The first time Autumn Peltier noticed a boil-water advisory in a First Nations community, she was just eight years old. “I asked my mom what that meant,” Peltier, who is turning 15 this week, told CTVNews.ca by phone. “When she explained to me that our water is not safe to drink, it all hit me.” The Indigenous teen from northeastern Ontario has since been advocating for clean water in First Nations communities across the country. Peltier is in New York City this week to speak about the importance of clean water at the Global Landscape Forum at the UN.
