Marc Lépine was a Canadian man born on October 26, 1964, in Montreal, Quebec. He is infamously known for the tragic events of December 6, 1989, when he carried out a mass shooting at the École Polytechnique in Montreal. During this attack, he killed 14 women and injured several others before taking his own life. Lépine's actions were motivated by a hatred of feminists, which he expressed in a letter he left behind. This incident led to significant discussions about gun control, violence against women, and the need for societal change in Canada. The day is now commemorated as the National Day of Remembrance and Action on Violence Against Women.
