Career
She was the first woman ever to serve as Barrie"s mayor, and one of the earliest women elected as a mayor in all of Ontario. A grandmother and widow, Hamilton served for three years as an alderman on the town council and was active in the local chapter of the Progressive Conservative Party of Canada before being elected mayor in the 1950 municipal election. She also served on the board of the Association of Ontario Mayors and Reeves and the Ontario Hydro Advisory Council.
During the 1952 municipal election, Hamilton became engaged in a public dispute with city clerk and treasurer L. R. Barrand, who tendered his resignation from the city after opposing her plan to separate his position into two distinct job titles to be held by two different people.
Council refused to accept Barrand"s resignation, or Hamilton"s plan. The dispute led councillor James West. Hart to register in the mayoral election against Hamilton, who until that point had been running unopposed.
Hart defeated Hamilton in the election. Hamilton was later appointed as head of Simcoe County"s juvenile and family courts.
She had not previously worked as a lawyer, but was chosen for the position because of her past work in public service and social welfare.
At a provincial conference of the Association of Juvenile and Family Court Judges of Ontario in 1965, she stated in a speech that having been mothers of children gave women a unique advantage in family and juvenile judgeships. She died on December 27, 1990 at the Riverdale Hospital in Toronto.
