Venetsiya is a graduate of Ontario eSecondary School. She was an international student that earned her Ontario Secondary School Diploma through OES and was able to apply to study medicine as a result. OES is a great option for international students who need to earn credits from a Canadian institution or an Ontario accredited institution in order to be considered for some post-secondary studies. Don’t just take it from us though, hear it from Venetsiya!

  • It was a great experience with OES High School and the teacher, Mr. Reel, as well as the administrator, Mara, are very kind, understanding, and responded to all of my emails super fast! I highly recommended OES to all students who need any high school credits! Thank you so much OES, I am very happy with my involvement with you!

    I had an incredible experience at Ontario eSecondary School while taking the MDM4U credit with Mr. Reel. His teaching made learning Data Management both enjoyable and understandable. Also, Mara's exceptional support during and after the enrollment process made everything quick and seamless. The kindness and support shown by everyone at OES made learning so much more easy and fun!

    My experience with OES is summarised in one word "Phenomenal". I highly recommend this institution to anyone who would like to improve or expand your educational requirements. Both the teachers and administration are professionals and provide top-notch services with outstanding quality . The programs allows the flexibility to complete at your own pace, which is important.
    Thanks OES!!

    Ontario eSecondary School was such a great opportunity for me and I really enjoyed the work that I did with them. Their courses are well structured, ensuring student success and understanding. I felt that I always had someone to ask when I had questions or concerns and my teachers were extremely quick with their responses. Since I was able to complete all my course work on my own, I learned a lot about time management and was able to meet my program requirements on time. I would 100% recommend courses from this school for anyone looking to upgrade their highschool course requirements or finish highschool. Good luck!

  • 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.

    As this program offers, it's a way for anyone to obtain credits through an method with 24/7 assistance with an on-demand, unlimited and fully online tutoring service. Fast and accessible as you work at your own pace to fit your schedule.

    I was given a yearly time period to complete a course and finished within 3-4 months. Your assigned teacher isn't obligated to delegate you, but just like any field of learning. There're expectations and deadlines.

    My son recently completed Challenge and Change, a grade 12 social science course from overseas. His experience from registration, through to course work, exam competition and facilitating his grade to his transcript was exceptional, responsive, and professional. His teacher Mara was more engaged than many of his previous in-person teachers. Thank you!!!

    Amazing school experience where the teachers are there to help facilitate learning and excellence, not to put their students down, like many teachers do. I re-took grade 11 university functions and received a much better education and final grade than my experience in public schooling in Southern Ontario. I would highly recommend this if you are organized and can meet your own deadlines.

They do have a 24 hour tutors that can help you to explain at any time I like it I don’t know what to say more but it’s one of the best school.

    Thank you

    Ontario eSecondary School is by far the best online learning academy in Ontario. My teacher was very great as he was easily accessible, had very fast response times, and was extremely friendly. He even had the chance to do our live meeting on Thanksgiving Monday! The course content for the class I took was great, and will be very beneficial for post-secondary learning. It was amazing that they provided free online tutoring for students, that feature really stood out to me when selecting OES for this course. You will not regret taking a course here!
