Question 1

What's the best online high school in Ontario?

Accepted Answer

It depends on what you're optimizing for. Cheapest legitimate credits: TVO ILC (~$40/course for most Ontario residents). Best established self-paced private school: Ontario Virtual School ($499–$574/credit). Fastest completion with modern, interactive lessons and portfolio output: Units ($1,000/credit, learning itself is free). All of them put real OSSD credits on your Ontario Student Transcript.

Question 2

Are online OSSD credits accepted by universities?

Accepted Answer

Yes. Credits from any Ministry-inspected school — public or private — appear identically on your Ontario Student Transcript and are accepted by every Canadian university. Universities see the course code, grade, and issuing school, exactly as they would for a traditional high school.

Question 3

What's the cheapest way to earn an OSSD credit online?

Accepted Answer

TVO ILC, at roughly $40 per course for most Ontario residents thanks to government subsidy. The trade-off is minimal support and slow feedback — many students take six months or more per course, and completion rates suffer. If your goal is a credit this semester, a private school's support usually pays for itself.

Question 4

What's the fastest way to earn an OSSD credit online?

Accepted Answer

Mastery-based programs are structurally faster because you skip what you can already prove and never wait days for grading. Units is designed for 4–8 weeks per credit. Traditional self-paced schools allow fast completion in theory, but text-based lessons and teacher-graded turnaround make 3–6 months typical in practice.

Question 5

Can I mix schools — take one course online and the rest at my day school?

Accepted Answer

Yes. OSSD credits stack onto one Ontario Student Transcript regardless of which inspected school issued them. Taking one or two credits online to get ahead, free up a timetable slot, or replace a weak grade is the most common way students use every school on this list.

Question 6

Is this ranking biased? You make Units.

Accepted Answer

We make Units, and it's ranked first for the specific student it's built for — someone who values speed, feedback, and portfolio output over price. If you want the cheapest credit, we tell you to go to ILC. If you want the biggest catalogue at a low price, we point you to OVS. Every factual claim on this page is checked against the schools' own published pricing and policies, with a last-verified date, and we correct errors within a day.
