If Toronto really needs more money it can raise its property tax rate to the same level as the 905.
This cheap identify politics of Tory (sounds more and more like Miller) is nothing more than a sleazy defection and part of the blame game and is utterly disgusting.
Ontario and Canada pour billions into Toronto's coffers each year and that money comes from all Ontarians, including the 905, and from all of Canada.  In fact, the 905, with higher median incomes than Toronto pay more than Toronto residents do in Ontario and federal income taxes.
But the true nuttiness of Tory's proposal is the millions Toronto and Ontario spend on promoting Toronto, including the hundreds of millions on events such as the Pan Am games, to entice people to come to Toronto  and now Tory wants a special road tax to discourage people from the 905 from coming to Toronto.
