[3][4] An opposition to pandemic-related public health measures was at the centre of Wilson and Ritz's efforts in early 2022, and they worked alongside members of the anti-mandate group Unified Grassroots.

[10] On Wilson's first day in the Legislature as SUP leader, she invited guests who purported to have suffered "vaccine injuries" and urged the government to meet with them.

[11] The party hosted an official launch event on February 28, 2023 in Saskatoon, where it introduced its logo and policy agenda.

[24] In September 2024, two more former Saskatchewan Party MLAs, Greg Brkich and Denis Allchurch, announced that they would run for SUP in the fall election.

[25] Hromek launched the party's campaign on October 2, 2024, stating that he hoped to have at least two candidates elected to the Legislative Assembly.

[29] Hromek stated that SUP "can hold our head high and be proud of ourselves with what we accomplished", taking credit for pressuring the Saskatchewan Party to move further right in its policies.

[34] Upon the launch of the party, Saskatoon StarPhoenix columnist Phil Tank noted the SUP's promotion of policy positions consistent with right-wing populist movements, such as stances against mass immigration, COVID-19 lockdowns, and vaccine mandates.

The SUP supports the removal of "ideology" and "indoctrination" from school curricula—with Hromek citing "genders" and the climate crisis as examples—and pledged to defund post-secondary institutions that do not "uphold and defend freedom of expression on campus".
