got to take my kids to the museum and watch a movie on the dome last year before it closed.
The last half-decade, it was a shell of what it was.

There is/was also rampant corruption ran by real mafia. Some of them are from Montreal and are on the run in Sicily. Not sure if this spread to Ontario but given the timelines I imagine it had. See Turcot collapse in Montreal. See Olympic building in Montreal.
It's just a stadium roof, what could it cost, $870M? But seriously, the city has had issues finding contractors for basic services because they'd all been banned for ties with organized crime. It's absolutely mad. Then there's what's happening at the port with all the stolen cars...

Was there something about lightweight concrete from the 1960s that would preclude its use today? Asbestos fibres?
