The voters within Toronto proper(the old city limits)hate the consolidation. The Liberal government didn't do anything to even modify it.
Were it not for the consolidation, Toronto would NOT be living at the mercy of the Ford brothers and the life-hating suburban haters.
It seems like deconsolidation would guarantee an ONDP sweep of the Toronto ridings, and knock the Liberals for a major loop. And almost nobody who votes for the Fords and hates urban Toronto would ever even consider voting for the NDP, so it isn't as though they's have anything to lose.
