It's a sentence decades in the making for Leroux's victims. The Crown is asking for 11 years in prison.
Leroux worked at the Beauval Indian residential school nearly 50 years ago. Last month, he was found guilty on 10 counts of indecent assault.
CBC News spoke with one victim, who cannot be named. He said nothing will undo what happened to him and the other victims, adding that no sentence is long enough.
"It doesn't matter what he gets," the victim said. "The damage is done. He's stolen many years from us. Whether he gets two, three, four, 10 years, it doesn't matter."
The charges added up as consecutive sentences would equal 25.5 years. However, prosecutor Mitch Piche said he doesn't believe the law would allow such a sentence.
Leroux, who is now 73 years old, has been representing himself in court. He maintains he did not commit the crimes and he's also not apologizing.
Leroux also has convictions from his time working at a residential school in Inuvik during the 1970s. He was sentenced to 10 years in 1998 for sexually abusing boys there.
The Beauval school was operated by the Catholic Church under the supervision of the federal government, from 1895 to 1983.
