Patrick first contested the
1891 North-West Territories general election in the
Wallace electoral district, finishing second to
Joel Reaman. Patrick again ran for office in the October 1897 by-election for the
Yorkton electoral district and was acclaimed, and in the subsequent
1898 North-West Territories general election, was acclaimed again. In the
1902 North-West Territories general election Patrick defeated J.E. Peake with 408 votes to Peake's 141. In the Assembly, Patrick was a supporter of the
Frederick W. A. G. Haultain government and responsible government for the North-West Territories until 1902 when he disagreed with Haultain's goal of a single large province across the western Prairies. Instead, Patrick envisioned provinces with boundaries similar to the borders that have been adopted for the provinces of Alberta and Saskatchewan. Patrick stepped down from the Assembly in 1904 to run in the
1904 Canadian federal election and bring forward the issue of provincial status for the North-West Territories. Shortly after Patrick accepted the
Conservative nomination, Laurier announced that the Dominion government would provide province status to the southern parts of the North-West Territories. Patrick stated that he would not have run if he knew the announcement would occur. Patrick did not win, coming in a distant second in the
Mackenzie electoral district to
Liberal Edward L. Cash, who was also a doctor in Yorkton. == Legacy ==
