When they're on their own track, obviously, there will be no jurisdiction from Transport Canada; it will be only while they're running on CP or CN.
Presently, we have only the authority to monitor compliance with those railways. For any railways, whether you're talking about urban transit authorities or provincially regulated short lines, we only have an authority while they're running on federal track. But we only have authority to monitor; we don't have any authority to take any enforcement. So when something goes wrong, we have to impose the enforcement measure on the host railway. Most of the time CN and CP then have to deal with the provincial authority to get the problem resolved.
