With the Scarborough RT nearing the end of its life, the Transit City plan proposed to convert the line to LRT, and extend it north to Sheppard Avenue, to interface with the Sheppard East LRT.

• The total length of the new line would be 11.4 km, with 9 stations (compared with 6 stations on the existing Scarborough RT.)
• While originally planned to be completed prior to the PanAm games in 2016, current plans call for construction to start after the games with the line to open in 2020.
