Saskatchewan Party MLA

Before entering provincial politics, Wilson was twice elected Reeve of the Rural Municipality of Paddockwood.^[2] Wilson was first elected to represent the electoral district of Saskatchewan Rivers in the Legislative Assembly of Saskatchewan in the 2007 election, defeating incumbent New Democratic Party and cabinet member Lon Borgerson.^[3] Wilson was re-elected in the 2011, 2016, and 2020 provincial elections.

In 2009, Premier Brad Wall appointed Wilson as Legislative Secretary to the Minister responsible for Immigration - New Citizen Initiative. After the 2011 provincial election, Wilson was appointed Chair of the Standing Committee on Private Bills and the Private Bills House Committee, as well as Deputy Caucus Chair.^[4] In a June 2014 cabinet shuffle, Wilson was appointed Provincial Secretary and Legislative Secretary to the Premier.^[5]

In 2019, Wilson was charged with two counts of common assault after a conflict with her step-mother and step-brother about care for her father, who died later that year. Wilson reportedly forced her way into an apartment during the conflict.^[6] The case was referred to mediation, and at the conclusion of that process the assault charges were withdrawn.^[7][8] Wilson resigned from her position as Provincial Secretary in the cabinet, but remained in the Saskatchewan Party caucus throughout the process.^[9]

Wilson let her name stand to become the new Speaker of the Legislative Assembly in 2020, but Randy Weekes was chosen instead; Wilson ultimately served as Deputy Speaker.^[10] Wilson also served as Saskatchewan-Ukraine Relations Liaison.^{[citation needed]}

Saskatchewan United Party

In the spring of 2022, Wilson was part of an effort, alongside former Conservative Member of Parliament and federal agriculture minister Gerry Ritz, to establish a new conservative provincial party.^[17] Early efforts reportedly involved an attempted "takeover" of the provincial Progressive Conservative party, with a plan to rebrand as the Conservative Party with Wilson as leader.^[17][18] When that effort failed, focus shifted to starting a new party, with organizers publicly noting an opposition to pandemic-related public health measures.^[19] On November 30, 2022, the Saskatchewan United Party (SUP) was registered with Elections Saskatchewan, with Wilson appointed party leader and becoming its first member in the Legislature.^[1][20] Wilson stated that her priority was securing an inquiry into the government's handling of the COVID-19 pandemic in Saskatchewan; she also invited guests to the assembly who claimed to have experienced "vaccine injuries", and asked the government questions about vaccine safety. Wilson was again met with calls to resign and trigger a by-election for her seat.^[20]

On February 28 2023, Wilson and the SUP held an official launch event in Saskatoon, branding itself as the "conservative option for Saskatchewan".^[21][22]

The SUP ran its first candidate in a by-election on August 10; Jon Hromek finished second to the Saskatchewan Party's Blaine McLeod in the Lumsden-Morse contest, claiming 23% of the votes. Wilson stated that she was "very pleased" with the result, and attributed it to the party advocating for more parental involvement in the education system.^[23] Later that month, the Saskatchewan Party government introduced new education policies restricting sexual health education and requiring parental consent for children under 16 wishing to have their chosen names and pronouns affirmed at school; the government went on to introduce legislation titled the "Parents' Bill of Rights". Wilson supported the legislation and took credit for forcing the government to introduce it, and also for its willingness to invoke the notwithstanding clause to turn it into law after a court injunction against the policy was granted in September.^[24][25] On October 20, 2023, Wilson voted with the Saskatchewan Party to pass the bill.^[26]
