I have recently researched this archives business for the members of another forum and I can tell you directly from the staff at Library & Archives Canada that the standard free "genie package" (short for genealogy) includes only those files that relate to a person's sign-up, training, promotions and postings, etc.
Sometimes a burial card and other documents are included that give more personal details but if it contains anything like an accident/incident report or other personal effects, you won't get it without paying the copying charges. They do their best to send what they can, I was told, but they limit it to a couple of dozen pages at most.
I have several and they were quite detailed for what I needed but I also plan to visit Ottawa to see the whole file on several of my subjects.
