Except the costs for stage 1 and 2 per kilometre are the second lowest of all Canadian transit projects, adjust for inflation (REM is 1st, but they got more ROW for free). We could have built a heavy rail system, but it's not like anything is irredeemable with it as it is. The costs of running R1 service are a drop in the bucket when you look at what MTL and Toronto are paying for their new builds vs what we pay for ours.
You can call it unreliable. You can call it dinky. But good luck trying to call it expensive.
