Except Bobby GTA residents directly pay for the highways running through their municipalities with municipal fees and taxes. Also GTA residents contribute by far the most to provincial (and federal) income,sales and corporate taxes. Thus, even the transfers municipalities receive from the province are heavily subsidised by GTA residents.

In fact it has  been estimated that for every dollar in tax paid by a GTA resident, only 10c stays within the GTA, the rest flows out to the rest of the province and country. GTA pays for Ontario and is a substantial contributor to the rest of Canada!
