In the
2011 Canadian federal election, Lizon ran as
Conservative candidate in the riding of
Mississauga East—Cooksville. He defeated
Liberal candidate
Peter Fonseca by 676 votes. In September 2011, Lizon introduced Bill C-266, An Act to establish Pope John Paul II Day, also called by its short title:
Pope John Paul II Day Act. A similar bill was first introduced in October 2010 by Liberal MP
Andrew Kania. Both bills sought to recognize April 2 as a day to honour the memory of the late
Pope John Paul II. Bill C-266 received Royal Assent on December 16, 2014, becoming law. April 2, 2015, the 10-year anniversary of the death of Pope John Paul II, was incidentally the first Pope John Paul II Day observed in Canada. In 2012, Lizon was criticized by the
South Asian community and other members of parliament when he sent out a survey to his constituents asking what languages they spoke, with one of the languages listed as "Indian".
Jim Karygiannis, the Liberal MP for
Scarborough—Agincourt, issued a press release calling the mailer insulting and comparing it to asking someone if they speak "Canadian" or "Mexican". In 2013, Lizon joined two other Conservative MPs –
Maurice Vellacott and
Leon Benoit – in writing a letter to the
RCMP requesting a homicide investigation into some late-term abortions that may have resulted in live births. The letter was criticized as an attempt to reopen the abortion debate.
Prime Minister Stephen Harper said, "I think all members of this House, whether they agree with it or not, understand that abortion is legal in Canada and this government, myself included, have made it very clear that the government does not intend to change the law in this regard." In the
2015 election, Lizon again faced Fonseca. This time, Fonseca defeated him by 9,801 votes. Lizon was defeated by Fonseca again in the
2019 election, this time by a margin of 10,259 votes. In the
2025 election, Lizon ran as the Conservative candidate in the newly created
Taiaiako'n—Parkdale—High Park electoral district, placing third. ==Electoral record==
