Before you start: gather your details

The OUAC 105 (Group B) Undergraduate application is one online form that sends your details to every Ontario program you choose. It goes faster and more accurately if you collect your information first.

Your full legal name exactly as on official documents and your passport
Your academic history: schools attended and dates
Your grades / marks and the curriculum you studied (e.g. CBSE, ISC, IB, A-Levels)
The list of universities and specific programs you want to apply to
A payment method for the application and any additional program-choice fees
Contact details and a reliable email you check daily

Create your OUAC account

Begin at ouac.on.ca and open the Undergraduate application for your group. As an international, out-of-province, mature or post-secondary applicant, you use the 105 (Group B) stream. You will create an account with your email, set a password, and receive an OUAC reference number that identifies your application throughout the cycle.

Keep your login and reference number safe — you will use them to return to the form, add documents, and later check the status of each choice. Enter your personal details carefully; your name and date of birth should match your official documents to avoid problems later.

Enter your academic background and grades

Next you record your educational history: the schools you attended and the qualifications you hold or are completing. Depending on your background and the universities you choose, you may report grades within the application and you will usually also need to send official transcripts.

Follow exactly what each university asks for. Some accept self-reported grades initially and then require official documents; others want official transcripts sent directly. The OUAC and the universities specify how transcripts and English-language test results should reach them. Because the process differs by university and curriculum, confirm the current requirement for each of your choices on their official pages.

Add and order your program choices

Now add the specific programs you want. Each choice is a particular program at a particular university — not just the university — so search carefully and pick the exact program code or name.

The OUAC charges a base application fee, and an additional fee applies for each extra program choice beyond your included choices, so add deliberately. The OUAC will not forward your application to universities until your fees are paid in full, and fees are non-refundable. Check the current amounts on the OUAC Fees page before adding choices.

Add each program precisely (right campus, right program, right start term)
Review the fee impact as you add extra choices
Remove any choice you are no longer serious about before paying
Note any program that needs a supplementary application or assessment

Mind the deadlines — they are per program

For 105 (Group B) applicants there is usually no single OUAC-wide deadline. Each university — and often each program — sets its own closing date, and supplementary steps can have separate, earlier deadlines. Pay your fees by each applicable deadline, because the OUAC holds applications until payment clears.

International applicants should also leave time after admission for accepting an offer, paying deposits, and applying for a study permit through IRCC. Study-permit requirements and processing times are set by IRCC and change — this is general information, not immigration advice — so verify study-permit timelines on canada.ca and every application date on the OUAC Key Dates page and the university sites.

Submit, pay and track

Review everything once more — names, choices, grades, contact details — then submit and pay. After submitting, watch for confirmation and for instructions to access each university's applicant portal, where outstanding tasks (documents, supplementary forms, assessments) will appear.

Double-check personal details and program choices before paying
Pay the base fee plus any additional program-choice fees in full
Save your confirmation and OUAC reference number
Set up and monitor each university applicant portal and your email
Complete every required document and supplementary step on time

Frequently asked questions

Which OUAC application do I use as an international student?

You use the 105 (Group B) Undergraduate application, the stream for applicants who are not current Ontario high-school students. Start at ouac.on.ca and follow the international-applicant guidance to open the correct application.

Do I report my own grades or send transcripts?

It depends on the university and your curriculum — some accept self-reported grades at first and require official transcripts later, others want official transcripts directly. Follow each university's instructions and confirm the current requirement on its official admissions page.

How much does each program choice cost?

There is a base OUAC application fee plus an additional fee for each extra program choice beyond your included choices, and fees are non-refundable. The OUAC won't forward your application until fees are paid in full. Amounts change each cycle — check the current figures on the OUAC Fees page.

Is there one deadline for the whole OUAC 105 application?

Usually no. For Group B applicants, each university and often each program sets its own deadline, and supplementary steps may close earlier. Check every program's deadline on the OUAC Key Dates page and the university's site.

Can I change my program choices after submitting?

You can typically log back in to make certain changes, but rules and any extra fees apply, and some changes may not be possible after deadlines pass. Check the current change rules on ouac.on.ca and act before the relevant deadline.
