On May 17, the entirety of the blue line was shut down for over 8 hours. That same week service on the green line was interrupted twice. The first closure was due to water infiltration, while the second closure was shut down due to the presence of smoke.\nThe STM has just announced that they have currently closed the Papineau metro station. They state that they are doing temporary construction work which has closed the station. This closure was unplanned.\nEarlier on Friday, the STM published the Tweet below:\n[Fermeture de la station Papineau] 🚇⚠️ Des travaux temporaires au niveau de la mezzanine entraînent la fermeture de la station Papineau.
