From CBC News:

Family and friends of missing aboriginal women were set to hold a rally in Edmonton on Saturday to raise awareness of the unsolved disappearances.

Organizers of the Stolen Sisters Awareness March say they’re staging the event to remind people of the grim realities some aboriginal women face.

They say far too many — in particular those who live on the streets, are drug addicts or work as prostitutes — have disappeared without their families knowing what has happened to them.

April Eve Wiberg, one of the organizers, said that over the last 20 years, more than 500 aboriginal women in Canada have been murdered or they’ve just disappeared.
