This riding has elected the following members of Parliament: Assad represented Gatineau—La Lièvre from 1988 to 1997 which was known as Chapleau from 1987 to 1988.

Like most ridings in the Outaouais, Gatineau had long been safe for the Liberals, save for a lone Progressive Conservative victory in their 1984 nationwide landslide.

The Bloc managed to hold the seat with just over 29% of the vote in 2008, by far the lowest percentage for a winning candidate nationwide, due to a near-three-way split between themselves, the New Democratic Party and the Liberals.

In the 2015 election, Liberal candidate Steve MacKinnon, running a second time, defeated NDP incumbent Françoise Boivin in an upset with an almost 40-point swing.
