The TTC says subway service has resumed between Union and St. George stations on Line 1 Yonge-University after it was halted for about an hour during the heart of the evening rush due to a fire.

The fire call went out to Toronto Fire at around 5:36 p.m.

At around 6:40 p.m. the TTC posted that full service has resumed.

It’s not clear where exactly the fire broke out at this point, or what caused it.
