No. Once you submit your online application, you will not be able to make changes to it. The Office of Graduate & Postdoctoral Studies does not alter submitted applications. Please proofread your application carefully before submitting it.
The exception to this is if you need to modify referees in cases where you have applied to multiple programs. We are unable to change this through OUAC; however, we can update our systems to ensure that the appropriate individuals are being contacted for referee assessments in support of your application(s).
Should you need to change referees for a specific program, you would need to submit this request after you have paid for your applications. You would submit this request to gradapps@uoguelph.ca [1] after you have received your WebAdvisor login credentials (as you will need to submit the request using your University of Guelph email address). Please see the How do I Change or Add a Referee page [2] for more information.
