If you use the TTC to get around, how would you feel about paying more based on how far you're travelling?

That's one idea being tossed around in a 116-page report from the Residential and Civil Construction Alliance of Ontario, on how to expand public transit in the Greater Toronto & Hamilton Area.

The report titled "Financing Roads and Public Transit in the Greater Toronto and Hamilton Area",  says new sources of revenue are needed to operate and maintain planned projects that Metrolinx has set aside an estimated $50 billion worth of capital for.

The report written by Harry Kitchen, Professor in the Department of Economics at Trent University and Robin Lindsey, Professor in the Sauder School of Business at University of British Columbia, says there could be economic impacts if traffic congestion isn't dealt with.

"The GTHA is Canada's economic powerhouse but this position will slip if traffic congestion is not properly managed through better pricing structures. Unless significant revenues are devoted to infrastructure improvements, it will negatively impact the potential of this region," says Kitchen.

The report also suggests road tolls be introduced on the 400 series highways to raise $40-billion needed to expand public tansit.

The report also addreses the issue of parking downtown, and what would happen if there were fewer spaces at premium prices. It recommends that restructured parking fees be based on occupancy rates, including escalating hourly rates rather than maximum charges.

The group is also calling on the province to look at commercial parking taxes, vehicle taxes and regional fuel or sales taxes.
