Longueuil—Saint-Hubert (formerlyLongueuil—Pierre-Boucher andLongueuil) is a federalelectoral district inQuebec, Canada, represented in theHouse of Commons of Canada since 2015[3]
ThisSouth Shore district in the Quebec region ofMontérégie includes the eastern part of the City ofLongueuil.
The neighbouring ridings areLongueuil—Charles-LeMoyne,Montarville,Pierre-Boucher—Les Patriotes—Verchères,La Pointe-de-l'Île, andHochelaga.
This mainly Francophone riding was one of the NDP's stronger seats on the South Shore in 2011. The NDP did well across the district, with the BQ coming in distant second for the most part. The Liberals and Conservatives did poorly in this riding, although the Liberals had a tiny pocket of somewhat strong support around Parc Michel-Chartrand.[citation needed] Despite winning the riding again in 2015, it was an extremely close contest. The Liberals surged into second place, just one point away from defeating the incumbent NDP candidate.
The electoral district was created as "Longueuil" in 1952 from parts ofChambly—Rouville andChâteauguay—Huntingdon—Laprairieridings. It was renamed "Longueuil—Pierre-Boucher" in 2004.
This riding was largely replaced with "Longueuil—Saint-Hubert", losing territory toPierre-Boucher—Les Patriotes—Verchères and gaining territory fromSaint-Bruno—Saint-Hubert during the2012 electoral redistribution.
This riding has elected the followingmembers of Parliament:
