Former Seven Oaks School Division worker pleads guilty to sex, luring offences involving female youths

A former student support worker with the Seven Oaks School Division has admitted to sex and luring-related offences involving five female youths and other unidentified victims spanning five years.

Matthew Mousseau, 38, appeared in Winnipeg court Wednesday and pleaded guilty to two counts of sexual exploitation and one count each of luring, accessing child sexual abuse material, voyeurism, indecent exposure and providing liquor to minors.

Mousseau remains in custody and will be sentenced at a later date following the completion of reports looking into his personal background.

A former Seven Oaks School Division student support worker has admitted to sex and luring-related offences involving five female youths and other unidentified victims spanning five years.

Court heard the Crown will be seeking a sentence of up to 28 years in prison.

Mousseau worked as an educational support worker for the school division from September 2016 to June 2018, and as a student-parent support worker from August 2018 until October 2020. He was previously listed online as a student-parent support worker for the division’s Wayfinders mentorship program.

Mousseau was first arrested and charged with voyeurism in May 2024 after police conducting a shoplifting investigation at Polo Park mall found him in possession of a cellphone he had “strategically” taped inside a shopping bag next to a small hole, Crown attorney Alanna Littman told court, reading from an agreed statement of facts.

Mousseau gave police permission to look at his phone. Police reviewed then-recent photos and videos on his phone that captured Mousseau walking closely to females in the shopping mall. His phone also contained several videos of young girls engaged in sex acts.

In July 2024, police interviewed Mousseau about allegations of inappropriate sexual contact involving a 17-year-old female student. Mousseau confirmed the sexual contact, disclosed that his phone contained child sexual abuse material and that he had been looking at such material up to three times a week for the past year.

Police secured a search warrant for Mousseau’s phone, which revealed he had “surreptitiously recorded children and adults in various states of undress” in the change room at Seven Oaks Pool between April 2023 and May 2024.

The following October, police charged Mousseau with voyeurism and child sexual abuse material-related charges.

That same month, the female student provided a detailed video statement to police, saying she had sought guidance from Mousseau in early 2024 as she grieved the deaths of two close family members.

Mousseau and the girl shared personal conversations and “increasingly more time” alone together.

“Mousseau began to message (the girl) frequently, commenting on her physical attributes and sharing plans with her for their future together,” said the agreed statement of facts.

In March 2024, Mousseau picked up the girl at her rural Manitoba home and took her to his residence, where they smoked marijuana and had sex.

In May 2024, Mousseau told the girl he could no longer see her because police “were watching him,” and he blocked her phone number. The girl later messaged Mousseau through social media and the two again met for sex.

The girl later told police Mousseau “had manipulated her, used her spirituality and sacred parts of her culture and, ultimately, that he ‘broke’ her.”

Further analysis of Mousseau’s cellphone uncovered a video showing Mousseau at home exposing his penis to a 13-year-old girl.

In September 2024, Mousseau used Facebook to contact a 15-year-old student he had worked with two years earlier and asked her if she remembered him.

“Hit me up for smoke and rides,” Mousseau wrote. “I got you if you want it. You are cool as f—k in my books. Always were.”

Mousseau later agreed to drive the teen and another girl to a liquor store and buy them alcohol. Mousseau drove the girl to his home where they drank and smoked marijuana.

On Oct. 20, 2024, following Mousseau’s initial arrest, a former high school student told police Mousseau, her support worker, had repeatedly sexually exploited her over the course of several months in 2019 when she was 17.
