Premier Dalton McGuinty is not ruling out a Commission of Inquiry into the deaths of seven First Nations students in Thunder Bay. McGuinty says the call by the Nishnawbe Aski Nation is now in the hands of the government's Child Advocate. He's hoping to bring various levels of government to the table to come to grips with the problem. As well, McGuinty has again ruled out joining next week's leaders debate on Northern issues.
