A lot of good ideas but who would fund it? The City and the Province are a bit tight on the cash side, the Liberals shuttered Ontario Place because the yearly expenses were high just to maintain it.
I appreciate the question (sincerely); and would argue that neither the City nor the Province are in fact tight on the cash-side, except by choice.
The Province had, pre-pandemic, an annual budget of over 150B.
It also just under-spent, its projected spending for the last fiscal year by several billion. Far less than 100% of that one-time money would cover the entire capital cost and 100% of any potential losses for 40 years.
The province also claims to be short of money and ran deficits, even pre-pandemic, while....
Running a small business tax rate of 3.2% on profit, compared with a historic norm of 12%
Running a larger business tax rate of 11.5% on profit compared with 16% prior to the mid 90s.
Having not raised the gas tax of 14.5C per L for more than a generation (it would be closer to 24c per L today had it kept pace with inflation}
Having not followed the lead of Quebec and the Maritime provinces who raised their PST/HST by 2 points when Harper lowered it federally (maintaining the previous overall rate of 15%).
If one were to adjust for the above, allowing some elasticity (you wouldn't get 100% of the perceived revenue increase due to changed behaviour or avoidance).
Ontario would see at least 17B more in annual revenues.
That does not include potential revenues from road tolls, eliminating bad policy tax deductions, raising the provincial portion education tax to its inflation-adjusted historic level, or raising income tax rates to where
they were in the mid 90s.
For the record, I would not advocate being that punitive with taxes; but I would advocate for road tolls on all provincial highways which would be windfall sum, as would eliminating all over corporate welfare, and energy subsidies.
In the end, I. am confident that the province can balance its budget, and have significant, re-investable surplus; on which I would not put Ontario Place at the top of the list $$ should go, but it can fit somewhere in the middle.

The City of Toronto has taxes, inclusive of fees for garbage that are lower than most municipalities in the GGH and doesn't have municipal road tolls for the Gardiner/DVP.
Placing Toronto's tax rate at the median level for the GGH would raise a lot of $$$; and a fair road toll would represent several hundred million per year, conservatively.
