The planned signalling upgrades were upended with the development of Metrolinx’s GO Expansion project.
Metrolinx is writing off $504 million it spent on a signalling system around Union Station that it has largely scrapped, according to its own annual report.
The provincial transit agency had launched the signalling renewal project in 2013, but that work was sidelined after it launched its plans for GO Expansion.
A GO train alert advised commuters to allow extra time for their commutes.
Funding constraints mean progress on the long-touted project stalled in February.
The delays come less than a week after another signal issue disrupted service on the Lakeshore East line.
