In the
2006 federal election, Gill ran in
York West, and lost to Liberal MP
Judy Sgro by over 15000 votes. In the
2008 federal election, Gill ran in
Brampton—Springdale against incumbent
Ruby Dhalla, but was narrowly defeated by 773 votes. He was elected as a
Conservative Party of Canada Member of Parliament representing
Brampton Springdale in the
2011 election, defeating Dhalla. After witnessing increased gang activity in his riding, Gill toured Western Canadian cities in December 2011 to speak with police and community organizations to see how this could be stopped. In May 2012, Gill introduced a
private members bill, C-394, which made it a crime to target someone for recruitment into a gang. It was eventually passed into law in June 2014. In September 2013, Gill was appointed Parliamentary Secretary to the
Minister of Veterans Affairs. In January 2015, Gill was appointed by Prime Minister Stephen Harper to the role of a Parliamentary Secretary to the
Minister of International Trade. In May 2015, Gill wrote letters of support to the
Canadian Radio-television and Telecommunications Commission (CRTC) for two of his constituents' competing applications for a community radio station in Brampton. The
Conflict of Interest Act bars parliamentary secretaries from writing such letters to the CRTC and other administrative tribunals, and in October 2013, ethics commissioner
Mary Dawson had issued a directive to that effect. The Ethics Commissioner ruled in February 2016 that although he had acted in good faith, Gill had violated the
Conflict of Interest Act.
2015 election Redistribution of federal ridings took place and concluded shortly before the
2015 federal election. Gill's riding, Brampton-Springdale, was eliminated, and he ran in the new riding of
Brampton North. During the election, Gill criticized the provincial
Ontario Liberal Party and Premier Kathleen Wynne's proposed updates to the sexual education curriculum, which had not been changed since 1998. The changes included teaching that
homosexuality was acceptable in Grade 3, teaching about
puberty in Grade 4 as opposed to Grade 5, and teaching about
masturbation and
gender expression in Grade 6. Gill described the changes as "graphic and explicit" in a taxpayer-funded mailout which conflated the provincial party's education policies with those of separate federal Liberal party, which has no constitutional jurisdiction in the field. In the mailout, Gill also said that it was part of a Liberal attack on
family values and parent's right to control the education of their children. In a 2015 video with the
Punjabi Post, Gill described some segments of the new education curriculum as "disgusting." Gill lost to Liberal candidate
Ruby Sahota.
Provincial politics On October 29, 2016, Gill announced that he would seek the
Progressive Conservative Party of Ontario nomination in
Milton for the
42nd Ontario general election. On June 18, 2017, he won the nomination. In June 2017, then Progressive Conservative leader
Patrick Brown stated that Gill's position on gay rights had shifted, and he was now "100 per cent" in favour of gay rights after comments stating that Gill said that he became involved in politics due to his opposition to legalizing
same-sex marriage were uncovered. In 2021, he was appointed the
Ontario Minister for Citizenship and Multiculturalism from 2021 to 2022, when he became the Minister of Red Tape Reduction. Gill officially resigned as MPP on February 16, 2024. The
provincial by-election to replace him was held on May 2, 2024. The seat was retained by the Progressive Conservatives.
45th Canadian federal election On January 25, 2024, Gill announced that he would be resigning as a Minister and MPP to run in the
45th Canadian federal election in
Milton. After the riding was split into
Burlington North-Milton West, and
Milton East-Halton Hills South, Gill planned to seek a seat in Milton East-Halton Hills South. Keene, who ran tried running in the nomination for Milton East-Halton Hills South, never received nomination papers and suggested this was because the party preferred Gill as their candidate. Gill was defeated in the 2025 election. Although preliminary results suggested he had narrowly won the riding, a subsequent vote validation process by
Elections Canada revealed that
Liberal candidate
Kristina Tesser Derksen had won the seat by a margin of 29 votes, overturning Gill's initial lead. Because of the narrow margin, a judicial
recount was automatically triggered. Following a three-day recount, Tesser Derksen's victory was confirmed with a revised margin of 21 votes. ==Personal life==
