McAllister became a Wildrose party member after just a month of looking for work. McAllister was avid critic of the long seated Alberta PC party and he was particularly effective in criticism of the PC governments lack of education reform. In the 2012 fall Legislative session as a member of the Wildrose party, McAllister brought forward
amendments to the Education Act that would have ended school fees for mandatory curriculum activities, and would have guaranteed the rights of teachers to grade students with a zero where warranted. On December 17, 2014, he was one of nine Wildrose MLAs who defected from the Wildrose party and crossed the floor to join the
Alberta Progressive Conservative caucus. On December 18, 2014, the President of the Chestermere-Rocky View PC constituency association said that "...people in our constituency right now that are lost. They are dumbfounded..." By February however, McAllister was soon welcomed by PC Party leadership in Edmonton as one of their own even though local support remained questionable. In March 2015, in the
pre-writ period of
that year's election, McAllister had two declared competitors for the riding of Chestermere-Rocky View. One was Jamie Lall, a long time PC party member and local resident, competing against McAllister for the PC nomination. The other was
Leela Aheer, who was running as the Wildrose candidate. While some in the PC party continued to be critical of McAllister's decision to change parties without a democratic process, he remained confident in his decision; “Although I can’t speak for all of them, those people that wrote cheques and supported me as a Wildrose MLA, to the large degree, those same people will be writing cheques for me as a PC MLA". In February 2015 several high profile PC party members including the Premier came to Chestermere with McAllister in campaign-style event that was geared to supporting the local PC party including McAllister. On March 23, 2015, McAllister voted in favour of the Tories' 2015–16 Alberta budget which contained the largest cumulative tax increase and the largest annual budget deficit in Alberta history. McAllister was defeated in the
2015 election by Wildrose candidate
Leela Aheer.
Moderating incident On September 29, 2025, McAllister served as moderator at Premier Danielle Smith’s Alberta Next panel. During the Q&A, when a high-school student in attendance began to ask a question about the Smith government's diversion of public funding to private schools, their microphone was cut. McAllister then openly berated the student for their tone, claimed the student wasn't making any sense, and said “Your parents should turn you over your knee”. Video showed McAllister was swiftly met with a negative reaction from the audience, who booed and jeered. One audience member in attendance called McAllister's remark "disgraceful". The student's censored query came just two days following a province-wide student walkout and "Save Alberta’s Education" rally protesting the province's education funding, recent controversial book ban, and transgender laws, which Premier Smith said she is willing to override Charter Rights to push through.
Nativism comments On February 19, 2026, McAllister ranted in a social media post that he was disgusted with Canada’s immigration policies and that governments where importing " from nations with failed systems when our Judeo-Christian heritage and principles have worked so well here?’”
Anna Triandafyllidou, an expert on immigration at
Toronto Metropolitan University. pointed out "Canada was not just built by people from Western European or Anglo-Saxon descent" and that small towns in Alberta benefited to immigration such as
Brooks. Christopher Worswick, an economics professor at
Carleton University, took issues with McAllister’s emphasis on immigrants with Judeo-Christian values, saying that "it goes against
Canadian values of treating everyone fairly and equally and not prioritizing one culture over another". Smith defended McAllister. ==Electoral history==
