TTC Line 1 trains are moving slower than usual between King and TMU stations as excavation work for the Ontario Line deepens underneath Queen Street West and Yonge Street. The reduced speed zone is noticeable as trains depart Queen Station, with the TTC saying it needs the slower speeds to monitor potential impact on track infrastructure.

The TTC says reduced speeds are adding no more than a minute to trips, but commuters report longer waits. "It's taking a while for me to get to Union. It makes me not want to go to TMU at all because of these slow TTCs and trains," one rider said. Another said the slowdown has made them miss trains and classes.

The excavation is connecting the new Ontario Line to the existing TTC Line 1. Ontario's government says tunneling has already begun across the full length of the Ontario Line, which will run over 15 kilometres with 15 stations and more than 40 transit connections from Exhibition Place to Eglinton Crosstown LRT at Don Mills Road. Metrolinx says the line will put more than 200,000 people within walking distance of a subway station.

Construction of the Ontario Line began in December 2021 and is expected to be complete by 2031 according to Metrolinx. The TTC has not said when the reduced speed zone will be lifted.
