The first Take Back the Night Marches are organized in cities across the country to protest rape and other forms of sexual violence against women and to reclaim the streets. The Vancouver march in 1978  was organized by an ad hoc group known as the “Fly-by-Night” collective on unceded Coast Salish Territory.  In 1981, The Canadian Association of Sexual Assault Centres declared that Take Back the Night marches would be held on the third Friday in September so women would be marching on the same night all across Canada .
