For a long time this riding was considered a Liberal stronghold, having been won by the Liberal Party of Canada in all but one election since 1980. Longtime Liberal MP Jim Peterson was the riding's MP from 1980 to 1984 and from 1988 to 2007, and Martha Hall Findlay was the riding MP from 2008 to 2011. Long considered a safe Liberal seat, Conservative candidate Chungsen Leung won by 932 votes on the May 2, 2011 federal election. In the 2015 federal election, the seat returned to the Liberal Party with Ali Ehsassi unseating Leung.
