School at a Glance
Sacred Heart School of Montreal was founded in 1861 as the first Sacred Heart school in Montreal, part of the Society of the Sacred Heart founded by Saint Madeleine Sophie Barat. It belongs to a worldwide network of roughly 150 Sacred Heart schools. The current campus at 3635 Atwater Ave has been the school’s home since 1928. The school serves girls in two bands: Grades 7 to 11 (Secondary I to V) and a separate Grade 12 program, with day and boarding options in both.
Since September 2024 the school has operated as a fully independent school: certificates of eligibility are no longer required, so applicants of any linguistic background or immigration status may apply. The average class size is 18, and the school describes its central Montreal location as a practical base for experiencing the city.
Programs: Grades 7 to 11 and the Grade 12 Pathway
For Grades 7 to 11, Sacred Heart School of Montreal leads students toward the Ministère de l’Éducation du Québec (MEQ) secondary school diploma. French is taught at three levels, from second language to mother tongue, and students completing mother-tongue English and French graduate with a bilingual certificate; Social Sciences and Art are taught in French in Grades 7 and 8. Spanish is mandatory in Secondary I to III and an elective in IV and V. There is an accelerated math track for students who want to reach Calculus in Grade 11, and the school offers AP courses. Community service is part of the Sacred Heart certificate: students must complete 40 hours by April of Grade 11, with half completed before entering Grade 11, including during the summer.
The Grade 12 program is a distinct pathway: delivered with Northern Pre University (powered by OVS, the Ontario Virtual School accredited by the Ontario Ministry of Education), it leads to the Ontario Secondary School Diploma (OSSD), an internationally recognised credential. Classes run Monday to Friday, roughly 8:30 a.m. to 12:00 p.m., combining online materials with in-person instruction and feedback from Sacred Heart teachers. Each student is paired with a community mentor, completes 10 hours of community service, and joins a health and wellness program. The school also cites a new five-year partnership with Concordia University offering Grade 12 students accelerated admissions and prioritised application processing.
Entry Requirements for International Students
For Grades 7 to 11, Sacred Heart School of Montreal lists these requirements for international applicants: legal, medical and financial documentation; proof of English proficiency through a standardised test (Duolingo, IELTS or TOEFL) for applicants whose mother tongue is not English; academic transcripts from previous schools with English translation; letters of recommendation from teachers or administrators; entrance tests in English and Mathematics; and an interview, in person or by video conference. A campus tour in Mandarin is available.
The Grade 12 international requirements are more specific about English scores: TOEFL iBT 90 or paper-based 500, IELTS in the 6-6.5 range, or a minimum CAEL score of 70. Immigration documents must be provided, and additional curriculum details from the current school may be requested. Domestic applicants for Grade 12 face no entrance exams; admission is decided on transcripts, a confidential school report, a student profile and an interview, with prerequisite Grade 11 science-option math for the Commerce and Science streams, and Physics and Chemistry also required for Science.

Boarding and Campus Life
Sacred Heart School of Montreal offers 5-day boarding (for families living nearby who want weekends at home) and 7-day boarding (for students from farther away, including international students) across both the Grades 7 to 11 and Grade 12 programs. The boarding wing features double-occupancy rooms with a desk, ergonomic chair and storage, laundry facilities, two common rooms, and meals covering breakfast, dinner and snacks; full-time staff live on site. Weekends include cultural outings, arts and athletics, making use of what central Montreal offers.
Beyond boarding, campus life spans arts, athletics, food services, transportation, clubs and after-school activities, and community service. Uniforms are required in Grades 7 to 11 (dress uniform, casual uniform and P.E. uniform); Grade 12 follows a business-casual dress code. For international families, boarding packages accommodation, supervision and weekend programming into one arrangement, which simplifies planning compared with arranging housing separately.
How to Apply and Where Support Comes In
Applications open with a single step: complete the online application form for the relevant band (Grades 7 to 11 and Grade 12 use separate forms), then follow the website’s instructions for the next steps. Sacred Heart School of Montreal is currently accepting applications for the 2026-2027 school year and does not publish a single application deadline, so completing materials early matters for year-level places.
