Since 1991, the anniversary of the massacre has been designated the National Day of Remembrance and Action on Violence Against Women, intended as a call to action against discrimination against women. A White Ribbon Campaign was launched in 1991 by a group of men in London, Ontario, in the wake of the massacre, for the purpose of raising awareness about the prevalence of male violence against women, with the ribbon symbolizing "the idea of men giving up their arms". Commemorative demonstrations are held across the country each year on December 6 in memory of the slain women and numerous memorials have been built.
