His tenure in civic politics set a record for longest continual years of service.

[12] The following year, he was successful in having a charge of illegally competing with the Ottawa Electric Railway (OER) withdrawn, as he was suspected of accepting remuneration from passengers in his automobile.

[11] On November 2, 1931, Hamilton announced that he would run for city council in his home Dalhousie Ward in the 1931 Ottawa municipal election.

McVeigh was defeated, after having finished third, just 38 votes behind Hamilton, and was the only alderman who lost his seat in the election.

He became chairman of the Mothers' Allowances again, was a member of the special committee on classification of civic employees.

[25] Ending more speculation that he would run for Board of Control that year, Hamilton ran for re-election again in the 1937 election.

Following the election, Hamilton continued his chairmanship of the Civic Industrial and Publicity Committee until asking to be removed as chair in August 1941.

[38] In 1947, he and Mayor J. E. Stanley Lewis travelled to the Soviet Union to commemorate the 800th anniversary of the founding of Moscow.

[39] In the 1948 election, Hamilton finally topped the poll in Dalhousie Ward, winning 2,261 votes.

[48] He considered running for mayor of Ottawa in the 1954 election, but dropped out in October, stating that the only way he could beat incumbent Charlotte Whitton was in a one on one race.

However, Whitton already faced two credible opponents in David Luther Burgess, a prominent member of the Royal Canadian Legion and former mayor E. A. Bourque,[49] so Hamilton stayed out.

[48] On election day, Hamilton was re-elected, topping the poll in Ward 6, winning 4,021 votes, just 20 more than McAulay.

[50] On October 20, 1956, Hamilton announced he was going to run for the city's Board of Control, council's four member executive branch, in the 1956 election.

With his win, Hamilton would retain his vice presidency of the CCEA which he had held over the previous term.

[56] On election day, he won 28,763 votes, good enough for fourth place, the last spot on the board.

[59] Hamilton was appointed as a member of the Ottawa Transportation Commission on November 3, 1962,[11] resigning from the Board of Control in the process.

[60] Not even two years after his appointment to the OTC, Hamilton was rushed to the Ottawa Civic Hospital on June 7, 1964, where he would have a blood clot removed from his brain.

[11] Hamilton married his first wife, Olive Beatrice Patterson in 1921 at McLeod Street Methodist Church in Ottawa.

Five years after her death, Hamilton re-married in 1945 to Marjorie Valentine Giddings at First United Church.

[63] Hamilton was a founding member of the Ottawa Club of Printing House Craftsmen, and served as president in 1946.

[8] He was a member of the Erskine Presbyterian Church, and the Doric Freemason Lodge,[11] the International Typographical Union, was president of the Dalhousie Municipal Association, was on the executive of the Dalhousie Community Club, Wellington Home and School Club, and the Primrose Athletic Association.
