Concerns over lead in Canada's water supplies

A large investigation into Canada's drinking water has raised concerns about lead contamination. Out of 12,000 tests since 2014, a third exceeded the national safety guideline of 5 parts per billion. The results drew comparisons with the public health crisis in the US city of Flint, where a decision to draw water from older, corrosive pipes exposed up to 100-thousand people to high lead levels. The investigation was a year-long collaboration by 120 journalists across 10 media outlets and nine universities. Rob Cribb lead the investigation for the Toronto Star and talks to Kathryn about what happens next.
