Official Stamps
The Cameo definitives, with the exception of the 3 cent denomination, were overprinted "G" for use on federal government "Official" mail. The Cameos were the last stamps to be overprinted. On January 1, 1964, instead of stamps, federal government departments began using envelopes bearing "Canada Postage Paid-Porte Paye". Departments paid the post office a bulk fee based on previous year's stamp usages.
Some government agencies continued using their stocks of official stamps until depleted.
