A victim is wheeled away from the University of Montreal after gunman Marc Lepine opened fire at the school in Montreal on Dec. 6, 1989. Prime Minister Stephen Harper is urging Canadians to eliminate violence against women as the country marks the 21st anniversary of the Montreal massacre. In 1989, Lepine gunned down 14 female students at Montreal's Ecole Polytechnique. THE CANADIAN PRESS/Shaney Komulainen
