Prior to being appointed to office, Van Bibber worked for the Yukon Department of Finance. She was also instrumental in the formation of the Yukon First Nations Culture and Tourism Association, as a private tour operator.
Van Bibber announced her intention to seek the Yukon Party nomination in its stronghold riding of Porter Creek North in the 2016 Yukon election, which had been vacated after the incumbent Yukon Party representative, Doug Graham, announced his retirement. Although highly unusual for a former Commissioner to run for elected office - given the position's non-partisan nature - she was not the Yukon's first Commissioner to later seek elected office, and was already serving in a partisan role at the time as Senior Advisor to the Premier in the Yukon Party Cabinet Offices. She was elected to the Yukon Legislature for the riding of Porter Creek North on November 7, 2016.
Van Bibber is currently a member of the Standing Committee on Statutory Instruments and the Standing Committee on Appointments to Major Government Boards and Committees. She is also the Yukon Party caucus critic for the Department of Education, the Aboriginal relations branch of the Executive Council Office, and the Department of Tourism and Culture.
Van Bibber was appointed a Commander of the Order of St. John in 2006 and was appointed as a member of the Order of Canada - one of Canada's highest civilian honours - in 2016. Her citation into the Order of Canada recognizes her "role in making the territory a travel-destination by coordinating its tourism industry and broadening awareness of its unique Indigenous cultures."
