There is no way York Region can afford the whole cost of subway north of Steeles.
For TYSSE, they contributed 1/3 of the cost north of Steeles, other 2/3 coming from the province and from the feds. And that was before McGunty decided to start covering municipal 1/3 of the transit capital costs.
So at most, York Region will contribute 1/3 of the Yonge North cost north of Steeles. Or maybe nothing.
Same for TC. I realize that it's the 1/3 funding split, my point was simply that extending the subway north of Steeles will not capitally cost Toronto anything. And that's what we're worried about: the cost to Toronto's capital budget.
