OC Transpo's O-Train service is back up and fully running after a number of platforms on the Confederation Line's east end were shut down.
The closure of the eastbound platform at St-Laurent Station was announced around 1:30 p.m., Tuesday.
At that time, the city's transit body also announced O-Train Line 1 not operating between Cyrville and Blair Stations.
About ten minutes later, OC Transpo tweeted that the westbound platform at Cyrville Station had been closed.
Around 2:15 p.m., OC Transpo announced full service had resumed with delays on O-Train Line 1.
There was never any official word on what the problem was, but riders did report OC Transpo operators having to close O-Train doors manually.
