The sad part is there are all sorts of ways this could be done correctly. There are arguments to be made for regionalism and uploading and expansion of the subway network, as well as our transit network at a general level. The Liberals made mistakes and left a lot of unfinished business BUT also laid some substantial groundwork for anyone sincerely interested in taking things to the proverbial next level.
Though time will ultimately tell, everything we're hearing suggests this will be done in the stupidest possible way. Talking about extending the subway into York - which so far entails an entirely sensible, short line through an urbanized corridor that connects to an established transit node and designated growth centre - in the same breath about talking about an obviously-nutty line to Pickering shows how overly broad and incoherent this will be. Not even "Pickering," - they just talk about "Durham," "Peel," and "York" - each of which has substantial rural portions - because they have no clue what might actually make sense; they just know where the votes are.
This won't be about improving connectivity and intensification; it will just be about "suburbs deserve subways!"
I keep hoping for the best - because I strongly believe we've hit the limits of what can be achieved with our current funding and governance models (the CodeRed report certainly covers the former very well, as well as much of the latter) but there is no reason to believe what the PCs are talking about will actually address any of it. And that will just fuel the already simmering Toronto-based fears of their interest (both with with the DRL specifically, and Toronto's local needs, generally) being diluted and thereby poison the well for what what really needs to be done.
