Best Computer Science Programs in Canada (2026)
Waterloo, UBC, and UofT lead Canada's computer science rankings on verified outcomes. Here's what the real admission bar looks like, and what separates admitted students from equally smart applicants.
Jump to
Computer Science (CS) is where Canada's grade inflation meets its hardest admissions math. Thousands of applicants show up with 95-plus averages, and the top programs still turn most of them away.
If you're aiming for Waterloo, UBC, or UofT, you need to know two things: what the real bar is and what separates the admitted students from the equally smart ones who weren't.
This guide covers both, with verified data instead of forum rumours.
Where These Rankings Come From
These rankings come from The Maple List, AdmissionPrep's Canadian school finder. It takes every university with a recognized strength in computer science and orders them by verified school-wide outcomes: first-year retention, graduation rate, and graduate employment, each cited to an official source.
One honest caveat, straight from the methodology: Canada doesn't publish program-level outcome data yet. Maple inherits each school's verified figures and labels them as such, rather than inventing per-program numbers. No school paid to appear.
Here's the 2026 cohort.
The Top Computer Science Universities (2026)
| Rank | University | CS Competitive Range | School-Wide Entering Average | Outcome Score | Maple Grade |
|---|---|---|---|---|---|
| 1 | University of Waterloo | 90-95% | ~90% (estimate) | 89 | A |
| 2 | University of British Columbia | Not published | 90% | 88 | A |
| 3 | University of Toronto | 90-93% | ~91% (estimate) | 76 | B |
Data via The Maple List, June 2026. CS competitive ranges are the bands the schools publish for the program itself. UBC publishes no admission average for Computer Science and Maple does not estimate one, so that cell stays honest rather than guessed. School-wide averages marked with ~ are Maple List estimates.
We kept this list deliberately short: this cohort includes only universities with recognized CS strength and sourced outcomes. Strong programs also run at SFU, Alberta, Calgary, TMU, and York. You can browse every verified CS program on The Maple List's computer science page.
Now, the top three in detail.
1. University of Waterloo
Waterloo CS is the most famous technology pipeline in the country, built on the world's largest co-op program. The school's verified numbers back the reputation: 94.1 percent first-year retention and 96.3 percent graduate employment, both cited to official sources on Waterloo's Maple List report card.
What does it take to get in? The Waterloo CS program page lays out the verified requirements: six Grade 12 U or M courses including Advanced Functions, Calculus and Vectors, and English, with Grade 11 Computer Science recommended. The competitive range sits around 90 to 95 percent and varies by year.
But grades alone won't do it. Waterloo requires the Admission Information Form (AIF), and students are strongly encouraged to participate in math contests (the CCC, CSMC, and Euclid). Contest participation is also required to be eligible for Math entrance scholarships. The Waterloo AIF guide breaks down how to make that form count.
2. University of British Columbia
UBC pairs a documented 90 percent entering average with the strongest program-score showing on The Maple List: UBC's computing programs, including Computer Science, hold the top spots among all 76 verified CS programs in the country.
One honest gap: UBC publishes no separate admission average for Computer Science, and Maple doesn't invent one. Treat the school-wide 90 percent as a floor rather than a target, because competitive years run well above it.
UBC admits through the Personal Profile: written responses about your choices, experiences, and impact. It rewards students who can tell a specific story. The UBC admissions guide covers the Personal Profile in detail.
3. University of Toronto
UofT CS gives you Canada's top-ranked university, a downtown Toronto tech ecosystem, and research depth few schools match. The university-wide entering average sits around 91 percent, but CS runs its own band. The Maple List puts the CS competitive range at 90 to 93 percent, and our UofT guide tells scholars to aim for 93 if they want room to spare.
Requirements and structure vary by campus and stream, so read the UofT CS page on The Maple List alongside the complete UofT admissions guide.
Want the career-first view instead? The Maple List also ranks schools by the become-a-software-developer pathway, which reframes the same data around the job you actually want.

Computer Science or Software Engineering?
Applicants mix these up constantly, and the difference matters.
Computer science at Waterloo lives in the Faculty of Mathematics. It's theory-rich, flexible, and pairs with co-op. Software engineering is a separate, direct-entry engineering program with its own admission process and a more structured curriculum.
