Paul Leroux, 73, a former dormitory supervisor at the Beauval Residential School in the 1950s and '60s, is guilty on 10 counts of indecent assault.
The sentencing hearing was held this morning at the Battleford courthouse, which was packed with victims, family and media.
There were 17 charges altogether, including indecent assault and gross indecency. The allegations included sexual touching, oral and anal sex, and bringing boys to his room where they were given alcohol and shown pornography.
The Crown is asking for an 11 year sentence. The charges added up as consecutive sentences would equal 25.5 years, but Prosecutor Mitch Piche said a number of factors need to be considered, including how much time has passed, that Leroux was back in society and is a low risk to re-offend.
The judge reserved his decision until December 12.
Leroux defends himself
Leroux once again represented himself. He said he was at a significant disadvantage because he couldn't get proper legal advice.
He said over and over, "it's unfair to use today's standards" to sentence him. He said he should be viewed as a first time offender, because these crime happened before his last conviction, and that he questions why these victims didn't come forward 40 years ago.
"These matters could have been reported at any time in the past 40 years," he said.
Apology changes nothing: Victim
CBC News spoke with one victim, who can not be named. He said nothing will undo what happened to him and the other victims, adding that no sentence is long enough.
When asked if an apology would have helped changed anything, the victim said "No."
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. It operated from 1895 to 1983.
