Subway service has resumed between Lawrence West and St. George stations after radio problems caused a significant delay during Friday's morning commute.

For about an hour, there was no service on the TTC's Line 1 (Yonge-University-Spadina line) between Lawrence West and St. George Stations.

The TTC dispatched about 70 shuttle buses along the route, but the lack of subway service caused long delays for commuters heading into downtown. Subway service resumed just after 9:20 a.m. but the delay caused a significant backlog.
