Thank you for the question, Mr. Barsalou‑Duval.
Depending on the situation, in the past we have considered using buses when a train is cancelled and/or it's en route and it's disabled. In those particular cases, it's obviously dependent on service. Can we actually source a bus? In this particular case you're referring to, we could not have done that. In this case very specifically, on the 23rd, roads were not accessible, so busing was not an option.
On anything to do with any cancellations from the 24th to the 26th, we did have a conversation related to whether or not busing could become an option for the trains that were cancelled, because we understood from a passenger perspective that they wanted to get to their families on the holidays.
