After two terms she resigned to continue her work campaigning for immigrant settlement and refugee issues, and for equal rights.
[citation needed] Hamilton ran for Toronto city council for a one-year term in 1920, in the first year that women over 21 could vote.
Her platform was a mix of social and practical concerns, including a stronger police force and more library funding.
When she won the race, she became the first woman in Ontario to hold elected office at either the federal, provincial, or municipal level.
"[1] According to the city of Toronto, she resigned so that she could continue to campaign for immigrant settlement and refugee issues, and for equal rights.
[5] After politics, much of her time went into finding employment for new refugees in Toronto, and she also served on the board of Woman's Century, a magazine.
The Bach Society met in the drawing room, and friend later said that Hamilton "filled the rackety old house with a succession of lame dogs and tame cats; refugee cellists from Austria; Englishmen with a gift of the gab who were down on their luck; unemployed Italian waiters; poverty stricken painters; young clergymen whose faith had been shaken."
She also maintained a summer home at Lorne Park west of Toronto for "indigent artists and musicians" with a dozen "ramshackle" cottages on a large property with pine trees.
