TTC Service

Regular subway service has resumed at Union, Lawrence West and Yorkdale stations. Meanwhile, trains are not stopping at Glencairn Station due to a power failure. The TTC says Union, St. Patrick and Pape stations are not accessible due to elevators and escalators being out of service.

On Line 2, service has resumed between Islington and Jane Stations. Earlier, there were no trains running between the two stations due to a power failure.

GO Service

The GO Train has also seen significant delays due to weather-related track conditions. Some trips on a number of lines have been modified as a result.

“Extremely heavy rainfall has slowed the ability of the ground to absorb the water, which is causing areas of flooding, which is impacting service across our network,” an alert reads on GO Transit’s website. “Delays, modifications, and cancellations are expected for your evening commute. We are working hard to keep you moving.”

UP Express trains has resumed operations at all stations, including Union. However, Metrolinx warns there could be significant delays as it works to resume our regular schedule.

Toronto airports, flights

While the closure of Convair Drive has made it difficult to approach Toronto Pearson Airport by car, flights to and from the airport have not been impacted. Billy Bishop Airport has warned passengers that some flights could be delayed, and encouraged passengers to confirm flight status with their airline. Additionally, the pedestrian tunnel at Billy Bishop is closed due to flooding. All passengers and staff will be redirected to the ferry.
