How much would it cost to realistically finish the Sheppard line Downview to SCC? I'd think about $1B to do the western leg, and $2.5B to do the eastern leg. I think the main driver in subway construction costs is the huge stations that the TTC builds. If they keep station costs down to $50M each then we could actually finish what we started using the funds McGuinty gave TTC for SELRT, Finch LRT. I'd be ok sacrificing the Finch LRT and SELRT in favour of having a completed Sheppard line as I think it'll be a better network to have a completed E-W subway line above the 401 and reduces the vehicle type transfers on Sheppard.
