My daughter took a grade 9 geography course and had a wonderful experience! Her teacher was very responsive and the course material was excellent and just the right amount. We will definitely be coming back to this online school in the future.

Supported by Ontario Certified Teachers
Any high school student in Ontario, across Canada, or abroad can enroll at Ontario eSecondary School (OES), a Ministry-inspected online high school (BSID #667186). There is no entrance exam. You register online, provide your most recent report card or transcript, and can start your course within 1–2 business days.
Yes. OES is inspected by the Ontario Ministry of Education and authorized to grant OSSD credits. Credits appear on your official Ontario transcript and are accepted by universities and colleges across Ontario, British Columbia, the rest of Canada, and internationally. OES students have been accepted by the University of Toronto, the University of Waterloo, and Toronto Metropolitan University.
Yes. Students retake Grade 11 and 12 courses such as ENG4U, MHF4U, MCV4U, and SCH4U to raise a previous mark. OES upgrade courses have a focused workload designed for students who have already seen the material, and the new grade appears on your Ontario transcript for university and college applications.
Yes. Credits earned at any Ontario school transfer through your Ontario Student Record (OSR), and credits from other provinces or countries can be assessed for equivalency through Prior Learning Assessment and Recognition (PLAR). A guidance counsellor reviews your transcript and confirms exactly which credits you still need for your OSSD.
OES courses are 100% online and self-paced. Each 110-hour credit course includes all materials, instruction and assessment by an Ontario Certified Teacher, free 24/7 on-demand tutoring, and a 24-hour teacher response time by email. Final exams are proctored fully online at no extra charge — included in the course fee. Under Ontario’s updated 2026–27 assessment rules, final marks in Grade 11 and 12 English, math and science courses combine coursework (65%), a mandatory written final exam (25%), and attendance and participation (10%), in accordance with Growing Success. Most students finish a course in 4–16 weeks, and the credit is then added to your official record.
