GO Train Delays Today: Signal Issue at Union Station Toronto Disrupts GO Transit and UP Express

Toronto, Canada — Thousands of commuters across the Greater Toronto Area faced significant disruption this morning as GO Train delays were reported following a signal issue at Union Station Toronto, impacting multiple GO Transit corridors and the UP Express.

What Caused the GO Train Delays Today?

According to GO Transit officials, a signal malfunction near Union Station triggered widespread delays during peak travel hours. The issue affected inbound and outbound train movements, forcing trains to operate at reduced speeds and causing congestion across the network.

Union Station Toronto, one of Canada’s busiest transit hubs, handles hundreds of GO Trains daily. Even minor signal disruptions can cascade across the system, leading to prolonged delays on multiple lines.

The following GO Transit corridors experienced delays of up to 30–60 minutes:

While UP Express trains continued running, service frequency was reduced as crews coordinated movements through the affected signal zone near Union Station.

Was There a GO Train Derailment?
