The Ontario Native Women's Association is calling on the Harper Government to do more for aboriginal women. Spokesperson Lorene Rego says violence against First Nations women is a growing issue and the current form of anti-violence programs are not working. The sixth annual Sisters in Spirit Vigil will be held at noon on Tuesday at Hillcrest Park. There are seventy cases of missing or murdered aboriginal women in Ontario and most of those are from the bigger city centres like Thunder Bay.
