Now, now lets be honest for a moment. The suburbs have not voted down any Downtown subway (yet), while the opposite cant be said. And I completely agree there is a need for extensive relief to be built, but that is along with suburban growth with priority for both needs. How can that be achieved?
Downtown voters might need to start voting in other parties in the Province and maybe Federal level to see any urgent action. Even if its just for a one term timeout to get their attention. Otherwise their is no reason for the Conservatives to buy them off when their vote is stubbornly static and no reason for the Left parties to do anything more than show up, there is simply no need to woo large blocks of Downtown voters as the Left parties just have to show up. Just an idea that might actually work because having local councillors piss off other areas of the neglected City wont help solve this problem any way. IMO its the only solution to achieve the necessary attention or action you seem to blame the suburbs for?
