The following are Canadian overprinted official stamps. In 1949, "O.H.M.S" was printed on stamps for use by government offices. "O.H.M.S." was only used for one year and then subsequently replaced by the "G" overprint.
The following images are all of the "O.H.M.S." stamps that were issued with the exception of O9 which I am still trying to obtain.
