Mansur is featured on the documentary Obsession: Radical Islam's War Against the West produced by the David Horowitz Freedom Center. He also unsuccessfully ran for the Canadian Alliance party in 2000.

Mansur has been accused by Canadian Islamic Congress of using "provocative, self-serving rhetoric", and for "promoting an anti-Arab and anti-Muslim agenda".

He is an Ismaili Muslim.

At a press conference on October 2, 2008, Mansur stated that "Islam is my private life, my conscience...[but] my faith does not take precedence over my duties...to Canada and its constitution, which I embrace freely;" "I am first and most importantly a Canadian;" "only in a free society will you find Islam as a faith and not a political religion." Mansur also criticized New Democratic Party Leader Jack Layton, whom Mansur said "has gone to bed with Islamists", because he is running candidates in Ontario and Quebec who are closely identified with the push for Sharia law.
