This northern riding is among the largest in Canada. Incumbent New Democrat Niki Ashton held the seat in 2015, despite rising Liberal fortunes elsewhere in Manitoba. She faces competition this time from a Liberal who recently represented the region in the Manitoba legislature. The seat is traditionally NDP, but has swung Liberal in the past and was held by Progressive Conservatives in the 1960s and 1970s.
