Flooding could influence the flow of traffic to Rogers Centre for Friday night's Blue Jays game against the Red Sox.
Excess water at Union Station has forced the closing of the subway service between Bloor and Osgoode stations for the afternoon rush hour period, according to the Toronto Transit Commission.
According to reports, 104 shuttle buses are operating in both directions between Bloor and Osgoode and are stopping at every station aside from Union Station, which is closed. The PATH underground system has also been shut down at the Union GO Terminal.
GO train and bus services continue to operate according to schedule, though the doorways from Bay St. into the concourse have been closed.
The Blue Jays begin a three-game series with Boston at 7:07 p.m. ET.
