Allison has tabled a number of different legislative initiatives in Parliament including a bill aimed at removing the faint hope clause from the Criminal Code,^[4] and motions to entrench property rights in the Canadian Charter of Rights and Freedoms^[5] and to raise awareness of Anaphylaxis.^[6]

Allison was one of thirteen Canadians banned from traveling to Russia under retaliatory sanctions imposed by Russian President Vladimir Putin in March 2014.^[7]

After the House of Commons introduced a vaccine mandate, Allison claimed a medical exemption. He attended House meetings virtually.^[8]

In February 2023, Allison, along with fellow Conservative MPs Leslyn Lewis and Colin Carrie, had dinner with Christine Anderson, a Member of the European Parliament representing Alternative for Germany, who was on a Canadian tour of right-wing media and convoy protest supporters. The meeting was condemned by the Centre for Israel and Jewish Affairs, the Canadian Anti-Hate Network, and Prime Minister Justin Trudeau among others, for Anderson and AfD's Islamophobic and antisemitic positions. Conservative leader Pierre Poilievre also denounced Anderson's views as "vile", racist, and said that "it would be better if Anderson never visited Canada in the first place".^[9] The three MPs released a joint-statement saying that while meetings with foreign elected officials are ordinary, they were unaware of her or her party's views, and that they condemned racist and hateful views.^{[9][10][11][12]}
