Harold "Buckley" Belanger (born March 21, 1960) is a Canadian provincial politician, who served as the Member of the Legislative Assembly of Saskatchewan for the constituency of Athabasca, in the north-western corner of the province.[1] He is a member of the provincial New Democratic Party and the federal Liberal Party of Canada.
He was originally elected to the Legislative Assembly in the 1995 general election as a Liberal member. He left the party to join the NDP in 1998, recontesting his seat in a by-election in which he attained 93.64 per cent of the vote, the second highest margin of victory ever attained by an electoral candidate in the province. Belanger has been re-elected in every election since then, most recently in the 2020 general election, in which he was re-elected with a majority of 618.
Prior to his election to the legislature, Belanger served as mayor of Île-à-la-Crosse, and worked as a journalist and administrator for MBC Radio. On August 15, 2021 he resigned from the legislature to run in the 2021 Canadian federal election, as a federal Liberal in the riding of Desnethé—Missinippi—Churchill River. He was defeated by Conservative candidate Gary Vidal.[2]
