AMT mostly operates on CN and CP tracks, except for in the north, from the crossing in Blainville to Saint-Antoine or Saint-Jérôme. That is their property. It belongs to them. So, we don't meddle with it. We don't concern ourselves with that section.
When they go south, toward Montreal, and get to the Blainville crossing on Seigneurie Boulevard, they are operating on railway tracks that belong to Canadian Pacific.
