High Tech is being pushed by Richmond Hill and will be built because its ultra cheap, and because the tracks will be there regardless due to the MSF. High Tech basically adds nothing to the overall cost and at worst is a low hanging fruit station. Its completely harmless, don't bring that into this conversation.
Yes, and people keep missing the forest for the trees: this is a suburban line that people in Toronto seem to think is ending in a field. More accurately, it's ending in an LCBO parking lot
The key to these stations is how much density they are unlocking (and therefore, ridership). High Tech, even underground, is a huge net gain by those standards. At grade, it's a no-brainer and anyone who opposes it, because of the station spacing, doesn't understand the actual logic underpinning the extension.
The Bridge Station also unlocks massive density (and, not incidentally, revenue for the province). This was also true at the Langstaff Station location but it's still true at Bridge, even in its between-the-highways location. Before Places to Grow and the subway plans, those lands were useless industrial lands where they were going to put a Viva bus garage. Now they are expected to house like 25,000 people. Anyone who wants to see more dense development built around transit (as opposed to "sprawl" etc.) has to see this as a massive net gain. It's a quirk of the site, yes, that it's divided by two highways and a municipal border but, even at 400m spacing, everyone is going to get their money's worth from these 2 stations, I assure you.
Back when the original alignment was being done, they described the 2 final stations as two halves of a whole, each serving different functions. You have to see it that way. Each unlocks density in their respective municipalities and Bridge's other, equally important job, is to provide transit connectivity for "Union Station North."
The only reason Royal Orchard is remotely under consideration is for this same reason: the plan to build up-to-60-storey towers on the plaza site there. But, as myself and many others have pointed out, beyond that single site there is relatively little room for intensification. Combine that with the lack of feeder bus routes and it really is a dog. I mean, I'd expect it to be worse than Bessarion. And if they don't build the station, it'll be impossible for Markham to approve the development at that scale, on that site, so the developers are really just creating a Catch-22. Without their development the station makes zero sense and vice versa. I say, no station and let them build 20-25 storeys and we can all move on.
I agree that Clark makes the most sense of the 3 neighbourhood stations and certainly the data in the IBC suggests this is true as well. It best breaks up the Steeles-7 spacing, it best serves bus routes and it has the best potential for adding density.
Most of the rest of this discussion is trying to keep the conversation going until we get the next round of updated info
