The universities will acknowledge when they receive your application and provide you with a list of the specific supporting documents they require to make an admission decision.
If you do not receive any communication from your selected universities after 2 to 3 weeks, contact them directly. Include your OUAC Reference Number in all communication with the universities and on all supporting documents sent to the universities.
Visit your selected universities. University open houses and campus visits are great ways to experience first-hand what campus life is like and may help you decide which university is the best fit for you.
