Thank you for the question, MP Boulerice.
During the night of the 23rd and into the 24th, I would say there was regular/constant communication by way of telephone and by way of text message between operational personnel attempting updates.
When we move forward into the events following the derailment, the timeline becomes a little different as CN assesses the derailment and assesses its ability to clear the track and its timeline. In that case, we're now in contact, I'll say, every couple of hours as the situation changes in the field.
Through that process, we continued to update our planned service. We didn't want to cancel service prematurely, but we wanted to ensure that we communicated with passengers before they left for the station or before they began travel that would take them to a Via Rail station.
