She was first elected to Victoria City Council in a by-election in November 2010, following the resignation of Sonya Chandler.[2] The by-election took place on the same day as the city's referendum on the Johnson Street Bridge replacement project, which passed with 60 per cent support; Alto was the only candidate in the by-election who unequivocally supported the project.[3] She was reelected to a full term on council in the 2011 British Columbia municipal elections,[4] and served as chair of the council's housing committee.[5] When the city's federal Member of Parliament Denise Savoie retired from politics in 2012, Alto was speculated as a potential New Democratic Party candidate in the resulting by-election, but declined to run.[6]
