Unfortunately the multibillion dollar Canada+Line was designed to have very short stations. Much shorter than any underground stations in Edmonton & Seattle, especially Montreal & Toronto. Planning & building proper big city size infrastructure in BC has mostly been difficult through the years. There has been a multigenerational mindset & agenda to hold BC back.

How could such a backwater BC agenda be so powerful since the 1800s? Well, if you can't build a wall around BC or generate a Star Trek like force field around Greater Vancouver, you can at least continually demonstrate a reluctance to build proper size infrastructure.

BC has had such a slow growth agenda for several decades. Thus, by symbolically building inadequate infrastructure, it is hope that frustrated people will go elsewhere, or don't even show up. WTH? Fortunately, this agenda hasn't taken over Edmonton & Calgary or Seattle WA & Perth WA.
