The riding was created as
Hull in 1914 from parts of
Labelle and
Wright ridings. It was renamed "Hull—Aylmer" in 1984. With its large percentage of civil servants, the riding was a
Liberal stronghold for almost a century, and the safest Liberal riding in the province outside
Greater Montreal. Even when the rest of the province was turning its back on the Liberals, they survived in Hull—Aylmer in
1984,
2004 and
2006. In 2008, however, it was the only riding in Canada where four candidates received over 15% of the vote, and was the only riding in Quebec outside the Montreal area the Liberals won. In a major turnaround during the
2011 elections, however, the
New Democratic Party won the riding as part of its sweep of the
Outaouais. To date, this is the only time the Liberals have lost this riding in an election. The winner of that election,
Nycole Turmel, was the interim leader of the NDP from July 28, 2011, until March 24, 2012, following the death of NDP leader
Jack Layton. The only other time it was out of Liberal hands was from 1990 to 1993, when
Gilles Rocheleau crossed the floor to the
Bloc Québécois. Hull—Aylmer lost territory to
Pontiac during the
2012 electoral redistribution. It reverted to form at the
2015 election, when Liberal
Greg Fergus handily defeated Turmel as part of the Liberals' clean sweep of the Outaouais. Following the
2022 Canadian federal electoral redistribution, the riding lost the remainder of the Plateau neighbourhood to
Pontiac—Kitigan Zibi.
