Commuters faced significant delays Monday morning due to a switch problem on Line 6 Finch West that lasted several hours.
The disruption began around 5:30 a.m., when the TTC first reported that trains were not operating between Finch West and Humber College stations due to a switch problem.
Service resumed just before 8:30 a.m.
Metrolinx, which operates the Finch West LRT infrastructure, advised the TTC that maintenance crews were on site to diagnose and repair the switch. The cause of the malfunction remains unknown.
To keep riders moving, the TTC deployed 27 shuttle buses to cover the entire line.
