Technically, I still have these.
I don't know why the Canadian Government didn't go back to these. Apparently vaccination passports are not a new thing. If the dates in the parenthesis are in fact a publication date, then these are from 1968:
Canadian Document: Q3 2006 (5-68)
These are unused - none of the pages are filled in. They contain pages for the biggies: yellow fever, Smallpox, Cholera... and the last page is dedicated to vaccinations they hadn't made up yet.
