they have
'do not remove'
'ne pas enlever'
in the picture...as do the real ones...I zoomed in, and compared them to the original backing and they have the correct wording
http://en.wikipedia.org/wiki/Dog_tag_(identifier)#Canada
Canadian Forces identity discs (abbreviated "I discs") are designed to be broken in two in the case of fatality; the lower half is returned to National Defence Headquarters with the member's personal documents, while the upper half remains on the body. The tags contain the following information: [6]
* Upper half:
o Service Number (SN)
o Initials and surname
o Religion and blood group with RH factor
o The legend "CDN FORCES CDN" (or for foreign nationals, the name of the country the individual represents)
o The text "DO NOT REMOVE / NE PAS ENLEVER" on the reverse
* Lower half: identical, except it does not contain the blood type, and the reverse is blank.
Before the Service Number was introduced in the 1990s, military personnel were identified on the I discs (as well as other documents) by their Social Insurance Number.

but they still don't look like real tags to me, but what do I know, I've never seen real canadian dog tags, just pictures
