Prerequisitesas published	Six 4U/M credits, including English (ENG4U) Advanced Functions (MHF4U) Two of Calculus and Vectors (MCV4U), Biology (SBI4U), Chemistry (SCH4U) or Physics (SPH4U). We recommend you take all 4 of these courses. A combined minimum 70% average in prerequisite math and science courses.	ENG4U MHF4U Some areas also require additional prerequisites, such as SCH4U and/or SBI4U and/or SPH4U Alternative Offers Because of the competitive nature of this program, you may receive an invitation after you apply for your application to be automatically reviewed for an alternative program, provided you are qualified and there is space.	ENG4U MCV4U MHF4 Science prerequisites (SPH4U or SBI4U) for specific disciplines are also required. SCH4U is recommended for specific disciplines.

What it is	Chemical biology is the study of how chemicals and molecules work inside living cells and organisms, blending chemistry and biology together. Unlike a straight chemistry or biology program, you focus specifically on the molecular level of life processes. The co-op option means you alternate between school terms and paid work terms at companies or research labs, giving you real experience in the field. This suits people who want hands-on workplace learning and are curious about both how molecules behave and how life functions.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.

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.
