Marc Lépine was a Canadian mass murderer from Montreal, Quebec, who, in 1989, murdered fourteen women, and wounded ten women and four men at the École Polytechnique de Montréal, an engineering school affiliated with the Université de Montréal, in the École Polytechnique massacre.

The Dawson College shooting occurred on September 13, 2006, at Dawson College, a CEGEP located in downtown Montreal, Quebec, Canada. The perpetrator, Kimveer Singh Gill, began shooting outside the de Maisonneuve Boulevard entrance to the school, and moved towards the atrium by the cafeteria on the main floor. One victim died at the scene, while another 19 were injured, eight of whom were listed in critical condition, with six requiring surgery. The shooter later committed suicide, after being shot in the arm by a police officer. It was the third fatal school shooting in Montreal, after the École Polytechnique massacre in 1989 and the shooting spree at Concordia University in 1992.
