Interim Chief Morley Watson of the Federation of Saskatchewan Indian Nations says an inquiry is needed to find out why First Nations women are more often the victims of violence than any other demographic in Canada.
He says his group believes there are as many as 61 missing or murdered women with First Nations ancestry in Saskatchewan alone.
Last week, Manitoba chiefs and the federal New Democrats called for a national inquiry into the growing number of aboriginal women across the country who have fallen victim to violent crime.
The demand came after 52-year-old Shawn Cameron Lamb was arrested and charged in the deaths of three aboriginal women in Winnipeg.
David Harper, head of Manitoba Keewatinowi Okimakanak, the organization for northern chiefs, said he and other leaders sent a letter to the prime minister that asks him to commit to an inquiry by July 10.
The Manitoba government has turned aside calls for a provincial inquiry, saying it doesn't want to interfere with criminal proceedings against Lamb.
The FSIN also called on the Saskatchewan government and the official Opposition to support an inquiry.
