• We will issue conditional offers of admission starting at the end of November 2026 for fall 2027 to highly qualified applicants.
• We will continue to issue offers of admission on a weekly basis to qualified applicants until the end of June. Please note that the requirements listed for these programs are minimum requirements only and are subject to change. Meeting the minimum average does not guarantee admission.
• Early offers are based on the average of five 3U/M grades or a combination of 3U/M and available 4U/M final grades. No offers are sent before February for Acting (BFA), Music (BMus) and Music and Science (5-year double degree).
• From February to April, we calculate the average using the top 6 final 4U/M or 3U/M marks, including prerequisites. A minimum of two 4U/M grades are used for this round of offers.
• In our last round of offers in May and June, we calculate the average using the top 6 final or interim 4U/M, including prerequisites. Refusals and alternate offers are only issued during this round.
• All offers of admission are conditional. You must successfully complete a minimum of 6 eligible 4U/M courses, including prerequisite subjects of the requested program, obtain a specific admission average and present proof of your Ontario Secondary School Diploma or the equivalent before September.
• Details regarding offers of residence and scholarships will be sent with the offer of admission. You must respond before the date indicated in your offer of admission.

Applicants assessed on the full IB Diploma for the named English-language undergraduate entry route; Ontario OSSD assessment remains separate

• English A at SL/HL, plus Mathematics Analysis and Approaches SL/HL or Applications and Interpretation HL. Applications and Interpretation SL is not accepted for this program.
• Applicants who completed English B rather than English A must provide an English language proficiency test.

IB applicants; exact degree subjects and published point thresholds remain separately held

• Complete or be completing the full IB Diploma programme and meet the chosen degree’s requirements. The published six-subject rule states at least three Standard Level and three Higher Level subjects, including the prerequisites. This packet does not decide an unlisted subject combination.
• An individual IB certificate alone is insufficient for admission; applicants must hold or be completing a recognized secondary-school diploma or equivalent. Programme-specific subject and score requirements stay unchanged.

Applicants applying with Ontario secondary-school or Québec CEGEP studies

• Ontario secondary-school transcripts are transmitted automatically through OUAC. Official CEGEP transcripts are also transmitted through OUAC only when the applicant supplies the12-digit Québec CEGEP permanent code; without it, the application cannot be assessed.
• Other requested documents are uploaded through uoDoc in uoZone. The personalized Admission file checklist controls each dossier. This reporting rule does not establish CEGEP academic eligibility or remove programme-specific materials.

Prior uOttawa/Saint Paul students, readmission applicants and the listed special application situations

• Most direct-entry undergraduate applications use OUAC. The current application page instead directs prior University of Ottawa or Saint Paul University students, applicants readmitted after required withdrawal and improved academic standing, Spring–Summer applicants, and applicants to institutional partnerships outside Canada to the University’s own undergraduate admission form.
• This identifies the correct application channel. Academic readmission, transfer-credit and programme-access decisions remain subject to their separate category rules; no admission eligibility is inferred from access to the form.
