A documentary about folk legend Buffy Sainte-Marie, which debuted at last year’s Toronto International Film Festival, has won an International Emmy Award.

The film was made before her Canadian Indigenous roots were called into question.

“Buffy Sainte-Marie: Carry It On,” won the Emmy in the arts programming category.

Producers describe the film as a retrospective of Sainte-Marie’s life and career.

However, the 82-year old singer-songwriter’s ancestry was challenged in a TV investigation last month, that presented several identity documents suggesting she is actually Italian-American.

Saint-Marie has denied the accusations.
