GO Transit riders faced a second straight morning of disruptions due to a signal issue that affected the Lakeshore East line — a problem that first triggered widespread delays during Wednesday’s rush hour.
As of 1:45 p.m. on Thursday, GO Transit said that “the ongoing signal issue on the Lakeshore East line has now been resolved and regular service has resumed.”
According to the GO Transit website, trains on the Lakeshore East line were experiencing delays of 20 to 30 minutes.
Metrolinx suggests that riders monitor “On the GO Alerts” (text and email alerts) and check GO Transit’s website for real‑time updates when delays happen.
Metrolinx has not yet provided a detailed explanation of the underlying signal failure.
On Wednesday, the issue caused delays not only on Lakeshore East but also on trains passing through the same junctions, including the Stouffville and Richmond Hill lines.
