If the entire plan to reinvigorate STC is based on getting a subway station then they're in trouble.
Subway stops have not turned the areas surrounding Warden and Kennedy stations into dense urban centres in the years they've been built.
Sheppard got an entire subway line, and change has been slow to nearly non-existent in stretches.
Scarborough, for many decades, has had 2 subway stops and a direct line connecting STC to Kennedy. This was there long before Scarborough became part of Toronto. This is a benefit no other suburb had, yet an STC boom didn't really happen.
Everyone wants change - Scarborough residents are not unique in that regard. It's one thing to want change, it's another to spend billions of dollars on something that makes no sense just for the sake of it.
The general rule of thumb is that you don't build a subway until there is density to support it - The first subway line in the city wasn't built until the streetcar line was maxed out.
As we've seen, a 'build it and they will come' approach doesn't really work. We have examples here in Toronto, but I guess we're not too keen on learning from the past.
