The tender says "The plan will assume that the incremental tax revenues arising from the construction of the proposed Sheppard subway extension corridors as well as from the construction of the Eglinton-Scarborough Crosstown line can be applied towards funding the capital costs of the Sheppard subway extension projects. "
This is new, isn't it? In other words, the Fords want to pledge property tax revenue from all over the city to pay for Sheppard. The notion that public money would not go into this white elephant is simply a lie.
This actually does kind of make sense. You roll the property value increases into the funding for the next transit line. Assuming that every line you build generates a property value increase, you can continually roll increases from the previous project into paying for the next one.
This happens all across the development industry. The developer will place their most profitable units in Phase 1, and when those sell, they use some of the profits in order to help finanace Phase 2. Profits from Phase 2 help finance Phase 3, etc etc etc.
