What it is	You study the chemistry of living things — how molecules work in cells and bodies, and how drugs and toxins affect them. This program combines chemistry and biology more deeply than a general life sciences program, with added focus on how substances interact with organisms. It suits students curious about medicine, pharmacy, drug development, or toxicology who want a stronger chemical foundation than biology alone provides.	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.	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.

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.
