Heat wave leads to significant delays, cancellations on GO Transit network Posted July 14, 2026 7:58 pm. Significant delays and even some cancellations left GO Transit riders waiting to get home Tuesday evening. Photos from Union Station in Toronto show crowds of people standing shoulder-to-shoulder watching information screens, waiting to see when their train leaves.

Metrolinx says the heat wave means trains have to run slower and that service has been modified due to track conditions. Delays up to an hour were reported on some of the lines, while some trains were canceled altogether.
