System (CIMS) was a secretive database used to track and control Canadians' information and voting preferences, and said that Harper could simply "switch off" this system to punish an MP. Parliamentary work For his tenure as an MP, Mark was always a "backbencher". In 2001, as the Alliance's parliamentary critic for Immigration, Mark was responsible for expressing his party's position on the Liberal government's Immigration and Refugee Protection Act, which he did during the immigration controversy involving the Sklarzyk family who, as a result of an administrative error, was deported from Canada to Poland in May 2001. He also contributed to the parliamentary committee's work in drafting the final version of the bill, and was generally regarded by MPs from all parties as having made several constructive criticisms to the legislation.

Federal resignation and return to municipal politics Mark announced in June 2009 that he would be resigning before the next federal election.

Return to federal politics and switch to Green Party of Canada Mark announced on November 13, 2014, that he would be running as an independent candidate for the 2015 federal election in Dauphin—Swan River—Neepawa, which includes nearly all of his old riding. Mark announced that he is now a member of the Green Party of Canada, but would still seek election in 2015 as