Which should you choose? Here's the short version: if you want maximum flexibility and depth in algorithms and math, choose CS. If you want an engineering credential and a locked-in project sequence, look at software engineering. Many students apply to both, and that's a legitimate strategy. The guide on how to become an engineer in Canada maps the engineering side.
How to Actually Get In
Every serious CS applicant has high marks in math. Here's what makes the admitted ones stand out.
1. Write math and computing contests. The CCC and Euclid give admissions committees a standardized signal that cuts through grade inflation. At Waterloo, contests also unlock scholarship eligibility. Write them in Grade 11 for practice and Grade 12 for real.
2. Build something and ship it. A published app, a game, an open-source contribution. One finished project beats a long list of tutorials, because it proves you can push through the unglamorous last 20 percent.
3. Treat the AIF and Personal Profile as essays, not forms. Use the STAR structure: Situation, Task, Action, Result. "Built a scheduling app for my school's tutoring club, now used by 40 students weekly" lands harder than "passionate about coding."
4. Show sustained curiosity. Hackathons, robotics, a part-time coding job. Depth over years, as early as Grade 9, reads as genuine. A Grade 12 sprint reads as strategic.
Pro Tip: Keep a simple log of every project, contest, and role starting in Grade 11: what you did, what changed because of it, and one number that proves it. Application season becomes assembly instead of archaeology.
A Note for Parents
CS admissions have tightened faster than almost any field, and the published minimums badly understate the real bar (this guide to what average you need for university in Canada shows the same gap across every school). A student with an 88 percent average and no contests or projects is not competitive at the top three, even though every program's website technically says they qualify.
The good news: the extras that matter (contests, projects, the AIF) are learnable skills with a long runway. Grade 11 is the year to line them up.
If you'd like an honest read on where your child stands, AdmissionPrep's Assessment does exactly that. Our Educators take a limited number of scholars each year, so the program waitlist is worth joining early.
FAQ: Computer Science in Canada
What is the best computer science program in Canada?
Waterloo, UBC, and UofT lead The Maple List's 2026 outcome-based rankings for computer science. Waterloo ranks first on verified school-wide outcomes among CS-strength universities, and its co-op program is the largest in the world. UBC's computing programs hold the top program scores nationally.
What average do you need for computer science in Canada?
Waterloo publishes a competitive range of 90 to 95 percent for CS, and UofT's sits at 90 to 93 percent. UBC publishes no CS-specific average, but its school-wide figure is 90 percent and competitive years run higher. Published minimums are lower, but admitted students cluster at the top. Strong supplementary materials and contest results matter alongside grades.
Does Waterloo CS require the Euclid contest?
No contest is strictly required for admission, but Waterloo strongly encourages the CCC, CSMC, and Euclid, and contest participation is required to be eligible for Math entrance scholarships. A strong contest score is one of the clearest ways to stand out.
Is computer science harder to get into than engineering?
At top schools, CS admission averages now rival or exceed those of most engineering programs. Software engineering at Waterloo is comparably selective. Both fields expect evidence beyond grades, like contests and projects.
What courses do you need for computer science?
For Waterloo CS: six Grade 12 U/M courses including Advanced Functions, Calculus and Vectors, and English, with Grade 11 Computer Science recommended. Most Canadian CS programs require senior math through calculus; check each program's verified requirements on The Maple List.
Can I get into CS with no coding experience?
Yes. Universities teach programming from scratch, and admissions committees know not every school offers CS courses. But you'll be competing against applicants with projects and contests, so build evidence of interest however your school allows.
Your Move
Waterloo received over 50,000 applications in 2023. Fifty thousand. CS takes a giant share of them, and every serious applicant arrives with marks in the 90s.
The admitted ones bring more: contest scores, shipped projects, and an AIF or Personal Profile that proves the interest is real.
AdmissionPrep works with ambitious scholars targeting exactly these programs. Take the Program Assessment to see where your profile stands today. Then apply to the program waitlist, because our Educators take on a limited number of scholars each year and CS families book early.
The next wave of Canadian founders and engineers is sitting in Grade 11 classrooms right now. Do the work, and maybe we'll see you on campus in Waterloo, Vancouver, or Toronto soon.
