To repeat something I said on another thread, early last year when construction fences went up half a block north of the current station, they hung up a notice on the fence showing a map of the porposed site, and the Ontario Line portion of the station was going to be further up the street, closer to Wynford. Before that, the Ontario line station was to have been on the opposite southwest corner, where the secondary entrance is, but that was before they built the new office building on the northwest corner, which made that plan impossible. Then later last year, they took down the signs and put up new ones to show the future station closer to Eglinton, but still not right at the intersection, and the overhead tracks were to cut across the intersection diagonally, which seemed like a crazy idea. Then they took down those signs, and did not put up any new ones, and I haven't seen any pictures or maps since then, but I did hear that the plan to put the tracks diagonally across the intersection had changed, and now the tracks are to cross Don Mills south of the intersection.
So I've been waiting to see what the new plan is, and I'm surprised that the station will now be right at the corner. And it's huge! My question was always, is the new building going to touch the existing bus bay building, and if so, are they going to have to lop off the front of the existing building. Looking at the floor plan in the link provided, it appears that the existing building is going to run right through the new building, so yes, I think they will have to tear down a significant part of the bus bay entrance to join the 2 buildings together. I notice the floor plan still shows the new mini intersection where buses will turn at Don Mills and into the station, but that is missing altogether on the artist rendering pictures above.
As for where the tracks are going to cross Don Mills, the pictures seem to still be showing them crossing the intersection diagonally, but it's hard to be certain, and the pictures may not match the current plan.
So while these plans and pictures are giving us a lot of information, we're still not seeing the road plan, nor a floor plan for the station's upper level, nor a road map for what will happen north of the station. I know it's been said the elevated tracks will continue all the way to the railroad tracks further north, which means another elevated crossing over Wynford, but it's hard to tell what's been proposed in the past vs. what's being planned now. Plans seem to have changed multiple times recently.
