with regards to who should pay the bill - the taxpayers, obviously, as we as a collective whole elected a government which supported the rebuild. Maybe you personally didn't, but our democratic system did it's job at the time, and the Hybrid option vote from what I recall wasn't even a particularly close council vote either.
In all seriousness, I don't support this line of thinking.
The idea that elections in Canada at any level of government represent the will of the people on every decision that follows over the subsequent 4 years is just unreasonable.
It presumes:
a) That there was a clear and cohesive platform point with all the facts, that the larger public could then weigh.
b) That the majority (not a plurality) voted for the candidate(s) or party(s) with said platform item.
c) That no additional material information came to light between the the election and the time of any vote to proceed.
d) That there were no other significant platform issues being voted on my voters. (a typical platform may have from 5 to more than 150 commitments, most voters are unaware of the majority of them, but even if they were,
one might support a candidate/party for positions 3, 11 and 38 and not for 19.
An election is rarely, if ever, a plebiscite on one particular project. We used to have those in Toronto, by the way. Long before you or I were born, the Yonge subway, and filling in Ashbridges Bay, among many other measures were put to the electorate specifically as stand-alone approvals. (for better or worse)

I will then add, no one would run for politics if they were personally, financially, on the hook for every decision if it went sideways, or the public later expressed disapproval. As such I can't really endorse 'sending the bill' to politicians or their donors or lobbyists for routine decisions with which I disagree, should the political winds shift.
However, I would support removing parliamentary immunities from being sued where there is a clear case of bribe-taking, or other favour-trading, or where a politician or bureaucrat clearly knew prior to casting a vote or signing off on a project that it was contrary to the public interest.
I don't mean should have known or anything fuzzy; but clear, written or video evidence or the like that the person pushing a project knew and understood it was adverse to the public interest. In such cases, I do favour the ability to sue and recover costs, in part, from politicians, lobbyists, bureaucrats or others, as I feel this would reduce poor decision making.
