Canadian federal elections have provided the following results in Central Quebec.
In fact, before 2011, the BQ won at least seven of its nine seats in each of the preceding four elections, losing Saint-Maurice (Jean Chrétien's old riding) in 1993, 1997 and 2000 and Portneuf in 2000, which both went Liberal.
They swept all nine ridings in 2004, and in 2006 and 2008 lost only Lotbinière—Chutes-de-la-Chaudière to the Conservatives and Portneuf-Jacques-Cartier to independent candidate André Arthur.
The 2011 NDP surge saw New Democrats sweeping all but two seats in the region, with the Conservatives and Bloc Québécois holding one each.
In 2015, Bloc Québécois rebounded to take three more ridings, while the Liberals regained Saint-Maurice—Champlain.
