It also formerly housed St. Mary's Primary School, a Catholic elementary which opened in 1908. It was previously known as St. Mary's School and St. Mary's Elementary School. Circa 2008 its enrollment was about 266; this fell to 133 in 2018. The school closed that year. Principal Michael O'Brien stated that the state of the physical plant was one factor in the school's closure. The school did not have an elevator. In addition to the physical plant factor, the diocese also no longer wished to cover the school's expenses. In 2018 it was $500,000 in debt for salaries and other items, and it also had a $1.5 million debt for 2006-2014 medical/dental insurance costs.
