It's effectively the same plan that was in place when Doug Ford Sr. was an MPP (Sheppard to SCC). Of course, we also know that conservatives at that time weren't thrilled with the plan (as demonstrated by it being underfunded).
Interesting part is between the added SSE stations at the curve back west, it also delays SSE significantly. Significantly enough that there will be only minimal funding required by Ford for Scarborough during his entire first term because there will not be a construction contract tendered.
Ford's 2022 election campaign will also be about building a subway in Scarborough. It'll be interesting to see how many times Scarborough elects a Ford based on that promise.
