IB vs AP in Canada: Which Program Suits Your Child, and What Universities Make of Each

What is the IB Diploma Programme?

The Diploma Programme (DP) is the International Baccalaureate's program for students aged 16 to 19, and it runs only at schools the IBO has authorised. In Ontario public boards it runs in Grades 11 and 12.

A DP student takes six subjects, one from each of six groups: language and literature, language acquisition, individuals and societies, sciences, mathematics and the arts. A student may swap the arts for an extra science, individuals and societies or language subject. Three or four of the six are taken at higher level (HL), which the IBO sets at 240 teaching hours, and the rest at standard level (SL), at 150. HL and SL "differ in scope but are measured according to the same grade descriptors".

Then comes the core, which every diploma student completes:

• The extended essay, "an independent, self-directed piece of research, finishing with a 4,000-word paper".
• Theory of knowledge (TOK), "assessed through an exhibition and a 1,600 word essay".
• Creativity, activity, service (CAS), which "is not formally assessed" but must be completed, and includes a CAS project.

Each subject is graded from 7 down to 1. The diploma goes to a student with at least 24 points, "subject to certain minimum levels of performance", and TOK and the extended essay together can add up to 3 more points. Six subjects at 7 plus those 3 points make 45, which is the maximum McMaster University prints for IB applicants. The IBO's own assessment pages do not print a maximum.

Exams are "the basis of the assessment for most courses", alongside teacher-marked work such as laboratory work in the sciences. The IBO runs two exam sessions a year, in May and November.

What is AP, and how does it work in an Ontario school?

Advanced Placement is a College Board program. In its own words, "Each AP course is modeled on a comparable introductory college course in the subject", and each one "culminates in a standardized college-level assessment, or AP Exam", at the end of the course. A student takes as many or as few courses as the school offers, and the Halton District School Board (HDSB) puts it plainly: "students can take 1 course or 10."

College Board's course index lists 42 AP subjects, under eight headings. They include AP Seminar and AP Research, and two AP Career Kickstart courses. Whether any given course is available depends on the school, because each one has to pass the AP Course Audit before the school may call it AP.

AP Exams are scored from 1 to 5. Most AP courses end in a written exam. The 2027 exams run over two weeks in May, 3 to 7 May and 10 to 14 May, and scores come out in early July. HDSB says AP exams "are typically 2-3 hours in length."

Some courses are assessed in other ways. For example, AP Art and Design students submit a portfolio. AP Seminar students submit performance tasks and also sit an end-of-course exam. AP Research students submit a performance task.

College Board's AP awards include AP Scholar, for a 3 or more on three or more exams, and the AP Seminar and Research Certificate, for a 3 or more in both of those courses. Two of its awards are diplomas that bundle several exams:

• AP Capstone Diploma: a score of 3 or more on AP Seminar, AP Research and four other AP Exams. Teachers of the two Capstone courses must first complete a 4-day summer workshop. College Board's award page starts with "If your school offers the AP Capstone program", so ask whether your child's school does.
• AP International Diploma: a 3 or more on 5 or more exams across 4 content areas, for students at schools outside the US or sending scores to a university outside the US. A student at an Ontario school meets that condition. College Board says it is "not a substitute for a high school diploma".

A student can also sit an AP exam without taking the course. College Board calls this an exam only section, arranged through the AP coordinator at the school where the exam is written. HDSB says "All students registered in the HDSB for the 2026-27 can participate in AP Exams through the self-study model". One detail for parents: College Board says "Your parents don’t have access to your scores, unless you’ve given them your College Board account login information."

How do IB and AP fit with the Ontario diploma?

Neither replaces the OSSD. Two York Region District School Board (YRDSB) schools, Bayview Secondary and Dr. G.W. Williams Secondary, say students in their IB Programme "earn both the IB Diploma and the Ontario Secondary School Diploma." HDSB says the same of students who complete its IB program, and describes its AP preparatory courses as "delivered through the Ontario course curriculum".

That means the Ontario requirements still apply. They include the compulsory and optional credits, the literacy requirement, at least 2 online learning credits and 40 hours of community involvement. Students who started Grade 9 more recently must also meet the financial literacy graduation requirement, which is part of the Grade 10 Career Studies course. The Ministry of Education's diploma page, updated 2 September 2026, names the start year as 2024 in one place and as the 2025-2026 school year in another, so ask the school which applies to your child.

