The Ontario Provincial Police have charged Francoise Séguin, a 97-year-old woman from Ottawa, with three counts of indecent assault related to her involvement in residential and day schools in Northern Ontario during the 1960s and 1970s.

This comes after a report to the police about the incident late last year. According to reports, Séguin was involved in sexual assaults that occurred at the residential and day schools in Fort Albany and Mooseonee in Northern Ontario, as well as a prison in Sudbury.

Records reviewed by CBC reporters show that Séguin was a nun who worked at the Santa Ana residential school in Fort Albany from 1958 to 1968.

According to the Truth and Reconciliation Center, Santa Ana residential school was closed in 1976 and had about 280 students in the 1960s and 1970s. Five former staff members of the school have been charged with criminal offenses in the past. Authorities plan to use ground-penetrating radar to search the Santa Ana school site this winter.

The Bishop Hall residential school in Mooseonee had more than two hundred students before it closed in 1964. No one has been charged from that school.

Séguin is scheduled to appear in court in December.
