Newfoundland and Labrador Military Records
The Provincial Archives of Newfoundland and Labrador (P.A.N.L.) has no militia files for Newfoundland. It has some records of British troops in Newfoundland prior to 1870 and of Newfoundland servicemen who served in World War I and World War II.
However this military history bibliography from Memorial University may be useful http://shaggy-vm.library.mun.ca/qeii/cns/Newfoundland%20Military%20History%20Bibliography.pdf
