Scarborough Subway Extension Tunnelling officially began on the 7.8-km extension in January 2023. The tunnel boring machine (TBM), which arrived from Germany in late 2022 and has been named Diggy Stardust, is currently traveling on average 12 metres a day south from the launch shaft at Sheppard Avenue East and McCowan Road towards Eglinton Avenue East and Midland Avenue. It will dig about 6.9 kilometres of the 7.8 km line. Ground broke at this site in June 2021. (Metrolinx photo)

The subway extension is estimated to cost more than $10.2 billion, nearly double the initial estimate ($5.5 billion) announced by the province six years ago, according to figures from Metrolinx leased in late June.
