You can see this causes concerns for all of my colleagues, including me.
You also said, in your evidence, that there are plans to handle an event. I understand that your department has worked hard to limit the number of occurrences, but really, with these types of incidents, as Lac-Mégantic demonstrated, it only takes one incident to kill 47 people and level 30 buildings.
Is it your evidence—did I understand it correctly—that the plans to deal with such an event aren't currently disclosed to first responders?
