The number is about 30, sir.
I was the brigade surgeon in Petawawa in the late 1990s, the senior physician on that base, and we had three mental health care providers then. We've tripled that number to nine, and the mental health care project seeks to triple it again, to roughly 31.
The reason there is such a large number in Edmonton, and some other bases you've mentioned, is that those bases host operational traumas at stress support centres. We have five of these centres, a network of five across the country. When those centres were set up in the late 1990s, the decision was made that the regional centre for Ontario would be in Ottawa, because it serves not only Ottawa, but Kingston, Trenton, Toronto, Borden, and Petawawa.
