I can never understand this desire to "get ahead of the curve" with subways, especially when it's at the expense of existing dense areas that have needed subway lines for decades. To take your thinking to its logical conclusion, the Yonge and Bloor lines should never have been built, and the DRL should never be built despite the fact that its ridership would rival the Bloor line from day 1. Instead, we should be building subway lines to Oshawa and Newmarket to "get ahead of the curve".It's high time subway construction got ahead of the curve. I can never understand why people complain about building subways to 'nowehere'. I say subways should always be built to nowhere.
Subways should be built, first and foremost in the dense environments that need them, not nowheresville suburbia. Let regional rail worry about the outer suburbs.
