Post-Secondary Applications


Ontario Universities' Application Centre

A student may have their OSR residing at another public, Catholic, or private school while being registered for one or more courses with GRHS. This student will complete an Ontario Universities' Application Centre (OUAC) 101 application through their home school. GRHS will require the student to provide us with their OUAC Reference Number (YYYY-######) in order for GRHS course information to be sent to OUAC. GRHS will send all required documentation directly to OUAC on behalf of the student. There is no fee associated with this service.

A student whose OSR resides at GRHS, who is currently earning the OSSD, and who wishes to apply to universities through an OUAC account is considered a 101 applicant. This student may request that GRHS establish a Personal Identification Number (PIN) for them. Once GRHS creates the PIN, it is emailed to the student along with the required information and application instructions. The student then uses this information to log in and create a 101 Application with OUAC. Once the student has applied, all academic information from Grades 11 and 12 will be uploaded to OUAC. GRHS can provide additional guidance to students regarding the application process if required. 

For students applying to post-secondary schools outside Ontario or students who are OUAC 105 applicants, GRHS will provide post-secondary institutions a letter of enrolment, midterm report, and a final report. A fee of $30 is applicable for each school requested. Ontario College Application Service A student who applies to colleges through will require that GRHS update their account with any courses they are taking at GRHS. The student must submit their Ontario College Application Service (OCAS) Application Number (YY-###-####) or OCAS Account Number to the appropriate Guidance Coordinator at GRHS. GRHS will update the student's account with a letter of enrolment, midterm grade, and final grade upon course completion. The student must add GRHS to the academic information on their OCAS account so that we are able to update the account accordingly.
