David Norton, a former Anglican priest and pastor at St. Andrews on the Chippewas of the Thames First Nation, has been convicted on numerous sex-related charges involving young boys.
Justice Lynda Templeton handed down her verdict at the London courthouse around noon on Tuesday.
She says it was "A difficult and emotional case," but ultimately, "I find that I don't believe Mr. Norton's testimony, his evidence simply did not ring true."
Closing statements had concluded on Friday, with Crown Attorney Chris Heron telling the court, "The accused was in a position of trust...setting the scene to commit...sexual acts," that violated the four complainants.
All four were altar servers from eight to ten years old who had sleepovers at Norton's home in the 1970s.
The trial heard how Norton allegedly drugged the boys and touched their private areas. The testimony was, at times, extremely difficult to hear.
Norton, 72, who is already serving time for a similar case, had pleaded not guilty to indecent assault and sexual assault.
He is expected to be sentenced in this case in January when the four complainants will be able to deliver victim impact statements.
