Sister Andrea is the School Archivist, former School Librarian. She may have been there when you were in school. She is a beautiful little nun, pleasant and obliging. There is a book for each year that the school was open. What she has done was a tremendous amount of work.
She took me and my daughter on a tour of the building and invited us to have lunch. I even met the teacher who taught the choir when I was there in 1953.
The former school is now the Motherhouse. The sisters go there to retire and the building is used for various other things.
If you are interested you can contact Sister Andrea, St. Joseph's College Alumnae, Main St. West, North Bay, Ontario. I'm sorry, I do not know the number of the street.
Hope this info is of help to you.
