If you plan to be a full-time Waterloo student, you'll apply through the Ontario Universities' Application Centre (OUAC), which handles applications to each of Ontario's universities.
Applying through the OUAC means that you'll apply and/or submit grades to the OUAC instead of having to contact multiple Ontario universities. OUAC will send your information to each Ontario university you apply to.
Ontario high school students
If you're currently registered in an Ontario high school, you'll apply using the OUAC 101 application and your high school will send your grade information to us.
All other students
You'll use the OUAC 105 application for full-time studies and you'll need to arrange for your transcripts to be sent to us. View our applying from outside of Ontario video listed below.
If you're interested in part-time or online studies, there is a separate application process.
Be sure to apply by the application deadline (February 1 for most programs).
Within two weeks of receiving your application from the OUAC, we'll email you with your Waterloo student number and any actions you might need to take.
Can you apply to more than one program at Waterloo?
Yes. You may apply to a maximum of three programs at Waterloo. If you're interested in Engineering, only one of those programs can be an Engineering program.
Applying only to Engineering programs
You can apply to one Waterloo Engineering program on your OUAC application and then use your Admission Information Form (AIF) to request consideration for an alternate Engineering program.
If we can’t accommodate you in your first-choice Engineering program (i.e., the one you chose on your OUAC application), we may be able to consider you for your alternate choice. Priority for a program may be given to those students who select it as their first choice.
Biomedical Engineering and Software Engineering are not available as alternate choices on the AIF, so you'll need to list one of those on your application if one of them is your main interest.
You'll receive instructions for completing your AIF once you've applied.
Applying to Engineering and to other programs
You can apply to one Engineering program and up to two other non-Engineering Waterloo programs that interest you.
If you're interested in an Engineering program and Architecture (which is offered by the Faculty of Engineering), you can apply to Architecture, one Engineering program, and another Waterloo program if you wish.

How do you apply to a co-op program?
To apply to a co-op program, you must check the co-op box on your Ontario Universities' Application Centre application.
If you apply to a co-op program that is also offered through the regular system of study and you're not admitted to co-op, you'll automatically be considered for the regular program if spaces are available.
Co-op and regular systems of study are available to Canadian and international students.
Applying to part-time and online studies
Part-time studies (one or two courses per term), online learning, post-degree, non-degree, and letter of permission use a different application process.
Take courses for general interest
To take courses for general interest, apply to non-degree studies (if you don't have a degree) or to post-degree studies (if you have completed an undergraduate degree).
