It would have a lot to do with spending way too much money on green energy endeavors that were poorly thought out. BTW the vast majority of these windmills were rammed into Tory friendly ridings, not Liberal friendly. The billion dollar gas plant debacle was to save four Liberal seats.
The windmills are not some plan to screw the Torries. It is just a fact that rural ridings tend to be more right wing, and it is pretty hard to put a massive windmill in a densely populated area.
The green energy act is a drop in the bucket. The real issues with hydro costs stem back to the choices made by the Harris government to create the massive, wasteful, energy bureaucracy that we have today.
They also sold out taxpayers by "balancing" the budget by selling off assets like the 407 and giving the private entity way to much power over consumers.
The Liberals under McGuinty blew open the debt following the Harris/Eves governments
And the Liberals under Kathleen Wynne are so fiscally irresponsible that they are worse than heavy spender Dalton McGuinty. Wynne is not a Liberal. She is a hard core socialist.
The debut only ballooned after the financial crisis. There is no reason to think that any other government would have acted differently. In Ottawa, with Harper and Flaherty dead set against deficits, they ran the largest deficit in Canadian history after the recession hit.