The IB boards checked here run a Grade 9 and 10 preparation stream. TDSB (the Toronto District School Board) teaches Grades 9 and 10 at "‘Pre-IB’ level", moving through the Ontario curriculum at an accelerated pace. The IB schools at HDSB offer an IBDP Prep Program in Grades 9 and 10 "at no cost to students/ families". HDSB also runs an AP Prep Program, "a Grade 9 entry opportunity".

What do IB and AP cost in Ontario?

Ontario schools cannot charge for required learning, but the Ministry of Education lists "optional programming, such as Advanced Placement courses" as potentially eligible for fees. The Ministry's page does not name the IB. Boards do charge IB fees, and the amounts differ by board and even by school.

For the IB, the IBO publishes no fee amounts. It says assessment fees are "Charged per subject for student assessments" and that schools see the figures after logging in. Families pay through the school or board instead. These are the published board figures:

The two YRDSB schools publish different senior-year amounts, so there is no single YRDSB figure. Across these three published schedules, the four-year IB fee runs from $3,300 to $3,690, before any payment-platform fee.

AP courses can be free. HDSB says there is "no charge to participate in AP Courses" or self-study, and charges only for exams. On exam fees, two published figures differ. College Board's 2026-27 fee is $99 per exam at schools in Canada for an exam ordered on time, which means by 13 November 2026 for full-year and first-semester courses, and for exam only sections. The school's AP coordinator orders the exam, so ask the school for its own deadline. College Board's fee page does not name a currency. A $40 late fee is added to each exam ordered between 14 November 2026 and 12 March 2027, but not for courses that start after 13 November. HDSB tells its families "AP Exams have a fee of $140 - $200". College Board also says "Your school may require you to pay a higher fee than listed in the table to cover proctoring and administration costs." The figure that matters is the one your child's school quotes.

Where can a student take IB or AP in Ontario?

The IBO's school finder returned 90 Ontario schools and 184 Canadian schools offering the Diploma Programme on 13 October 2026, public and private together. That count covers Diploma Programme schools only, and it changes as schools are authorised, so check the finder for the current figure.

Within a board, the IB sits at a handful of schools. TDSB says it "has five schools that offer the International Baccalaureate program". HDSB lists four IB schools (Burlington Central, Craig Kielburger, Georgetown District and White Oaks) and AP at 11 secondary schools. At HDSB, AP reaches more schools than IB. The two are also authorised differently: College Board approves AP one course at a time, while the IBO authorises a whole school to run the Diploma Programme.

TDSB lists Grade 9 and 10 entry at all five of its IB schools. Weston CI also lists Grade 11 entry, for applicants taking Grade 10 French. Later entry depends on space: "Students will be admitted in Grade 10 or 11 if space is available. Seats will be very limited."

Applicants attend a 60-minute in-person session on Monday, 7 December 2026 (or 14 December if the weather is bad). Grade 9 applicants are assessed on Grade 7 curriculum content, and Grade 10 applicants on Grade 8 content. TDSB's applicant score is an average of the student's marks in Language, Math, Science, French, Geography and History, and every applicant also attends the session. The page does not say which grades those marks come from. Separately, it says students who met the provincial standard (75%) in Language and Mathematics, and in at least three of Science, French, History and Geography, "are eligible and encouraged to consider the program." For a seat in Grade 9, the TDSB assessment falls in December of Grade 8, and offers follow in the winter, well before Grade 11.

How do Ontario universities treat IB and AP?

Admission and credit are two separate questions. Admission is whether the university makes an offer. Transfer credit, which McMaster calls advanced credit, is university credit granted for IB or AP results.

For admission, an Ontario IB student is not admitted on the IB score. Western University says it will "assess you for admission based on your OSSD". It adds: "Your guidance office will convert your predicted and final IB scores into Ontario high school grades." The school then submits those grades through OUAC. The University of Guelph says the same: Ontario IB students "will typically have their IB courses converted into Ontario U- and M-level courses." Those are Ontario's university and university/college preparation courses. The University of Toronto makes conditional offers "on the basis of your available Grade 11 and 12 (or equivalent) marks". Our guide to the OUAC application covers how those marks travel.

The IB minimums you may see quoted (Western 27, Guelph 28, Queen's 28 excluding bonus points) are on pages written for IB Diploma applicants in general. For an Ontario public school IB student, Western and Guelph describe admission on the converted Ontario marks instead, so those minimums are not the bar to aim at.

AP reaches admission the same way at HDSB, whose AP preparatory courses are "delivered through the Ontario course curriculum", so the university sees an Ontario course mark like any other. An AP exam written through self-study has no course behind it, so it adds no Ontario course mark. Western's AP page, which sits in its section for international high school applicants, puts it this way: "We’ll accept AP courses taken at your high school to calculate your admissions average. However, we cannot admit you based on your AP exams only."

