Ontario High School Courses Overview
The high school curriculum in Ontario operates on a credit system. Students earn credits by completing courses across various subjects, allowing them to blend required learning with personal interests. This flexibility is a key feature of the Ontario Secondary School Diploma (OSSD) program, which aims to provide a well-rounded education tailored to diverse learning styles and future aspirations.
To understand course offerings and prerequisites, the school’s course calendar serves as an essential resource. Familiarizing yourself with this system is crucial for effectively planning a secondary school program. In the following sections, we will explore the types of courses available, the credit system, and the requirements for graduating high school.
What Are Ontario High School Courses?
Ontario high school courses are the building blocks of your child’s secondary school education, following the Ontario curriculum set by the Ministry of Education. Each subject area has specific learning goals, and passing a course earns your child a credit toward their high school diploma. There are two main types: compulsory courses, which cover core subjects like English, math, and science, and elective courses, which let students explore interests such as business, technology, arts, or social sciences. This combination allows students to create a personalized learning plan, helping them prepare for future education, careers, or other pathways after graduation.
The Ontario Credit System
The Ontario credit system is straightforward: to graduate, students must earn a total of 30 credits. One credit is typically equivalent to a course that involves 110 hours of instruction. The school board oversees the implementation of this system, ensuring standards are met.
The number of compulsory credits and optional credits (also known as electives) depends on when your child started Grade 9. This distinction is important for academic planning. Students can also earn an additional credit by taking the Ontario Secondary School Literacy Course if they are eligible.
Here is a simple breakdown of the credit requirements:
| Student Group | Compulsory Credits | Optional Credits | Total Credits |
|---|---|---|---|
| Started Grade 9 in 2023 or earlier | 18 | 12 | 30 |
| Started Grade 9 in 2024 or later | 17 | 13 | 30 |
Additional OSSD Requirements
Besides earning 30 credits, students must meet other key OSSD requirements to graduate. These help students build literacy skills and encourage community involvement. A main requirement is the literacy graduation requirement, usually met by passing the Ontario Secondary School Literacy Test (OSSLT). If a student does not pass, they can take the Ontario Secondary School Literacy Course (OLC4O) instead.
Students must also complete:
- 40 hours of community involvement activities: Encourages civic responsibility and helping the community.
- Two online learning credits: Prepares students for learning and working in a digital world. Parents or guardians can request an exemption.
These requirements support student success after graduation.
Compulsory Courses in Ontario High Schools
Compulsory courses are the ones that all high school students have to take. These are not optional. To meet the compulsory credit requirement for graduation, every student must pass a set number of these classes. Compulsory courses make sure all students in the province get the same basic skills and information.
Finishing these graduation requirements helps your child be ready for many choices after high school. Let’s look at which compulsory credit subjects your child will have to take.
Core Academic Subjects
Core academic subjects are very important for the Ontario high school system. These courses help every student improve in reading, math, and science.
The compulsory English course is needed every year, giving students four credits once they finish high school. For math, students need three credits, and at least one must be taken in Grade 11 or 12. Science classes give students two credits. Every student must also earn one credit from health and physical education.
Other compulsory credits for high school in Ontario are:
- 1 credit in Canadian History (Grade 10)
- 1 credit in Canadian Geography (Grade 9)
- 0.5 credit in Civics and Citizenship
- 0.5 credit in Career Studies
Language and Arts Requirements
- Ontario students must earn one credit in French as a second language; alternatively, a native languages course can count if taken in elementary school instead of French.
- The compulsory English course is required, and students may also choose an international language as an elective. For the arts, one credit is needed, which can be earned in music, drama, or visual arts.
- The Grade 9 Expressions of First Nations, Métis, and Inuit Cultures course uniquely fulfills the arts credit, allowing students to explore Indigenous perspectives while meeting graduation requirements.
Understanding Course Codes
- Ontario high school courses use codes like “ENG4U” to quickly show key details.
- The first three letters/numbers reveal the subject (e.g., “ENG” for English), the fourth indicates the grade (1 for Grade 9, 2 for Grade 10, etc.), and the last letter shows the course type: “U” for university prep, “C” for college prep.
- For a full explanation, check the school’s course calendar it lists all courses and codes, helping students and parents choose the best options for their academic goals.

Elective credits give your child a way to make their high school time special just for them. These 12 or 13 optional credits let students pick classes that fit what they like and what jobs they might want later. Your child can try out all sorts of things, like technological education, business studies, and the arts. The choices are big, so there is something for everyone.
These classes are not only fun. They also give students the chance to learn new skills that are very useful, too. Some electives, like cooperative education, even let students get hands-on experience. This is a lot like what they do in community involvement activities, where people go out and help in real places. Now, let’s take a look at some top elective categories you can choose from.

Grades 11–12 (Pathway Years)

Choosing the Right Ontario High School Courses

You do not have to do this by yourself. The school offers plenty of help. There is a detailed course calendar you and your child can look at to see all the class choices. The guidance counselor is there to give advice and answer questions. Together, these can help you make a plan that fits your child’s goals.
Aligning Courses with Future Goals
The best way to plan high school courses is to start with your child’s future goals and work backward. If university is the goal, find out early which programs interest your child ideally by Grade 10. Each university lists admission requirements for programs on their websites. For example, engineering needs certain math and science courses, while humanities may need specific English credits. Use this information, or ask a guidance counsellor for help. Choosing courses that match these requirements ensures your child is prepared to apply to their preferred programs. Here’s what you need to do:
- Research university program requirements.
- Pick the right Grade 11 and 12 courses.
- Make sure all graduation requirement steps are completed along the way.
Guidance and Academic Planning
Your child’s guidance counselor is the best resource for academic planning, offering personalized advice based on the Ontario curriculum and your child’s goals. Make use of the following:
- Regular Meetings: Schedule meetings with the guidance counselor to discuss your child’s academic plan, review course options, and clarify questions about graduation and post-secondary pathways.
- School Tools: Take advantage of course selection nights and online planning tools provided by the school to make informed choices.
- Special Guidance: For mature students, ask the counselor about prior learning assessment and credits for previous experiences to support graduation requirements.
