Under the two different pieces of legislation that we're talking about, under the transportation of dangerous goods legislation and the railway safety legislation, there are two slightly different mechanisms to achieve much of the same outcomes. The protective direction is also meant to be a temporary requirement that is put into place that has an equivalency to the requirement of regulation and can be enforced by Transport Canada, and that is used when we see something that needs a quick action to respond to a safety issue.
The same thing applies to an emergency directive under the Railway Safety Act. They have slightly different mechanics, slightly different specifics around them, but they're very similar.
