Donald Thomas Hardy Paine was a urologist and general surgeon in North Bay, Ontario, Canada. He was born in London, England, on 20 July 1921, the son of Stanley William Thomas Paine, an engineer, and Rosina May Paine née Baker.

He was a house surgeon in Eastbourne, Croydon and Tunbridge Wells, and then a resident surgical officer at Victoria Hospital, Blackpool, from 1945 to 1948. He was subsequently a resident surgical officer (surgical registrar) at Blackburn Royal Hospital until 1950. From 1950 to 1952 he was a surgical specialist to the British Army of the Rhine.

He led the establishment of the northern Ontario kidney dialysis unit at Civic Hospital. He was director of the Ontario Medical Association from 1974 to 1979. In 1979 Paine, again fleeing this time the impending socialisation of medicine in Canada, he moved to the United States, to South Carolina near Myrtle Beach, where he continued as a urologist until his retirement in 1988.
