How OfferMap reaches an estimate.

The model is meant to make research comparable, not to make an admissions promise. This page shows what goes into each number, what stays out, and where uncertainty remains.

Estimate of Acceptance

The displayed percentage is a modelled planning estimate. It is not a university-published acceptance rate, an observed rate for applicants like you, or a statistically calibrated probability. Universities do not publish enough program-level applicant outcome data for OfferMap to make that claim responsibly.

  1. Prerequisite gate. If a listed prerequisite is missing or below its published minimum, OfferMap does not show a percentage.
  2. Program-specific average. OfferMap places the program's required courses into the calculation, then uses your highest remaining Grade 12 U/M marks to reach six courses.
  3. Grade position. That calculated average is compared with the midpoint and width of the program's published planning range.
  4. Selection type. Grades-led, mixed-evidence and supplemental-required programs receive different caps and uncertainty widths.
  5. Planning range. The midpoint is shown with a deliberately wide range so the interface does not imply false precision.
Grade signal · model v0.6scale = max(range width, 2) ÷ (2 × ln 2)5 + 90 ÷ (1 + e^(-(average - range midpoint) ÷ scale))

Before selection caps, the published low, midpoint and high map to approximately 35%, 50% and 65%. Using range width keeps that interpretation consistent across narrow and broad published ranges. Midpoint caps are 94% for grades-led selection, 88% for mixed selection, and 80% when a supplemental application is required. Planning ranges are ±11, ±15 and ±20 points respectively, then bounded between 3% and 97%.

Model testPlanning labelMeaning
Midpoint 75%+ and range low 55%+LikelyStronger grade evidence, still not guaranteed
Midpoint 45%+ and range low 30%+MatchProfile is reasonably aligned with published guidance
Midpoint 20%+ otherwiseReachMeaningful uncertainty or below-range evidence
Midpoint 5–19%High reachLimited grade evidence; consider alternatives

The lower end of the planning range participates in the label so a wide-uncertainty supplemental program is not called a Match too early. The displayed midpoint itself is unchanged.

Important calculation limitation: the model follows the common “prerequisites plus highest remaining 4U/M marks to total six” approach. Universities may treat repeated courses, equivalent language courses, summer/private-school marks, AP/IB courses, failed attempts or special curricula differently. The linked university rule controls.

Ontario course assumptions

The picker starts with six rows and permits up to eight because Ontario applicants generally need at least six Grade 12 U/M courses, while many semestered timetables provide space for as many as eight. “Other Grade 12 U/M course” covers valid courses that are board-, school-, language-, IB- or AP-specific.

The catalog is a practical course picker, not a promise that every Ontario school offers every listed course. Students should use the exact code shown on their timetable or transcript. See Ontario's official course descriptions ↗ and the OUAC undergraduate guide ↗.

Program ranking estimates

“Strongest” and “most attainable” are intentionally separate. Admission probability receives zero weight in Degree strength and Overall fit. A student can switch to “Likelihood to get in” when they explicitly want the percentage-based admission estimate to control the order.

Each /100 value is OfferMap's comparative research estimate within the current Ontario catalog. It is not an official university ranking, a salary forecast, a promise of employment, or a universal measure of teaching quality.

Overall fit30% degree strength + 20% career launch + 18% goal strength + 10% direct alignment + 8% experience/co-op fit + 6% location + 5% campus life + 3% flexibility

Estimate of Acceptance: 0%. Personal-preference factors are deliberately limited so convenience or social environment cannot overwhelm academic and career evidence.

A “must have” co-op choice is treated as a constraint: programs without a structured co-op option are removed before ranking. “Strong preference” remains a modest 2.4% part of Overall fit. Application strategy does not change any program score; it changes only the suggested mix of Reach, Match and Likely choices in the shortlist guide.

Evidence confidence is tracked separately. Missing published outcomes lower confidence rather than automatically lowering a program's assumed quality. School-reported employment measures are not treated as directly interchangeable because definitions, populations, response rates and time periods differ.

Third-party global rankings are not incorporated into OfferMap scores. They rank institutions or broad subjects—not named Ontario undergraduate programs—and their data is subject to separate commercial-use terms. OfferMap may link to them as optional outside context only. See the QS subject methodology ↗ and QS data-use notice ↗.

Estimated tuition

OfferMap shows a 2026–27 planning estimate for an Ontario-resident domestic student. Whenever an official university publishes a program-specific first-year amount, that figure or a rounded version is used. A range is shown when the university uses a calculator, per-unit billing, changing upper-year fees or multiple applicable fee schedules.

The figures are not quotes, invoices or four-year cost forecasts. Depending on the cited source, the display may represent tuition alone or tuition plus specified compulsory fees. The explanation beside each amount states the basis. Estimates generally exclude residence, food, books, equipment, transportation, optional charges, personal costs and sometimes ancillary or co-op fees. Scholarships and financial aid are not deducted.

Programs with changing fee structures require extra care. Ivey AEO, for example, begins with tuition charged by the student's first-entry Western program before HBA tuition applies in years 3 and 4. U of T Rotman Commerce and Computer Science can have higher deregulated fees after first year. Students must use the linked official calculator or fee schedule before accepting an offer.

Sources and update process

Prerequisites, selection notes, grade guidance and tuition estimates come first from official university pages, with OUInfo used as the Ontario program directory and cross-check. Every result links to its program page, admission source and fee source. The current research pass was completed August 19, 2026 for the 2027 entry cycle.

Published ranges can change, pages can lag, and an admission range is never a cut-off promise. Before paying application fees, verify the program, OUAC code, prerequisites, supplemental requirements, deadlines and current approval status with the university.
