McMaster Computer Science I
McMaster University
The published admission average for Computer Science I at McMaster University is 90% for September 2027 entry, under OUAC code MC. This program also requires a supplementary application.
Computer Science I is an introductory computer science program where you learn programming, algorithms, and core computational concepts. It differs from some other programs because it includes a mandatory co-op component, giving you paid work experience in tech roles alongside your studies. This program suits students who want hands-on industry experience early and are curious about whether computer science matches their strengths before committing to upper-year specializations.
Plain-English summary. The universities publish requirements but not an explanation of the program, so this one is written for you and checked against the official listing above. Read the university’s own page before you decide.

What this leads to
The picture for computer science as of 2026-08-17, not a description of this particular program.
Software engineers and developers design system hardware requirements and software applications, utilizing principles of computer science theory and practice and analysing processes to implement effective changes. Machine Learning Engineers design, build, train, and deploy ML models into production systems.
In its favour
- Entry-level graduates can earn around $98,000 on average, with significant upside as you gain experience
- You're training for the jobs actually hiring: cloud engineers, AI architects, data scientists, and ML developers are all on Robert Half Canada's high-growth list for 2026
- AI tools are now part of standard development workflows, not a niche skill—80% of engineering organizations rely on AI-assisted tools, so you'll learn this during your degree
Worth knowing
- Entry-level developer salaries in Ontario are around $63,000, not the $98,000 average—it takes years of experience to reach that figure
- Junior developers aged 22 to 25 saw a 20% drop in employment from late 2022 to mid-2025, showing the market for fresh grads is tightening
- Routine coding tasks are being automated: 40% of coding tasks are already being automated, and 45% more could be by 2030—you need to specialise in system design, architecture, or AI work to be competitive
- The fastest-growing roles (software engineering, cybersecurity, data science) take years of experience to break into; they're hard to fill precisely because they require depth, not entry-level hires
How AI is changing this work
AI is automating routine coding and testing but creating new roles in AI architecture, machine learning, and system design that require deeper problem-solving. Most of your degree will teach you to write code by hand, but that work is being done increasingly by AI tools—the real demand is for people who can design systems and integrate AI, not people who can code basic features. If you graduate with only traditional programming skills, you will compete directly against tools that are getting better every semester. The degree is still worth it, but only if you use it to specialise in something beyond "I can code," like data systems, cloud infrastructure, or AI integration.

Deadline reminders
This program needs a supplementary application, and those close before the January OUAC deadline — some in early December. We’ll email you before the ones that apply to Computer Science I.
We send your email address and the programs you’ve starred, so the reminders are the right ones. Your marks and your average are never sent — they stay in this browser. Deadline emails only, a week before and the day before each date, and every one has a link to stop them.
