Toronto's Bloor-Yonge subway station has reopened after a water main broke flooded the platform and forced a closure.

The TTC issued two alerts Saturday morning, telling customers there is no train service out of the station along the Yonge-University-Spadina line. The break is also affecting service on the Bloor-Danforth line.

The station opened its doors around 8 p.m. on Saturday evening.

The TTC said the water was leaking and crews were been brought in to remove some ceiling tiles and tarps were put up to contain the water.

The problem came a day after extreme cold knocked about 50 streetcars out of commission. The TTC said moisture building up in the pneumatic air lines that provide braking and door operation was freezing.
