One of the things we discovered from listening to the rail industry is that they had not actually done risk assessments, on closing down lines, for example, in anticipation of the 500-fold increase in transportation of petrochemicals or petroleum products.
I've heard you say on several occasions that there are risk assessments done on a regular basis by the industry.
Is that done to please your insurers or to please Transport Canada? How do those risk assessments take place, and will you be doing one if the volume of petrochemicals is going up?
