Finding More Details on a Canadian WW1 Military Ancestor

John asked about Canadian Military records:

I'm looking for information on how to determine where my Great Uncle  fought in the 1st World War.  His Attestation papers for Canadian Over-seas Expeditionary Force state that he was part of the 1st Battallion C.O.B., C.E.F.for 8 weeks then transferred to R.C.R. for 4 months as listed under "former  Naval or Military service". I have his regimental number .  Where do I go from here to get more information on where he fought and what he did?  Do these records exist?  Any help would be greatly appreciated.

ASK OLIVE TREE RESPONSE: Hi Jim -  what you have is just a small part of the whole file. The attestation papers are only the front and back of the man's signup sheet.

You want to order the full record from LAC (Library & Archives Canada). Just go to
the site and read how to order them, or go to The Canadian Military Heritage Project and click on FIND YOUR MILITARY ANCESTOR

The full file will give his movements on specific dates and often much more. There is no consistency though. You may get one page of information or you may get dozens. It depends what has survived.
