When you apply

After you apply on the Ontario Universities’ Application Centre (OUAC), you’ll get an email with instructions to create a Western Student Center account within 10 business days of applying.

In your Student Center you’ll have a To Do List with all the documents we need from you, and how you need to submit them. In most cases, we won’t need originals yet – all you’ll need to do is upload a copy to your Student Center.

You'll need to submit your grades. You may also submit required or optional supplementary forms to support your application.

We’ll ask you to resubmit if you don’t send us what we asked for or if you send it in a different way than we asked. To avoid delays, be sure to follow the instructions on your Student Center!

After you accept

If you get an offer and you accept it (hooray! 🎉), then we’ll ask you for official documents including all of your final grades.

We’ll ask for:

Academic Transcript, including:
- Proof of graduation
- All subjects you studied
- All grades you earned
(Optional) Your Advanced Placement External Exam Results
- Sent directly to Western by the College Board
- Western’s institution number is 0984
- AP courses with an exam score of 4 or higher will be considered for transfer credit

You can apply even if you haven’t graduated yet. We’ll use your mid-year or mid-term results to calculate an admissions average. In this case, we may offer you conditional admission.

If you receive an offer, the conditions of your offer will be clearly outlined in your Offer of Admission letter and on your Offer Portal. Usually, we want to see that you actually graduated, and that you kept your grades above a minimum average.

When you graduate, you'll send us your official final documents, and we'll check to see you met your conditions. If successful, we will turn your conditional offer into an unconditional offer, but we won't issue you a new offer letter.

What Are Your Chances?

Typically, students who get admitted to Western have the equivalent of at least a B (3.0) average in the Canadian grading scale.

Since you aren't studying a Canadian secondary school curriculum, we'll calculate your admission average based on curriculum, grading practices and grading scale interpretation.

Some programs are more competitive than others! So aim for the highest grades you can earn.
