Update, 3 p.m: The TTC has announced that snow continues to buid up under the power rail on the Scarborough RT so service will not resume during the afternoon rush hour and may not run this evening. Shuttle buses are running between Kennedy and McCowan Stations.
Switch problems that have been affecting the Scarborough RT have finally shut down service on the line. Shuttle buses are rushing to compensate. We will keep you posted as the situation develops.
