St. Josaphat Catholic School is the first of three Eastern-Rite schools to have been established in Toronto. Through the strong beliefs of Bishop Isidore Borecky that a need existed within the community to educate its children on a sound spiritual base, plans got underway to raise funds for a private parochial school. Much effort was devoted by the community to raising funds, and in 1961 the first six-classroom school was built. The school was initially administered and staffed by the Sister Servants of Mary Immaculate. Msgr. Filevich, campaigned heavily within the Ukrainian Catholic community to convince parents to send their children to the school.

In 1963, the Metropolitan Separate School Board (now Toronto Catholic District School Board) assumed partial responsibility for the school. Over the next few years, the community continued to raise funds and purchased three school buses in order to allow more families access to this unique school. Eventually, TCDSB assumed complete responsibility for the school. St. Josaphat Catholic School now serves students and parents from all over the Toronto area, who want the opportunity of an education that fosters academic and spiritual development within the Eastern-Rite tradition.
