What it is	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	Honours Integrated Science teaches you how different sciences connect and overlap rather than studying them in separate boxes. You'll take courses across biology, chemistry, physics, psychology, and environmental studies, learning how they relate to real problems instead of treating each discipline independently. This suits students who want a flexible foundation in science and aren't certain yet which single specialization they'll pursue.	This program combines foundational study in mathematics with hands-on work in chemistry, physics, astronomy, geology, and related fields. You'll take core courses in pure and applied mathematics alongside lab work and theory in the physical sciences, giving you breadth rather than specialization in a single discipline. It suits students drawn to quantitative problem-solving across multiple scientific areas who want flexibility to explore before committing to a specific path.	Nanotechnology Engineering is the study of designing and building materials and devices at the molecular and atomic scale, combining chemistry, physics, materials science, and engineering. Unlike a general engineering program, this one requires you to complete mandatory work terms alongside your studies, alternating between classroom and industry jobs so you graduate with significant hands-on experience. It suits students strong in math and sciences who want practical engineering experience and are interested in how materials behave at extremely small scales.
