did you miss the City of Toronto act that specifically gave Toronto a variety of revenue tools that no other municipality has.  Sure the act doesn't allow for Tolls but it does allow for Land Transfer, Vehicle Registration Fees and a host of others not to mention they could raise property taxes.  But no the city want's to spend billions of their own money for a one stop Subway to no where instead of a full paid LRT in Scarborough.

Also while not currently the municipalities in the GTA did send part of our property tax dollars to Toronto to help with their costs - in this case Social assistance and social housing in the recent past.

Regarding transit - we also help there 75 % of the operating costs are paid by Users so if we GTAers us it we paid.  Then there is the money you receive from the Feds and Province for new projects.
