Renée Martel, Hank Snow, k.d. lang and Shania Twain are also recognized in the collection, which salutes Canada's contribution to county music history and became available Thursday.
The five stamps come in a number of sets, including booklets of 10 domestic stamps for $8.50.
Hunter, now 77, first played guitar on a London, Ont., stage at age nine and is best known for his country music variety series The Tommy Hunter Show, which ran for 27 years on CBC-TV starting in 1965.
Hunter's farewell tour in 2012 gave fans an opportunity to enjoy songs such as I'll Fly Away, Daisy A Day and Travellin' Man for a final time.
Hunter is in London, Ont., on Thursday morning, along with Canada Post representatives, for a special stamps unveiling ceremony, and CBC News is there.
