This 16-day period also includes other significant dates such as December 6, which marks the Anniversary of the Montreal Massacre. In 1989 fourteen women were shot dead in the Montreal School of Engineering by a young man, who believed it was because of female students that he was not accepted into the engineering school. This brutal act triggered the creation of the White Ribbon Campaign - a global initiative by Canadian men. White Ribbon Day (25 November) is the largest effort by men across the world, working in partnership with women to end violence against women.
