Dougall stood as council candidate in the Linwood Borough for the election on 10 September 1896, but he came fifth, and as there only three positions available, he was not successful. He was a member of the
Riccarton Road Board (1901–1910). He successfully stood for
Christchurch City Council in the Central Ward in the April 1909 election, coming fifth out of ten candidates vying for six available positions.
Henry Holland, a later mayor, came eight in this election and was thus unsuccessful. At the next election in April 1911, he was returned at the head of the poll in the Central Ward (with Henry Holland in second place).
Tommy Taylor, the new mayor elected at the April 2011 election, died after only three months in office. Dougall initially deputised as mayor after Taylor's death and at the next council meeting on 31 July 1911, he was unanimously elected the next mayor by his fellow city councillors. Many of them lamented the antiquated legislation which did not allow for an election at large in case of the death of the incumbent mayor. Since the December 1876 election when
James Gapes was returned, mayors had been elected at large. Dougall was succeeded as a city councillor by
Henry Acland. During his term as mayor, the foundation stone for the Government Building (a Category 1 heritage building) in
Cathedral Square was formally laid by
Prime Minister Sir
Joseph Ward in the presence of many members of parliament. Dougall presided over the ceremony. Wordsworth Street was extended to
Colombo Street and then used by the rerouted
Opawa tram route as a considerable improvement. Steps were taken for the city council to purchase the
Canterbury Provincial Council Buildings from the
Government. The next mayoral election was held on 24 April 1912, and it was contested by Dougall, Henry Holland, and
Henry Thacker. Like the previous election in April 1911, the incumbent came last. Holland was successful with 4,127 votes, with Thacker and Dougall receiving 2,931 and 2,637 votes, respectively. Holland was installed as mayor on 1 May 1912. ==Community involvement==
