Canadian universities: OUAC, the Top 6, and supplementary applications

Ontario applications run through OUAC’s single Undergraduate Application (the 101/105 split merged in 2023): your background is assigned to Group A — typically current Ontario high-school students on the OSSD track — or Group B. The Top 6 average is the core, but competitive programs read far more: Waterloo’s AIF, UBC’s Personal Profile, video interviews for business.

The application process

Open the application accounts

Ontario uses OUAC, British Columbia uses EducationPlannerBC, and most other provinces apply directly on each university’s site. Account details — name spelling, date of birth, school code — must match the transcript exactly; corrections are painful.

Choose universities and programs

Different programs at one university are usually separate choices with very different cutoffs. A 2:3:2 reach / match / safety split works well — and confirm each program’s prerequisite courses.

Assemble and submit

Transcripts (transmitted by the school for Ontario day-school students), activity evidence, language scores if required, personal statements and references. Supplementary applications — AIF, Personal Profile, video interviews — run on their own deadlines.

Update marks and documents

Grade 12 midterm and final marks drive most offers and are read in scheduled batches. Conditional offers state the final marks they depend on.

Track accounts and interview

Each university opens its own portal, and notices, interview invitations and scholarship information may appear only there rather than in OUAC. Check weekly.

Compare offers and accept

Compare on more than rank: co-op access, internal transfer policy, scholarships, housing and cost of living. Then pay the deposit, select courses and apply for residence on time.

Timeline for a September start

When	What happens
September - October	Applications open: UBC and McGill early, Ontario schools through OUAC in late September, SFU and Alberta in early October.
November - December	Peak for supplementary applications and early scholarship deadlines; some engineering and business supplements close here.
Mid-January	The safe submission point for current-year applicants. Most programs are chosen by now; later applicants are limited to programs still open.
February - May	Marks upload in batches and offers roll out. An offer made before final results is normally conditional — it names the marks still to be reached, and it can be withdrawn if they are not.
June - August	Final marks upload, acceptance, deposits, course selection, residence — and study permits for international students.

Confirm each university’s dates on its own site; some programs admit on a rolling basis, where applying early means hearing early.

How the Top 6 is built — and raised

The required slots

ENG4U is required almost everywhere; engineering wants MCV4U + SPH4U (usually SCH4U too), business reads the math chain, life science reads SBI4U and SCH4U. These fill first; the remaining slots are where strategy lives.

Filling the rest

Within the requirements, take the 4U/M courses this student actually scores in. One course reliably at 95 does more for the average than a harder-looking course scraping 80.

The trend gets read too

An upward curve from Grade 11 into Grade 12 helps inside a grade band; a visible Grade 12 slide draws attention, especially against a conditional offer’s final requirement.

What OUAC and EducationPlannerBC are

OUAC is the hub linking Ontario high schools, students and Ontario universities: you choose universities and programs in one system, and it distributes your information, choices and transcript to each. For current Ontario day-school students, the school transmits marks directly — you do not upload them.

EducationPlannerBC is the British Columbia counterpart and also carries program information; UBC has admitted through it since 2021. Outside Ontario and BC, most universities still take applications on their own sites.

Grouping is assigned automatically from the background you enter — there is no form to choose. Group A has marks transmitted by the school; Group B self-documents, on different deadlines and a different flow. The application itself makes the ruling.

Common questions

Do Grade 11 marks matter?

Yes. Early rounds and some programs read Grade 11 to issue conditional offers, with Grade 12 first-term marks deciding the outcome. Marks lost in Grade 11 cost double to recover in Grade 12.

Group A vs Group B?

One OUAC Undergraduate Application, grouped automatically from the background you enter: Group A — typically current Ontario high-school students on the OSSD track — has marks transmitted by the school, while Group B self-documents. Deadlines and transcript flow differ; the application makes the ruling.

Are scholarships separate?

Entrance awards are mostly automatic on the average. Major awards — Schulich Leader, Loran and similar — need school nomination and their own materials, usually due between November and January, well ahead of the regular application.

Can the language requirement be waived?

Usually, though the terms differ by school: common routes are three to four consecutive years in an English-language system, or a specified ENG4U mark. Read the target school’s own policy rather than relying on hearsay.

How much do supplementary applications matter?

Inside a grade band they are frequently decisive. Waterloo’s AIF, UBC’s Personal Profile, and the essays and videos for Ivey or Rotman exist precisely to separate two applicants with the same average — they deserve essay-level effort.
