Thank you for your questions, Mr. Aubin.
I don't have all the details concerning the specific incident in Yamachiche. However, I can assure you that the Canadian Coast Guard's marine communications and traffic services are working with the Corporation of Mid St. Lawrence Pilots and Transport Canada. We're constantly working on the use of the water column when vessels pass through. When we look at a marine corridor, we take into account all the conditions. These conditions include the ice cover, the lack of an ice cover, flooding, lower water levels, and so on. The safe passage speed obviously depends on the draft and the type of vessel. We really work together.
In the case that you mentioned, I believe that the water level was already extremely high, and deep draft vessels needed to pass through. We had to work with the Corporation of Mid St. Lawrence Pilots and with the Laurentian Pilotage Authority.
There may be damage sometimes, but the Canadian Coast Guard works very closely with all its partners to determine the best way to use the water column.
I can provide more details on this specific incident.
