M.P. Dean Allison and Phil McColeman as 2013 Canadian delegation attended the Parliamentary Assembly of the Organization for Security and Co-operation in Europe’s Annual Session

Since taking office, Allison has served on the Standing Committee on Public Accounts, International Trade and as past chair of the Standing Committee on Human Resources Skills Development and Status of Persons with Disabilities and has also served on the advisory panel on the Funding of Officers of Parliament. He has also served as vice chair of the Ontario Conservative Caucus and been on the executive of the Intraparliamentary Union Association and the Commonwealth Association.

In the 42nd Parliament, Allison served as the Shadow Minister for International Trade as well as the vice-chair of Standing Committee on International Trade.

Allison is also a director of the Organization for Security and Cooperation in Europe Parliamentary Assembly.

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]}
