Studying Political Science in Ontario
You can’t always apply to political science directly. Some universities admit you straight into it; others admit you into a broad first-year category and you choose political science 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 political science later
Apply to Social Science (EO)
You choose political science at the end of first year, during Intent to Register in March.
Political Science shares code EO with Economics, Psychology, Sociology, History and the rest of Social Science — one OUAC choice covers all of them. Politics, Philosophy and Economics (PPE, both the Economics and the Politics-and-Philosophy concentrations) is administered by the Department of Political Science, and International Relations is jointly offered by Political Science and History — all inside Social Science.
https://welcome.uwo.ca/what-can-i-study/undergraduate-programs/social-science.htmlApply to Arts (QA)
You choose political science during Plan Selection in May at the end of first year.
Queen's calls it Political Studies, not Political Science — searching the wrong name makes it look like Queen's doesn't offer it. Confirmed as a department in the Arts and Science plan list. You apply to Arts, where only English 4U is a hard prerequisite, and request the plan in May of first year.
https://www.queensu.ca/artsci/programs-and-degreesApply to Social Sciences I
You choose political science at the end of first year.
Political Science is a Level 2 choice out of Social Sciences I, with co-op available (you apply to co-op at the end of first year too). If your interest is law and political theory, Justice, Political Philosophy and Law is a different program that sits in Humanities I and has its own required above-Level-I supplementary application.

Apply to Social Sciences
You choose political science at the end of first year.
Limited enrolment: the calendar requires 1.0 credit from POL101H1/POL106H1/POL107H1/POL109H1 with 65% in each (or 0.5 of those plus 0.5 from approved alternatives at 65%). Your first-year grades decide this, not your admission average. Only ENG4U is needed to apply.
https://future.utoronto.ca/program/political-science/University of Toronto — Mississauga
Apply to Social Sciences
You choose political science after first year (4.0 credits).
International Affairs, Economics & Political Science and History & Political Science all come through this same Social Sciences code, even though History on its own is Humanities (TMH).

Apply to Social Sciences & Humanities (OUAC TUD)
You choose political science end of first year, on ACORN.
Applies under Social Sciences & Humanities, OUAC TUD, which is missing from this dataset. Only Grade 12 English is required, mid 70s. No co-op option.
https://www.utsc.utoronto.ca/admissions/programs/political-scienceApply to Honours Arts
You choose political science at the end of first year.
"Apply to Honours Arts or Honours Arts and Business and choose Political Science as your major at the end of first year." Honours Arts requires only six Grade 12 U/M courses including any 4U English at 70%, with an admission average in the high 70s — the low course-specific bar is real; the competition is on the overall average. Mathematics of Data Management is recommended.
https://uwaterloo.ca/future-students/programs/political-scienceApply to Bachelor of Arts (BA) Honours (GK)
You choose political science on the OUAC application itself. Guelph's Honours BA majors all share code GK, and you name your major when you apply.
Political Science is a BA major under GK. Government, Economics and Management is a BComm with its own code, GBJ, if you want it with a business degree. Guelph's Honours BA is one OUAC code (GK) covering 26 majors, all published at 75-80%. You name the major on the application. Psychology and Criminal Justice are the exceptions — they have their own codes and higher ranges.
https://www.uoguelph.ca/explore-all-programs/Apply to Bachelor of Arts - Honours (CH)
You choose political science on the OUAC application, as your 'area of study' inside the Bachelor of Arts. Carleton's BA is one code (CH, 75%) for 31 majors. Leave the area blank and you are BA Undeclared; entrance requirements are the same for almost all BA majors, so changing later is a one-form request Carleton says takes 1-3 days.
Political Science is a BA major under CH. Public Affairs and Policy Management (CPX, 80-82%) and Global and International Studies (CGI, 75%) are separate direct-entry degrees for students who want policy or international work specifically. Carleton's Honours BA is a single OUAC code, CH, at 75%, covering 31 majors — you name the major on the application rather than applying to it separately. The 3-year non-honours BA is CA. Because entrance requirements are nearly identical across BA majors, switching after admission is a short online form.

Apply to Honours Bachelor of Arts (UZ)
You choose political science on the OUAC application, from a mandatory drop-down of 'Subjects of Major Interest' inside the Honours BA (UZ). If you are not sure, Laurier has a formal temporary designation that lets you take first-year courses in one or two areas and declare at the end of first year.
Political Science is a BA Subject of Major Interest under UZ; Global Studies is a separate BA major. Laurier's Honours BA is one OUAC code, UZ, published at mid-70s. You pick the major from a drop-down on the application — Laurier's own description is a 'mandatory drop-down picklist' of Subjects of Major Interest. Unusually, it also offers a temporary undeclared designation, so you can enter the BA without committing and declare at the end of first year.
https://www.wlu.ca/future-students/undergraduate/assets/resources/applying-to-laurier.htmlApply to not offered at Laurentian
Laurentian has no political science code among its 83 OUAC programmes, and its political science web page redirects to the generic programme list. Law and Justice (LLW, 70%) and Équité, diversité et droits de la personne (LDD, French) are the nearest.
https://laurentian.ca/undergraduate-programsApply to Bachelor of Arts (PA)
You choose political science on the application or after — the Bachelor of Arts (PA, 70% minimum) is a genuinely undeclared door, and you choose a major from the twenty inside it.
Political Science is a major inside the Bachelor of Arts. Nipissing admits to the Bachelor of Arts as one OUAC code, PA, at a 70% minimum, and nearly every arts major is chosen inside it rather than applied to separately. Only Criminal Justice (PAJ) and History with Orientation to a Master's (PAH, 80%, limited enrolment) have their own codes. Nipissing's own concurrent-education listings describe the BA entry as 'Undeclared'.
https://future.nipissingu.ca/programs/Apply to not offered at Trent Durham
No politics code at Durham; Political Studies (RPO) is at the Peterborough campus.

Apply straight to political science
Political Science (BA, iBA) (YUE)
Direct entry at low-to-mid 70s — one of York's lowest published ranges — co-op available. Global Political Studies (YBG) and Public Administration (YPG) are separate codes.
TMU's political science degree is Politics and Governance, direct entry at 70-75%, co-op available. Public Administration and Governance (SDF) is part-time only.
Direct entry at a 70% minimum (NKG), or 80% for the co-op code (NAB) and for the Law and Politics stream. International Relations (NJI) is a separate code at 70%. Windsor lists most arts majors twice: a base code at a 70% minimum and a co-op code at an 80% minimum. Same degree, same department — the co-op version asks ten points more.
Direct entry at low-70s (DLI co-op). Ontario Tech publishes nearly every major twice, a base code and a co-op code, usually at the same range.
Trent calls it Political Studies, direct entry at a 70% minimum; the co-op code (RPU) is 80%. International Political Economy (RPE) is separate. Trent publishes a minimum, and its own admissions FAQ says 'meeting the minimum does not guarantee admission'. The safety net is real: if you are not admitted to a competitive programme, Trent automatically assesses you for an alternate offer into a similar one, with no second application.
Political Science/Pre-Law (AAL)
Lakehead's political science degree is Political Science/Pre-Law, direct entry at 70% at both campuses.
Political Science (BA 4 year) (JBF)
Direct entry at 65%+ as a 4-year (JBF) or 3-year (JAQ) BA. Algoma publishes most subjects twice: a 3-year general code and a 4-year honours code, at the same floor.
