There are two things. The first one is, and you touched on it, accountability. They may be accountable to the province or other governing bodies, but while they're operating on federal track, as I explained on Tuesday, we have the authority to measure compliance, but no authority to impose enforcement action when they're non-compliant. Therefore, we have to turn to the host railway and impose a corrective measure on the host railway, which then has to go and get the commuter operator to fix the issues they have to deal with.
The second thing is that I believe many of those commuter operators do already have in place what we're looking for. For instance, West Coast Express has a safety management system, which may be the tool that we will require to give an ROC. They already have one; they've asked us to audit their safety management system. However, we don't have the jurisdiction to do it.