Credit comes after admission. Transfer credit is assessed once the student has accepted an offer, from official results sent directly by College Board or the IBO. U of T is blunt about it: "Results issued by your school are not acceptable." These are the published rules at the universities checked:

Queen's publishes a separate IB page and AP page for each of seven program areas: Arts, Computing, Health Sciences, Nursing, Science Options, Smith Commerce and Smith Engineering. The Queen's row above comes from all fourteen pages, each linked from the Queen's transfer credits page in Sources, and all seven IB pages say no credit is granted for TOK or the extended essay.

Some Ontario rules differ from the usual line. U of T's Faculty of Applied Science & Engineering gives no transfer credit for AP or IB. Waterloo's Engineering programs, other than Architecture, grant no first-year course exemptions for either. Queen's Smith Engineering gives no credit for IB higher level Biology, Chemistry, Computer Science, Mathematics or Physics. Its IB credit counts only toward complementary studies electives in languages, the arts, humanities and social sciences, up to 6.0 units. It also gives no credit for AP Biology, Calculus AB, Chemistry, Computer Science or Statistics. Its AP page contradicts itself on Calculus BC and Physics, so ask Queen's about those two. In the other direction, Waterloo will also consider credit for TOK and the extended essay together, with a minimum grade of B in both.

Alberta, by contrast, has a provincial transfer site that says IB credit usually needs a 6 or a 7, a higher bar than the Ontario pages above.

Does either program get preference at Canadian universities?

None of the six Ontario universities read for this guide (Western, Guelph, Toronto, Waterloo, Queen's and McMaster) states a preference for either. Where they publish credit rules for both, the usual line is IB higher level at 5 or more against AP at 4 or more. College Board itself says only that "colleges want to see that you’re taking the most rigorous coursework available to you." Pages that say universities prefer one are giving an opinion.

How do the IB and AP workloads compare?

The IB is one fixed load for two years, while an AP load depends on how many courses a student picks. An IB Diploma student carries six subjects for two years, three or four of them at 240 teaching hours, plus a 4,000-word essay, TOK and CAS. An AP student carries as many single courses as they choose. Most of those end in one May exam, which HDSB says is typically 2 to 3 hours long. No source we read measures which is harder, so we will not claim either is.

Which suits your child?

These are conditions drawn from the facts above, not a ranking.

• If your child wants depth in one or two subjects and no long research essay, AP lets them pick just those, and a 4 or more can still earn first-year credit.
• If your child likes writing, argument and a fixed timetable across every subject, the IB's core asks exactly that of every diploma student: a 4,000-word extended essay and the TOK essay, on top of six subjects.
• If your local school offers only one of the two, that usually settles it.
• If cost is the deciding factor, AP at a board such as HDSB means no course fee and a per-exam fee only, while the board IB fees published by TDSB, Bayview Secondary and Dr. G.W. Williams Secondary run from $3,300 to $3,690 over four years, before any payment-platform fee.
• If you are arriving in Ontario after Grade 9, AP can be picked up one course at a time, and boards such as HDSB let students write AP exams through self-study. TDSB lists Grade 10 entry at its five IB schools. Weston CI also lists Grade 11 entry, for applicants taking Grade 10 French. Seats in Grade 10 and 11 depend on space, and every TDSB IB applicant attends the in-person assessment in December, so ask the IB school directly.
• If university credit matters most, read the specific program's page: the caps differ by faculty. U of T Engineering gives no credit for either, and Waterloo Engineering, outside Architecture, grants no first-year course exemptions for either.

Either way, Ontario universities admit on the Grade 11 and 12 Ontario course marks.

Where Genie fits

Genie's service pages do not mention IB or AP, and Genie does not describe its teachers as IB or AP teachers. For questions about the programs themselves, the school's IB or AP coordinator and guidance counsellor are the people to ask.

What the live site does describe is lessons in Ontario school courses. Its How Genie Works page says: "Genie is built around one standard: every teacher is provincially certified, and that is checked before their profile goes live." Lessons "run 1-on-1 online around the course your child is already taking at school." The page covers "Grade 1 to Grade 12, across mathematics, the sciences, English, French and the senior Ontario courses." The subjects Genie lists include Advanced Functions, Calculus and Vectors, Chemistry and Biology, with Ontario course codes. Our guides to Grade 12 chemistry and Grade 12 biology cover two of those courses in detail.
