Jean Lépine was a Canadian man known for his tragic involvement in the Montreal Massacre on December 6, 1989. During this event, he entered the École Polytechnique and opened fire, targeting female students. This act of violence resulted in the deaths of 14 women and injuries to several others, making it one of the deadliest school shootings in Canadian history. Lépine's actions were motivated by a hatred of feminists, which he expressed in a letter he left behind. The incident sparked national discussions about gun control, violence against women, and the need for societal change in addressing gender-based violence in Canada.
