The bio states that Mr Saganash is a residential school " survivor" 

A check on Wiki says this ..

"At the age of seven, he was among 27 Cree children taken from their homes to attend French-language schooling in La Tuque, while living with an English-speaking Anglican family.[4] The program was cancelled the following year, but he remained there for ten years, completing his schooling in French."

"After that, he attended a meeting on the negotiations between the Cree and Government officials on constitutional and resource rights, which sparked his interest in pursuing a law degree. He attended law school at the Université du Québec à Montréal and in 1989 he became the first Cree to receive a law degree in Quebec.[6] Saganash is fluent in Cree, French and English."

you generally don't equate voluntary attendance and the gaining of proficiency in 3 languages and a degree in Law as surviving...but maybe there's been a change in the usual interpretation of the word
