In the summer of 2018, the renovation of the closed General Vanier Intermediate School took place to include a separate grade 7-8 wing in St. Joseph due to area elementary schools switching to a K-6 program or being consolidated.

St. Joseph's offers courses in accordance with Ontario's secondary school curriculum.

Students may be exempt from religion course, provided the parents notify the school in writing.

The Ontario Superior Court has ruled that student at a Catholic high school who is entitled to be excused from religious courses must also be excused, if they wish, from religious field trips and attending mass.

In addition, Specialist High Skill Majors (SHSM) are offered in Automotive, Business and Hospitality to provide students with certifications.
