A First Nations high school student in Saskatoon is giving the prime minister a failing grade for one of his answers.

Grade 12 student Tahris Bear asked Justin Trudeau at an event at her school Wednesday how he'll right the wrongs faced by Canada's indigenous peoples and why he allows them to live in Third World conditions.

Trudeau said Ottawa can't fix the situation on its own, adding that previous, well-meaning federal governments tried, but with horrible consequences.

He said everyone would have to work together.

But Bear said afterward that she didn't think Trudeau answered her question.

She said he didn't offer up any concrete actions for what steps the government would take to make the living conditions better.
