@Ravenbird.  Yes a share of the income tax (or a payroll tax) on any income generated in Toronto, or a share of the sales taxes generated in Toronto would be ideal.  But Toronto is a creature of the province and does not have the legal (constitutional) ability to levy such taxes.  Only the federal and provincial governments can do so and they have said NO every time they were asked to give a portion directly to municipalities.  What you can do legally (constitutionally) in Philadelphia, or New York, for revenue generation you can't do here.
