Studying Microbiology in Ontario

You can’t always apply to microbiology directly. Some universities admit you straight into it; others admit you into a broad first-year category and you choose microbiology later. That difference is why searching for a major by name can make it look like a university doesn’t offer it.

Apply broad, choose microbiology later

Apply straight to microbiology

  • Life Sciences and Biochemistry (QL)

    Queen's

    Don't search OUAC for a "Microbiology" code — there isn't one. Queen's undergraduate Microbiology and Immunology only exists as a graduate department name; the university's own calendar states admission to the old grad program "Microbiology and Immunology" stopped in 2014 and it folded into Biomedical and Molecular Sciences. For a 17-year-old wanting microbiology, the real Grade 12 route is QL (Life Sciences and Biochemistry), entering as one cohort in first year, splitting into the Life Sciences plan in spring, and later choosing the Biomedical Discovery sub-plan (which explicitly lists Microbiology as an option) once in the Specialization plan — access to some 4th-year specialized courses also requires keeping a cumulative GPA of 2.50.

Read off each university’s own admissions pages, and covering the seven campuses Ontario students apply to most. Entry structures change — confirm with the university before you build a timetable around one. Search all programs.
