Compare / Units vs. OVS
Units vs. Ontario Virtual School
Both issue real OSSD credits. OVS is the established, lower-cost self-paced school. Units is the mastery-based platform built for finishing in weeks with portfolio work to show for it. Here's the honest breakdown.
Yes, we make Units — so we wrote this the way we'd want a competitor to write about us. Facts last verified August 2026.
Choose Units
- You want the credit in 4–8 weeks, not months
- You learn better from interactive lessons than PDFs and videos
- You want a 24/7 AI coach and instant feedback
- You want work you can publish and put in applications
- You'd rather be taught to use AI well than told not to use it
Choose OVS
- You want the lowest private-school price ($499–$574/credit)
- You need a niche elective from a large catalogue
- You prefer a traditional course format with a final exam
- You want a school with a 15-year track record
- You have up to a year and don't need to move fast
