Technically, it is still possible to select the third option: above-ground, south of the road alignment between the Laird and Don Mills portal. It will cost some extra money (likely, new bridge over West Don). But other than that, all wins: higher frequency will be feasible; Leslie stop will be preserved for whoever wants it; investment in the launch shaft construction will not be wasted.
Unfortunately, I doubt that Metrolinx will reopen the issue, due to political and administrative hurdles. They will stick to the current plan, which is good in general but suboptimal in certain details.
It may even be less expensive to build the south side alignment - because the pocket and cross-over tracks could be moved from Laird in the middle of road to the south side near Don Mills.
However, it has already been awarded so it will not be changed.
