You can literally see the location of the LRT - shifted to the north - in the plans for the Line 2 extension.Seems like ML made all the plans with Scarborough subway and GO rail without an extension in mind. TO came along and wanted this LRT that they have no interest to be part of the Crosstown. ML and the PCs don't seem to like it and ignored it. So there we are.
Surely the elevated piece would be on the order of hundreds of millions, not billions. There's also savings on not having to build a new station.Finance.
According to the preliminary estimates of the new plan, it's about $2billion cheaper than the original plan that would tie-in with the Crosstown. Elevating the line over the Stouffville Line would eat up most of those savings.
