Before the election, Danielson served as a public-school trustee for Wards 5 & 10, spending three terms in that role before running. Referred to as a “fly-by-night” candidate by her main competitor, Danielson ran her campaign around the issue of city bylaws and enforcement of bylaws. This included the big issue of illegal basement suites, saying “Because it’s important if the person next to you is running an illegal fourplex” along with some other quality-of-life issues ranging from semi-trucks driving on residential streets to unkempt yards. While on Council, Danielson served on the Police Commission, Standing Policy Committee as Vice Chair, and as deputy mayor in her first term.
Born in Winnipeg in 1945, Danielson moved to and grew up in Edmonton, where she graduated from high school and the University of Alberta, where she earned a Bachelor of Science degree, and worked as a nurse, community coordinator, and many other positions before moving to Calgary with her husband, Arthur Danielson. After moving to Calgary, Danielson went on to serve on a number of community roles, from founder of the Penbrooke Meadows Preschool Society, the Penbrooke Meadows Community Association, Calgary Parks Steering Committee, the Suicide Prevention Management Committee of Alberta and many other roles. Her community involvement led her to enter politics, where she first served as a trustee for the public school system, later a candidate for the provincial Liberals, and then in 1999 she ran for Council to represent Ward 10.
A year after her victory, Danielson was involved in a privacy commissioner investigation. Andrew Koeppen, who ran against Danielson for school board trustee, had penned letters expressing concern and criticism about the CBEs policy of protecting gay staff and students against potential abuse. The letters were leaked to the Calgary Herald during the schoolboard elections, which Koeppen said cost him his chances at winning. Claiming that he had been misrepresented and that his complaint stemmed from singling out gay staff and children rather than a blanket harassment policy, Koeppen won the privacy violation case and subsequently sued Danielson and others for leaking the letters.
Despite controversy surrounding the Koeppen letters, Danielson ran again in 2001, once again against (and defeating) Andre Chabot. She would run again for a third time in 2004, where she would be defeated by Margot Aftergood in what would become one of the biggest political scandals in Calgary politics.
