|Typical WW1 CEF Attestation Papers|
The service files include the two-sided attestation paper (already online as a searchable database on Library and Archives Canada and Ancestry.com), which were completed when the soldier or nurse enlisted, a medical form, training and movement details, and other miscellaneous information.
Each file is different. I have ordered dozens in the past and you never know exactly what will be found in each one or how many pages it might be. A file can range from a half-dozen pages to almost 100.
