Political career
Fullerton entered provincial politics in 2016, declaring her intention to run against then-Progressive Conservative MPP Jack MacLaren in Kanata-Carleton. MacLaren caused and encountered a number of issues around this time. On May 28, 2017, MacLaren was kicked out of the Ontario PC caucus and barred from being a candidate in the 2018 election, leading to a two-way race between Fullerton and Police Sergeant Rick Keindel. Fullerton won the nomination. Fullerton came under fire during the 2018 campaign for her tweets, which were labelled Islamophobic by the Canadian Muslim Public Affairs Committee, as well as for blocking Muslim leaders in her community on Twitter. She was also accused of being in favour of a two-tier healthcare system, a claim which she disputes.
