Certainly.
As we mentioned, exposure is complicated. I heard what the Brigadier-General from the CAF said in the first hour. I think she talked about cigarette smoke. Exposure to second-hand smoke is different from smoking for 25 years.
We're always striving to, number one, increase our knowledge and increase our scientific evidence base. Within Veterans Affairs, as I mentioned, we do have a team of physicians who work to establish what we call internally entitlement eligibility guidelines for a whole host of conditions. Specifically on exposures, we have a document, or a database, if you will, of the information that CAF has in their records around exposure sites and where certain chemicals may have been used. We also have information included in that from partners, from other countries where we've collaborated and where we've had joint missions and joint operations. Perhaps it was an American lead, we supported that and they have information. We have that at our disposal.
The other important piece we have is research on causality and the effect of exposure. It's really important to distinguish. On the one hand, we need to understand that an exposure happened, but we also have to understand the effect of the exposure. That research could come from many, many different sources. We work with academia in Canada. We rely on the work of other partners as well, such as Five Eyes countries.
That research, that information, is ever evolving and ever improving. I think that's the point. We've set up a process or a framework internally in the department to continually learn and to continually grow in our understanding so that as the knowledge and research evolves, we'll be more responsive and able to provide veterans with the benefits they're entitled to.
