Siddon made a return to politics when he was elected to the Board of Education in Penticton, B.C. in November 2008. His campaign was based on more openness by the board with fewer in-camera meetings. Siddon was also a strong vocal opponent to the board's decision to tear down a historic auditorium and gymnasium in the local high school. Following a successful three years on the School Board, in 2011 Siddon decided not to seek re-election, but rather ran for the position of Area 'D' Director for the Regional District of Okanagan Similkameen. Siddon defeated his two contenders, receiving 50.5% support in ballots cast. In 2014 he was re-elected as Area 'D' Director.
