If your relative served in the Canadian forces during the Second World War, (or WWI) the Library and Archives Canada releases official service records for free (an abbreviated package).
It’s fascinating to read them.
For WW1 files, they are all online here for free: WW1 FILES
For WW2 files, you can get files of those who were killed in action, digitized (although sometimes they only have about 60 pages, but not the entire file).
If you don’t find the person’s name, or you want their entire files–which could run one hundred pages sometimes, (and it is worth it)– then you have to apply for free for the whole file.
There is a form to fill out online.
Some noteworthy Second World War service files are already digitized and online, including some belonging to deceased Jewish personnel like Samuel Moses Hurwitz.
If you would be happy with just an abbreviated version of WWII files, Ancestry.ca has partial files of the 44,000 personnel who were killed in WWll or died shortly after, of injuries. You can pay to subscribe, or ask your public library if they have it, for free. For example, Richmond Hill’s Public Library offers this service.
