You're actually looking at two completely separate datasets. Because the Canadian Armed Forces has their own health care system, they provide health care. They have access to what we would call epidemiological data to look at things like diagnosis, and sometimes you can find mechanisms of injury.
Veterans Affairs, on the other hand, doesn't provide health care. I apologize if anyone from Veterans Affairs is listening, but they're like an insurance company. They provide benefits and programs and they support them, but they deliver some, not all. They're going to have different datasets.
What is key is that there is collaboration to determine what data needs to be collected so that it becomes useful information to create the cause and effect you were talking about. As I said, data might prevent more people from being injured, especially data on women.
