Like many of her past works, the 82-year-old filmmaker says Trick or Treaty? aims toeducateCanadians about the true nature of the country's past.

Her passion about her life's mission was evident in an emotionalinterview Friday with CBC Arts reporter Zulekha Nathoo.

"When we talk about our people, or talk about our history, and you mention the word 'treaty' it's nothing to people," said Obomsawin.

"They should learn what the real truth is about the people who came here that were strangers and robbed us of everything and damaged a people and used theirnaivete,to make them believe something else. That's important."
