Biology
Biology is York's longest-established science program and studies living things from molecules to ecosystems. Students can explore many areas of life science or specialize, and develop analytical and lab skills through research projects and laboratory work. Graduates go on to fields such as pharmaceuticals, health care and conservation, and an international iBSc with study abroad is also offered.

Tuition Information
York's approximate 2026-27 tuition for a full-time student in most Arts and Sciences programs: about CAD 6,200 a year for domestic students and about CAD 40,000 for international students. Fees are based on 30 credits (five full courses). Supplementary fees (student levies, athletics, health and counselling) are extra, typically about CAD 40-50 per credit, and international students pay about CAD 1,151 a year for UHIP health insurance and the student health plan. These are estimates for a full course load; actual fees depend on the courses taken. 2027-28 fees are not yet published.
