She has been a Member of Provincial Parliament since first winning her seat in the 2012 Kitchener—Waterloo byelection.

Background

Prior to entering politics, she spent 10 years with the Toronto District School Board as an educational assistant, a school community advisor and a settlement worker for new immigrants.

Politics

Fife was elected to represent Waterloo/Wilmot as a trustee for the Waterloo Region District School Board in 2003, and was re-elected in 2006 and 2010.

In the 2007 provincial election, Fife ran as the New Democrat candidate in the riding of Kitchener—Waterloo. She came in third behind incumbent Progressive Conservative Elizabeth Witmer and Liberal candidate Louise Ervin.

After Witmer resigned to take a position with the Workplace Safety & Insurance Board, Fife ran in a by-election on September 6, 2012 to replace her. She defeated Progressive Conservative candidate Tracey Weiler by 3,748 votes. She was re-elected in the 2014 provincial election, defeating Liberal candidate Jamie Burton by 3,843 votes. She was subsequently re-elected in the 2018 and 2022 provincial elections.
