"Sisters in Spirit" vigils are taking place across Canada on Friday, to shed light on and honour missing and murdered indigenous women. The Native Women's Association of Canada estimates that approximately 580 indigenous women have disappeared or been murdered in the past two decades. Indigenous women are also reportedly five to seven times more likely than other women in Canada to die as a result of violence.
