That's why it can be hard to compare 1:1 transit projects in Canada with other places. From what I've seen, we tend to include much more infrastructure spending such as sewers, roads, utilities etc. that other places don't.
This is a good thing in a lot of ways, but unfortunately results in a high looking total cost, which hurts the political viability of projects. Projects should really been broken down into direct transit investment, and infrastructure improvements so people actually understand where the money is going.
