Structure of the Ontario secondary system and the particularity of our school
In Ontario, the secondary school system is based on the completion of 30 credits, which students begin to accumulate in Grade 9 and continue through to Grade 12.
These credits, which include both compulsory and elective courses, are required to earn the Ontario Secondary School Diploma (OSSD). It is important to note that students in Grades 1 through 8 do not earn credits—these years are dedicated to building strong foundational skills, personal growth, and preparation for high school. Secondary education officially begins in Grade 9, marking the start of the credit-based academic path.
However, what sets École Louis Legrand apart in this educational landscape is its unique virtual model that supports students starting as early as Grade 1. Our school offers a comprehensive online learning journey from the early years through to the end of high school, allowing each student to thrive in a structured, consistent, and high-quality virtual environment throughout their entire academic career.
The specificity of the Ontario curriculum
The Ontario curriculum is recognized for its rigor, disciplinary breadth, and flexibility. It is not limited to homework or exams. It develops essential cross-curricular skills:
- Critical thinking and problem solving
- Clear and effective communication
- Civic responsibility and community engagement
- Integration of digital tools and 21st century skills
In addition to the required subjects, students have access to more than 200 optional courses, allowing them to specialize from high school onwards: in business, law, health, technology, the environment, aviation, the arts, etc.
The Ontario Secondary School Diploma (OSSD) also allows students to choose a personalized path and acquire expertise—a unique advantage in Ontario.
This is the framework that we scrupulously respect at the Louis Legrand School, with qualified teachers, up-to-date content, and active teaching.
