Thank you, Mr. Chair. Let me thank all the witnesses who were here, as well as the witnesses who testified on behalf of VIA Rail, who are no longer with us. We appreciate the time you have taken to come and provide your evidence to this committee. As I think has been expressed by the chair, we are also very thankful for your indulgence as we have been shuttling back and forth for some of the votes today.
I have two areas that I'd like to cover with you. The first has to do with the potential drafting of a federal legislative framework that would deal with occupational stress injuries, and PTSD as a subset of that. Let me ask you in a very open-ended way what your thoughts are about a legislative framework that would, in essence, recognize a presumption of occupational stress injuries for first responders who work in the types of environments that you are familiar with.
Mr. Stapleton, why don't we start with you?
