Studying Nursing in Ontario
You can’t always apply to nursing directly. Some universities admit you straight into it; others admit you into a broad first-year category and you choose nursing 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 nursing later
University of Toronto — St. George
Apply to Bachelor of Science in Nursing (second-entry, Lawrence Bloomberg Faculty of Nursing)
You choose nursing you apply during the second year of another university degree.
You cannot apply to U of T nursing from Grade 12 — there is no OUAC code for a high school applicant and no nursing program page in U of T's undergraduate finder. The BScN is second-entry: at least two years of university equal to 10.0 U of T credits, minimum 4.0 of them above first-year level, and a B average (about 75%) in your most recent 5.0 credits.

Apply to not offered at UTM
UTM has no nursing program — confirmed absent from the full A-Z listing. U of T nursing (Bloomberg) is at St. George and is second-entry only, requiring prior university study, so no Ontario Grade 12 student can apply to U of T nursing directly.

Apply straight to nursing
Nursing - Direct Entry BScN (ENW)
Western
ENW is the 3.5-year Direct Entry BScN and the only code for Grade 12 applicants. The other nursing codes on the OUAC list — ENS, ENA and ENB — are Compressed Time Frame streams for people who already have two years of university credit or are Registered Practical Nurses; do not pick those from high school. ENW requires a minimum 70% in each of ENG4U, SBI4U and SCH4U, plus 70% in one math (Grade 11 MCF3M or MCR3U is acceptable, otherwise a 4U math).
Queen's
Verified verbatim: "English 4U with a minimum grade of 75%, Biology 4U, Chemistry 4U, plus any 4U Mathematics course." Note it is ANY 4U math, not Calculus. Nursing is its own school — you cannot transfer in later from Health Sciences or Life Sciences, so it must be on your OUAC application now. A Supplementary Application is required for the four-year BNSc (due Feb 15); applicants to the AST Nursing program are exempt.
Nursing I (McMaster University Site)
McMaster
Genuine direct entry, and a supplementary application is required — for Nursing that means CASPer, which you book a testing date for yourself. The catch students miss: the McMaster site and the Mohawk College site are separate OUAC choices with separate competition. You can apply to both, both graduate you with a McMaster BScN, and there is no transferring between sites once you start.
