In January 2007 it absorbed the two cantons of Avion and Rouvroy from the arrondissement of Arras. At the January 2017 reorganisation of the arrondissements of Pas-de-Calais, it gained eight communes from the arrondissement of Arras, and it lost one commune to the arrondissement of Béthune. As a result of the reorganisation of the cantons of France which came into effect in 2015, the borders of the cantons are no longer related to the borders of the arrondissements. The cantons of the arrondissement of Lens were, as of January 2015: Avion Bully-les-Mines Carvin Courrières Harnes Hénin-Beaumont Leforest Lens-Est Lens-Nord-Est Lens-Nord-Ouest Liévin-Nord Liévin-Sud Montigny-en-Gohelle Noyelles-sous-Lens Rouvroy Sains-en-Gohelle Wingles References Lens
