The École Polytechnique Massacre occurred on December 6, 1989, at the École Polytechnique in Montreal, Canada. A gunman, Marc Lépine, entered the engineering school and targeted female students, killing 14 women and injuring several others before taking his own life. This tragic event highlighted issues of gender-based violence and discrimination. In response to the massacre, Canada observed December 6 as the National Day of Remembrance and Action on Violence Against Women. The incident sparked discussions about women's rights, safety, and the need for legislative changes regarding firearms and violence against women in society.
