Lesser Slave Lake is a provincial electoral district for the Legislative Assembly of Alberta, Canada. It has existed since 1971 and is mandated to return a single member using the first past the post method of voting. The riding is named after the lake of the same name, which is located entirely within its borders. Geography Lesser Slave Lake is a predominantly rural riding located in Northern Alberta. There are no cities in the riding. It includes only two incorporated urban municipalities: the towns of High Prairie and Slave Lake. The riding also includes the entirety of one rural municipality (the Municipal District of Opportunity No. 17) and parts of three others (Big Lakes County, the Municipal District of Lesser Slave River No. 124, and Northern Sunrise County). Eleven First Nation bands are based in Lesser Slave Lake: Bigstone Cree Nation, Driftpile First Nation, Kapawe'no First Nation, Loon River Cree Nation, Lubicon Lake Indian Nation, Peerless Trout First Nation, Sawridge First Nation, Sucker Creek Cree First Nation, Swan River First Nation, Whitefish Lake First Nation, and Woodland Cree First Nation. Most of the region's Indigenous population is of Cree origin. The riding borders five other electoral districts: Peace River to the northwest, Fort McMurray-Wood Buffalo to the northeast, Fort McMurray-Lac La Biche to the east, Athabasca-Barrhead-Westlock to the south, and Central Peace-Notley to the west. History The electoral district was created in the 1971 boundary re-distribution from the electoral districts of Grouard and Peace River. The district remained largely unchanged until the 1993 boundary re-distribution when the electoral district was extended north to the Northwest Territories, Alberta border. The 2003 boundary re-distribution saw the district revert to similar boundaries that existed prior to 1993. The 2010 boundary re-distribution saw the district re-aligned with current municipal boundaries with a portion of land on the south end moved into Barrhead-Morinville-Westlock. In the 2017 electoral boundary re-distribution only minor changes were made to the districts boundaries, which were enlarged to include the Calling Lake Reserve. Lesser Slave Lake is one of two electoral districts in the province that are afforded the exemption provided in the Electoral Boundaries Commission Act whereby only four electoral districts in Alberta may have a population which is as much as 50% below the average population of all the proposed electoral districts. The rationale for this exemption is the relatively low population in the region and large distances between
