The TTC published an estimated escalated cost of the LRT, and it was something like $2.5 billion. Supporters of the LRT called it bullcrap of course, refusing to believe those numbers. Apparently the LRT is immune from cost changes but the subway is possible to see infinite increases into the trillions.
TTC CEO said that the reason for the high LRT cost estimates was its later contruction start date. They assumed that any contruction of the Scarborough LRT could not begin until contruction of the Eglinton Line was complete, in September 2021.
When questioned about the rational for this assumption, Byford admitted that the construction start date estimate could have been inaccurate, and that contruction of the Scarborough LRT could start much sooner than September 2021, if they started building the north end of the line immediately. The only part of the line that needed to start contruction after Sept 2021 was the part connecting to Kennedy Station. So until the TTC releases revised estimates accounting for that, we don't know what the LRT would've cost.
