My superficial answer would be yes, absolutely. Certainly each individual is screened.
You can discuss the degree of rigour in that screening process with the Canadian Forces Surgeon General.
We go through quite a process to make sure they are healthy, mentally and otherwise, before deployment and on their way back. We also have a decompression process—third-location decompression, which you may have heard about—that has proven very effective and is very much appreciated by the soldiers. This was the initial feedback for the first wave who came back from this.
The decompression is not exclusively about blowing off steam, although I suppose that's a part of it. It's about connecting with health care professionals and others to help them prepare for and adjust to the world back in Canada.
