What it is	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	Science One is a general first-year science program that lets you explore multiple science disciplines — biology, chemistry, physics, computer science, and others — before committing to a specific major. Unlike entering directly into a single science program, you take a broader range of foundational courses to discover which field best suits you. It works well for students who are interested in science but unsure which specialization to pursue.	Honours Science is a broad science degree where you choose your major from fields like biology, chemistry, environmental science, computer science, or archaeology. Unlike a general science program, an honours degree requires you to specialize in one subject and complete more advanced courses in that area. It suits students who want a strong grounding in science but haven't yet decided on one specific career path, or who want deeper knowledge in a particular field.	You study both business and science together as a combined honours degree, taking courses in fields like accounting, chemistry, computer science, or biology alongside business and economics. This differs from a straight business program because you develop scientific literacy and research skills, not just business knowledge. It suits people who want to understand how science and data work in real-world business contexts, or who haven't decided between these two interests yet.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
