Yes, indeed, I think that's something that would take further study. On its face, it sounds as if that would be very helpful.
Just look at the example, about a month ago, where CN, which manages the rail corridor around Union Station, lost some Internet connectivity, and as a result systems like Metrolinx were not able to deliver along the Lakeshore line for a few hours. This left passengers stranded or waiting. As an example, southwest of that, as far as London, there were impacts just based on that.
I think there is room for regulation in that area.
