Three Catholic priests have been elected to the House of Commons of Canada.

Andrew Hogan was the first Catholic priest to serve as a Canadian Member of Parliament.

Hogan was a member of the New Democratic Party.

Robert Ogle was elected to the House of Commons in 1979 in the electoral district of Saskatoon East, Saskatchewan. Ogle was re-elected in 1980. He chose not to seek re-election in 1984 as a result of the new ban by the Holy See on clergy in public office. Like Hogan, Ogle was a member of the New Democratic Party.

Raymond Gravel was elected in a 2006 by-election in the electoral district of Repentigny, Quebec. He had received a dispensation from his diocesan bishop to enter politics. Gravel did not seek re-election in the 2008 federal election after Holy See authorities ordered him to choose between politics and the priesthood following controversy over his opposition to anti-abortion Bill C-484 and his support for the Order of Canada nomination of abortion rights activist Henry Morgentaler. Although he chose to leave politics, Gravel maintained that he remained, in accordance with Catholic doctrine, opposed to abortion. Gravel was a member of the nationalist Bloc Québécois.
