The École Polytechnique massacre, also known as the Montreal massacre, was an anti-feminist mass shooting at an engineering school affiliated with the Université de Montréal. On December 6, 1989, Marc Lépine entered a mechanical engineering class at the École Polytechnique and ordered the women and men to opposite sides of the classroom. He separated nine women, instructing the men to leave. He stated that he was "fighting feminism" and opened fire. He shot at all nine women in the room, killing six. The shooter then moved through corridors, the cafeteria, and another classroom, targeting women for just under 20 minutes. He killed a further eight women before turning the gun on himself.
